What causes nasal congestion?

In general, nasal congestion may be caused by inadequate nasal hygiene, foreign objects in the nasal cavity, nasal trauma, upper respiratory tract infections, or sinusitis. Patients should seek timely medical attention at a正规 hospital and receive appropriate treatment based on the specific condition. The detailed analysis is as follows:

1. Inadequate Nasal Hygiene

If nasal cleaning is incomplete, accumulated secretions, dust, bacteria, or other impurities inside the nostrils may lead to nasal blockage. These substances can obstruct the nasal passages, restrict airflow, and cause a sensation of congestion. It is recommended that patients use a cotton swab moistened with warm water to gently clean the nasal cavity, followed by rinsing with normal saline to maintain nasal hygiene.

2. Foreign Objects in the Nasal Cavity

Sometimes, foreign bodies such as small particles or insects may enter the nasal cavity. These objects can block the nasal passage and result in nasal obstruction. In children, small toys or food items may be inserted into the nose, leading to blockage symptoms. When a foreign body is suspected, prompt medical evaluation is necessary. Under a doctor's guidance, the object should be promptly removed using tweezers.

3. Nasal Trauma

Nasal injuries, such as from impact or falls, may cause nasal bone fractures, nasal swelling, or damage to the nasal mucosa. Such injuries can narrow or obstruct the nasal passages, resulting in nasal congestion. Applying a warm towel to the bridge of the nose may help relieve pressure and reduce mucosal swelling.

4. Upper Respiratory Tract Infection

Viral invasion of the nasal mucosa can cause local congestion, edema, and increased secretions. These pathological changes may block the nasal passages and impair breathing. Under medical guidance, patients may use medications such as acetaminophen tablets, ibuprofen tablets, or compound licorice tablets for treatment.

5. Sinusitis

Sinusitis is an inflammatory condition of the sinuses, which may be triggered by infection, allergies, or structural abnormalities in the nasal cavity. Inflammation leads to mucosal swelling and increased secretions within the sinuses, causing nasal obstruction and related symptoms. Patients may take medications such as Biyan Tongqiao Granules, Cefixime Capsules, or Tongqiao Biyan Tablets orally as directed by a physician.

In daily life, it is recommended to maintain a positive mindset, avoid spicy, stimulating, and greasy foods, get adequate rest, and develop healthy lifestyle habits.
