Malabsorption is a general term for impaired absorption of nutrients by the small intestine. It may be caused by many conditions, including cystic fibrosis , celiac disease, Crohn’s disease, pancreatitis, parasitic diseases such as giardiasis, and intestinal damage.
Certain medications and surgery on the intestine or stomach may also be causes.
Common symptoms of malabsorption are weight loss, diarrhea, bloating, gas (flatus), abdominal pain, tiredness, and weakness. In severe cases, there may also be malnutrition, vitamin or mineral deficiencies, or anemia.
Treatment is of the underlying cause, if possible. Dietary modification or supplements may also be needed.
