Description : What is the line of management in defective absorption?

Last Answer : In such cases, triglycerides with short chain and medium chain fatty acids are digested and absorbed properly, because they do not require micellerisation for absorption. Since milk fat and coconut oil are made up of MCT, they are therapeutically useful in malabsorption syndromes.

Description : Any other cause for defective absorption of fat?

Last Answer : Any condition leading to a deficiency of bile salts can also result in malabsorption of fat. The most common causes are obstruction to biliary tract due to gall stones, tumours of head of pancreas, enlarged lymph glands, etc.

Description : What is the cause for defective absorption of fat?

Last Answer : It may be due to diseases in intestinal mucosa, e.g. coeliac disease, sprue, Crohnís disease.
