Hypothyroidism - Symptoms, Causes & Treatment
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, leading to a slowdown of the body's metabolic processes.
Overview
Hypothyroidism is one of the most common thyroid disorders, affecting approximately 11% of the Indian population. Women are 5-8 times more likely to develop it than men.
The condition develops gradually and if left untreated can lead to serious complications including heart disease, infertility, and myxedema coma. With proper medication, most people with hypothyroidism can live normal, healthy lives.
