Due to a lack of vitamin A in the body, negative changes can occur - visual impairment, conjunctivitis, xerophthalmia, skin hyperkeratosis. In addition, people suffering from a deficiency of this vitamin are prone to diseases of the intestines and respiratory tract. Let's find out together why this is happening.
Importance of Vitamin A
Vitamin A plays an important role in the human body:
- takes part in cell growth processes;
- supports color vision;
- participates in the exchange of organic compounds;
- participates in the synthesis of sex hormones;
- supports the body's defenses;
- protects against the effects of free radicals.
Vitamin A is a fat-soluble substance that consists of a number of structurally similar compounds: retinol, dehydroretinol, retinal, retinoic acid, esters and their spatial isomers.
Retinol helps maintain a stable blood sugar level. Therefore, vitamin A is considered to be particularly important in the treatment of hypertension, diabetes and obesity.
Causes of hypovitaminosis A
Vitamin A deficiency can be caused by a violation of its absorption in the intestine. This usually occurs in chronic diseases of the intestines, liver, pancreas, celiac disease, iron deficiency anemia. Eating even a small amount of dietary fat can reduce the absorption of vitamin A. In addition, low protein intake also contributes to a decrease in vitamin A levels.
The cause of hypovitaminosis can be a significant loss of it by the body in cancer, diseases of the urinary tract and chronic infectious diseases.
At birth, the level of vitamin A in a child is reduced. But it quickly rises, since the main food of the newborn (breast milk) is rich in this vitamin. Therefore, with a healthy appetite, the baby is protected from hypovitaminosis. However, if after the transition to an adult diet, the child's diet contains a small amount of foods rich in vitamin A, this will affect his health. Age from 2 to 3 years is especially dangerous. To prevent this from happening, the baby needs to eat more vegetables, fruits, dairy products, liver, and take fortified supplements.
Signs of deficiency
Hypovitaminosis manifests itself in different ways. Its main symptom is the loss of twilight vision. Other symptoms may soon appear. The processes of keratinization of the skin and mucous membranes (mainly in the oral cavity) are violated.
Dry skin in teenagers before puberty can be a sign of a retinol deficiency. In this case, its keratinization and peeling occurs.
In adults, hypovitaminosis can cause:
- hair loss, dandruff;
- brittle nails;
- increased keratinization of the skin;
- premature aging of the skin, the formation of wrinkles;
- lacrimation in the cold;
- redness of the eyelids, the formation of mucus in the corners of the eyes;
- erectile dysfunction.
Retinol deficiency contributes to the development of dermatological diseases, increased sensitivity of tooth enamel, diseases of the digestive system (atrophic gastritis), liver cysts, pancreatic cancer, gynecological pathologies (mastopathy, breast tumors). In addition, a deficiency of this substance can cause frequent colds and chronic diseases of the upper respiratory tract, slow growth and development (in children).
The main problem associated with vitamin A deficiency is that the immune system deteriorates and the body becomes vulnerable to various infections.
Lack of carnitine causes the development of muscle necrosis. Characteristic signs of this disease: muscle pain, weakness, general malaise. Vitamin A deficiency is very dangerous and requires treatment.
Treatment
Retinol deficiency in the human body is corrected with the help of medications. To do this, the doctor prescribes the use of synthetic products containing a large amount of vitamin A.
Retinol
An effective remedy for hypovitaminosis A. It comes in capsules or liquid form (for external use). It is necessary to take the drug in accordance with the doctor's instructions. You need to follow this rule, even if your goal is prevention. The required dose is determined depending on the age, as well as the individual characteristics of the organism. For mild or moderate disorders, the daily dosage of Retinol for an adult is 33,000 IU, for a child - 5,000 IU. For prevention, they usually use 3300 IU per day (for an adult).
During pregnancy, the use of Retinol should be treated with extreme caution. Excessive amounts of this drug can lead to irreparable disorders in the development of the baby. You should also remember the dangers of Retinol when planning to conceive a child. The active component of this drug accumulates in the body.
Tocopherol
It is used in cases where there is a deficiency of vitamins A and E at the same time. Aevit is a popular remedy containing both of these vitamins.
