Nosebleeds are rarely a cause for serious concern. Children are known to be inquisitive and experimental by nature, and sticking objects into their nose is a common occurrence. Other common causes for periodic nosebleeds are dry air or allergies. In these cases, parents usually discover the cause of the nosebleeds and can solve the issue, even if it requires a visit to the child’s pediatrician for allergy treatments.

Excessive nosebleeds that seem to persist or happen rather suddenly and often can be a symptom of a more serious issue. If your child or teenager experiences sudden, problematic nosebleeds for no apparent reason, you should see a vascular specialist for an examination. Excessive nosebleeds can be the first obvious sign of a rare genetic condition known as Hereditary Hemorrhagic Telangiectasia (HHT) or Osler-Weber-Rendu Disease.

What is Hereditary Hemorrhagic Telangiectasia (Osler-Weber-Rendu Disease)?

This condition causes abnormally dilated blood vessels and the formation of connections between arteries and veins, called arteriovenous shunts. These can develop in any organ or bodily system, but are most common in the brain, lungs, liver and nose. Surface occurrences most often develop on the face, hands and chest. They appear bright red or purple and typically increase in number as the person grows older.

These formations can easily rupture and bleed, causing anemia or other complications; this propensity to bleed easily is why nosebleeds are a common first symptom. Other symptoms can include:

  • Fatigue
  • Dark or bloody stools
  • Shortness of breath
  • Headaches
  • Seizures

Unfortunately, internal vascular malformations can go undetected without advanced imaging. When excessive nosebleeds occur or other visible formations appear, a vascular specialist will likely schedule ultrasound, bubble tests for blood flow, MRI and/or CT scanning to determine if other malformations are present in the body.
