Thyroid Levels

Can a woman with a thyroid disorder get pregnant? The answer is yes, as long as she takes the right precautions. However, there are certain factors that may influence her chances of getting pregnant and being healthy during pregnancy. Here’s our list of the most important things to know about hypothyroidism and pregnancy.

About Thyroid Disease

The thyroid gland is located in the neck and produces hormones that help regulate your metabolism. Your thyroid gland also controls how fast your body grows and how fast you lose weight. If your thyroid isn't working properly, it can affect your health in many ways. You may feel tired, have trouble losing weight, or have menstrual problems.

Role of thyroid hormones in pregnancy

Thyroid hormones are essential for normal fetal development. They also play a key role in the health of the mother and child. During pregnancy, thyroid hormones go up and help to maintain a healthy pregnancy. The fetus also has thyroid hormones, which are produced by the placenta and are necessary for normal growth and development.

According to research on 400 women group, almost suffering from infertility, 24% of participants were found to have hypothyroidism — but within a year of treatment, 76% were able to conceive.

Which thyroid hormones should be tested in Pregnancy?

Thyroid testing is an important part of a woman's routine check-up during pregnancy. It's important to check your thyroid because it plays a role in your baby's brain and nervous system development.

The best way to check thyroid disease is a TSH blood test, that shows the thyroid hormone levels in your body. When your thyroid levels are low, your body will begin to experience symptoms like fatigue, weight gain, and difficulty concentrating. Your doctor may recommend a TSH blood test if you have any of these symptoms.

The TSH range during pregnancy in India is one of the early Indian reports on reference ranges for TSH states values of 0.6–5.0 mIU/L in the first, 0.44–5.78 mIU/L in the second, and 0.74–5.7 mIU/L in the third trimester.

Treatment of thyroid during pregnancy

If you’re pregnant, you need to make sure that you’re getting enough iodine. Iodine is an important mineral for your thyroid gland. Your thyroid gland uses iodine to make thyroid hormones. Without enough iodine, your thyroid won’t work properly.

You can get iodine from the foods you eat like dairy foods, seafood, eggs, meat, poultry, and iodized salt—salt with added iodine. Your doctor can tell you how much iodine you need. In some cases, your doctor may prescribe a thyroid hormone medication to help with your symptoms.
