Hypothyroidism is a condition where the thyroid gland, located in the neck, does not produce enough thyroid hormones. These hormones are essential for regulating metabolism, energy levels, and overall body functions. When the thyroid is underactive, people may experience symptoms like fatigue, weight gain, and sensitivity to cold. This condition can affect anyone but is more common in women and older adults. Treatment typically involves taking synthetic thyroid hormones to restore normal hormone levels. With proper management, individuals with hypothyroidism can lead healthy, active lives and alleviate many of the symptoms associated with the disorder.
