E83.5: Disorders of calcium metabolism

Disorders of calcium metabolism, coded as E83.5 in the ICD-10 WHO 2016 Classification Manual, refer to conditions where the body is unable to maintain appropriate levels of calcium. Calcium is crucial to the body as it assists in the formation of bones and teeth, blood clotting, muscle contraction, and nerve signal transmission. When calcium levels are too high or too low due to several possible reasons like dietary issues, problems with the parathyroid glands, or kidney disorders, it results in what is known as hypercalcemia and hypocalcemia, respectively. Symptoms for these disorders can vary, but often include muscle aches, fatigue, frequent urination, and feelings of confusion or depression. The speed and severity of disease progression can also depend on various factors including the underlying cause and whether the individual presents with chronic or acute symptoms. The main body systems affected by these disorders include the circulatory, skeletal, muscular, and nervous system.
