What causes nasal congestion?

Nasal congestion usually refers to a stuffy nose. In general, nasal congestion may be caused by foreign bodies in the nasal cavity, upper respiratory tract infections, sinusitis, deviated nasal septum, adenoid hypertrophy, or other reasons. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment accordingly. Specific analyses are as follows:

1. Foreign body in the nasal cavity

When external substances such as dust, pollen, or bacteria enter and remain in the nasal cavity, they may cause nasal congestion. In such cases, patients should promptly go to a正规 hospital for removal of the foreign body.

2. Upper respiratory tract infection

Viral or bacterial infections can lead to inflammation of the nasal mucosa, resulting in increased mucus secretion, nasal mucosal congestion, and swelling, thereby causing nasal blockage. Patients may take medications such as Compound Liquorice Tablets, Lianhua Qingwen Capsules, or Ganmao Ling Granules as directed by a physician to alleviate symptoms.

3. Sinusitis

Sinusitis refers to infection and inflammation of the mucous membranes within the sinuses, which may be caused by bacteria, viruses, or fungi. Sinusitis can cause the sinuses to fill with secretions, blocking nasal passages and leading to nasal congestion. Patients may be treated under medical guidance with medications such as Biyuan Tongqiao Granules, Cefixime Capsules, or Tongqiao Biyan Pills.

4. Deviated nasal septum

A deviated nasal septum refers to an abnormal shape of the nasal septum, which may result from congenital factors or trauma. This deviation causes asymmetry in the nasal passages, obstructing airflow and leading to a sensation of nasal congestion. Treatment options under medical guidance include partial septal resection, three-line tension-reducing procedure, or septoplasty.

5. Adenoid hypertrophy

Adenoids are lymphatic tissues located in the nasopharynx. When stimulated by infection or allergies, the adenoids may enlarge and block the nasal passages, causing the aforementioned symptoms. It is recommended that patients promptly seek treatment at a正规 hospital through procedures such as adenoid curettage, adenoidectomy, or endoscopic adenoid ablation.

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