Vitamins for pregnant women: iodine for the health of the thyroid gland. Part 1. Fundamentals and importance of iodine

1.1. The role of iodine in the human body

Iodine, a trace element with atomic number 53, plays a critical role in maintaining the health and functioning of the human body. Its main and most well -known function is participation in the synthesis of thyroid hormones: thyroxine (T4) and triiodothyronine (T3). These hormones, in turn, regulate many vital processes, including:

  • Metabolism: The hormones of the thyroid gland have a direct effect on the rate of metabolism, determining how quickly the body converts food into energy. They regulate the absorption of oxygen with cells, participate in thermogenesis (heat production) and control calorie consumption. The lack of iodine and, as a result, hormones of the thyroid gland, leads to a slowdown in metabolism, which manifests itself in fatigue, increase in weight, constipation and other symptoms.

  • Growth and development: The thyroid hormones are necessary for normal growth and development, especially in childhood and adolescence. They affect the formation of bone tissue, the development of the brain and nervous system, as well as the differentiation of cells. The disadvantage of iodine in childhood can lead to a delay in growth, mental retardation and other serious health problems.

  • Nervous system functions: The thyroid hormones play an important role in the functioning of the nervous system, affecting the transmission of nerve impulses, cognitive functions and emotional state. The lack of iodine can cause irritability, anxiety, depression and memory worsening.

  • Reproductive function: Thyroid hormones are necessary for normal reproductive function in both women and men. In women, they affect the menstrual cycle, ovulation and maintenance of pregnancy. In men, they affect spermatogenesis and potency. The lack of iodine can lead to infertility, miscarriages and other problems with reproductive health.

  • Body temperature regulation: Thyroid hormones help maintain normal body temperature, affecting thermogenesis. The lack of iodine can lead to a constant sensation of cold, even in a warm room.

1.2. Why iodine is especially important during pregnancy

During pregnancy, the need for iodine increases significantly. This is due to several factors:

  • The mother’s increased need: During pregnancy, the mother’s body works with increased load, providing nutrition and development of the fetus. This requires an increase in the synthesis of thyroid hormones, which, in turn, increases the need for iodine.

  • The fetal iodine is transmitted: The fetus cannot independently synthesize thyroid hormones to a certain stage of development. Therefore, it completely depends on the flow of iodine from the mother. The iodine is transported through the placenta and is used by the fruit for the synthesis of the thyroid hormones necessary for the normal development of the brain and nervous system.

  • Increase in iodine excretion: During pregnancy, the excretion of iodine in urine increases, which also helps to increase the need for this trace element.

During pregnancy, iodine deficiency can have serious consequences for the health of both the mother and the child.

1.3. The consequences of iodine deficiency for mother and child

Iodine deficiency during pregnancy can lead to the following consequences:

  • For mother:

    • Hypothyroidism: The disadvantage of iodine can cause hypothyroidism – a condition in which the thyroid gland does not produce enough hormones. Hypothyroidism can manifest itself in fatigue, increase in weight, constipation, dry skin, hair loss, memory worsening and concentration.
    • Goiter: In an attempt to compensate for the lack of iodine, the thyroid gland can increase in the amount, forming a goiter.
    • Increased risk of pregnancy complications: During pregnancy, hypothyroidism can increase the risk of miscarriages, premature birth, gestational diabetes and preeclampsia.
    • Postpartum thyroiditis: Iodine deficiency can contribute to the development of postpartum thyroiditis – an autoimmune thyroid disease, which can occur after childbirth.

  • For a child:

    • Congenital hypothyroidism: The lack of iodine in the mother can lead to congenital hypothyroidism in a child. Congenital hypothyroidism can cause growth and development, mental retardation and other serious health problems.
    • Mental development delay: Even the moderate deficiency of iodine during pregnancy can negatively affect the mental development of the child, reducing his IQ and academic performance.
    • Disorders of the development of the nervous system: Iodine deficiency can cause disorders of the development of the nervous system, leading to problems with coordination of movements, speech and training.
    • Increased risk of children’s mortality: A severe iodine deficiency can increase the risk of child mortality.

1.4. Recommended iodine consumption standards during pregnancy

The World Health Organization (WHO) recommends pregnant and nursing women to consume at least 250 μg of iodine per day. This is significantly higher than the recommended norm for adult non -pregnant women (150 mcg per day). Providing sufficient iodine consumption during pregnancy is an important task for maintaining the health of the mother and the child.

Vitamins for pregnant women: iodine for the health of the thyroid gland. Part 2. Sources of iodine

2.1. Food sources of iodine

Although iodine is present in the environment, its content in soil and water can vary significantly depending on the geographical region. Therefore, not all foods are reliable sources of iodine. Nevertheless, there are certain products that contain a sufficient amount of iodine and can help satisfy the needs of the body, especially during pregnancy.

