Malabsorption is a condition in which the body does not effectively absorb nutrients from food in the small intestine. Malabsorption can be caused by a wide variety of diseases or disorders, including celiac disease, chronic liver disease, chronic pancreatitis, Crohn's disease, and lactose intolerance. Other conditions that can cause malabsorption include some surgeries of the gastrointestinal tract, such as gastrectomy or gastric bypass. Parasitic infections of the gastrointestinal tract and some genetic diseases are other potential causes of malabsorption.
Malabsorption is common and can affect anyone. Some diseases that cause malabsorption are inherited or have a genetic component. Other risk factors for developing a condition or disease that result in malabsorption include having gastrointestinal surgery, alcoholism, or HIV/AIDS. People with certain other conditions, such as type 1 diabetes, autoimmune thyroid disease, autoimmune liver disease, rheumatoid arthritis, and microscopic colitis are also at risk for developing malabsorption.
Malabsorption can involve a difficulty or inability to absorb all nutrients from food, or it can involve only specific nutrients, such as certain carbohydrates, fats, vitamins, or proteins. In a healthy gastrointestinal tract, most absorption of nutrients takes place in the small intestine. Any disease or disorder that interferes with the intestines ability to absorb nutrients can lead to malabsorption. Examples include celiac disease, in which a gluten intolerance damages the small intestine, and some parasitic infections of the gastrointestinal tract.
Malabsorption may also occur when a disease or disorder interferes with the normal mixing of food with digestive juices and acid in the stomach. This can occur when part of the stomach is removed surgically. In addition, any condition that obstructs or impedes the normal production of digestive enzymes may also lead to malabsorption. These conditions include pancreatitis and pancreatic cancer.
Symptoms and complications of malabsorption vary in character and severity depending on the specific cause of the condition and other factors. However, some symptoms and complications are similar in most conditions due to the due to the lack of nutrients that the body receives. These can include weakness and malnutrition. For more information on symptoms, refer to symptoms of malabsorption.
Making a diagnosis of malabsorption and its underlying cause begins with taking a thorough medical history, including symptoms, and completing a physical examination. Diagnostic tests may include imaging studies that examine the small intestine stomach and/or pancreas for abnormalities that lead to malabsorption. These may include endoscopy, colonoscopy, X-rays, and upper or lower GI studies with barium.
A sample of the small intestine may also be taken to examine under a microscope for abnormalities. This is called a biopsy. Blood tests can reveal a large amount of diagnostic information, such as nutritional deficiencies, the presence of anemia, and the presence of high levels of certain antibodies, which may indicate such causes of malabsorption as celiac disease.
It is possible that a diagnosis of malabsorption can be missed or delayed because symptoms can be vague and resemble symptoms of less serious conditions, such as mild gastroenteritis. For more information on misdiagnosis, refer to misdiagnosis of malabsorption.

A diagnosis of malabsorption may be delayed or missed because some symptoms can be vague and may initially be attributed to another less serious condition. For example, gas and abdominal bloating are typical symptoms of malabsorption, but may be overlooked because it is easy to assume it is related to other factors, such as overeating.
