What are some diseases caused by too much calcium?

Consuming excessive amounts of calcium can cause hypercalcemia, a condition in which calcium levels in the blood are too high, explains Healthline. Hypercalcemia affects multiple organs of the body and causes side effects such as muscle twitching and weakness, nausea, abdominal pain, curvature of the spine and bone pain.

Hypercalcemia can also affect the kidneys, causing excessive urination, excessive thirst and, in severe cases, kidney stones and kidney failure, according to Healthline. Psychological symptoms of hypercalcemia include depression, irritability, memory loss, confusion and dementia. Treatment options for hypercalcemia include corticosteroids, intravenous fluids, intravenous bisphosphonates, loop diuretic medications, and dialysis to remove excess calcium and waste from the blood.
