Which conditions affecting the small intestine hinder the body's ability to absorb magnesium from food?

Crohn's disease or celiac disease

A common pathway leading to magnesium deficiency involves compromised gastrointestinal function, particularly impairment of the small intestine, which is the primary site for mineral absorption. Inflammatory or autoimmune conditions such as Crohn's disease or celiac disease directly damage or alter the structure of the small intestinal lining. This compromised state severely hinders the body's efficiency in absorbing essential nutrients, including magnesium, from ingested food, thereby leading to chronic depletion even if dietary intake appears adequate. These digestive disorders represent a significant cause of deficiency separate from issues related to absorption blockers (like certain medications) or increased excretion.