The course of treatment usually takes several weeks. But in severe cases, one course of therapy may not be enough, additional or repeated treatment will be required.
The very first of the vitamins discovered by scientists is vitamin A. Therefore, its name comes from the first letter of the alphabet. Vitamin A is a fat-soluble vitamin that comes in two forms: provitamin A (carotene) and the original vitamin A (retinol).
The role of vitamin A in human life is very large - it stimulates the growth of new cells and slows down the aging of existing ones, normalizes redox processes, positively affects vision, as well as the formation of bones and teeth.
Vitamin A deficiency in the human body is caused by the following factors:
- lack of vitamin a in food;
- prolonged deficiency of complete proteins;
- insufficient fat intake;
- diseases of the intestines, liver, pancreas and biliary tract.
Signs of Vitamin A Deficiency
Signs of vitamin A deficiency in the body are expressed in the following:
- the appearance of wrinkles and early aging of the skin, dandruff;
- manifestation of "night blindness" (when nothing is visible in the evening). Blindness increases with time;
- dry skin, the appearance of acne;
- deterioration of the condition of teeth and gums, increased sensitivity of tooth enamel;
- fatigue, apathy, insomnia;
- "watery eyes" in the cold, redness of the eyelids, accumulation of mucus and crusts in the corners of the eyes;
- loss of erection in men and lack of arousal in women.
In children, the signs of vitamin A deficiency are as follows: reduced immunity, slow growth, fatigue, dry, rough and pale skin, children do not distinguish between blue and yellow, they develop "night blindness".
What causes a lack of vitamin A
The consequences of vitamin A deficiency are very serious. They capture almost all vital systems. So, a person can develop "night blindness", which subsequently transforms into permanent blindness. Both adults and teens develop acne. With a lack of vitamin A, various types of dermatitis can develop, due to which the skin loses its elasticity and firmness, becomes more vulnerable to all sorts of bacteria and infections.
Retinol deficiency in adults
Vitamin A deficiency in adults leads to the following ailments:
- to anemia;
- to immunodeficiency at the cellular level;
- on the part of the organs of vision - to clouding of the cornea, xerophthalmia;
- to seborrheic dermatitis, acne, skin cancer;
- to intestinal infections, diarrhea, gastritis, colitis, cysts in the liver, pancreatic cancer;
- in women - to mastopathy, cervical erosion, endocervicitis, leukoplakia;
- in men - to urinary incontinence, loss of erection and libido;
- to pneumonia, bronchitis, sinusitis, lung cancer.
Vitamin A deficiency in children
Lack of vitamin a in children leads to serious disorders of the child's immune system, while infections affect babies more often, proceeding more severely and for a longer time. In addition, serious consequences include visual impairment, damage to the skin, disruption of the normal functioning of many internal organs. Children who are deficient in vitamin A very often develop pneumonia with a high risk of death.
With a lack of vitamin a in children, dry skin can be observed. It manifests itself in the form of "goose" rough skin on the elbows, cracks on the delicate surface of the lips and dry skin of the whole body. Of course, such signs can be the cause of allergic reactions, but if there are no characteristic symptoms, then it is likely that the child simply does not receive the required dose of vitamin A and its derivatives.
Vitamin A deficiency in infants
For infants, vitamin A plays an important role. If there is a lack of vitamin a in the body of a child, then the work of the visual organ is disrupted, the formation of which occurs precisely due to retinol and its derivatives.
Mucous membranes also suffer from a lack of vitamin a in the body of infants. The skin becomes dry: it disturbs the water balance, which contributes to the nutrition of skin cells. You can replenish the reserves of vitamin A in the body of a newborn with the help of breast milk: the mother should consume more foods that contain vitamin A in large quantities. It can be: pumpkin, fish, carrots, young peas, green beans, parsley, cottage cheese, sour cream and others.
What to do with a lack of vitamin A
If there is a lack of vitamin a, then in order to replenish its reserves, it is necessary to reconsider your diet. There are several treatment options for a lack of retinol in the human body, including:
- Diet: the daily diet must contain foods high in vitamin A - butter, cheese, cream, yolk, fish oil, beef liver, cod liver and rich in carotene - bell peppers, carrots, rosehips, sea buckthorn, black currants, green crops , apricots.
