I. Introduction to vitamin D and pregnancy
A. The importance of vitamin D for the health of the mother and child
Vitamin D is a fat -soluble vitamin that plays a key role in many vital functions of the body. It is often called “solar vitamin”, since it is produced in the skin under the influence of ultraviolet rays of type B (UVB). In addition, vitamin D can be obtained from some foods and additives.
For the health of the mother and the child during pregnancy, vitamin D is of tremendous value. It is necessary to maintain the health of bones and teeth, both in the mother and in the developing fetus. Vitamin D is involved in the regulation of the level of calcium and phosphorus in the blood, which is critically important for the formation of the skeleton of the child. In addition, vitamin D supports the immune system, helps to fight infections and inflammations, which is especially important during pregnancy, when the woman’s immune system undergoes significant changes. The low level of vitamin D can increase the risk of various complications, both in the mother and the child, which makes its sufficient level critically important.
B. The role of vitamin D during pregnancy
During pregnancy, the need for vitamin D increases, since this vitamin is necessary to maintain the health of the mother and ensure the optimal development of the fetus. Vitamin D plays a multifaceted role:
- Development of the fetal skeleton: Vitamin D provides the correct absorption of calcium and phosphorus necessary for the formation of strong bones and teeth in a child. Vitamin D deficiency can lead to rickets in a newborn, a disease characterized by weak and soft bones.
- Immune function: Vitamin D supports a healthy immune system in the mother and is transmitted to the child, providing him with infections in the first months of life. It helps to regulate the immune response, reducing the risk of autoimmune diseases and allergies.
- The growth and development of the fetus: Vitamin D is involved in the regulation of cellular growth and differentiation, which is necessary for the proper development of organs and fetal systems. It also affects the development of the brain and nervous system.
- Reducing the risk of pregnancy complications: A sufficient level of vitamin D is associated with a decrease in the risk of developing preeclampsia (high blood pressure and proteinuria), gestational diabetes (diabetes developing during pregnancy), premature birth and low weight at birth.
C. The consequences of vitamin D deficiency during pregnancy
Vitamin D deficiency during pregnancy may have serious consequences for the health of the mother and child.
- For mother: Vitamin D deficiency can lead to:
- Osteomlation: Softening of bones, which increases the risk of fractures.
- Muscle weakness and pain: Wet muscle function and increased fatigue.
- Increased risk of preeclampsia and gestational diabetes: Complications of pregnancy, which can be dangerous for the mother and child.
- Increased risk of cesarean section: Because of the weakness of bones and muscles.
- For a child: Vitamin D deficiency can lead to:
- Ricky: The disease characterized by weak and soft bones.
- Low Birth weight: Which increases the risk of health problems in the future.
- Development of development: Violations in the growth and development of bones and muscles.
- Increased risk of diseases in the future: Including autoimmune diseases, type 1 diabetes and asthma.
- Weakened immune system: Teenage to infections.
Given these serious consequences, it is extremely important to ensure a sufficient level of vitamin D during pregnancy. This can be done using sunlight, diet and additives, as recommended by a doctor.
II. Sources of vitamin D
A. Sunlight
- Vitamin D synthesis mechanism under the influence of sunlight
Sunlight is the main source of vitamin D for most people. When ultraviolet rays of the type B (UVB) reach the skin, they interact with 7-dehydrocholesterol, the predecessor of vitamin D, which is present in the skin. As a result of this reaction, 7-dehydrocholesterol is converted into previtamin D3. Previtamin D3 is then converted into vitamin D3 (cholecalciferol) under the influence of heat. Vitamin D3 is then transported to the liver, where it is hydroxylated to 25-hydroxyvitamin D [25(OH)D]also known as calciol. This calciol is the main form of vitamin D measured in blood tests to determine the level of vitamin D in the body. Then calciol is transported to the kidneys, where it is hydroxylated once again to 1.25-dihydroxyvitamin D [1,25(OH)2D]also known as calcitriol. Calcitriol is an active form of vitamin D, which binds to vitamin D receptors in various body tissues and has its biological effects.
- Factors affecting the synthesis of vitamin D from the sun
The effectiveness of the synthesis of vitamin D under the influence of sunlight depends on many factors:
- Top of year: In the winter months, especially in the northern latitudes, the angle of decline in sunlight becomes more acute, which leads to a smaller amount of UVB rays reaching the surface of the Earth. This significantly reduces the production of vitamin D.
- Times of Day: The sun should be high enough in the sky so that UVB rays can penetrate through the atmosphere. The most effective time for the production of vitamin D is from 10:00 to 15:00, when the sun is at a zenith.
