condition where thyroid gland produces insufficient thyroid hormones
Hypothyroidism, also known as underactive thyroid, is a condition where the thyroid gland does not produce enough thyroid hormones. These hormones are crucial for regulating metabolism, and their deficiency can lead to symptoms such as fatigue, weight gain, and hair loss. In severe cases, untreated hypothyroidism can lead to more serious health issues like heart disease and infertility.