- Vitamin A supplementation: Your doctor may prescribe vitamin A supplementation for up to two to four weeks. The dosage and methods of application are selected by the doctor, as there is a danger of hypervitaminosis A.
- With eye lesions, riboflavin may be used as prescribed by a doctor.
The use of vitamin A has its contraindications. So, one should be careful when taking vitamin A for pregnant women, with chronic and acute nephritis and cardiac decompensation. In addition, it is very important not to exceed the daily dose recommended by the attending physician: a single therapeutic dose should not exceed 50,000 IU for adults, and 5,000 IU for children, the daily dose is 100,000 IU for adults, 25,000 IU for children. An overdose is dangerous by intoxication, and the benefits of treatment will then be reduced to zero.
Vitamin A preparations are presented in such forms as:
- capsules of 1.5 mg;
- dragee 1 mg;
- oil solutions of various concentrations for oral administration, for injection;
- vitamin A concentrate from fish liver oil;
- cod fish oil.
Prevention of vitamin A deficiency
Vitamin A deficiency requires immediate treatment under the supervision of a specialist. The main thing in the prevention of hypovitaminosis is a balanced diet with the necessary content of vitamin A or carotene in foods. To replenish its reserves will help: carrots, green leafy vegetables, peaches, apricots, liver, butter and other products. If it is impossible to diversify food, it is recommended to take fish oil - 2-3 times a day, one tablespoon, multivitamin complexes - undevit, gendevit, hexavit, complivit, etc.
Vitamins are chemical compounds of organic origin that are found in foods and perform specific functions in the human body. Vitamins are an integral part of nutrition, as they are necessary for the proper functioning of the body. Some vitamins are included in the enzymes necessary for biochemical reactions that constantly take place in the human body, or they themselves turn into enzymes, others act as catalysts in these reactions, and others can act as hormone precursors and hormones themselves.
As of 2012, 13 chemicals are recognized as vitamins and two more are being considered for inclusion in the vitamin family. Vitamins are not the most stable compounds and lose their activity under the influence of atmospheric oxygen, moisture, acidic environment, sunlight, high temperature and other factors. This must be taken into account when preparing food - vitamins are practically not preserved during cooking, frying and other types of food processing.
Interestingly, there are substances that have effects opposite to those of vitamins. They are called antivitamins. Antivitamins are used to study the physiological role of vitamins in the human body.
Vitamins are classified into two main groups - fat-soluble and water-soluble. Fat-soluble vitamins are vitamins A, D, E, K, water-soluble vitamins are vitamin C, P, B vitamins. Fat-soluble vitamins are better absorbed when taken with fats, water-soluble vitamins do not need fats for work. Fat-soluble vitamins are able to be deposited in the body, accumulating in adipose tissue and in the liver. Water-soluble vitamins do not create a reserve, but in excess they are simply excreted.
In the early 1940s, Academician Palladin chemically created a water-soluble analogue of fat-soluble vitamin K. The substance was named vikasol. Later, water-soluble variants of other fat-soluble vitamins were also obtained.
Most of the vitamins are not synthesized in the body, and therefore must come from outside. With a lack of vitamins in the diet, numerous metabolic disorders occur, which affects the state of health and well-being of a person. Everyone knows that a lack of vitamins should not be allowed, at the same time their excess is harmful to the body. Vitamin A is on the agenda today.
Vitamin A properties
Vitamin A can be formed in the body from the initial substances brought in by food. The required daily dose of vitamin A is 300-900 micrograms for adults and 600-3000 micrograms for children. Its chemical name is retinol. The discovery of vitamin A dates back to 1913 - scientists found that it is part of the butter and yolk of chicken eggs. In 1931, its structure was described, and 15 years later, vitamin A was recreated chemically.
Vitamin A can exist in different forms. So, vitamin A includes retinoids, retinal, retinoic acid. Vitamin A is involved in many important processes in the human body. Retinal is an integral part of rhodopsin, the main visual pigment. Retinoic acid stimulates growth and development. Retinol itself is found in cell membranes and has an antioxidant effect.