- Latitude: The farther from the equator, the less UVB-rays reaches the surface of the earth, especially in the winter months. People living in the northern latitudes may need to spend more time in the sun or take vitamin D.
- Cloud and air pollution: Clouds and air pollution are blocking UVB ray, reducing the production of vitamin D.
- Type of skin: People with darker skin have more melanin, a pigment that absorbs UVB rays. This means that people with dark skin need to spend more time in the sun to develop the same amount of vitamin D as people with light skin.
- Use of sunscreen: The sunscreen blocks UVB ray, reducing the production of vitamin D. Although it is important to protect the skin from the harmful effects of the sun, sufficient exposure to the sun without sunscreen for a short time can help in the production of vitamin D.
- Age: With age, the ability of the skin to produce vitamin D is reduced.
- Safe stay in the sun for pregnant women
For pregnant women, it is important to balance the need for vitamin D and risks associated with excessive sun stay. The following is recommended:
- Spend in the sun 10-15 minutes a day: In the period from 10:00 to 15:00, when the sun is most actively, 10-15 minutes of stay in the sun without sunscreen are enough to stimulate the production of vitamin D. Start with a short time and gradually increase it if your skin tolerates the sun well.
- Protect your face and eyes: Use a hat and sunglasses to protect your face and eyes from the harmful effects of the sun.
- Apply sunscreen after sufficient stay in the sun: After 10-15 minutes of stay in the sun, apply SPF 30 or higher sunscreen to protect the skin from sunburn and reduce the risk of skin cancer.
- Avoid sunburn: Sun burns are harmful to the skin and increase the risk of skin cancer. Always protect the skin if you plan to be in the sun for a long time.
- Consider your skin type: People with darker skin may need to spend more time in the sun to develop a sufficient amount of vitamin D.
- Consult a doctor: Talk to your doctor about how much time you should spend in the sun in order to get enough vitamin D, given your skin type, location and other factors.
B. Food sources
- List of products rich in vitamin D
Although sunlight is the main source of vitamin D, some foods also contain it, although in smaller quantities. The inclusion of these products in your diet can help increase vitamin D consumption. The main food sources of vitamin D:
- Fat fish: Salmon, tuna, mackerel and herring are excellent sources of vitamin D. Salmon, especially wild, contains the largest amount of vitamin D.
- Fish oil: Fish oil, such as fish oil from the liver liver, is a rich source of vitamin D.
- Egg yolks: Egg yolks contain vitamin D, but the amount of vitamin D depends on the diet of chicken. Eggs from chickens grown in the sun or received food, enriched with vitamin D, contain more vitamin D.
- Enriched products: Many products, such as milk, yogurt, juices and flakes for breakfast, are enriched with vitamin D. Be sure to check the labels to see how much vitamin D is contained in these products.
- Mushrooms: Some mushrooms, especially exposed to ultraviolet light, contain vitamin D.
- Recommendations to include these products in the diet of a pregnant woman
For pregnant women, it is important to include in their diet products rich in vitamin D. Here are some tips:
- Eat fatty fish 2-3 times a week: Include salmon, tuna, mackerel or herring in your diet. Make sure the fish is well cooked to avoid the risk of infection with bacteria.
- Add egg yolks to your diet: Use eggs from chickens grown in the sun or received food enriched with vitamin D.
- Drink enriched milk or juice: Choose milk or juice enriched with vitamin D. Check the labels to see how much vitamin D is contained in these products.
- Eat enriched breakfast flakes: Include enriched breakfast flakes in your diet. Check the labels to see how much vitamin D is contained in these products.
- Prepare with mushrooms that are exposed to ultraviolet light: Add mushrooms exposed to ultraviolet light to your dishes.
- Consider the possibility of eating fish oil: Consult with your doctor before eating fish oil, as it also contains vitamin A, which in large quantities can be harmful during pregnancy.
C. Vitamin D additives
- Types of vitamin D (D2 and D3) additives
When obtaining a sufficient amount of vitamin D only due to sunlight and diet is difficult, vitamin D additives can be necessary, especially during pregnancy. There are two main forms of vitamin D, available in additions: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).
-
Vitamin D2 (ergocalciferol): Vitamin D2 is obtained from plants, mainly from mushrooms irradiated with ultraviolet light. It is less effective than vitamin D3 in increasing the level of vitamin D in the blood.
-
Vitamin D3 (cholecalciferol): Vitamin D3 is produced in human skin under the influence of sunlight and is found in animal products. It is usually more effective than vitamin D2 in increasing and maintaining the level of vitamin D in the blood, since it is more effectively metabolized into the active form of vitamin D in the body. Vitamin D3 is preferable for pregnant women.
