Difficulty Breathing Through the Nose – Causes, Symptoms, Diagnosis, and Treatment

1. Septum DeviationThe nasal septum — the inner wall dividing the nasal cavity — can become deviated to one side, often due to trauma. This causes narrowing of one or both nasal passages, making airflow difficult. Deviated septum is very common and often goes unnoticed for years.
2. Turbinate HypertrophyTurbinates are small structures inside the nose that filter and moisten the air. However, due to allergies, chronic inflammation, or hormonal changes, they may enlarge and block airflow.
3. Allergic and Vasomotor RhinitisAllergies to dust, pollen, animal fur, or other allergens cause swelling of the nasal mucosa. Similar symptoms occur with vasomotor rhinitis, when nasal blood vessels overreact to temperature changes, stress, or humidity.
4. Nasal PolypsSoft growths inside the nasal cavity or sinuses — known as polyps — can cause complete nasal blockage. They grow slowly and often remain unnoticed until breathing becomes significantly difficult.
5. Chronic SinusitisLong-term inflammation of the sinuses leads to persistent swelling, mucus buildup, and breathing difficulty. Additional symptoms may include headaches, a feeling of pressure in the forehead or face, and fatigue.
6. Nasal Trauma or Congenital AnomaliesFractures or deformities of the nasal bones can create mechanical obstruction and impair airflow.

Symptoms That Should Not Be Ignored

• Constant or periodic nasal congestion
• Mouth breathing, especially at night
• Snoring and insomnia
• Reduced sense of smell
• Frequent headaches
• Throat dryness or irritation
• Chronic fatigue and oxygen deficiency

These symptoms often become part of a person's routine, so they are ignored — but this is precisely when professional evaluation is most important.

Diagnosis – Identifying the Exact Cause

Modern medicine allows for detailed, painless assessment of the nasal cavity.Endoscopic diagnosisis considered the“gold standard.”Using a special camera, the doctor can clearly visualize the nasal structures, turbinates, polyps, and septum condition. The examination is completely painless and takes only a few minutes.
