The effect of the Alagille Syndrome can be seen in heart, lungs and physical appearance. The Alagille Syndrome narrows or deforms the Bile Ducts in the body. Bile Ducts help to digest fat in the liver and pass it to gallbladder and Small Intestine. However, due to the reduced amount of the ducts, Liver starts underperforming. The impaired blood flow often causes serious problems between heart and lungs. The heart defects due to Alagille Syndrome is known as Fallot. Distinct physical appearance also points towards the Alagille Syndrome. It has been noticed that children with a broad forehead pointed nose, and deep eyes tend to have the syndrome.

It allows the fat to digest, and a deficiency of Fat Soluble vitamins like A, D, E and K can be avoided.

The breast milk mother is generally helpful for the natural treatment. However, additional MCT is provided to the infants for increase of Bile Ducts. MCT stands for medium-chain triglycerides and is helpful for releasing of bile ducts that in turns control the rest of the criticality.

Ursodeoxycholic Acid or Ursodiol are also used as per the medication to increase the bile duct flow in the system. Antihistamines are also used to control itching in the body. Rifampin is used for the same purpose. However, medicine like cholestyramine and colesevelam are used to reduce the bile salt from the body.

However, in extreme cases surgery may also be performed in order to save the infant. If the liver cells are damaged then liver transplantation might be considered.
