Hypothyroidism is among the most common endocrine diagnoses in Chennai. Fatigue, weight gain, and menstrual changes among professional women across T Nagar, Adyar, and OMR are frequently attributed to stress when the underlying cause is treatable thyroid dysfunction.

Residents of T Nagar, Anna Nagar, and across the city with chronic conditions, those on long-term medication, and individuals with a relevant family history should test at the frequency their specialist recommends.