All types of vitamin A are found in animal products, but retinol itself is unstable, therefore it is in combination with other substances. Plants contain precursors of vitamin A - carotenoids. In the body, carotenoids are converted to vitamin A, but some animals, such as cats, do not, meaning they cannot obtain vitamin A from plants.
In humans, most vitamin A is stored in the liver and less (10%) in the kidneys, adrenal glands, and fat. It is used in the synthesis of sex hormones, enzymes, interferon, immunoglobulin A, rhodopsin. Vitamin E supports the activity of vitamin A. In the treatment of eye disease, popularly known as "night blindness", it is used together with vitamins B2 and B3. In other diseases, vitamin D is a companion.
Vitamin A is found in plant and animal foods. In significant quantities, it is found in the liver of marine fish and mammals. People can get vitamin A in the form of carotenoids, but only a small proportion of carotenoids can be converted to vitamin A. Carotenoids are found in carrots (although the amount varies in different varieties), red bell peppers, green onions, lettuce, pumpkin, tomatoes, spinach, cabbage broccoli, parsley, soybeans and peas, and from fruits - in apples, grapes, apricots, rose hips, peaches, watermelon and melon, cherries and sea buckthorn. Of the products of animal origin, there is a lot of vitamin A in fish oil and liver, butter, cheese, milk, cottage cheese, and also, as you already know, in the yolk of eggs. Since vitamin A is a fat-soluble vitamin, it is better to eat it with fats, for example, in the form of a salad of grated carrots with sour cream or boiled eggs with mayonnaise.
Vitamin A deficiency: immunity and beyond
With a lack of vitamin A, damage to the epithelium occurs - cells, in particular, lining the mucous membrane of internal organs, vision falls, washing of the cornea with tear fluid is disturbed. In addition, there is a weakening of the immune system and growth retardation. In developing countries, vitamin A deficiency is estimated to cause approximately 250,000 to 500,000 children to lose sight each year.
Vitamin A deficiency can be primary or secondary. Primary occurs when nutrition does not supply the required dose of vitamin A, secondary occurs when fat absorption and bile production are constantly impaired, as well as chronic oxidation of vitamin A, which occurs with smoking and alcohol abuse. Vitamin A deficiency increases with a lack of zinc, which is important for those countries where there is malnutrition, malnutrition.
With hypovitaminosis A, "night blindness" occurs, or, scientifically, hemeralopia, the epithelium throughout the body suffers - from the skin and eyes to the intestines and bronchi. In the intestines, vitamin A deficiency can lead to the formation of ulcers, in the bronchi - to frequent bronchitis. As for the eyes, in addition to hemeralopia, the desquamated epithelium clogs the lacrimal canals, which disrupts the washing of the cornea with tears and can lead to xerophthalmia. Subsequently, the cornea softens, it forms an ulcerative defect and a thorn. Secondary infection accelerates corneal damage. In children, a lack of vitamin A leads to slow growth and development. With hemeralopia, the ability to see and navigate in space at dusk is impaired. If the disease is not congenital, vitamin A is the treatment.
An excess of vitamin A, or hypervitaminosis, occurs when its daily doses are significantly exceeded. Surprisingly, the excessive introduction of vitamin A into the body also affects the eyes - it causes inflammation of the cornea. In addition, there is a loss of appetite, nausea, joint pain, and an enlarged liver.
With an excess of carotenes, yellowing of the skin on the palms, soles and yellowing of the mucous membranes can be noted, which can be mistaken for jaundice. But even with a strong excess of the dose, there will be no signs of poisoning. Fatal poisoning is possible when eating the liver of a shark, polar bear, marine animals, which contains significant amounts of vitamin A. This phenomenon was first described in 1597, when a group of polar explorers was seriously poisoned by eating the liver of a polar bear.
