What is the reason for bloody nose when sneezing?

Sneezing is a sign of nasal irritation or a cold. If your nose bleeds when you sneeze, it may be caused by getting inflamed or suffering from rhinitis. Sneezing can easily irritate the capillaries in the nasal cavity, causing them to rupture and cause bleeding in the nose. It requires timely examination and treatment, and you should avoid eating irritating foods.

What causes a bloody nose when sneezing?

It is caused by a cold, accompanied by nasal congestion and yellowish sticky nasal discharge.

Acute nasal mucositis is considered to be more likely. Yellow, sticky nasal discharge indicates a viral infection. After a cold, the nasal mucosa becomes congested, and frequent nose blowing can easily lead to the disease. It is recommended to avoid spicy and irritating foods, try not to blow your nose hard, and apply erythromycin ointment on the surface of the nasal mucosa. If necessary, you can go to a regular hospital for examination.

Caused by rhinitis, with clear nasal discharge. Love to sneeze.

After rhinitis occurs, it often lasts for a long time. For several weeks or even longer, you will have clear nasal discharge and your nasal cavity will be very dry. You may not think that clear nasal discharge will moisten your nasal cavity. The actual situation is that the more mucus you have, the drier your nasal cavity becomes. If you look under a strong light, you can see that the inside of the nasal cavity is cracked and bleeding, and the capillaries are ruptured.

This situation is also common in allergic rhinitis. You have to avoid allergens.

Deviated nasal septum

Trauma is the most common cause of nasal septum deviation. When a nasal bone fracture occurs due to trauma, the septal cartilage is often dislocated and deformed, or even fractured. If not repositioned in time, a deviated septum may remain. A narrow birth canal during birth or improper forceps clamping may also cause the septal cartilage to deviate or dislocate.

A bent nasal septum can easily cause rhinitis. This can lead to nosebleeds easily.

Eat a light diet, do not pick your nose with your hands, and avoid strenuous exercise if your nose feels dry and burning. Drink plenty of water and use peppermint oil to moisturize your nose to keep it clear and hygienic.

Other causes

Rhinitis is an inflammatory disease of the nasal cavity. It is an inflammation of the nasal mucosa caused by viruses, bacteria, allergens, various physical and chemical factors, and certain systemic diseases. The main pathological changes of rhinitis are congestion, swelling, exudation, hyperplasia, atrophy or necrosis of the nasal mucosa.

Common causes

Viral infection as the primary cause, or secondary bacterial infection on this basis

Common symptoms

Symptoms such as nasal congestion, excessive mucus, decreased sense of smell, headache, dizziness, etc.

Causes

1. Viral infection

Viral infection is the primary cause, or bacterial infection is secondary to viral infection. More than 100 viruses are known to cause this disease, the most common of which is rhinovirus, followed by influenza and parainfluenza viruses, adenovirus, coronavirus, coxsackievirus, and myxovirus and paramyxovirus. The virus is mainly transmitted through inhalation through the respiratory tract, and secondly through entering the body through contaminated objects or food.

2. Genetic factors

People with a family history of allergies are more likely to develop this disease. Most family members of the patients have a history of asthma, urticaria or drug allergy. In the past, such patients were called atopic individuals, whose ability to produce IgE antibodies was higher than that of normal people. However, in recent years, some people have found that there is no significant difference in the incidence rate between twins and the general population.

3. Susceptibility of nasal mucosa

Susceptibility arises from frequent stimulation by antigenic substances, but the degree of susceptibility depends on the number of mast cells and alkaliphils in the nasal mucosal tissue and the ability to release chemical mediators. It has been confirmed that the number of the above-mentioned cells in the nasal mucosa of patients with allergic rhinitis is not only higher than that of normal people, but also has a stronger ability to release chemical mediators.

4. Antigenic substances

Antigen substances that stimulate the body to produce IgE antibodies are called allergens. When the allergen enters the nasal mucosa again, it combines with the corresponding IgE and causes an allergic reaction. The allergens that cause this disease are divided into two categories according to the way they enter the human body: inhalation and food.
