Why is there a sudden nosebleed? What is the reason?

There are many people with nosebleeds, but most people don't care why they have nosebleeds after they stop. Otolaryngology experts pointed out that although most nosebleeds are not serious, there are still some systemic diseases that are symptoms of nosebleeds. Although the probability is low, we should pay attention to it. So what is the reason for frequent nosebleeds?

1. The causes of nosebleeds can be divided into two categories: heat and weakness. If you often have nosebleeds, you also suffer from nasal sensitivity, yellow or green runny nose, or your lips are often red and smelly, which is very hot. First of all, of course, we must clear away heat. More importantly, we shouldn't eat too much delicious food on weekdays. Snacks such as chocolate, cookies and French fries are also very hot and dry. Try to eat as little as possible.

2, due to local mechanical injuries, such as nose digging, nose lifting, nasal feeding, nasal foreign bodies, etc. Fracture of skull base leads to rupture of internal carotid artery (nosebleed passes through the channel). Surgical trauma, such as maxillary sinus puncture, nasal biopsy, turbinate surgery, etc.

3, acute rhinitis, acute sinusitis, rhinitis sicca, atrophic rhinitis, nasal septum erosion, the stimulation of harmful chemical gases and specific infections, such as diphtheria. Hemorrhagic necrotizing nasal polyp is a hemorrhagic disease similar to malignant tumor. Pathological examination can confirm the diagnosis.

4. Frequent nosebleeds are complications of cardiovascular system, internal organs, various infections, blood diseases and other diseases. A child's nosebleed is usually a sign of influenza and acute respiratory diseases. If purulent discharge of nose precedes epistaxis, then foreign body may be the main cause.

5, because the child's nasal mucosa is delicate and fragile, and the air is dry in spring and summer, it is easy to cause nasal mucosa capillaries to rupture and nosebleeds; Because some children have the bad habit of picking the nasal cavity, when picking the nasal cavity for a long time, it is easy to cause nasal inflammation, which will cause congestion, edema or bleeding of the nasal mucosa.

Pay attention to the diet structure, eat less spicy food and eat more foods containing vitamins C and E, such as vegetables, cucumbers and tomatoes. Apples, mangoes, peaches and other fruits; And beans, eggs, dairy products and other foods to consolidate the blood vessel wall, enhance the elasticity of blood vessels, and prevent the occurrence of rupture and bleeding.