- Recommendations for the dosage of vitamin D additives for pregnant women
The recommended daily dose of vitamin D for pregnant women is 600 IU (international units) per day. However, for many pregnant women, especially those who have a deficiency of vitamin D or risk factors for its development, a higher dose may require. Many experts recommend up to 2000-4000 IU per day, but pregnant women should talk with their attending physicians to determine the correct dosage for their specific needs.
- When you need to take vitamin D additives
Reception of vitamin D additives can be necessary in various situations during pregnancy:
- Vitamin D deficiency: If a blood test shows a low vitamin D level (less than 30 ng/ml), it is necessary to take additives to replenish the deficiency.
- Limited Sun stay: Pregnant women who spend little time in the sun because of their lifestyle, type of skin or climate, should take additives to provide a sufficient level of vitamin D.
- Certain dietary restrictions: Vegetarians or vegans may not receive enough vitamin D only from the diet and may need in addition.
- Risk factors of deficiency: Pregnant women with risk factors for vitamin D deficiency, such as obesity, dark skin or certain diseases, must take additives.
- Vitamin D Safety Safety during pregnancy
Vitamin D additives are usually considered safe during pregnancy, if they are taken in recommended doses. It is very important to adhere to the recommended dose and not exceed it, since taking an excessive amount of vitamin D can lead to toxicity. Symptoms of vitamin D toxicity may include nausea, vomiting, weakness and kidney problems. Before taking any additives, pregnant women should consult their doctor to make sure that they are safe for them and their child.
D. Combination of vitamin D sources
The best approach to maintaining an adequate level of vitamin D during pregnancy is a combination of various sources:
- Sun stay: Spend in the sun from 10 to 15 minutes a day, especially from 10:00 to 15:00, when the sun is most active.
- Nutrition: Include products rich in vitamin D in your diet, such as oily fish, egg yolks and enriched products.
- Supplements: If you do not get enough vitamin D only due to sunlight and diet, take vitamin D additives on the recommendation of your doctor.
- Regular monitoring: Spended the level of vitamin D in the blood regularly to make sure that it is in the optimal range.
Combining these sources, pregnant women can provide an adequate level of vitamin D to maintain their health and health.
III. Determination of vitamin D level
A. Blood test for vitamin D (25-hydroxyvitamin d)
The most accurate way to determine the level of vitamin D in the body is a blood test that measures the level of 25-hydroxyvitamin D [25(OH)D]also known as calciol. This is the main form of vitamin D, circulating in the blood, and it is the best indicator of the general status of vitamin D.
A blood test for vitamin D is a simple and routine test that can be carried out in the doctor’s office or in the laboratory. Blood is usually taken from the vein on the arm. Analysis does not require special preparation, although some doctors may recommend refraining from taking certain additives before analysis.
B. The optimal level of vitamin D during pregnancy
The optimal level of vitamin D during pregnancy is from 30 to 50 ng/ml (75-125 nmol/l). Levels below 30 ng/ml are considered insufficient, and levels below 20 ng/ml indicate a deficiency of vitamin D.
- Deficiency: Less than 20 ng/ml (50 nmol/l)
- Failure: 20-29 ng/ml (50-72.5 nmol/l)
- Enough: 30-50 ng/ml (75-125 nmol/l)
- High: More than 50 ng/ml (125 nmol/l)
For pregnant women, it is important to maintain the level of vitamin D in a sufficient range in order to maintain their health and health. Depending on the results of blood tests, your doctor may need to adjust the dosage of vitamin D additives or offer to change the lifestyle.
C. Interpretation of the results of the analysis and action in case of deficiency
After you get the results of a blood test for vitamin D, it is important to interpret them correctly and take appropriate measures, especially if you are pregnant.
-
Low level of vitamin D (deficiency): If your vitamin D level is below 20 ng/ml, you have a deficiency of vitamin D. Your doctor will probably recommend taking vitamin D additives, often in a higher dose to quickly increase the level. Your doctor may also recommend you to spend more time in the sun and consume products rich in vitamin D.
-
Insufficient vitamin D: If your vitamin D level is in the range of 20-29 ng/ml, you have vitamin D insufficiency. Your doctor may recommend you take vitamin D additives in a lower dose to increase vitamin D levels to the optimal range.
-
Sufficient level of vitamin D: If your vitamin D level is in the range of 30-50 ng/ml, your vitamin D level is sufficient. However, it is important to continue to maintain this level, regularly in the sun, using products rich in vitamin D, and taking additives, if necessary.
