Vitamin deficiency in pregnant women: consequences for the mother and child
I. Introduction to the theme of vitamin deficiency during pregnancy
Pregnancy is a period of significant physiological changes in the body of a woman, requiring increased consumption of nutrients, including vitamins and minerals. Ensuring the adequate receipt of these nutrients is critical of the health of both the mother and the developing fetus. The deficiency of vitamins during pregnancy can lead to serious complications affecting various aspects of the health of the mother and child, including the development of the fetus, the course of pregnancy, childbirth and the state of health of the child after birth. Understanding the importance of vitamin support and timely diagnosis and correction of deficits are key to ensure a successful outcome of pregnancy.
II. General principles of vitamin support of pregnant women
A. Features of vitamins metabolism during pregnancy: During pregnancy, significant changes occur in the metabolism of vitamins. The volume of blood increases, which leads to hemoding and a decrease in the concentration of some vitamins in plasma. The growing fetus actively uses vitamins for its growth and development, which also helps to reduce maternal reserves. Hormonal changes characteristic of pregnancy affect absorption, metabolism and excretion of vitamins. For example, an increased level of estrogens can affect the metabolism of vitamin D and B vitamins B. It is important to take these changes in when evaluating the status of vitamins and determining the necessary dosage.
B. The role of a balanced diet: The basis of vitamin support of pregnant women is a balanced diet, including a variety of products rich in vitamins and minerals. The diet should contain a sufficient amount of fruits, vegetables, whole grain products, low -fat protein and healthy fats. It is important to give preference to unprocessed products, as they contain more nutrients. Preparation should be sparing in order to minimize the loss of vitamins. For example, steaming or baking is preferable to frying. The use of empty calories, such as products with a high content of sugar and saturated fats, should be avoided, since they do not contain beneficial nutrients and can prevent the absorption of vitamins.
C. Indications for the purpose of vitamin additives: Despite the importance of a balanced diet, in most cases, pregnant women are recommended to take vitamin supplements to ensure sufficient intake of certain vitamins and minerals. This is due to the fact that satisfying increased needs for nutrients only due to nutrition is often difficult, especially in the presence of certain risk factors, such as multiple pregnancy, vegetarianism, diseases of the gastrointestinal tract, leading to impaired absorption, or adverse socio-economic conditions. The appointment of vitamin additives should be carried out by a doctor on the basis of an individual assessment of the health status of a woman, her diet and test results.
D. Principles of choosing vitamin complexes: When choosing vitamin complexes for pregnant women, several factors should be taken into account. Firstly, it is important to choose complexes designed specifically for pregnant women, as they contain the optimal ratio of vitamins and minerals necessary during this period. Secondly, you should pay attention to the form of vitamins. Some forms of vitamins are better absorbed by the body than others. For example, a folate is preferable to folic acid for women with genetic options affecting the metabolism of folic acid. Thirdly, it is important to consider the presence of allergies or intolerance to certain components of the vitamin complex. Fourth, you should choose complexes from trusted manufacturers guaranteeing the quality and safety of products. Fifthly, it is important to consult a doctor before taking any vitamin complex.
E. Safety and dosage of vitamins: It is important to comply with the recommended dosage of vitamins, since excessive consumption of some vitamins can be harmful to the health of the mother and child. For example, an overdose of vitamin A can lead to malformations of the fetus. The dosage of vitamins should be determined by the doctor, taking into account the individual needs of the woman. The simultaneous use of several vitamin complexes containing the same vitamins should be avoided to avoid overdose. In the event of any side effects after taking vitamin additives, you should immediately consult a doctor. Vitamins should be stored inaccessible to children.
III. Vitamin D
A. The role of vitamin D in pregnancy: Vitamin D plays a key role in the regulation of the metabolism of calcium and phosphorus necessary for the formation of bone tissue of the fetus. It is also important for immune function, cellular growth and neuromuscular function. During pregnancy, vitamin D supports the health of the mother and contributes to the normal development of the skeleton, teeth and the child’s immune system. Vitamin D deficiency is associated with an increased risk of development of preeclampsia, gestational diabetes, premature birth and low birth weight.
