What happens when you do not get enough magnesium?

People who do not get enough magnesium can develop osteoporosis, according to the University of Maryland Medical Center. The center states that low levels of magnesium may also play a role in the development of asthma, high blood pressure and cardiac abnormalities.

While a magnesium deficiency is not common, certain people have higher risks, including people who take diuretics or "water pills," people who abuse alcohol, people suffering from kidney disease and people who have chronic diarrhea or vomiting, according to the University of Florida. The University of Florida states that symptoms of a magnesium deficiency include loss of appetite, abnormal heart rate, confusion, seizures and high blood pressure.

A magnesium deficiency can also cause numbness, tingling, muscle cramps and personality changes, according to the National Institutes of Health Office of Dietary Supplements. In healthy individuals, the kidneys help the body retain its existing stores of magnesium by limiting the amount that is lost through urination. The National Institutes of Health Office of Dietary Supplements states that rich food sources of magnesium include: nuts, seeds, legumes, green leafy vegetables, whole grains, whole milk, yogurt and fortified cereals. For those with magnesium deficiencies, dietary supplements may be recommended, according to the National Institutes of Health Office of Dietary Supplements. The National Institutes of Health Office of Dietary Supplements warns that while supplemental magnesium is effective in correcting magnesium deficiencies, it can sometimes cause abdominal cramps and diarrhea.
