Magnesium absorption

Q: Absorption of magnesium occurs in the? (select one)

A) proximal intestine 
B) distal intestine


Answer: B

The absorption of magnesium occurs in the distal intestine including the colon. This becomes clinically important as magnesium does not have huge deposition in the body and patients with distal colectomy or with distal small intestinal and colonic disease may develop life-threatening hypomagnesemia resulting in arrhythmias and neurological symptoms.