B. Causes of vitamin D deficiency in pregnant women: The main causes of vitamin D deficiency in pregnant women are insufficient exposure to the sun, insufficient consumption of products rich in vitamin D, and violations of vitamin D absorption. Out of the sun is the main source of vitamin D, since under the influence of ultraviolet rays in the skin, vitamin D is synthesis in the winter and in regions with low sunny activity of vitamin synthesis D in the skin is reduced. Insufficient consumption of products rich in vitamin D, such as fatty fish (salmon, herring, mackerel), egg yolks and enriched products (milk, yogurt, cereals), also contributes to the development of deficiency. Some diseases of the gastrointestinal tract, such as Crohn and Celiac disease, can violate the absorption of vitamin D. Obesity is also associated with a lower level of vitamin D in the blood, since vitamin D accumulates in adipose tissue and becomes less accessible to the body. Dark women are also more susceptible to vitamin D deficiency, since melanin in the skin reduces the synthesis of vitamin D under the influence of sunlight.
C. The consequences of vitamin D deficiency for the mother: Vitamin D deficiency in pregnant women can lead to a number of complications, including an increased risk of pre -eeclampsia, gestational diabetes, bacterial vaginosis, postpartum depression and increased susceptibility to infections. Preeclampsia is a serious complication of pregnancy, characterized by an increase in blood pressure and proteinuria. Gestational diabetes is a form of diabetes that develops during pregnancy. Bacterial vaginosis is a vaginal infection that can increase the risk of premature birth. Postpartum depression is a condition characterized by a feeling of sadness, anxiety and fatigue after childbirth. Vitamin D plays an important role in the immune function, so its deficiency can weaken the immune system and make a woman more susceptible to infections.
D. The consequences of vitamin D deficiency for the child: The deficiency of vitamin D in the mother during pregnancy can negatively affect the development of the child, increasing the risk of rickets, hypocalcemia, growth retardation, weakening of the immune system and increased susceptibility to allergic diseases. Rickets are a disease of bones that occurs due to a lack of vitamin D and calcium. Hypokalcemia is a condition characterized by a low level of calcium in the blood. Growth delay is a condition in which the child grows slower than expected. Vitamin D plays an important role in the development of the immune system, therefore its deficiency can weaken the child’s immune system and make it more susceptible to infections and allergic diseases. Some studies also connect the deficiency of vitamin D in a mother with an increased risk of developing autism and schizophrenia in a child in the future.
E. Diagnosis and treatment of vitamin D: Diagnosis of vitamin D deficiency is based on measuring the level of 25-hydroxyvitamin D (25 (OH) D) in the blood. Level 25 (OH) D is less than 20 ng/ml is considered a deficiency, the level of 20 to 30 ng/ml is considered insufficiency, and the level above 30 ng/ml is considered sufficient. Treatment of vitamin D deficiency includes the use of vitamin D. The dosage of vitamin D should be determined by the doctor, taking into account the degree of deficiency and individual needs of the woman. It is usually recommended to take 1000-2000 IU vitamin D per day during pregnancy. In some cases, a higher dose of vitamin D may be required, especially with severe deficiency. It is also important to ensure sufficient calcium consumption with food or in the form of additives. Regular stay in the sun can also help increase vitamin D levels, but precautions should be observed to avoid sunburn.
IV. Folic acid deficiency (vitamin B9)
A. The role of folic acid in pregnancy: Folic acid (vitamin B9) plays a decisive role in cell division, tissue growth and the formation of the fetal nerve tube in the first weeks of pregnancy. Sufficient consumption of folic acid reduces the risk of developing defects in the nervous tube, such as the cleft spine (Spina Bifida) and anencephaly. Folic acid is also important to prevent megaloblastic anemia in the mother and maintain the health of the placenta.
B. The causes of folic acid deficiency in pregnant women: The main causes of folic acid deficiency in pregnant women are insufficient consumption of products rich in folic acid, such as green leafy vegetables, legumes, citrus and enriched products (cereals, bread, pasta), as well as violations of suction of folic acid. Some drugs, such as anticonvulsants and methotrexate, can reduce the level of folic acid in the body. Alcohol can also prevent the absorption of folic acid. Genetic factors, such as MPFR polymorphisms, can affect folic acid metabolism and increase the need for folic acid. Multiple pregnancy also increases the need for folic acid.
C. The consequences of folic acid deficiency for the mother: Folic acid deficiency in pregnant women can lead to megaloblastic anemia, increased risk of developing preeclampsia, placental detachment and premature birth. Megaloblastic anemia is a form of anemia, characterized by the presence of large, immature red blood cells in the blood. The detachment of the placenta is a condition in which the placenta is separated from the wall of the uterus to childbirth.
D. The consequences of folic acid deficiency for the child: The deficiency of folic acid in the mother during pregnancy can increase the risk of developing defects in the nervous tube, such as the crevice of the spine and anencephaly. A cleft spine is a congenital defect in which the spinal cord does not completely close. Anencephalus is a congenital defect in which the brain does not completely develop. Folic acid deficiency can also increase the risk of developing other congenital defects, such as heart defects, cleft lips and sky, as well as low birth weight. Some studies associate a deficiency of folic acid in a mother with an increased risk of developing autism in a child in the future.
