Myxedema Coma

Myxedema Coma Overview

The thyroid gland, located at the front part of the neck, is responsible for making substances called thyroid hormones that are important for all body cells to work properly.

In certain conditions, the thyroid becomes underactive and produces fewer amounts of its hormones, a situation called hypothyroidism. People with hypothyroidism have problems that reflect underactivity of the organs of the body, resulting in symptoms such as fatigue, feeling cold, weight gain, dry skin, and sleepiness. When the levels of thyroid hormones become very low, the symptoms get worse and can result in a serious condition called myxedema coma. Myxedema coma is a rare but life-threatening condition. People with hypothyroidism who are in or near a coma should be taken to an emergency department immediately.
