Why do you get up every morning and have bloody boogers in your nostrils?

On the one hand, the knowledge said by the two people upstairs is truth. There are many other reasons. If you have rhinitis, you will scratch your skin with your fingers because it itches when you sleep. A person who is too hot is too angry. Because of the heat, the skin at the bleeding part of the nose is very thin and easy to crack. Most people's noses are bleeding areas.

Cause of nosebleed: 1, nasal mucosa ulcer, erosion. It is common in the anterior inferior area of nasal septum and is mostly caused by chronic inflammation. Chemical gas, high temperature and dry air may all be the inducement.

2. Acute infection of nose and sinuses.

3. Traumatic nasal trauma causes tearing of nasal mucosa, which can cause nosebleed. Traumatic fractures of nose, forehead, ethmoid sinus and orbit complex are often complicated by rupture of anterior ethmoid artery, which can lead to upper nasal bleeding. Fracture of skull base can rupture internal carotid artery and form traumatic pseudoaneurysm, and nosebleed will be severely punished through sphenoid sinus. If the anterior cranial fossa fracture has the rupture of the anterior cerebral artery, it can cause bleeding at the horizontal plate of ethmoid bone at the top of the nasal cavity.

4. Most of the nosebleeds caused by tumors are caused by the ulceration of tumors themselves, and the degree of bleeding varies with the nature of tumors. Fatal nosebleed can occur when advanced malignant tumor invades large blood vessels.

5. Elevated venous pressure in head and neck can be seen in chronic bronchitis, emphysema, cor pulmonale, congestive heart failure and other diseases. When the patient coughs, the venous pressure in the head and neck increases, which is easy to rupture the semicircular venous plexus at the back of the inferior nasal passage and cause bleeding. Sometimes elderly patients with constipation can also cause nosebleeds.

6. The increase of vascular wall brittleness is seen in arteriosclerosis and vitamin C and K deficiency. The deficiency of vitamins and some rare elements caused by partial eclipse is a common cause of epistaxis in children. In addition, chronic gastrointestinal diseases and liver diseases can cause vitamin deficiency.

7. In patients with hereditary telangiectasia, the junction of endothelial cells between peripheral arterioles and venules is irregularly expanded due to lack of elastic fibers, and the most bleeding part is the vascular plexus in the front of nasal septum.

8. Obstacles of coagulation mechanism Any blood that affects the coagulation mechanism can cause nosebleeds, and sometimes nosebleeds can be the first symptom of these diseases. Common patients are aplastic anemia, leukemia, thrombocytopenic purpura, allergic purpura, hemophilia and so on. Hematology nosebleed is characterized by extensive bleeding sites, often involving the whole body mucosa and skin. Nosebleeds are long-term and repetitive. In addition, liver disease can also cause nosebleeds because it interferes with the synthesis of prothrombin and fibrinogen.

9. Other rheumatic fever, acute febrile infectious diseases (such as typhoid fever and relapsing fever), hyperthyroidism, menstrual nosebleeds, etc. Take a lot of non-steroidal drugs such as aspirin and indomethacin for a long time.

10. Rapid changes in air pressure, such as flying, diving or altitude sickness, can also lead to nosebleeds.

Because you haven't been there long, it may be caused by hot weather or some kind of acute inflammation. If the situation lasts for a long time, I still suggest you go to the hospital for a check-up, otherwise it will be easy to get rhinitis after a long time.
