Hereditary telangiectasia is a medical disorder that affects the blood vessels and is a genetic disorder that can be inherited. It is also called hereditary hemorrhagic telangiectasia and Osler-Weber-Rendu syndrome.

When the blood vessels do not develop properly it will cause bleeding that can lead to anemia and more serious complications. In a normal, healthy body, arteries branch off into smaller blood vessels until they became a network of capillaries or tiny blood vessels that provide oxygenated blood to body tissues and organs. The blood pressure in the capillaries drops before the blood flows on to the veins and into the heart.

In hereditary telangiectasia, some of the blood vessels from the arteries directly join the veins which are an abnormal set up in the capillaries. This condition is called arteriovenous malformations or AVMs. When these AVMs are formed in the small vessels near the skin surface, they are known as telangiectasia where it is visible as red spots. When they form in the lining of the nose or the gut, there is a possibility of easy bleeding. Additional symptoms can be seen in childhood or in the teenage years. Examples are:
Nosebleeds – this condition can start at any age. It can be frequent and persistent however it can improve with age. The abnormal blood vessels are formed in the lining of the nose. When the bleeding is not managed immediately this can result in iron-deficiency anemia, especially if no iron supplements are provided.
Red spots or purple spots underneath the skin or telangiectasia – Abnormal blood vessels may start to appear under the skin from ages 20-30 years. It can form on the fingertips, lips, nose or the gut and sometimes on the ears and face. The spots could increase with age. They are not dangerous compared to the other types; however, it can be a cosmetic problem.
Abnormal blood vessels or AVMs – they are formed inside the body organs and tissues. Some affected individuals will not experience any symptoms; in fact, some are not aware they have this condition. Usually, treatment is applied after weighing the consequence of just living the AVMs alone. Some AVMs need to be treated while others don’t.

One example where an AVM needs to be treated is when it is formed in the lungs, which can cause low blood oxygen and allows the formation of blood clots. Blood clots can be life-threatening if it will lodge in the brain. It can lead to stroke.