E. Diagnosis and treatment of folic acid deficiency: Diagnosis of folic acid deficiency is based on measuring the level of folic acid in the blood. The level of folic acid is less than 4 ng/ml is considered a deficiency. Treatment of folic acid deficiency includes taking folic acid additives. The recommended dose of folic acid for pregnant women is 400-800 mcg per day. Women with a high risk of developing defects in the nervous tube, such as women who have previously had children with nervous tube defects, or women with genetic options affecting the metabolism of folic acid, may require a higher dose of folic acid. It is important to start taking folic acid before conception and continue to reception during the first trimester of pregnancy.
V. Vitamin B12 deficiency (cobalamin)
A. The role of vitamin B12 in pregnancy: Vitamin B12 (cobalamin) is necessary for the normal functioning of the nervous system, the formation of red blood cells and DNA synthesis. During pregnancy, vitamin B12 supports the health of the mother and contributes to the proper development of the nervous system and brain of the child. Vitamin B12 deficiency can lead to neurological disorders, anemia and growth retardation in a child.
B. Causes of vitamin B12 deficiency in pregnant women: The main causes of vitamin B12 deficiency in pregnant women are insufficient consumption of products rich in vitamin B12, such as meat, fish, eggs and dairy products, violations of the absorption of vitamin B12 and vegetarianism or veganism. Vitamin B12 is found only in animal products, so vegetarians and vegans are at risk of developing vitamin B12 deficiency. Some diseases of the gastrointestinal tract, such as atrophic gastritis and Crohn’s disease, may disrupt the absorption of vitamin B12. Taking some drugs such as metformin and proton pump inhibitors can also reduce vitamin B12 vitamin in the body. Acting is also associated with a lower level of vitamin B12 in the blood.
C. The consequences of vitamin B12 deficiency for the mother: Vitamin B12 deficiency in pregnant women can lead to megaloblastic anemia, neurological disorders, such as fatigue, weakness, numbness and tingling in the limbs, depression and psychosis. Megaloblastic anemia is a form of anemia, characterized by the presence of large, immature red blood cells in the blood. Neurological disorders can be irreversible if vitamin B12 deficiency is not eliminated in a timely manner.
D. The consequences of vitamin B12 deficiency for the child: Vitamin B12 deficiency in the mother during pregnancy can negatively affect the development of the child, increasing the risk of developing neurological disorders, such as developmental delay, irritability, hypotension and convulsions. Vitamin B12 deficiency can also increase the risk of developing megaloblastic anemia, growth retardation and visual impairment in a child. Some studies associate the deficiency of vitamin B12 in a mother with an increased risk of developing autism in a child in the future.
E. Diagnosis and treatment of vitamin B12 deficiency: Diagnosis of vitamin B12 deficiency is based on measurement of vitamin B12 levels in the blood. The level of vitamin B12 is less than 200 pg/ml is considered a deficiency. However, for a more accurate diagnosis of vitamin B12 deficiency, it may require measurement of the level of methylmalonic acid (MMA) and homocysteine in the blood. Increased levels of MMA and homocysteine can indicate a deficiency of vitamin B12, even if the level of vitamin B12 in the blood is within normal limits. Treatment of vitamin B12 deficiency includes the use of vitamin B12 additives. The dosage of vitamin B12 should be determined by the doctor, taking into account the degree of deficiency and individual needs of the woman. In severe cases, vitamin B12 deficiency may require the introduction of vitamin B12 intramuscularly. It is recommended to regularly take vitamin B12 or consume enriched products regularly.
VI. Vitamin A deficiency
A. The role of vitamin A in pregnancy: Vitamin A is necessary for vision, immune function, growth and development of cells. During pregnancy, vitamin A plays an important role in the development of the eyes, heart, lungs and other organs of the child. It is also important for maintaining the health of the skin and mucous membranes of the mother.
B. Causes of vitamin A deficiency in pregnant women: Vitamin A deficiency in pregnant women is rare in developed countries, but can be common in developing countries where the food is limited. The main causes of vitamin A deficiency are insufficient consumption of products rich in vitamin A, such as liver, egg yolks, dairy products and enriched products, as well as disorders of vitamin A absorption. vitamin A.
