A fairly common phenomenon and although it might look scary, it rarely is a symptom of a serious problem. The front and back of the nose is lined by blood vessels that are fragile and hence bleed easily making it a common phenomenon among both adults and children.
Nose bleeds are of two types:
- Anterior nosebleeds occur due to the blood vessels in the front
- Posterior nosebleeds due to the ones at the back and causes blood to flow down the throat. This condition can be quite dangerous.
Why does it happen?
Sudden nosebleeds are rarely serious and it’s the more frequent ones that could be problematic. There are certain factors that could trigger a nose bleed:
- Dry air is one of the common causes as it dries out the nasal membrane which causes the tissues inside to crust. Crusting causes irritation and itching which makes you scratch or pick your nose, causing bleeding.
- Certain medicines like antihistamines and decongestants can also dry up the membrane.
- Allergic reactions
- Respiratory infections
- Cold air
- Foreign objects and chemical irritants
- High BP
- Bleeding or clotting disorders
Nosebleeds don’t require medical attention unless they last longer than 20 minutes or after a serious injury. You can treat the nosebleeds at home itself, just squeeze the soft part of your nose making sure your nostrils are closed and lean forwards slightly. Breathe through your mouth and stay this way for 10 minutes.
Sit up straight and avoid lying down as you might swallow the blood causing irritation in the stomach. You can also use a cold compress over your nose to help cool it down and stop the bleeding.
