What happens when you rub your nose and bleed, what should you do if you bleed when you touch your n

Nosebleeds are a very common symptom. This is because there is a septum in the middle of the nostrils on both sides of the nasal cavity, where several pairs of blood vessels meet, especially in the anterior and lower part of the nasal septum, there is a small area called the nasal vestibule, the small blood vessels in the nasal vestibule are densely networked, protected by a very delicate mucous membrane, so the small blood vessels are easy to rupture and bleed. When the amount of bleeding is small, the blood drips out in a punctate pattern, and when the blood is high, the blood spurts out in a columnar shape.

There are several factors that usually trigger nosebleeds:

1. The climate is dry. The nasal mucosa likes to be moist and avoid dryness, whether it is in the autumn season or in the cold wax moon season, as long as the indoor and outdoor climate is dry, it is easy to cause nosebleeds.

2. Fever. When the fever is warm, the heart rate increases, the blood flow rate is fast, the small blood vessels are dilated, and the water intake is less and the sweating is more, and the nose is easy to bleed in the case of dry mouth.

3. Trauma. Picking the nostrils with your hands injures the nasal mucosa, causing blood vessels to rupture; Nasal trauma such as falls and bruises; a foreign body in the nasal cavity; Or sometimes external forces such as coughing, sneezing, and blowing your nose can damage the nasal mucosa and cause nosebleeds. Therefore, nosebleeds should be prevented by targeting the precipitating cause.

What should I do if I have nosebleeds?

1. First of all, sedate, immediately use the thumb and index finger to pinch the wings of both sides of the nose towards the nasal septum and then compress to stop the bleeding.

2. Tilt your head forward, open your mouth to breathe downward, or lie down with your head up. Never raise your head up, as this will cause the blood to swallow down your stomach, and if you vomit too much, it will be mistaken for vomiting blood.

3. Soak a towel in cold water and apply it to the root of the nose to make the blood vessels constrict and stop bleeding when cold.

4. Plug the bleeding site with sterilized cotton, gauze or toilet paper to compress the ruptured blood vessel to stop bleeding. If the bleeding does not stop after the blockage, or the blood comes out of the mouth through the pharynx, you should go to the emergency department of the hospital immediately.

In addition, it should also be noted that frequent nose bleeding may be a local problem of the nose or a manifestation of a certain disease, so students who often have nose bleeding should go to the hospital for further examination to avoid delaying the condition.

1。The nose will be more likely to break after it has been broken once recently, because the capillaries are more fragile, so don't always touch him.

2。It may also be a manifestation of a weak constitution or a complication of other diseases, and it is broken if you don't touch it.

3。And then the air is too dry...

If it is bleeding after touching him, there is generally no major problem, but it is recommended to go to the hospital to check it out if you have time.

Hope it helps.

It is best to check the blood routine to see if the platelets and other blood cells are normal, if they are normal, that is, the nasal cavity is rich in capillaries, and there will be frequent nosebleeds.

There are many causes of nosebleeds, including the nose itself, such as a deviated septum, telangiectasia and rupture, hemorrhagic nasal polyps, and blood diseases.

Frequent nose bleeding is mainly seen in the following situations, the first is caused by erosion or rupture of the nasal mucosa, which is related to frequent nose picking or vigorous nose blowing, and is related to the dryness of the nasal mucosa. The second is what grows in the nasal cavity, such as what grows in the nasopharynx, and the third is blood clotting disorders. Generally, the nasopharyngoscope is examined to see what is going on in the nasal cavity, and then the blood routine and coagulation items can be tested to rule out blood diseases.