Acute poisoning is characterized by convulsions, paralysis, and chronic poisoning is characterized by an increase in intracranial pressure, which causes headache, nausea, vomiting, impaired vision, and spontaneous (that is, without injury) fractures may occur. Excess vitamin A is also toxic to the liver and kidneys. In the treatment of poisoning, mannitol is used, which lowers intracranial pressure, and glucocorticoids, which increase the rate of destruction of vitamin A. Excess vitamin A during pregnancy and even 6 months before it can lead to malformations in the child.
Vitamin A in medicine: hemeralopia, psoriasis, infections
Medicines containing vitamin A are taken by mouth or injected into a muscle. They are used to prevent and treat hypovitaminosis, in particular, "night blindness". There are no clear criteria for hypovitaminosis A, but you can focus on its level in the blood. Together with vitamin C, vitamin A is indicated for infectious diseases. With rickets, he works in company with vitamin D. Vitamin A is also used in the form of ointments for skin diseases, for example,
Do you have dry skin, dandruff and wrinkles and don't know what to do about it? This is not an advertisement for a new anti-aging cream or shampoo, but classic signs of vitamin A deficiency. And if in an adult hypovitaminosis causes decreased vision, metabolic deterioration and premature aging, then a lack of vitamin A in childhood and adolescence can lead to much more sad consequences.
What is vitamin A
Vitamin A is a fat-soluble substance that enters the human body in the form of provitamin - carotene and retinol - vitamin A itself. "Pure" vitamin A or retinol is found in animal products - butter, whole milk, egg yolks, fish oil and liver . Provitamin A can be obtained from vegetables and fruits with yellow, green and red color: carrots, broccoli, pumpkins, apricots, peaches, apples and so on.
For the normal absorption of provitamin A, many other substances are needed.: fats, acids and vitamins of group B, vitamin E, D, minerals - calcium, phosphorus, zinc, which ensure the conversion of the inactive form of provitamin into an active compound used by the body. Because of this selectivity and "capriciousness" of vitamin A, you can often meet people of all ages suffering from hypovitaminosis. The reason for its development may be malnutrition - for example, a strict diet with the exclusion of fats and animal products, diseases of the gastrointestinal tract, endocrine pathologies, pregnancy, active growth, increased physical and psycho-emotional stress.
Importance of vitamin A in the body
The role of vitamin A in the life of our body is difficult to overestimate. This substance takes part in the synthesis of proteins, which are the "building material" of our body, redox reactions and metabolism.
Vitamin A is necessary for the antioxidant defense of the body, it interacts with free radicals, reducing their harmful effects on cells and tissues.
In addition, retinol slows down aging, participates in the growth and development of new cells, strengthens the immune system and ensures the normal functioning of the retina.
Vitamin A is also called the "vitamin of growth", since it is he who plays an important role in the formation of bone tissue and the maturation of sex hormones.
Symptoms of hypovitaminosis
It is quite simple to determine that there is not enough vitamin A in the body, the most characteristic symptom diagnosed in both children and adults is “night blindness”, a violation of twilight vision. In conditions of low light, a person does not see anything, is poorly oriented in space and cannot get used to the darkness for a long time.
In children Vitamin A deficiency symptoms can include:
- dryness and peeling of the skin;
- the appearance of cracks in the corners of the mouth, on the soles, hands, and so on;
- slowdown in physical and mental development;
- anemia.
If a child has been deficient in vitamin A for a long time, he may experience a characteristic stunting, mental retardation, dental diseases, frequent viral and bacterial infections, and eye diseases - conjunctivitis, xerosis, and so on.
Vitamin A deficiency symptoms in adults:
- dryness and premature aging of the skin, the appearance of wrinkles, folds, loss of elasticity;
- rash and peeling of the skin of the face and hands;
- dandruff, hair loss;
- frequent colds and intestinal diseases;
- deterioration in the quality of tooth enamel - teeth easily “crumble”, caries develops and bleeding gums;
- drowsiness, constant fatigue, sleep problems;
- decreased libido - this is due to the participation of vitamin A in the synthesis of hormones, including sex;
- dry eyes, conjunctivitis and night blindness.
