Surgey is needed to treat bleeding in some areas. Frequent or heavy nosebleeds may be treated with electrocautery or laser surgery.
Endovascular embolization may be needed to treat abnormal blood vessels in the brain and other parts of the body.
Some patients respond to estrogen therapy, which can reduce bleeding episodes. Blood-thinning medications should be avoided. Some patients may need to take antibiotics before having dental work or surgery. Ask your doctor what precautions you should take.
