Written by : DoctorNDTV Team

There are several possible causes of a nosebleed. These include:

  • Excessive nose picking
  • Frequent and forceful nose blowing or sneezing during cold or allergies
  • Dry air which can be a problem in cold climate due to which the mucous membrane or lining in the nose becomes dry, cracked and prone to bleeding
  • Certain medication such as nose sprays can cause nosebleeds as a side effect
  • Injury to the nose
  • Infection in the nose
  • Recurrent nosebleeds may be a symptom of any other condition such as high blood pressure, bleeding disorder or a tumour of the nose