-
High level of vitamin D: If your level of vitamin D is above 50 ng/ml, you have too high the level of vitamin D. Your doctor will probably recommend that you stop taking vitamin D additives and regularly check the level of vitamin D to make sure that it does not remain too high.
It is important to follow the advice of your doctor to maintain an adequate level of vitamin D during pregnancy. Regular blood tests and adjusting the dosage of vitamin D additives as necessary can help ensure your health and health of your child.
IV. Risk factors for vitamin D during pregnancy
Several factors can increase the risk of vitamin D deficiency during pregnancy. It is important to know about these risk factors and take measures to maintain a sufficient level of vitamin D.
A. Geographical location and season
The geographical position and season play an important role in the development of vitamin D. People living away from the equator, especially in the northern latitudes, have a higher risk of vitamin D deficiency, especially in the winter months, when there are fewer sunlight. The angle of sunlight and UVB-radiation intensity in the winter months are insufficient for the effective synthesis of vitamin D in the skin.
B. Type of skin
The type of skin affects the production of vitamin D. In people with darker skin there is more melanin, which acts as a natural sunscreen and reduces the production of vitamin D in the skin. People with darker skin need to spend more time in the sun to develop the same amount of vitamin D as people with light skin.
C. The diet
The diet plays a role in the status of vitamin D. People who do not use enough products rich in vitamin D, have an increased risk of vitamin D. vegetarians and vegan, which do not use animal products, can also have an increased risk of vitamin D deficiency if they do not consume enriched products or additives.
D. Life
Life lifestyle factors can affect the status of vitamin D. People who spend little time in the open air or wear protective clothing or sunscreen, when they are on the street, have an increased risk of vitamin D. Working, household or life in the area with a high level of air pollution, which blocks sunlight, can also contribute to vitamin D.
E. Excess weight and obesity
Excess weight and obesity are associated with a lower level of vitamin D. Vitamin D is a fat -soluble vitamin that can be absorbed by adipose tissue, which reduces its accessibility in the blood. Pregnant women with overweight or obesity may have an increased risk of vitamin D deficiency, and they may require higher doses of additives to maintain an adequate level.
F. Some diseases and medicines
Some diseases and drugs can affect vitamin D metabolism and increase the risk of deficiency. Diseases, such as Crohn’s disease, celiac disease and cystic fibrosis, can violate the absorption of vitamin D in the intestines. Medicines, such as glucocorticoids and anticonvulsants, can also affect the metabolism of vitamin D.
G. Age and number of pregnancies
With age, the ability of the skin to produce vitamin D is reduced. Older people and pregnant women of older have an increased risk of vitamin D deficiency. In addition, women who have been pregnant many times can exhaust their vitamin D reserves and have an increased risk of vitamin D deficiency during subsequent pregnancies.
V. Symptoms and signs of vitamin D deficiency during pregnancy
Vitamin D deficiency during pregnancy can be manifested by various symptoms and signs. These symptoms can be non -specific and they can easily be confused with other common pregnancy problems. Therefore, it is important to know about the potential signs of vitamin D deficiency and report any problems to your doctor.
A. General symptoms
General symptoms of vitamin D deficiency during pregnancy may include:
- Fatigue and weakness: A feeling of fatigue and weakness even after rest.
- Bone pain and muscles: Aching pain or soreness in bones, joints or muscles.
- Muscle cramps or spasms: Involuntary muscle contractions or cramps.
- Weakness: Weakness that makes it difficult to perform everyday actions.
- Mood swings: A feeling of sadness, irritability or anxiety.
- Reduced immunity: Frequent infections or slow healing of wounds.
B. Specific symptoms associated with pregnancy
In addition to general symptoms, a deficiency of vitamin D during pregnancy can also cause certain symptoms associated with pregnancy:
- Precomports: High blood pressure and the presence of protein in the urine, which can lead to serious complications for both the mother and the child.
- Gestational diabetes: The development of diabetes during pregnancy.
- Premature birth: Childbirth up to 37 weeks of pregnancy.
- Low birth weight: A child is born with a weight of less than 5.5 pounds.
- Increased risk of cesarean section: The need for surgical delivery due to problems associated with vitamin D. deficiency.
It is important to note that these symptoms can be caused by other conditions, and to determine the cause of your symptoms and obtain the appropriate treatment, it is necessary to consult a doctor.
VI. Vitamin D and child’s health
Vitamin D plays a decisive role in the health and development of the child, starting with pregnancy and continuing in infancy and childhood. Adequate levels of vitamin D during pregnancy are important for optimal health and development of the fetus, and vitamin D additives may be required for babies to maintain a sufficient level after birth.
