Is a stuffy nose caused by a cold? These factors can also cause a stuffy nose

Once the symptoms of nasal congestion appear, I believe many people will first think of a cold. Indeed, one of the main symptoms of a cold is nasal congestion. However, medical experts point out that the symptoms of nasal congestion are not necessarily caused by a cold. The following factors may induce nasal congestion symptoms, and netizens need to pay more attention.

1. Adverse environmental stimulation

About one-third of patients with nasal congestion have nasal inflammation that is not caused by allergies. Dr. Gerald B. Lee, professor of pediatrics at the University of Louisville, said that if the allergen test is negative, your nasal congestion may be due to non-allergic rhinitis.

Vasomotor rhinitis is a very common non-allergic rhinitis caused by irritation from cigarette smoke, perfume or dry air. Temperature fluctuations may also cause nasal congestion.

Relief methods:

It is recommended to stay away from the source of the disease. If this is ineffective, you can use decongestants or nasal sprays containing antihistamines and corticosteroids under the guidance of a doctor.

2. Drug dependence

Decongestant nasal sprays (such as oxymetazoline) often work wonders for allergies and colds, but they should not be used continuously for more than 3 days. Excessive use of medication can lead to "rebound nasal congestion," or drug dependence. When you want to stop taking the medication, the nasal congestion will return or even worsen, resulting in continued medication use, and a vicious cycle.

Relief methods:

Although it is painful, you should work to stop being addicted to the drug. If this is difficult to do on your own, you can seek help from your doctor. Oral or nasal steroids may also help.
