E05.5: Thyroid crisis or storm

The thyroid is a small organ at the bottom of the neck. The thyroid gland needs iodine to produce important messenger substances for the body. These messenger substances influence the heartbeat, digestion, and body temperature, among other things.

A thyroid crisis can cause a range of symptoms, such as palpitations, restlessness and sweats. A high temperature and diarrhea are also possible. The muscles may twitch or be weak. You may also be sleepy and lose consciousness.
