Hereditary Haemorrhagic Telangiectasia

Hereditary haemorrhagic telangiectasia is an inherited condition in which blood vessels form abnormally. Small vessels on the skin and lining of the nose and gut are fragile and bleed easily, causing frequent nosebleeds and anaemia. Larger vessel malformations can occur in the lungs, brain and liver. Care involves regular screening, bleeding control and treatment of the malformations.
