E89: Postprocedural endocrine and metabolic disorders, not elsewhere classified
E89.0: Postprocedural hypothyroidism
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. Your thyroid gland is producing insufficient messenger substances. The cause of this is a treatment or examination. There are various diseases where the thyroid gland has to be partially removed, for instance. In that case, there are no longer enough of many thyroid gland messenger substances in the blood.
If you have insufficient messenger substances in your body, you may have typical symptoms. For example, you might move more slowly or not be able to think as quickly. You may also have dry skin or constipation.
