Telangiectasia Hemorragica Hereditaria is not a contagious disease, but genetic and Hereditary with a 50% chance of transmission to the offspring. If the nosebleeds are the most obvious and tell-tale, it is associated with other problems based on the presence of vascular malformations in other organs which is why it is very important to track them and treat them. It is not a curable disease as there are so many other as high blood pressure, but it HAS treatments for any of the conditions that could cause.
It is very important to counsel and treat the family,