  • Sea fish and seafood: Sea fish, such as cod, salmon, tuna and shrimp, is an excellent source of iodine. The content of iodine in fish depends on its type and habitat. Other seafood, such as seaweed (laminaria, spirulina) also contain a very high amount of iodine. However, you should be careful with the consumption of seaweed, as they can contain an excess of iodine, which can also be harmful to health.

  • Iodized salt: Iodated salt is ordinary sodium salt, to which potassium iodat or iodide potassium is added. Salt iodine is an effective and inexpensive way to prevent iodine deficiency on the scale of the entire population. The use of iodized salt in cooking is one of the simplest ways to increase iodine consumption. It is important to remember that iodine can disappear when heated, so iodized salt is recommended to add to dishes at the end of cooking.

  • Dairy products: Milk, yogurt and cheese contain a certain amount of iodine, as cows get iodine from food and water. However, the content of iodine in dairy products can vary depending on the region and the diet of cows.

  • Eggs: Eggs, especially the yolk, contain a small amount of iodine. The iodine content in eggs can also vary depending on the diet of chickens.

  • Plants grown on soil rich in iodine: Some fruits and vegetables grown on a soil rich in iodine may contain a certain amount of iodine. However, the content of iodine in plant products greatly depends on the geographical region and growing conditions.

2.2. Iodized products and their role in the prevention of iodine deficiency

In addition to iodized salt, there are other iodized products that can help increase iodine consumption. These include:

  • Iodized bread: In some countries, iodized bread is produced, which contains potassium iodate or potassium iodide.

  • Iodized milk: In some regions, milk is enriched with iodine.

  • Iodized water: In areas with a low iodine content in water, drinking water can be iodized.

Food iodization is an effective way to prevent iodine deficiency on the scale of the entire population. However, it is important to ensure not to consume an excess of iodine, as it can also be harmful to health.

2.3. Biologically active additives (dietary supplements) with iodine for pregnant women

During pregnancy and breastfeeding, the need for iodine increases significantly, and it is not always possible to satisfy this need only at the expense of the diet. In such cases, it is recommended to take biologically active additives (dietary supplements) with iodine.

  • The composition of dietary supplements with iodine: A dietary supplement with iodine usually contain potassium iodide or potassium iodate as a source of iodine. They can be presented in the form of tablets, capsules or drops.

  • Dosage of iodine in dietary supplements: It is important to choose a dietary supplement with iodine that contain a dose recommended by a doctor. The usually recommended dose of iodine for pregnant women and lactating women is 150-250 μg per day.

  • Advantages and disadvantages of dietary supplements with iodine: A dietary supplement with iodine is a convenient and effective way to provide sufficient iodine consumption, especially during pregnancy. However, before taking the dietary supplement with iodine, it is necessary to consult a doctor in order to make sure that there are no contraindications and choose the optimal dose.

  • How to choose the right dietary supplement with iodine: When choosing dietary supplements with iodine, attention should be paid to the following factors:

    • Manufacturer: Choose a dietary supplement from well -known and reliable manufacturers that guarantee the quality and safety of your products.
    • Composition: Make sure that dietary supplement contains potassium iodide or potassium iodate as an iodine source.
    • Dosage: Choose dietary supplements with a dosage recommended by a doctor.
    • Certification: Make sure that the dietary supplement is certified and meets the safety requirements.
    • Reviews: Read the reviews of other consumers about dietary supplements to learn about their experience of using the product.

2.4. Recommendations for the use of iodine from various sources

To ensure sufficient iodine consumption during pregnancy, it is recommended:

  • Use iodized salt in cooking.
  • Include sea fish and seafood in the diet 2-3 times a week.
  • Eat dairy products and eggs.
  • Take a dietary supplement with iodine on the recommendation of a doctor.

It is important to remember that excess iodine consumption can also be harmful to health. Therefore, it is necessary to comply with the recommended norms of iodine consumption and not exceed them without consulting a doctor.

Vitamins for pregnant women: iodine for the health of the thyroid gland. Part 3. Diagnosis of deficiency and excess iodine

3.1. Methods for diagnosing iodine deficiency

There are several methods for diagnosing iodine deficiency, which allow you to assess the level of iodine in the body and identify disorders in the thyroid gland.

  • Urine analysis for iodine: This analysis is the most common method of evaluating iodine consumption on a population. It measures the concentration of iodine in the urine, which reflects the amount of iodine consumed in the last 24 hours. The level of iodine in the urine below 100 μg/l indicates a deficiency of iodine.

