Why does the nose bleed when the nose is strained?

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.

Rhinitis tablets. It seems to have been produced by a pharmaceutical factory in Wuhan.

Other rhinitis tablets of the same kind are not very good.

It is recommended to go to a regular hospital for a detailed examination to rule out fire, nasal mucosal damage, nasal septum deviation, nasal inflammation, foreign body, etc., according to the doctor's instructions for conditioning and medication, do not pick your nose with your hands, drink more water, and the indoor temperature and humidity are appropriate.

Analysis: Hello, nosebleeds are caused by the damage of the mucosa in the Li area of the nasal vestibule, because this small area is rich in blood vessels, and once it is broken, nosebleeds will occur. Of course, if you have frequent nosebleeds, you still need to have a detailed examination.

Opinions and suggestions: 1. First of all, to rule out the cause of local diseases, you need to look at the ENT department, and rule out the nasal septum deviation, nasal polyps, tumors, rhinitis, etc.

2. It is necessary to exclude the blood system, thrombocytopenia, leukemia, etc., which can be checked through blood routine or bone puncture.

3. Of course, if there is occasional nosebleeds, the problem is not big, the more common is the bleeding caused by the rupture of the nasal mucosa, usually people say "on fire" has a relationship, the nasal mucosa is congested, dry leads to ulceration and bleeding. Pay attention to drink plenty of water, eat more fruits, and use paraffin oil and glycerin nasal drops when the nasal passages are dry.

Don't keep deducting how many sides I have to say.

The causes of nosebleeds fall into two categories, local causes and systemic causes.

Local causes:1Nasal trauma: The nasal septum mucosa is very thin and rich in blood vessels, and once traumatized, bleeding is very likely to occur.

Heavy nose picking, sneezing vigorously or blowing your nose vigorously can also be a cause of nasal trauma. In addition, nasal foreign bodies and deviated septum can also cause nosebleeds. 2.

Nasal tumors: Tumors in the sinuses or nasopharynx often have new blood vessels and are prone to bleeding. The tumor compresses nearby tissues, destroying them and may cause secondary infection, which can cause bleeding.

Cancers of the sinuses or nasopharynx often present with blood in the runny nose, while nasopharyngeal angiofibromas can bleed profusely and repeatedly. 3.Nasal inflammation:

Acute rhinitis, acute (slow) sinusitis, atrophic rhinitis, etc., can cause nasal vasodilation or nasal mucosal erosion, resulting in bleeding.

The systemic causes are roughly as follows:

1.Middle-aged and elderly people with high blood pressure and arteriosclerosis are prone to rupture of blood vessels in all parts. The rupture of blood vessels at the back of the nose or the top of the nose in the front of the nasal cavity causes severe bleeding and is not easy to stop.

2.Elderly patients with chronic bronchitis, emphysema or cor pulmonale can cause nasal mucosal variceal bleeding due to left heart hypertrophy and increased venous blood pressure. If tumors of the chest and mediastinum develop and compress the heart, they can also cause increased venous pressure and nasal venous bleeding.

3.Certain infectious diseases, such as influenza, hemorrhagic fever and typhoid, can cause nosebleeds. 4.

Thrombocytopenic purpura, aplastic anemia and leukemia can also cause nosebleeds. 5.Chronic diseases such as cirrhosis, chronic nephritis, or rheumatic fever often cause blood clotting disorders or damage to small blood vessels, which can cause nosebleeds.

6.Nosebleeds are also predisposed to due to malnutrition or lack of vitamins C, K, P or calcium.

You are bleeding in the Li area, it is easy to bleed when the weather is dry, don't pick your nose, if you want to solve the problem fundamentally, go to the hospital to do a microwave** burn the blood vessels, and it won't bleed And**It's not expensive, we charge about 100 yuan here.

There are many reasons why the nose bleeds at the slightest touch. There is a blood disorder, or the nasal mucosa is too dry and easy to rupture.

Suggestions: You can take some oral drugs to cool blood and stop bleeding or nourish yin and lower gunpowder, Yiqing granules or Xuanmai sweet orange granules. It's best to supplement with some vitamin C.

The nasal cavity can be lubricated with erythromycin eye ointment or vitamin AD drops. If the symptoms are still not relieved, it is recommended to go to the hospital for a blood test. In order to be symptomatic**.

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

Nosebleeds are a very common symptom.

But the personal situation is different, for example, my family seems to be familial, when I was a child, the weather was hot, and if I was accidentally touched, or blew my nose, I would bleed. But when I became an adult, I got better. Like your words, your question is very simple, no more description, do not know the age, the specific situation, cannot assert.
