Hypomagnesemia is a medical condition characterized by low levels of magnesium in the blood. Magnesium is an essential mineral that plays a crucial role in various bodily functions, including muscle and nerve function, blood sugar control, and blood pressure regulation. Normal magnesium levels are vital for overall health, and low levels can lead to symptoms such as muscle cramps, fatigue, and irregular heart rhythms. The causes of hypomagnesemia can include inadequate dietary intake, certain medical conditions, and the use of specific medications. Treatment typically involves dietary changes to increase magnesium intake or supplementation, depending on the severity of the deficiency. Regular monitoring and management are important to prevent complications.
