Medium-chain triglycerides can be used in the management of gastrointestinal diseases when fat digestion is impaired
For fats to be absorbed across the small intestine wall, they have to be hydrolysed in the lumen before they can enter the lacteals in the villi. This hydrolysis requires pancreatic lipase and bile salts, as well as intact villi, so diseases of the pancreas, liver or small intestine impair this process resulting in malabsorption of dietary fat.
Most triglycerides in the diet contain 16-24 carbon atoms, but medium-chain triglycerides contain only 8-12 carbons, and this changes their physical characteristics. They are much more water soluble, and as a result can be absorbed across the small intestine wall into the blood stream, not into the lacteals. Mainly they are transported direct to the liver via the portal vein, but some are transported as chylomicrons via the thoracic duct.
Commercial MCT oil is derived from coconut oil and its characteristics are :
So, MCT oil may be used as an energy and fat source in patients with :
However, because the medium-chain triglycerides are transported direct to the liver there is the risk of hepatic lipidosis (especially in cats) developing in susceptible patients if high doses are given. In addition the following side-effects have been reported :
