User: Too much calcium in a person's diet may result in A. heart attack. B. dehydration. C. kidney stones. D. high blood pressure.

Weegy: One of the major symptoms of too much calcium in one's system is extreme lethargy, to the point that a person is not even interested in basic functions, such as food intake. [ Additionally, a person may experience intense or consistent bouts of nausea, vomiting and diarrhea, which in turn can result in a high level of dehydration and thirst. More serious symptoms of too much calcium can include an irregular heartbeat and extremely low blood pressure. Those who allow the condition to worsen through time can lose consciousness or feel confused much or nearly all of the time. Depression is another major symptom of having too much calcium in one's system, as is abdominal pain. Kidney pain is also a sign, and this signals not only high levels of calcium but the possibility of kidney stones or even kidney disease. ]
