The TSH Range In Pregnancy
Pregnancy is a challenging yet rewarding time: you are bringing a new life into the world and ensuring the health of your growing baby. Part of the key to a healthy pregnancy is understanding the proper hormonal balance of your body. One of the hormones to pay special attention to is Thyroid Stimulating Hormone (TSH).
What is TSH?
TSH is a hormone produced in your pituitary gland, located in the base of your brain. It is responsible for regulating thyroid hormones, which help control your metabolism, heart rate, growth and mental development. In women, a healthy level of TSH during pregnancy is essential for the health of the baby.
What Are Normal Levels of TSH in Pregnancy?
The normal range of TSH in pregnancy is somewhere between 0.1-2.5 mIU/L. In the first trimester, the best outcomes have been observed when the TSH level falls in the range of 0.1-2.0mIU/L, which is slightly lower than the general target range for non-pregnant adults. During the third trimester, a target range of 0.2-3.0 mIU/L is recommended.
How Is TSH Level Measured?
Your doctor will normally order a blood test to measure your TSH throughout your pregnancy at regular intervals. The normal method of measurement is the laboratory test that measures the amount of TSH in a blood sample.
What Can Affect My TSH Level?
There are a few things that can affect your TSH level, such as:
- Medications – certain medications, such as steroids and beta-blockers, can affect your TSH.
- Changes in Diet – drastic changes to your diet and nutrition can cause your TSH level to alter.
- Excessive Stress and Anxiety
- Lack of Sleep
What Happens If My TSH Level Is Out Of Range?
If your TSH level is above the target range during your pregnancy, you may be at risk of giving birth prematurely and your baby may have a low birth weight. If your TSH level is below the target range during your pregnancy, you may have an increased risk of complications such as preeclampsia. discuss the situation with your doctor. In some cases, medications may be recommended or you may be referred for further testing.
Pregnancy presents many unique challenges, but having a good understanding of TSH level is important for the health of your baby. Knowing the normal target range and what can affect your TSH level helps you to stay on top of your health and make sure that you and your baby remain healthy throughout your pregnancy.
