Consider routine magnesium level monitoring during semaglutide-induced weight loss. Ensure adequate dietary magnesium intake or discuss supplementation with your provider. Report muscle cramps, fatigue, or irregular heartbeat, which may indicate deficiency.
Why this interaction occurs
Rapid weight loss associated with semaglutide use, combined with reduced caloric and nutrient intake, can contribute to magnesium depletion. Magnesium is critical for insulin signaling, glucose metabolism, and cardiac function. Deficiency may also reduce the effectiveness of glycemic control and increase cardiovascular risk.
