How PCOS and an underactive thyroid are related?

PCOS and an underactive thyroid (hypothyroidism) are different conditions that can sometimes be related. 

PCOS is a hormonal disorder, while thyroid disorders are related to the production, release, and regulation of hormones from the thyroid gland. Although thyroid dysfunction is not the sole cause of PCOS, it has been shown to play an important role in exacerbating symptoms associated with the condition. Hypothyroidism can cause hormonal imbalances that may exacerbate PCOS symptoms. 

Research also suggests that women with both hypothyroidism and PCOS may have higher levels of luteinizing hormone (LH), which is known to contribute to irregular menstrual cycles and lead to fertility issues.

Additionally, some of the symptoms of hypothyroidism, such as weight gain, fatigue, and irregular periods, can overlap with PCOS symptoms, making it difficult to diagnose one condition without considering the other.

In some cases, hypothyroidism and PCOS may coexist due to shared risk factors. If you suspect any such symptoms, you can visit the Chennai PCOS clinic to help you determine an accurate diagnosis to start an appropriate treatment.
