Why is one side of my nose more congested than the other, and what should I do about it?

One side of the nose may have stronger breathing than the other due to physiological nasal septal deviation, unilateral nasal foreign body, acute rhinitis, allergic rhinitis, nasal polyps, or other causes. Depending on the specific situation, improvements can be made through general management, medication, or surgical treatment. The details are as follows:

1. Physiological Nasal Septal Deviation

Most people do not have a perfectly centered nasal septum. A slight deviation can cause one nasal passage to be slightly narrower, obstructing airflow and resulting in differences in breathing strength. If there is no significant discomfort, no special treatment is required. Avoid digging the nose forcefully in daily life to prevent nasal mucosal injury and worsening nasal congestion.

2. Unilateral Nasal Foreign Body

In children or accidental situations, a foreign object may enter one side of the nasal cavity and block the passage, leading to reduced breathing on that side. Do not attempt to remove it yourself; seek medical attention promptly. A doctor will use specialized instruments under illumination to extract the object, followed by rinsing the nasal cavity with saline solution.

3. Acute Rhinitis

Viral infection causes nasal mucosal congestion and swelling. If swelling is more pronounced on one side, it leads to narrowing of that nasal passage. Under medical guidance, ephedrine hydrochloride nasal drops, Lianhua Qingwen capsules, or compound paracetamol and amantadine tablets may be used. Drink plenty of warm water and ensure adequate rest to promote recovery.

4. Allergic Rhinitis

After exposure to allergens, one side of the nasal mucosa may react more intensely, causing edema and increased secretions that obstruct airflow. Under medical guidance, levocetirizine hydrochloride oral solution, montelukast sodium chewable tablets, and budesonide nasal spray can be used. At the same time, avoid allergens such as pollen and dust mites.

5. Nasal Polyps

A polyp formed by hyperplasia of the mucosa in one nasal cavity occupies space and reduces breathing, often accompanied by decreased sense of smell. Under medical guidance, prednisolone tablets, cefaclor sustained-release tablets, and eucalyptus citronellal enteric soft capsules may be taken. If medications are ineffective, endoscopic nasal polypectomy may be performed.

In daily life, maintain nasal hygiene and avoid exposure to irritant gases and allergens. If breathing asymmetry persists or is accompanied by symptoms such as headache or blood-tinged nasal discharge, seek timely medical evaluation to identify the underlying cause. Early intervention helps prevent symptom progression and negative impacts on quality of life.