  • Blood test for thyroid hormones (TS, T4, T3): This analysis allows you to evaluate the function of the thyroid gland and identify hypothyroidism. With iodine deficiency, the thyroid gland may not produce enough hormones, which leads to an increase in the level of thyroid hormone (TSH) in the blood. TSH stimulates the thyroid gland to the production of hormones, and its increase indicates that the thyroid gland works with increased load.

  • Ultrasound examination (ultrasound) of the thyroid gland: Ultrasound of the thyroid gland allows you to evaluate its size and structure. With iodine deficiency, the thyroid gland can increase in size, forming goiter.

  • TireTropin-Rilizing Gormon (Square) test (Square): This test is used to diagnose hidden hypothyroidism. The patient is introduced by TRG, which stimulates the production of TSH. In patients with hypothyroidism, the TSH level after the introduction of TRG increases significantly more than in healthy people.

3.2. Symptoms of iodine deficiency and excess

The deficiency and excess iodine can be manifested by various symptoms that can be both general and specific.

  • Symptoms of iodine deficiency:

    • Fatigue, weakness: Iodine deficiency can lead to a slowdown in metabolism, which causes fatigue and weakness.
    • Weight gain: Iodine deficiency can lead to a slowdown in metabolism and weight gain.
    • Constipation: Iodine deficiency can lead to a slowdown in intestinal motility and constipation.
    • Dry skin: Iodine deficiency can lead to a decrease in the production of skin fat and dry skin.
    • Hair loss: Iodine deficiency can lead to a violation of hair growth and its loss.
    • Memory deterioration and concentration: Iodine deficiency can negatively affect cognitive functions, leading to a deterioration in memory and concentration.
    • Sensation of cold: Iodine deficiency can lead to a violation of thermogenesis and a constant sensation of cold.
    • Goiter: In an attempt to compensate for the lack of iodine, the thyroid gland can increase in the amount, forming a goiter.

  • Symptoms of excess iodine:

    • Hypertreenineosis: Excess iodine can cause hyperthyroidism – a condition in which the thyroid gland produces excess hormones.
    • Goiter: Excess iodine can cause an increase in the thyroid gland (goiter).
    • Iodism: Yodism is a state that occurs with an excessive intake of iodine into the body. It manifests itself in a metallic taste in the mouth, increased salivation, burning in the throat, runny nose, lacrimation and skin rash.
    • Autoimmune thyroiditis: Excess iodine can provoke the development of autoimmune thyroiditis in people with a predisposition to this disease.

3.3. Who needs an examination for iodine deficiency during pregnancy

An examination for iodine deficiency is recommended to all pregnant women, especially those who are at risk:

  • Residents of regions with iodine deficiency: In regions with a low iodine content in the soil and water, the risk of iodine deficiency is higher.
  • Women with a history of thyroid gland: Thyroid diseases, such as hypothyroidism or autoimmune thyroiditis, can increase the risk of iodine deficiency.
  • Women who do not use iodized salt: The use of iodized salt is an important way to prevent iodine deficiency.
  • Vegetarians and vegans: A plant diet can be poor iodine, since many plant products do not contain enough iodine.
  • Women smoking during pregnancy: Smoking can negatively affect the function of the thyroid gland and increase the risk of iodine deficiency.

3.4. Interpretation of test results and consultation with a doctor

The interpretation of the results of iodine tests and thyroid hormones should be carried out by a doctor. Based on the results of the tests and the anamnesis, the doctor may establish a diagnosis and prescribe the appropriate treatment.

If iodine deficiency is detected, the doctor can recommend:

  • Increased iodine consumption with food: The inclusion of sea fish, seafood, dairy products and eggs in the diet.
  • Using iodized salt in cooking.
  • Reception of dietary supplements with iodine.

If an excess of iodine is detected, a doctor can recommend:

  • Limiting iodine consumption with food: Avoid the use of seaweed and other products containing a high amount of iodine.
  • Continuation of dietary supplements with iodine.
  • The appointment of drugs that reduce the function of the thyroid gland (in the case of hyperthyroidism).

It is important to remember that self -medication is unacceptable. For any health problems, you must consult a doctor to establish a diagnosis and prescribe adequate treatment.

  • Ensuring the availability of iodized products: State health authorities should ensure the availability of iodized salt and other iodized products for all segments of the population.

4.2. Individual measures to prevent iodine deficiency

In addition to measures to prevent iodine deficiency at the state level, each person can take individual measures to ensure sufficient iodine consumption.

  • Using iodized salt in cooking: Use iodized salt instead of ordinary table salt in cooking. Keep iodized salt in a sealed container in a dark and cool place to prevent iodine loss.

  • The inclusion in the diet of sea fish and seafood 2-3 times a week: Sea fish and seafood are excellent sources of iodine.

