How does nose bleeding develop?

Small injuries of the fine vessels in the nasal mucosa lead to nosebleeds. Nosebleeds are usually harmless and may even occur for no reason. The loss of blood is minimal in most cases, but annoying when the blood comes unexpectedly on the clothes. The nasal mucosa is a very well-perfused tissue because it has to do a tremendous job. An average of 10, 000 to 15, 000 liters of respiratory air are heated by the nose over a distance of about 7 cm to a temperature of 30 degrees Celsius and over 90% saturated with water vapor.

Causes of nosebleeds

Nasal bleeding is caused by the bursting of a blood vessel in the nasal mucosa. The reasons for the annoying bleeding are manifold:

  • Acute infections like the flu
  • Injuries or a slap on the nose
  • Cold, hay fever
  • Slight vascular injury z. B. when Naseputzen
  • Desiccation through room air conditioning
  • Side effect of drugs that affect blood clotting

What should I do?

Hover up the upper body, bend the head forward - not backwards as often said before - and place a cold cover in the neck to reduce the blood flow to the nasal mucosa. In addition, squeeze the nostrils for a few minutes. If blood flows down the throat - do not swallow, but spit it out as much as possible. Also helpful is a nasal tamponade or a compress.

If the bleeding is breastfed, do not bleed for a few hours. Anyone who suffers from a sensitive nasal mucosa and therefore easily prone to nosebleeds, especially in case of runny nose rub the nose inside with nourishing nasal ointment and avoid heavy whistling.

Nosebleeds - not always harmless

In some cases, however, the doctor must be consulted: If the bleeding has not stopped after 20 minutes or is bilateral or with frequent nosebleeds for no reason. Nosebleeds can also be an indication of other diseases. These include z.
