Why rhinitis causes asthma

Why rhinitis causes asthma

In recent years, the incidence of rhinitis and asthma has increased year by year, and the correlation between the two has also attracted widespread attention. Research shows that rhinitis and asthma often coexist, and rhinitis may be a precursor or cause of asthma. This article will combine the hot topics and hot content on the Internet in the past 10 days to deeply explore why rhinitis causes asthma and provide structured data support.

1. The relationship between rhinitis and asthma

Rhinitis and asthma are both respiratory diseases and often occur in the same patient. Here are key data on the link between rhinitis and asthma:

2. The mechanism of rhinitis causing asthma

The mechanism by which rhinitis causes asthma is complex and mainly includes the following aspects:

1. Upper respiratory tract-lower respiratory tract linkage of inflammatory response

The nasal mucosa of patients with rhinitis is in a state of inflammation for a long time. Inflammatory factors (such as histamine, leukotrienes, etc.) can affect the lower respiratory tract through blood circulation or nerve reflexes, leading to bronchial mucosal inflammation and airway hyperresponsiveness, thereby inducing asthma.

2. Postnasal drip syndrome

Patients with rhinitis have increased nasal secretions, and part of the secretions will flow back into the throat and trachea, irritating the lower respiratory tract mucosa, causing coughing and bronchospasm, and may develop into asthma in the long term.

3. Nerve reflex mechanism

Inflammatory stimulation of the nasal mucosa can cause bronchoconstriction through the trigeminal nerve reflex. This nerve reflex mechanism is one of the important ways in which rhinitis induces asthma.

The following are hot topics and hot content related to rhinitis and asthma in the past 10 days:

4. How to prevent rhinitis from developing into asthma

For patients with rhinitis, especially those with allergic rhinitis, the following measures can help prevent the occurrence of asthma:

1. Standardize the treatment of rhinitis

Timely use of antihistamines, nasal corticosteroids, etc. to control rhinitis symptoms and reduce the release of inflammatory factors.

2. Avoid allergens

Identify and avoid contact with allergens such as pollen and dust mites to reduce nasal and respiratory irritation.

3. Enhance immunity

Enhance immunity and reduce the risk of respiratory infections through a reasonable diet, moderate exercise and adequate sleep.

4. Regular follow-up

Rhinitis patients should have regular follow-up visits to monitor respiratory symptoms, detect signs of asthma early and intervene promptly.

5. Summary

The relationship between rhinitis and asthma has been widely recognized, and rhinitis patients are a high-risk group for asthma. By understanding the mechanism by which rhinitis causes asthma and taking effective preventive measures, the risk of asthma can be reduced. The public should increase their awareness of the co-morbidities of rhinitis and asthma, seek medical treatment promptly, and standardize treatment to ensure respiratory health.
