Diuretics or Water Pills
Taking a diuretic or “water pill” may contribute to low magnesium levels. These drugs treat high blood pressure, heart failure, and edema (swelling caused by excess fluid). The connection between diuretics and magnesium deficiency can cause serious problems, including muscle weakness, numbness, and tingling in the hands or feet. Diuretics may also interfere with the absorption of other vitamins and minerals. In addition to the above health risks, prolonged use of diuretics can lead to potassium deficiency (associated with heart rhythm disturbances).
However, they can cause dehydration, leading to increased kidney magnesium loss. If a person is taking a diuretic and has recently noticed worsening symptoms of low magnesium levels (muscle weakness or numbness), talk with a doctor about alternative treatments that won’t deplete the body of this mineral as quickly.
