When there’s an imbalance in thyroid function, it can indeed disrupt the menstrual cycle, leading to irregular periods. As for fertility, thyroid imbalances can also affect a woman’s ability to conceive. To gain a better understanding of this issue, the OnlyMyHealth team spoke with Dr. Dheeraj Kapoor, Chief of Endocrinology at Artemis Hospital Gurugram. Dr. Kapoor can provide valuable insights into how thyroid imbalances impact pregnancy and fertility.

How does the thyroid affect your menstrual cycle

Menstrual Cycle

Dr. Kapoor elaborated, stating, “The thyroid exerts substantial influence on the menstrual cycle. It directly impacts reproductive physiology by affecting the ovaries and indirectly interacts with sex hormone-binding globulin. Additionally, thyroid function modulates metabolism and contributes to the development of ovarian, uterine, and placental tissues.”

He further explained, “An imbalance in thyroid levels, whether excessive or deficient, can result in menstrual irregularities. This may manifest as heavy or light periods, or irregular menstruation. In some cases, thyroid dysfunction can even cause periods to cease for several months, a condition known as amenorrhea.

Dr. Kapoor explained that thyroid imbalance can disrupt the delicate hormonal balance necessary for menstrual regularity. Hypothyroidism, characterized by an underactive thyroid, can lead to irregular or heavy periods due to low thyroid hormone levels affecting ovulation and the uterine lining. Conversely, hyperthyroidism, an overactive thyroid condition, can also disturb menstrual cycles by causing elevated levels of thyroid hormones, impacting menstrual flow and cycle regularity. Additionally, thyroid dysfunction may contribute to conditions like polycystic ovary syndrome (PCOS), worsening menstrual irregularities and compromising reproductive health.

Dr. Kapoor emphasized that thyroid imbalance significantly impacts fertility, as both hypothyroidism and hyperthyroidism can disrupt the delicate hormonal environment crucial for reproductive processes.

“In hypothyroidism, low thyroid hormone levels can lead to irregular ovulation, reduced fertility, and an increased risk of miscarriage,” he explained. “Conversely, hyperthyroidism, characterized by elevated thyroid hormone levels, can affect menstrual regularity and potentially impair fertility. Thyroid dysfunction may also contribute to conditions like PCOS, further complicating fertility issues. Additionally, thyroid antibodies associated with autoimmune thyroid disorders may harm the ovaries and interfere with egg quality.”

Thyroid disorders can lead to complications during pregnancy

“Recognizing the potential complications, it’s important to address thyroid issues during pregnancy. Untreated conditions like hypothyroidism or hyperthyroidism can heighten the risk of adverse outcomes. Hypothyroidism may increase the likelihood of miscarriage, preterm birth, and developmental problems in the baby, while maternal hyperthyroidism can lead to complications such as preeclampsia, preterm birth, and low birth weight. Additionally, thyroid dysfunction could impact the cognitive and neurological development of the baby. Managing and monitoring thyroid function throughout pregnancy is crucial for minimizing these risks and promoting a healthy pregnancy.”

Preventing Fertility Issues Related to Thyroid

Women with thyroid issues can take proactive steps to prevent further complications in fertility. Dr. Kapoor emphasizes the importance of regular thyroid function tests, especially before attempting to conceive, to detect any imbalances early. If hypothyroidism or hyperthyroidism is diagnosed, prompt treatment with medication prescribed by a healthcare professional is crucial.

Monitoring and adjusting thyroid hormone levels throughout pregnancy are essential for maintaining optimal balance. It’s important to stay in touch with healthcare professionals to ensure that thyroid levels remain within the recommended range. Additionally, adopting a healthy lifestyle, including a balanced diet, regular exercise, and stress management, can support overall reproductive health.

Dr. Kapoor advises women with thyroid disorders to communicate their plans for pregnancy to healthcare providers to ensure a proactive approach in minimizing potential complications and achieving successful fertility outcomes.

He emphasizes the importance of maintaining a proper lifestyle by adopting a well-balanced diet rich in essential nutrients, engaging in regular exercise, and managing stress levels.
