What causes nose bleeding in summer?

Nosebleed is a common phenomenon in summer. Nosebleed is also called nosebleed. There are many reasons for nosebleed. Heat, nasal polyps, etc. can cause nosebleed. Generally, if it is a small amount of bleeding, you don’t need to go to the hospital for treatment. If it is a large amount of bleeding, it is best to go to the hospital to find out the cause and use medication under the guidance of a doctor. Don’t take medication blindly to avoid aggravating the condition.

What should I do if I often have nosebleeds in summer?

Provide appropriate treatment based on the condition and cause of nosebleed. For small amounts of bleeding, ephedrine nasal drops can be applied topically. Or apply chloramphenicol eye ointment to the mucosal erosion. When the above methods are ineffective, nasal packing is mostly used. Vaseline gauze, expandable sponges, and hemostatic gauze are often used to pack the anterior nostril. When there is bleeding from the posterior nostril, the posterior nasal packing method is sometimes used. This causes great pain to the patient and may cause abrasions and erosions of the nasal mucosa, affecting the patient's eating and sleeping. In the elderly and patients with myocardial disease, their oxygen saturation may decrease at night, which may induce myocardial infarction and cerebrovascular accident.

Endoscopic microwave coagulation is used to treat nosebleeds. The clear field of view and illumination of the nasal endoscope can be used to observe hidden and difficult-to-detect bleeding sites such as the olfactory groove, the sphenopalatine artery blood supply area at the posterior end of the middle turbinate, the posterior segment of the nasal septum, the posterior end of the inferior turbinate and the top of the nasopharynx. Microwaves are a high-frequency electromagnetic wave that can instantly generate high temperatures in tissues, achieving the purpose of coagulation and hemostasis. Microwave probes of different shapes are used to accurately cauterize and stop bleeding at the bleeding site. The operation is flexible and the hemostasis is reliable. It can minimize the damage to the surrounding normal tissues. Compared with laser, it has the characteristics of no carbonization and no smoke formation. The most important thing is that there is no need for nasal packing after surgery, which reduces the pain of patients. It is a rapid, accurate, effective and safe method of stopping bleeding.

What causes nosebleeds?

1. Traumatic: due to local mechanical injury, such as nose picking, nose lifting, nasogastric feeding, foreign objects in the nasal cavity, etc. Skull base fracture causing internal carotid artery rupture, surgical trauma, such as maxillary sinus lavage, nasal biopsy, turbinate surgery, etc.

2. Inflammatory: acute rhinitis, acute sinusitis, dry rhinitis, atrophic rhinitis, erosion of the nasal septum membrane, stimulation of harmful chemical gases and specific infections, such as diphtheria.

3. From the perspective of traditional Chinese medicine, the causes of nosebleeds can be divided into two categories: dryness and heat and weakness. If you have frequent nosebleeds and also suffer from nasal allergies, with yellow or green nasal discharge, or if your lips are often red and you have bad breath, then you are very hot. First of all, of course, you need to clear away heat. More importantly, you should not eat too much delicious food on a daily basis. Snacks such as chocolate, cookies, French chips, etc. are also very heaty and should be eaten as little as possible.

4. Poisoning by chemicals and drugs: poisoning by phosphorus, mercury, arsenic, benzene, etc. can destroy the function of the hematopoietic system and cause epistaxis. Long-term use of salicylic acid drugs can lead to a decrease in prothrombin and easy bleeding.

5. Endocrine disorders: Compensatory menstruation and premonitory nosebleeds often occur during puberty, mostly due to a decrease in estrogen levels in the blood and dilation of blood vessels in the nasal mucosa.
