What is the Origin of Vitamin Malabsorption?

The term is rooted in clinical gastroenterology, where the complex physiological process of nutrient absorption has been studied for centuries. Malabsorption is a descriptive term for the failure of this critical process, frequently observed in conditions affecting the small intestine, such as celiac disease or post-surgical changes.

What is the Mechanism of Vitamin Malabsorption?

The mechanism varies depending on the vitamin class; for instance, fat-soluble vitamins require adequate bile and pancreatic enzymes for micelle formation and transport across the intestinal brush border. A defect in any stage—reduced surface area, transport protein malfunction, or bile acid deficiency—results in insufficient delivery of these vital cofactors necessary for numerous hormonal synthesis and metabolic pathways.

Vitamin Malabsorption

Meaning

A pathophysiological state characterized by the inadequate assimilation of essential fat-soluble or water-soluble vitamins from the lumen of the gastrointestinal tract into the systemic circulation. This condition is often a sequela of underlying mucosal damage, chronic inflammatory conditions, or pancreatic enzyme insufficiency. Chronic malabsorption directly compromises endocrine function and cellular health due to a lack of vital cofactors for metabolic processes.
