What causes a smelly nose?

In daily life, we are often troubled by some nasal diseases. Sometimes we feel that there is a bad smell in our nose. There are many reasons for the bad smell in the nose, which may be rhinitis, nasal polyps, atrophic rhinitis, etc. If you find that your nose has a bad smell, you can first take logistic treatment methods, you can wash it with salt water first, and if the condition is serious, you can take medication.

Symptoms and treatment of rhinitis 1. Acute rhinitis: caused by acute infection, commonly known as "cold" or "flu", may have systemic symptoms. The main symptoms are nasal congestion and increased secretions. In the early stage, the nasal discharge is clear water, which later turns into mucopurulent nasal discharge. The patient may have a low fever and general discomfort. 2. Chronic rhinitis: Develops from acute rhinitis and is related to combined bacterial secondary infection, incomplete treatment and repeated attacks. The main symptoms are nasal congestion, which may be intermittent or alternating in mild cases and persistent in severe cases, with increased nasal secretions. Severe cases require surgical treatment.

3. Allergic rhinitis: Symptoms include sudden itchy nose, sneezing, clear runny nose, nasal congestion, and repeated attacks. Those who suffer from the disease all year round are called perennial allergic rhinitis, and those who suffer from the disease only in fixed seasons are called seasonal allergic rhinitis. When allergic rhinitis occurs, the nasal mucosa may become pale and edematous, and a large amount of clear nasal mucus may remain in the nose. 4. Chronic hypertrophic rhinitis: It comes from chronic simple rhinitis and is caused by long-term chronic inflammation and congestion, which leads to hyperplasia of nasal mucosa and nasal concha.

5. Atrophic rhinitis: It is mainly caused by atrophy of the nasal mucosa, periosteum and turbinate bones. Due to the atrophy of nasal tissue, although the nasal cavity is relatively wide, the nasal mucosa loses its normal physiological function, and due to the formation of dryness in the nose, the patient still feels poor ventilation. When there is a bacterial infection, its toxins and excrement produce a foul odor. 6. Cheesy rhinitis: a rare nasal disease. The clinical features are accumulation of cheesy material in the nose with a foul odor, which erodes soft tissue and bone over time and causes internal and external nasal deformities. Desquamated epithelium, necrotic tissue, purulent cells, cholesterol crystals and mold-like microorganisms were found in the caseous substance.
