Magnesium deficiency in patients on home enteral nutrition.
Home enteral nutrition (HEN) is an established method of long term nutritional support. Many patients receiving HEN have Crohn's disease complicated by intestinal failure and malnutrition, including magnesium deficiency. It is unknown if HEN can correct magnesium deficiency or if patients on HEN can become magnesium deficient. We measured total magnesium intake in nine patients receiving HEN, and assessed their magnesium status. Two patients had magnesium intakes below the recommended dietary allowance of 15 mmol/day. Four patients (44%) had biochemical evidence of magnesium deficiency, although no patient had clinical signs of magnesium deficiency. Several magnesium deficient patients used a liquid feed which had a low magnesium content. Patients on HEN should have their magnesium status checked regularly and may require magnesium supplements.