C. The consequences of vitamin A deficiency for the mother: Vitamin A deficiency in pregnant women can lead to night blindness, dry eyes, increased susceptibility to infections and anemia. Night blindness is a condition in which vision worsens in low light conditions. Dry eye is a condition in which the eyes do not produce enough tears. Vitamin A plays an important role in the immune function, so its deficiency can weaken the immune system and make a woman more susceptible to infections.
D. The consequences of vitamin A deficiency for the child: During pregnancy, the deficiency of vitamin A can negatively affect the development of the child, increasing the risk of developing eye diseases, such as xerophthalmia and keratomulation, increased susceptibility to infections, growth retardation and innate defects. Xerophthalmia is a condition characterized by dryness of the cornea and conjunctiva. Keratomulation is a condition characterized by softening and destruction of the cornea. Vitamin A plays an important role in the development of the immune system, so its deficiency can weaken the child’s immune system and make it more susceptible to infections.
E. Hypervitaminosis A and its danger: It is important to note that excessive consumption of vitamin A during pregnancy can be toxic and lead to congenital defects, especially in the first trimester. High doses of vitamin A (more than 10,000 IU per day) can increase the risk of developing heart defects, nervous system and limbs in a child. Therefore, pregnant women are not recommended to take additives with a high content of vitamin A, especially in the form of retinol. A preferred source of vitamin A is products rich in beta carotene, which the body converts into vitamin A as necessary.
F. Diagnosis and treatment of vitamin A deficiency: Diagnosis of vitamin A deficiency is based on measuring vitamin A in the blood. The level of vitamin A is less than 20 μg/DL is considered a deficiency. Treatment of vitamin A deficiency includes the use of vitamin A additives. The dosage of vitamin A should be determined by the doctor, taking into account the degree of deficiency and individual needs of the woman. It is important to be careful not to exceed the recommended dose of vitamin an.
VII. Vitamin C deficiency
A. The role of vitamin C in pregnancy: Vitamin C (ascorbic acid) is a powerful antioxidant that protects the cells from damage by free radicals. It is also necessary for the synthesis of collagen, an important component of the skin, bones, cartilage and blood vessels. During pregnancy, vitamin C supports the immune system of the mother, promotes healing of wounds and helps to absorb iron.
B. Causes of vitamin C deficiency in pregnant women: Vitamin C deficiency in pregnant women is rare in countries with a developed healthcare system, where various foods are available. The main causes of vitamin C deficiency are insufficient consumption of products rich in vitamin C, such as citrus fruits, berries, pepper, broccoli and spinach, as well as smoking. Smoking reduces the level of vitamin C in the body.
C. The consequences of the deficiency of vitamin C for the mother: Vitamin C deficiency in pregnant women can lead to a scurvy characterized by weakness, fatigue, bleeding gums, slownessed healing of wounds and joint pain. Cing is a rare disease, but can occur with prolonged insufficient consumption of vitamin C. Vitamin C deficiency can also increase the risk of anemia, since vitamin C helps to absorb iron.
D. The consequences of vitamin C deficiency for the child: The deficiency of vitamin C in the mother during pregnancy can negatively affect the development of the child, increasing the risk of the development of sorrow (children’s scurvy), characterized by hemorrhages, pain in bones and growth retardation. Vitamin C deficiency can also increase the risk of premature birth and low birth weight.
E. Diagnosis and treatment of vitamin C deficiency: Diagnosis of vitamin C deficiency is based on measuring vitamin C levels in the blood. The level of vitamin C is less than 0.2 mg/DL is considered a deficiency. Treatment of vitamin C deficiency includes the use of vitamin C additives. The recommended dose of vitamin C for pregnant women is 85 mg per day. It is also important to use a sufficient number of products rich in vitamin C.
VIII. Deficiency of other vitamins (E, B1, B2, B3, B6)
A. Vitamin E: Vitamin E is an antioxidant that protects the cells from damage by free radicals. It is also important for immune function and skin health. The deficiency of vitamin E in pregnant women is rare, but can increase the risk of preeclampsia and premature birth. The recommended dose of vitamin E for pregnant women is 15 mg per day.
B. Vitamin B1 (TIAMIN): Vitamin B1 is necessary for the metabolism of carbohydrates and the normal functioning of the nervous system. Vitamin B1 deficiency in pregnant women can lead to Beri Berie, characterized by weakness, fatigue, edema and heart failure. The recommended dose of vitamin B1 for pregnant women is 1.4 mg per day.
C. Vitamin B2 (Riboflavin): Vitamin B2 is necessary for energy metabolism and health of the skin and mucous membranes. Vitamin B2 deficiency in pregnant women can lead to cracks in the corners of the mouth, inflammation of the tongue and dermatitis. The recommended dose of vitamin B2 for pregnant women is 1.4 mg per day.
