What anatomical site is compromised in conditions like Crohn’s disease or Celiac disease, leading to severe magnesium absorption hindrance?
Answer
The ileum, as this specific location is the primary site where magnesium absorption naturally takes place.
Absorption of minerals is highly dependent on the integrity and location of the digestive tract structures. For magnesium, the vast majority of efficient absorption occurs specifically in the ileum, which is the final section of the small intestine before the large intestine. Conditions that cause inflammation or damage to the intestinal lining, such as Crohn's disease or Celiac disease, or surgical interventions like gastric bypass surgery, severely compromise the function of the ileum. This structural impairment directly restricts the body’s ability to draw magnesium from food into the bloodstream.