Vitamin A deficiency - consequences
Lack of vitamin A in the diet, and therefore in the human body, can cause a variety of "troubles". And they are different for every age. So, if an adult man with a lack of vitamin A is likely to often suffer from colds, then a woman's menstrual cycle may be disrupted, and the child will have problems with growth.
The most serious consequences of hypovitaminosis for adults can be destruction of the membranes of the eyeball- clouding and softening of the cornea of the eye and a violation of color vision, and loss of visual acuity.
Vitamin A deficiency is very dangerous for the reproductive function of men and women - a violation of the formation of sex hormones can cause secondary infertility or problems during pregnancy.
For children, vitamin A deficiency can be cause of developmental delay, decrease in intellectual functions and stunting.
What to do with a lack of vitamin A?
Daily requirement for vitamin A
- In an adult male - 700-1000 mcg;
- In a woman - 600-800 mcg;
- In a pregnant woman - 700-9000 mcg;
- In children and adolescents - 400-1000 mcg, depending on age and needs.
It is strictly not recommended to exceed the indicated doses, since excess vitamin A is not excreted from the body, but accumulates in the liver. And an excess of vitamin A can be much more dangerous than its lack - hypervitaminosis causes toxic damage to the liver, spleen, disruption of the intestines and endocrine organs. Fortunately, you can get vitamin A hypervitaminosis only by taking synthetic vitamins and at the same time greatly exceeding the dose.
To avoid hypo- and hypervitaminosis, you should try to introduce more foods into your diet that contain vitamin A in a “ready-made” form and provitamin A.
- liver;
- egg yolks;
- butter;
- cream;
- cottage cheese.
- carrot;
- sweet potato;
- broccoli;
- Sweet pepper;
- pumpkin;
- potato;
- avocado;
- melon;
- peach;
- apricot.
In order to avoid a lack of vitamin A in the body, it is not at all necessary to eat a piece of liver daily, eating it with cauliflower. It is enough to add whole dairy products to the diet at least 3 times a week - full-fat cottage cheese and cream, unpasteurized milk, cheeses with a high percentage of fat and butter. And also do not forget about meat dishes and eggs and eat 100-200 grams of any fresh or baked vegetables and fruits daily.
So 100 g of carrots contains 300% of the daily norm of carotene, in beef liver of the same weight - 330%, but pumpkin, melons, peaches can boast only 60-70%.
For those people who have been officially confirmed the diagnosis: "vitamin A hypovitaminosis", you can recommend fish oil capsules or vitamin A capsules.
Vitamins A and E play an important role in our body. With their lack, our eyesight, hair and nails suffer. Unfortunately, many women associate these symptoms with poor-quality cosmetics or age-related changes.
The role of vitamin A in our body
This vitamin has two forms: carotene and retinol. Retinol is found in animal products. Also, our body absorbs alpha, beta and gamma-carotenes from foods.
Alpha-carotene
This provitamin can be found in kiwifruit, melon, beans, potatoes, carrots, and pumpkins. However, in order for the provitamin to be preserved, all foods must be consumed raw or steamed. With prolonged heat treatment, all useful substances evaporate. The lack of this substance leads to disorders in the immune system, to problems with the skin and vision. Regular consumption of foods with alpha-carotene reduces the incidence of cancer.
beta-carotene
This substance can be found in orange and yellow foods: carrots, bell peppers, peaches and chicory. Its regular use reduces the risk of cardiovascular and oncological diseases.
What does a lack of vitamin A lead to?
It has already been mentioned above that a lack of vitamin A in the body can lead to serious disorders. To notice the lack of this vitamin in time, pay attention to the following symptoms:
The appearance of wrinkles and rapid aging of the skin;
vision problems;
Increased fatigue, poor health, loss of strength, insomnia, apathy;
Skin diseases (increased dryness, acne, etc.);
Respiratory tract diseases;
Deterioration of the condition of the hair;
Problems with gums and teeth (hypersensitivity);
Problems with intimate life (decreased libido, loss of erection).
In order for vitamin A to be absorbed, elements such as iron and zinc are needed. With constant nervous breakdowns, diets, diseases, malnutrition, vitamin A reserves are quickly exhausted in our body.
