Once bleeding has stopped, the sufferer should avoid any strenuous activity for 12 hours. Nor should they blow their nose, as this may dislodge blood clots and cause bleeding to start again. If bleeding does not stop after 30 minutes of direct pressure, patients should see a doctor. If blood runs down the back of the throat when pressure is applied to the nose, it could be a higher-septum nosebleed and require a visit to the doctor. Patients should also seek professional help if the nose is deformed after an injury, if blood runs down the back of the throat when pressure is applied to the nose or if nosebleeds occur often.
Cauterisation is the minor surgical procedure used to stop heavy nosebleeds.
It involves destroying tissue with an electric current, a hot iron, or caustic chemicals. This seals the ruptured blood vessel and prevents further bleeding. This page contains basic information. If you are concerned about your health, you should consult a doctor.
