Answer:
too much calcium
Step-by-step explanation:
People who ingest large amounts of calcium, such as those with peptic ulcers and who drink milk and calcium-containing antacids, may develop a hypercalcemia that is excess calcium in their blood.
Excess calcium in the blood can weaken bones and muscles, lead to the formation of kidney stones and interfere with the functioning of the heart and brain.
Calcium is fundamental for the strengthening of teeth and bones, the release of hormones and nerve and brain functions, but when it is in excess it is responsible for causing all these health damages.
