E89: Postprocedural endocrine and metabolic disorders, not elsewhere classified
E89.2: Postprocedural hypoparathyroidism
The parathyroid glands are 4 small glands at the edge of the thyroid gland. A messenger substance is formed in the parathyroid glands. This messenger substance affects the calcium and phosphate content in the body. Calcium from the bone is dissolved by the messenger substance and released into the blood. It thus also affects bone firmness.
Your parathyroid glands are not producing enough messenger substances. The cause of this is a treatment or examination. For example, if the thyroid gland has to be removed, the parathyroid glands sometimes also must be removed.
If you have too little of the messenger substance in your body, the calcium content in your blood may be too low. You may have various symptoms as a result. It is possible for you to have sensory disturbances or pins and needles on your skin. The muscles may cramp or you might have an irregular heartbeat. At the same time however, calcium may also accumulate in the tissue. The organs may calcify as a result of too much calcium. That can affect the cornea in the eye or the lens of the eye, for instance.
