In daily life, how many of us have encountered a "nosebleed" situation, then there are always people concerned to tell the nosebleed people: "quickly raise the other side of the arm", "look up", "put toilet paper into the nostrils"...

Experts say these approaches are wrong. What's more, nosebleeds are sometimes not small events, but one of the early manifestations of many diseases.

Both systemic and local diseases can cause epistaxis

Nosebleed is a very common symptom of otolaryngology, which can be manifested as nasal bleeding on one side, or nasal bleeding on both sides, and the degree of bleeding is also different.

Some patients blow their nose with blood or after sucking their nose with blood, some will bleed heavily, and may even lead to hemorrhagic shock.

Most of the bleeding sites in children and adolescents are in the nose, and there are rich capillaries clustered under the mucosa at the most front of the nasal septum, while adults and the elderly are more common in the back of the nasal cavity, which is relatively troublesome to deal with.

The causes of epistaxis are very complex, including both systemic and local, and many times, epistaxis is a manifestation of the disease.

Among them, systemic diseases include: hypertension, arteriosclerosis, more common in the elderly, due to the increase of blood vessel fragility in the body leads to easy bleeding in the nose; Leukemia, aplastic anemia, hemophilia and other blood system diseases; Long-term use of anticoagulant drugs, such as patients after stent surgery, the coagulation mechanism is damaged to a certain extent; Nutrition is not balanced, usually less intake of vitamins; Chronic diseases such as liver and kidney dysfunction.

Local causes include nasal trauma, allergic rhinitis, acute and chronic sinusitis, deviated nasal septum, nasal cavity, sinuses and nasopharyngeal tumors, etc. For example, one of the early symptoms of nasopharyngeal cancer is the blood in the nasal discharge after the patient.

Lifting your head or arms can't stop a nosebleed

The specific treatment of nosebleed should be determined according to the amount and frequency of bleeding. In this regard, if it is only occasional nasal bleeding, the amount of bleeding is small, easy to stop, and is not accompanied by other symptoms, then everyone can handle it at home.

For common anterior nasal bleeding, compression is the simplest way to stop bleeding, that is, the finger will be the bleeding side of the nose to the septum, a few minutes after the basic natural hemostasis.

If you have a medical cotton ball at home, you can plug the cotton ball on the bleeding side to achieve the purpose of pressing the bleeding point.

However, it is not recommended that you use toilet paper and other items to block the nostrils, on the one hand, the degree of hygiene is difficult to guarantee, may bring infection and other problems; On the other hand, the nasal mucosa may be secondary damaged by tearing.

However, if the amount of blood loss is large, it is likely to be caused by the rupture of the internal artery of the nasal cavity, the amount of blood loss can reach tens of milliliters or even hundreds of milliliters, and not timely hemostasis will even cause hemorrhagic shock and other serious consequences, the need to go to the hospital in time, by a professional doctor to stop bleeding, and further identify the cause, and then symptomatic treatment.

In the same way, if it is repeated bleeding, accompanied by more and more serious nasal congestion symptoms, it is also recommended to go to the hospital as soon as possible.

When there is more nose bleeding, many people think that the head can prevent blood flow, in fact, the head not only does not help to stop bleeding, but also makes the nose bleed flow to the pharynx, is swallowed into the gastrointestinal tract, easy to cause nausea, vomiting and other symptoms, but also affect the doctor's judgment on the amount of blood loss.

In addition, for the practice of elevating the opposite arm, there is no help to stop nosebleeds, and the contraction of the nasal mucosa blood vessels and the elevation of the arm are respectively innervated by different nervous systems, and there is no relationship between the two.

Long-term recurring nasal symptoms should be seen by a doctor

In daily life, especially children, parents should be careful not to let them develop the habit of picking their nose, or blowing their nose hard, rubbing their nose, etc. Our nails may damage the capillaries. When blowing your nose, take turns with one nostril and rinse your nose with water.

At the same time, the usual nutritional intake should be balanced, eat more fresh fruits and vegetables, but litchi, cherry, mango, apricot and other hot fruits do not eat too much.

At the same time, don't eat too much chocolate, lamb, etc.

In a dry climate, keep your nasal passages moist.

For example, spray the nose with physiological sea salt water; You can also use peppermint oil, sesame oil, olive oil and other drops to relieve dry nose; Sprinkle water on the ground, or use a humidifier to increase the humidity of the air; Drink plenty of water.

The most important thing is to seek professional help. Whether it is nosebleed or other nasal symptoms, if it occurs repeatedly for a long time, it is necessary to go to the hospital as soon as possible.
