Portal hypertension.

Portal hypertension means high blood pressure in the portal vein, the main vein carrying blood from the gut to the liver and is different from high blood pressure. This may occur due to scarring in the liver, which causes backpressure to the portal vein. This may cause veins like varicose veins to develop in the lining of the gut, stomach or gullet.

These veins become fragile and bleed. It is rare for this to occur before the child is two years old. Bleeding can cause black stools, pallor or vomiting of blood. If bleeding does occur, then contact your local hospital immediately. Treatment is available.

• Itching (Pruritus)

Some children with reduced bile flow experience itching of the skin. This can develop at any time and can make a child quite irritable and miserable. If you think your child may be affected consult your GP or specialist unit additional medicines may be required.
