Patient's Query

Hello doctor,

I am 34 years old and trying to conceive. Is it too late for me to have kids at this age? I am dealing with a thyroid issue, specifically hypothyroidism. Over the past three cycles, my periods have been irregular. Once, they were delayed by more than 10 days, leading me to suspect pregnancy. However, a home pregnancy test turned out negative, leaving me disappointed. I have been diagnosed with hypothyroidism, and although the doctor prescribed medication (50 mcg), I have not been taking it regularly. There was a time when I checked my thyroid levels without medication, and they appeared normal, so I stopped taking the medication altogether. Unfortunately, that is when I started experiencing delayed periods. Recently, my TSH level was found to be 12, prompting the doctor to put me back on 50 mcg of thyroid medication. My periods have always been regular since the beginning, and I already have a 9-year-old son. However, in the past three years, I have experienced two to three miscarriages, one at eight weeks and others very early on. I am wondering if these miscarriages are related to hormonal imbalances. Please help.

Thank you.


Welcome to icliniq.com.

I read your query and can understand your concern.

Hypothyroidism can lead to infertility and miscarriages, posing risks like cretinism (a condition resulting from untreated congenital hypothyroidism, posing risks to fetal development and potentially leading to miscarriages) in the fetus. I suggest regular thyroid medication, monitoring thyroid levels, and fertility hormone assessments (luteinizing hormone, follicle stimulating hormone) are recommended. Additionally, I suggest maintaining a healthy BMI (body mass index) through regular exercise contributes to fertility and a healthy pregnancy.

I hope this helps.

Please revert in case of further queries.

Thank you.