D. Vitamin B3 (Niacin): Vitamin B3 is necessary for energy metabolism and health of the skin and nervous system. Vitamin B3 deficiency in pregnant women can lead to Pellagra, characterized by dermatitis, diarrhea and dementia. The recommended dose of vitamin B3 for pregnant women is 18 mg per day.
E. Vitamin B6 (Pyridoxin): Vitamin B6 is necessary for the metabolism of amino acids and the synthesis of neurotransmitters. Vitamin B6 deficiency in pregnant women can lead to nausea, vomiting, anemia and neurological disorders. Vitamin B6 can also help reduce nausea and vomiting during pregnancy. The recommended dose of vitamin B6 for pregnant women is 1.9 mg per day.
IX. Diagnosis and prevention of vitamin deficiency in pregnant women
A. Screening for vitamin deficiency: Regular screening for vitamin deficiency is an important part of prenatal care. The doctor may prescribe blood tests to determine the level of various vitamins and minerals. Screening is especially important for women with risk factors for the development of vitamin deficiency, such as vegetarianism, veganism, diseases of the gastrointestinal tract, multiple pregnancy and adverse socio-economic conditions.
B. Nutrition recommendations: Pregnant women are recommended to use a variety of products rich in vitamins and minerals. The diet should include a sufficient amount of fruits, vegetables, whole grain products, low -fat protein and healthy fats. It is important to give preference to unprocessed foods and cook food in a gentle way to minimize the loss of vitamins.
C. Vitamin additives: In most cases, pregnant women are recommended to take vitamin additives to ensure sufficient receipt of certain vitamins and minerals. Vitamin complexes for pregnant women should contain the optimal ratio of folic acid, vitamin D, iron, calcium and other important nutrients. The dosage of vitamins should be determined by the doctor, taking into account the individual needs of the woman.
D. Pregnant training: It is important to teach pregnant women on nutrition and vitamin support. Women should be informed about the role of vitamins in pregnancy, the causes of vitamins deficiency and consequences for the mother and child. Training can be carried out individually or in groups, as well as using information materials such as brochures, booklets and websites.
E. Vitamin intake control: The doctor must control the intake of vitamin additives to a pregnant woman to make sure that she complies with the recommended dosage and does not experience any side effects. A woman should inform the doctor about any problems or issues related to the intake of vitamins.
X. New studies in the field of vitamin support of pregnant women
A. The role of the intestinal microbiotic in the assimilation of vitamins: New studies show that the intestinal microbiota plays an important role in the assimilation of vitamins. Different types of bacteria in the intestines can synthesize vitamins, such as vitamin K and B vitamins B. Intestinal dysbiosis can disrupt the absorption of vitamins and increase the risk of vitamin deficiency. Probiotics and prebiotics can improve the composition of the intestinal microbiots and increase the absorption of vitamins.
B. Genetic factors and the need for vitamins: Genetic factors can affect vitamins metabolism and determine the individual need for vitamins. For example, MPFR polymorphisms can affect folic acid metabolism and increase the need for folic acid. Personalized vitamin support based on genetic testing can be more effective than standard recommendations.
C. The influence of epigenetic factors on the vitamin status: Epigenetic factors, such as diet, stress and the effects of toxins, can affect vitamin status. These factors can change the expression of genes involved in vitamins metabolism. The study of the influence of epigenetic factors on the vitamin status can help develop more effective strategies for the prevention and treatment of vitamin deficiency.
D. New forms of vitamin additives: New forms of vitamin additives are developed, which are better absorbed by the body. For example, liposomal vitamins and microcapsulated vitamins have increased bioavailability. These new forms of vitamin additives can be especially useful for women with vitamins absorption.
E. The role of vitamins in the prevention of pregnancy complications: Studies are conducted on the role of vitamins in the prevention of pregnancy complications, such as preeclampsia, gestational diabetes and premature birth. Preliminary results show that vitamin support can reduce the risk of developing these complications.
XI. Conclusion
Adequate vitamin support during pregnancy is a critical factor for ensuring the health of the mother and child. Despite the fact that a balanced nutrition should be the basis of the diet of a pregnant woman, taking vitamin additives in most cases is necessary to meet increased needs for vitamins and minerals. Timely diagnosis and correction of vitamin deficiency can reduce the risk of pregnancy complications and ensure the healthy development of the child. Further studies in the field of vitamin support of pregnant women will help to develop more effective strategies for the prevention and treatment of vitamin deficiency and improve pregnancy outcomes.
