Hypothyroidism in Pregnancy: Signs, Risks & How to Protect Your Baby

Pregnancy is a critical period during which the body of a woman changes drastically in terms of hormones and metabolism to accommodate the growing baby. Thyroid disorders, and in particular, hypothyroidism are one among the numerous health conditions that may be experienced during pregnancy. The thyroid gland is necessary in maintaining metabolic rates, energy and balancing of hormones all of which are vital in a healthy pregnancy.


Thyroid diseases are not uncommon in women of child bearing age in India. It has been found out that about 2-3 % of pregnant women can experience hypothyroidism, but mild or sub-clinical cases are, probably, left undiagnosed. When a woman is pregnant, thyroid hormones play a crucial role in brain development of the baby and mostly during the first trimester when the fetus solely relies on the hormone supply of the mother.


Hypothyroidism may cause complications to the mother and the baby in case it is not addressed. A pregnancy thyroid test in Noida and consultation with the best gynecologist in Noida can help avert dangers at early stages and result in a healthy pregnancy process.


Feeling unusually tired, gaining excess weight, or noticing swelling during pregnancy? Don’t ignore these signs—thyroid imbalance can affect your baby’s development. Call +91 9667064100 to consult a specialist in Noida today.

 

Hypothyroidism in Pregnancy?

Understanding hypothyroidism in pregnancy? is essential for early detection and proper care. Hypothyroidism is a condition, which develops as a result of insufficient production of thyroid hormones (T3 and T4) by the thyroid gland necessary in metabolic processes and fetal development.


The need of thyroid hormones in the body is very high during pregnancy. In case the thyroid gland is inept or incapable of fulfilling this, then it causes hypothyroidism. This disease may be preexisting or it may develop in pregnancy because of hormone changes.


The thyroid hormones are crucial in the development of the fetal nervous system and brain. During the early period of pregnancy, the fetus completely depends on thyroid hormones of the mother. Any shortcoming in this age may have an impact on intellectual growth of the baby.


Medical practices have suggested regular thyroid tests on high-risk pregnant women to detect and treat these diseases at an early age.


Symptoms of Hypothyroidism in Pregnancy

Recognizing the symptoms of hypothyroidism in pregnancy can be challenging because many symptoms overlap with normal pregnancy changes. Nevertheless, there is some evidence that there is a thyroid imbalance.
 

Common symptoms include:
 

  • Excessive fatigue beyond normal pregnancy tiredness

  • Unexplained weight gain

  • Dry skin and hair

  • Constipation

  • Sensitivity to cold

  • Swelling in the face or hands

The symptoms are experienced because of low rates of metabolism because of low levels of thyroid hormones. Indicatively, low energy metabolism is associated with fatigue and weight gain.


Pregnant women should inform their doctor about constant or unusual signs because when they are detected in good time, the complications are avoided.


Complications of Untreated Hypothyroidism
