What are the causes of rhinitis?

Part of the cause of disease
Acute rhinitis recurrent attack or treatment is not complete, and evolved into chronic rhinitis.
1. because of the nearby long-term stimulation or chronic inflammation caused by nasal deformity, occurrence of poor ventilation or drainage obstruction, such as chronic sinusitis, nasal septum, chronic tonsillitis and adenoid hypertrophy.
2., nasal medication inappropriate or excessive excessive formation of drug rhinitis, common in long after use of nose drops.
Two, systemic cause of disease
1. chronic chronic diseases, such as endocrine disorders, long-term constipation, kidney disease and cardiovascular disease, and so on, leading to long-term or repeated nasal congestion or blood stasis.
2. vitamin deficiencies, such as vitamin A or C.
3. excessive smoking and drinking can affect the nasal mucosa vascular relaxation and obstruction.
4., long-term use of blood, equal antihypertensive drugs, can cause nasal telangiectasia and produce rhinitis like symptoms.
5. endocrine diseases or disorders: such as hypothyroidism can cause edema of the nasal mucosa. Late pregnancy and puberty, nasal mucosa often has physiological hyperemia and swelling.
Three, environmental factors
In the environment of cement, tobacco, coal dust, flour or chemicals, the mucous membrane of the nose is stimulated and damaged by physical and chemical factors, which can cause chronic rhinitis. In the environment of rapid change of temperature and humidity, workshop workers, such as steel-making, freezing, drying and melting, are more likely to develop the disease.
