Hypothyroidism can lead to infertility
Hypothyroidism can lead to infertility, increased miscarriage risk, and complications in both mother and baby. 50 to 70% of hypothyroid female patients have menstrual abnormalities. Many present with oligo menorrhea (scanty bleeding during cycle). Severe hypothyroidism is commonly associated with failure of ovulation and infertility. Ovulation and conception can occur in mild hypothyroidism. But these pregnancies are at risk of abortions, stillbirths, or prematurity.
What is subclinical hypothyroidism?
SCH is classically defined as a thyrotropin (TSH) level above the upper limit of normal range (4.5−5.0 mIU/L) with normal free thyroxine
(FT4) levels. Women with unexplained infertility more commonly present with this condition than women with infertility due to a known cause.
Should non-pregnant women be treated for SCH (subclinical Hypothyroidism)?
There is no benefit from the standpoint of lipid profile or alteration of cardiovascular risk in non-pregnant women. The risk of over-treatment with thyroid hormone can result in bone loss. Hence refrain from self-treatment with thyroid hormone and consult your doctor for proper advice.
