A woman’s body undergoes multiple changes during pregnancy. One such effect is witnessed in the functioning of the thyroid gland, leading to many complications due to hyperthyroidism. It is a condition where a woman’s thyroid gland produces too much thyroid hormone during pregnancy. Hyperthyroidism in pregnancy can have significant effects on both the mother and the developing foetus.
The thyroid gland is a butterfly-shaped gland in the neck that generates hormones that regulate the body's metabolism. Hyperthyroidism during pregnancy can cause severe symptoms such as weight loss and increased heart rate. If left untreated, it can lead to serious complications such as preterm birth, low birth weight, and preeclampsia.
When one’s thyroid gland produces excessive thyroid hormone, leading to an overactive metabolism, it is known as hyperthyroidism. While hyperthyroidism can occur in anyone, it is a particular concern during pregnancy and can lead to serious health complications for both the mother and the baby.
During pregnancy, women typically produce double the amount of thyroid hormones compared to before they were pregnant. These hormones, called triiodothyronine (T3) and thyroxine (T4), are crucial for both the mother's body and the development of the foetus. However, producing too much thyroid hormone during pregnancy can be a concern because it may affect the baby's development and increase the risk of preterm birth.
When it comes to hyperthyroidism in pregnancy, there can be several reasons that can lead to this condition. It is essential to identify the right cause of hyperthyroidism for doctors to ensure the right course of action for the treatment. Some of the most common causes of hyperthyroidism in pregnant women include:
These are some of the most highlighted causes of hyperthyroidism in pregnancy. It is crucial for pregnant women to get dedicated consultations and understand the cause of the condition. This helps in getting timely treatment and preventing the chances of severe complications.
While most hyperthyroidism in pregnancy symptoms are similar to the normal conditions in pregnancy. Thus, it can sometimes be difficult to identify them right away. However, prolonged symptoms or an extreme impact on health due to these issues must be brought to your doctor’s attention. The following are the most common symptoms of hyperthyroidism in pregnancy:
Hyperthyroidism is directly associated with an active metabolism, and thus, watching one’s weight changes is crucial. Women who do not gain any weight during pregnancy can also indicate the condition of hyperthyroidism.
The diagnosis of hyperthyroidism in pregnancy involves a combination of physical examination, blood tests, and thyroid function tests. The doctor will first evaluate the woman's symptoms and medical history to determine if hyperthyroidism is likely.
There are multiple treatments to bring down the steep increase in the thyroid hormone of women during pregnancy. The hyperthyroidism treatment in pregnancy depends on the condition's severity and the pregnancy's trimester. The two primary treatment options are medication and surgery.
However, the course of treatment one opts for must be carefully administered to not cause any complications during childbirth. Below are the most sought-after treatments for hyperthyroidism in pregnancy:
Hyperthyroidism in pregnancy cannot be completely prevented, but some steps can help reduce the risk and severity of the condition.
It's important to consult a doctor if you experience symptoms of hyperthyroidism during pregnancy such as rapid heartbeat, weight loss, anxiety, or difficulty sleeping.
Additionally, if you have a history of thyroid problems or are taking medication for thyroid disorders, you should discuss this with your doctor and have regular thyroid hormone level checks during pregnancy. Prompt treatment and monitoring can help reduce the risk of complications for both the mother and baby.
Hyperthyroidism in pregnancy is a serious condition that can significantly impact the health of both mother and baby. It is crucial to contain the excess thyroid hormone production, especially during pregnancy, to ensure safe childbirth. It is also important to understand the various causes of hyperthyroidism in pregnancy, based on which you can opt for the best course of treatment.

Hyperthyroidism in pregnancy is not a very common condition among women. The condition severely impacts over 0.1% to 0.4% of pregnancies, where the thyroid hormone in women increases drastically.
One of the most sought-after treatments for hyperthyroidism is the administration of antithyroid drugs (ATDs). As these drugs can cross the placenta in some cases, opting for surgery to remove the thyroid gland may also be effective.
The most common symptoms of hyperthyroidism in pregnancy include sudden weight loss, shaky hands and high blood pressure. Some women may also experience irregular or fast-paced heartbeat.
Pregnant women tend to produce more thyroid hormones than usual. This can sometimes become significantly more than the need of the body and lead to active metabolism or hyperthyroidism. If left untreated, the condition can result in preterm birth or complicated childbirth. In some cases, it may also impact the child’s health.
You can naturally improve your hyperthyroidism during pregnancy by focusing on having the correct diet and exercising on a daily basis. Including vegetables like cauliflower and cabbage can slow down the production of the thyroid gland to some extent. You must also avoid Iodine-rich food that can cause an increase in thyroid hormone production.
Early labour and reduced baby weight can be the most common effects of hyperthyroidism in pregnancy. In severe cases, the condition can also be life-threatening for the mother.
Yes, you can develop hyperthyroidism for the first time during pregnancy. This is likely due to the steep increase in the human chorionic gonadotropin (hCG) hormone during the first trimester. However, the condition tends to resolve itself by the second trimester.
Hyperthyroidism in pregnancy can cause certain impacts on the baby as well. This includes reduced weight or early childbirth. The condition can also result in the overall poor health of the baby.
Yes, in some cases, pregnancy can lead to hyperthyroidism. This is primarily because of the higher hCG levels during the initial months. This results in more production of the thyroid hormone but often gets resolved with time.
Hyperthyroidism in pregnancy is caused by many factors but the most common condition is Graves’ disease. Others may include high levels of hCG, increased intake of iodine or overdose of certain medications.
The first line of treatment to control hyperthyroidism in pregnancy is antithyroid drugs. They can bring relief to the condition and reduce hormone production. Additionally, proceeding with surgery can also be an effective long-term solution.
Mothers experiencing hyperthyroidism during pregnancy can be at risk of heart failure due to excess hormone production. High blood pressure and increased heart rate can lead to other severe conditions as well.
In some cases, hyperthyroidism can lead to poor health for the baby. This commonly includes premature delivery or the reduced body weight of the child.
The thyroid can be transferred from a mother to the baby since it is a hereditary disease. Thus, children are likely to witness certain symptoms of the disease if anyone in their family had it previously.
In the cases where your hyperthyroidism is not correctly treated, it can increase the chances of a miscarriage during pregnancy. In certain cases, it also negatively impacts the fertility of the woman.
It is often safe for mothers to breastfeed while being on antithyroid medicines. However, it is best to have the drugs in small amounts and get regularly checked for your exact thyroid levels.
Doctors often check the thyroid levels of a pregnant woman every month. This helps in ensuring that the levels stay within limits. In cases of evident and prolonged symptoms, dedicated tests can be done to diagnose the condition.
Due to the high levels of hCG causing increased production of the thyroid hormone, hyperthyroidism is generally common during the first trimester of pregnancy. In most cases, the levels return to normalcy by the second trimester, not requiring any course of treatment.
Untreated or poorly controlled hyperthyroidism in pregnancy can lead to various complications for the baby, such as preterm birth, low birth weight, thyroid dysfunction, and fetal or neonatal thyrotoxicosis.
Hyperthyroidism in pregnancy is a condition where the thyroid gland produces too much thyroid hormone, which can cause various complications for both the mother and baby. Symptoms may include rapid heartbeat, weight loss, anxiety, or difficulty sleeping.