  • The use of dairy products and eggs: Dairy products and eggs contain a certain amount of iodine.

  • Reception of dietary supplements with iodine on the recommendation of a doctor: If you are not sure that you get enough iodine with food, consult your doctor about the need to receive dietary supplements with iodine.

4.3. Prevention of excess iodine

Excess iodine can also be harmful to health, so it is important to observe moderation in iodine consumption.

  • Restriction of consumption of seaweed: Sea algae contain a very high amount of iodine, so they should be consumed in moderate quantities.

  • Avoid taking dietary supplement with iodine without consulting a doctor: Reception of dietary supplements with iodine must be agreed with a doctor to avoid an overdose.

  • Inform the doctor about taking iodine -containing drugs: If you take any drugs containing iodine, inform your doctor about it.

4.4. The role of nutrition and lifestyle in maintaining the health of the thyroid gland

In addition to sufficient iodine consumption, other nutrition and lifestyle factors affect the health of the thyroid gland.

  • Balanced nutrition: A balanced diet, rich in vitamins and minerals, is necessary to maintain the health of the thyroid gland.

  • Sufficient consumption of selenium: Selenium is an important trace element that is involved in the synthesis of thyroid hormones and protects it from oxidative stress. Good sources of Selena are Brazilian nuts, tuna, sardines and eggs.

  • Restriction of intake consumption: Coobogenic substances are substances that can prevent the absorption of iodine with a thyroid gland and cause goiter. They are found in some vegetables, such as cabbage, broccoli and turnip. Moderate consumption of these vegetables is not dangerous, but excessive use can be harmful, especially with iodine deficiency.

  • Refusal of smoking: Smoking negatively affects the function of the thyroid gland and increases the risk of thyroid diseases.

  • Stress management: Stress can negatively affect the function of the thyroid gland. It is important to learn how to cope with stress using relaxation techniques, yoga or other methods.

  • Regular physical exercises: Regular physical exercises help maintain healthy metabolism and thyroid function.

5.1. Alternative approaches to maintaining thyroid health (herbal medicine, homeopathy)

Some people turn to alternative approaches, such as herbal medicine and homeopathy, to maintain the health of the thyroid gland. However, it is important to remember that the effectiveness of these methods is not scientifically proven.

  • Phytotherapy: Phytotherapy is the use of medicinal plants to treat diseases. Some plants, such as Fucus Bubble (Fucus Vesiculosus), contain iodine and can be used to maintain thyroid function. However, you should be careful when using plant drugs, as they can contain high doses of iodine and cause side effects.

  • Homeopathy: Homeopathy is a treatment system based on the principle of “like this.” Homeopathic preparations are made by repeated dilution of the initial substance, as a result of which in the final product there is very little or no initial substance remains at all. The effectiveness of homeopathy has not been proved scientifically, and homeopathic drugs should not be used as a replacement for traditional medical care.

5.2. Myths about iodine and thyroid gland

There are many myths about iodine and thyroid gland that can be misleading and leading to improper treatment.

  • Myth: iodine is dangerous for people with autoimmune thyroiditis. In fact, moderate iodine consumption is not dangerous for people with autoimmune thyroiditis. However, excess iodine consumption can provoke an exacerbation of the disease.

  • Myth: seaweed – the best source of iodine. Sea algae contain a very high amount of iodine, but their use in large quantities can lead to an overdose of iodine.

  • Myth: If I have goiter, I need more iodine. The goiter can be caused by both a shortage and an excess of iodine. Therefore, if the goiter is detected, you must consult a doctor to establish the cause and prescribe the appropriate treatment.

  • Myth: iodized salt is harmful to health. Salt iodization is a safe and effective way to prevent iodine deficiency.

5.3. The importance of critical thinking and consultation with a doctor

When finding information about iodine and thyroid gland, it is important to show critical thinking and check the reliability of information from various sources. Do not trust unverified information and engage in self -medication.

For any health problems, you must consult a doctor to establish a diagnosis and prescribe adequate treatment. The doctor will conduct the necessary examinations, evaluate your condition and give recommendations on the prevention and treatment of thyroid diseases.

5.4. Modern research on iodine and pregnancy

Modern studies continue to confirm the importance of sufficient iodine consumption during pregnancy for the health of the mother and child. Studies show that iodine deficiency during pregnancy can negatively affect the cognitive development of the child, reduce his IQ and academic performance.

New studies also study the effect of excess iodine consumption during pregnancy on the health of the thyroid gland of the mother and child. These studies show that an excess of iodine can lead to the development of hyperthyroidism and autoimmune thyroiditis.

Therefore, it is important to observe moderation in iodine consumption and follow the doctor’s recommendations.