A. The influence of vitamin D on the development of bones and teeth
Vitamin D is necessary for the development of bones and teeth in a child. It helps to absorb calcium and phosphorus, which are important minerals for the formation of strong bones and teeth. During pregnancy, vitamin D deficiency can lead to rickets in newborns, a state characterized by soft and weak bones. Children with rickets may have delays in the development of motor skills, curvature of the legs and other skeletal deformations.
B. Vitamin D and the immune system of the child
Vitamin D plays a role in the development of the immune system of the child. It helps to regulate the immune response and protects against infections. Vitamin D deficiency during pregnancy can increase the risk of infections in a child and can jeopardize the development of his immune system.
C. Vitamin D and prevention of diseases in a child
Studies have shown that vitamin D can play a role in the prevention of certain diseases in children. Vitamin D deficiency is associated with an increased risk of developing autoimmune diseases, such as type 1 diabetes, asthma and allergies. The adequate level of vitamin D during pregnancy and in early childhood can help reduce the risk of these diseases.
D. Vitamin D and child brain development
The data that appears indicate that vitamin D can play a role in the development of the child’s brain. Vitamin D-receptors are present in the brain, and vitamin D is involved in neuroprotection, neurogenesis and synaptic function. Vitamin D deficiency during pregnancy can affect the development of the child’s brain and can be associated with cognitive disorders and disorders of nervous development.
VII. Vitamin D and pregnancy complications
Vitamin D deficiency during pregnancy is associated with an increased risk of various complications of pregnancy. The adequate level of vitamin D is important for the optimal health of the mother and child and can help reduce the risk of these complications.
A. Preclude
Preeclampsia is a serious complication of pregnancy, characterized by high blood pressure and the presence of protein in the urine. This can lead to serious problems for both the mother and the child, including premature birth, placental detachment and maternal incidence and mortality. Several studies have shown that vitamin D deficiency during pregnancy is associated with an increased risk of preeclampsia.
B. Gestational diabetes
Gestational diabetes is a type of diabetes that develops during pregnancy. It can increase the risk of complications for both the mother and the child, including a large size at birth (macrosomy), dystice of the shoulders and neonatal hypoglycemia. Vitamin D deficiency during pregnancy is associated with an increased risk of gestational diabetes.
C. Premature birth
Premature birth is childbirth that occurs before 37 weeks of pregnancy. Premature birth is associated with an increased risk of health problems in a child, including a respiratory distress syndrome, cerebral paralysis and developmental delays. Vitamin D deficiency during pregnancy is associated with an increased risk of premature birth.
D. Low birth weight
Low weight at birth is the birth of a child with a weight of less than 5.5 pounds. Low weight at birth is associated with an increased risk of health problems in a child, including a respiratory distress syndrome, infection and death. The deficiency of vitamin D during pregnancy is associated with an increased risk of low weight at birth.
VIII. The role of vitamin D after childbirth
Vitamin D continues to play an important role after childbirth, especially for nursing mothers and their babies. The adequate level of vitamin D is necessary to maintain the health of the mother and ensure the optimal development and health of the child.
A. The importance of vitamin D for nursing mothers
Vitamin D is important for nursing mothers, as it helps to maintain bone health and immune function. Breastfeeding increases the need for the mother in vitamin D, since vitamin D is transmitted to the baby through breast milk. Nursing mothers with vitamin D deficiency may need to take additives to maintain a sufficient level of vitamin D.
B. The effect of vitamin D on breast milk
Vitamin D in breast milk is important for the health of the baby. Breast milk is the best source of nutrition for infants, but it may not contain vitamin D, especially if the mother has a deficiency of vitamin D. Vitamin D additives are important for pregnant and nursing women to provide a sufficient level of vitamin D in breast milk.
C. Vitamin D additives for babies
The American Academy of Pediatrics recommends that all those who are on breast feeding infants receive vitamin D additives from birth until they receive enough vitamin D from other sources, such as enriched products. The recommended dose of vitamin D for babies is 400 IU per day. Vitamin D additives are important for babies on breast feeding, since breast milk may not provide them with a sufficient amount of vitamin D.
IX. Myths and errors about vitamin D and pregnancy
There are several myths and errors associated with vitamin D and pregnancy. It is important to know these myths and receive information from reliable sources.
A. Myths about sunlight
- Myth: You need to spend a lot of time in the sun to get enough vitamin D.
- Reality: Conducting in the sun from 10 to 15 minutes a day, especially from 10:00 to 15:00, can help you develop a sufficient amount of vitamin D.
- Myth: You do not need to worry about vitamin D if you live in a sunny climate.
