Malabsorption is a state arising from abnormality in digestion or absorption of food nutrients across the gastrointestinal(GI) tract. Impairment can be of single or multiple nutrients depending on the abnormality. This may lead to malnutrition and variety of anaemias.Some prefer to classify malabsorption clinically into three basic categories: (1) selective, as seen in lactose malabsorption; (2) partial, as observed in a-Beta-lipoproteinemia, and (3) total as in celiac disease.