Zinc ensures the transport of vitamin A from the liver. Zinc is also responsible for its accumulation and storage in body tissues. This vitamin plays an important role in metabolic processes. Especially strongly the lack of vitamin is reflected in women: hair and nails become brittle, dandruff and skin problems appear. Indigestion and diarrhea may occur.
Too much vitamin A
An excess of this vitamin is also bad for the body. Therefore, carefully read the instructions for vitamin complexes and, if necessary, consult a doctor. Symptoms of hypervitaminosis: bleeding, which often causes miscarriage, bad mood and apathy, nausea, indigestion, severe headaches.
Vitamin E
This vitamin is just as important for women's health as vitamin A. It helps fight free radicals and has antioxidant properties. In addition, this vitamin plays a significant role in the bearing of the fetus. There are eight forms in which vitamin E is present.
What does a lack of vitamin E lead to?
It is not for nothing that in this article we are considering two vitamins at once: A and E. The thing is that they are very important for the female body. With a lack of these vitamins, a woman will not be able to conceive a child, and a man will not be able to fertilize. There are frequent cases of miscarriages. Therefore, it is imperative to ensure that these vitamins are supplied in the right amount to our body.
Vitamin E deficiency affects the nervous system, the work of the pituitary gland and the thyroid gland. The first symptoms that should alert you are lethargy, apathy, poor health, general weakness, emotional instability. As soon as you notice the presence of these symptoms in yourself, immediately consult a doctor. You will be assigned a comprehensive examination, which will include an examination of the thyroid gland, liver and gallbladder.
With beriberi, a person becomes too irritable. Severe anemia may occur. Prolonged beriberi can even lead to the development of serious diseases such as thromboembolism and cancer. The main function of vitamin E is to protect the body from the effects of harmful substances.
Sometimes a course of treatment with vitamin E is prescribed if the girl is sick with mastopathy, fibroplasia, intraventricular bleeding. With such diseases, not only drug treatment is prescribed, but also a special diet.
Fortunately, vitamin E and A deficiency is very rare. But it can occur if the human body does not absorb fats well. Also, beriberi affects women whose age has exceeded 50 years. People who use alcohol or drugs are at risk of beriberi. However, most often doctors are faced with cases where the lack of vitamins is associated with various diets.
If you have received a burn or injury, have undergone surgery, then you must definitely include foods that contain vitamin E in your diet. This will help the body recover faster.
What does an excess of vitamin E lead to?
The daily requirement in vitamin E is only 14 grams. However, during pregnancy, in the presence of certain diseases or strong physical exertion, the dose of the vitamin is increased several times. As a rule, an excess of this vitamin does not affect our body in any way, but still you should not abuse it.
Where to find vitamin E?
If a person monitors his diet, then he is unlikely to encounter beriberi. Vitamin E is found in eggs, milk, nuts, grains, seeds and grass, as well as vegetables. The daily need for a vitamin can be compensated by pharmacy multivitamin complexes or special preparations. A lot of this vitamin is found in sunflower, sesame and hemp oil. But keep in mind that in order for this vitamin to be normally absorbed, it is necessary to eat fatty foods.
How to overcome beriberi folk remedies
It is very easy to make up for the lack of vitamins A and E with the help of ordinary foods. To do this, include in your diet vegetable salads, which are prepared from such ingredients: parsley, celery, dill, sorrel and carrots. At least once a week, eat a vinaigrette seasoned with vegetable or olive oil. Do not forget that foods that have undergone heat treatment lose their beneficial properties.
Asparagus
This product contains a large amount of vitamins A and E. To replenish the reserves of vitamins, it is recommended to use this product at least once every two weeks. However, you need to cook asparagus in a double boiler or at least in the oven. Its regular use not only replenishes the reserves of vitamins, but also helps to cleanse the intestines of antioxidants.
Sea fish
Fatty fish varieties contain many vitamins, including A and E. Choose from varieties such as mackerel, salmon, tuna, salmon. Such fish is rich in omega fatty acids, which help in the fight against excess weight.
Liver
The liver is a very useful product that can provide our body with various vitamins and substances. Previously, diseases such as night blindness and anemia were treated with this product.
