Hypothyroidism is a condition in which the thyroid gland does not produce sufficient quantities of thyroxine, a thyroid hormone. Due to the low levels of this hormone, the person may experience various symptoms such as fatigue, unexplained weight gain, difficulty losing weight, reduced tolerance to cold, puffiness of the face, hoarseness of voice, excessive hair fall, muscle and joint pains, fertility problems, or depression.

There are numerous conditions that can lead to a low thyroid level such as autoimmune thyroiditis, iodine deficiency, pregnancy, radiation therapy, and surgical removal of the thyroid gland. Although this condition is common in women, men can also suffer from it.

Fortunately, hypothyroidism is generally manageable with inexpensive medications after timely diagnosis. If left untreated, it may lead to complications such as obesity, goiter, infertility, and heart failure. Hence, patients especially those at high risk should keep a close watch on the symptoms of hypothyroidism.
