Hypothyroidism
(Underactive Thyroid)
Hypothyroidism, or underactive thyroid, is a condition where the thyroid gland does not produce enough hormones, causing a slow metabolism. This is usually caused by Hashimoto's thyroiditis, an autoimmune disorder. Common symptoms include fatigue, weight gain, cold intolerance, dry skin, constipation, depression and slow heart rate. This may mainly affect women, especially more than 60 people, and iodine deficiency, thyroid surgery or some drugs. The diagnosis is made through blood tests measuring TSH and T4 levels. Treatment usually involves regular monitoring to effectively manage daily hormone replacement and hormone levels with levothyroxine.
