Overexposed reverse rhinitis, also known as vasomotor rhinitis, can be divided into three clinical types. Physical response type Some patients often produce specific nasal response to certain rational stimuli. For example, every exposure to cold air, sudden temperature changes, humidity, etc., will produce episodes of sneezing, accompanied by a large amount of watery nasal discharge. The patient can often clearly state the cause of the attack. This type may also be a reverse hypertonic rhinitis. Vasomotor rhinitis (vasomotor rhinitis) is a hyperresponsive rhinitis caused by an imbalance in neuroendocrine regulation of the vascular and glandular functions of the nasal mucosa. The pathologic mechanism of this disease is complex and many aspects of the disease are still not well understood, which makes the exact clinical diagnosis and effective treatment difficult. There is no significant gender difference in the onset of the disease, and vasomotor rhinitis rarely occurs in children. Causes of excessive reverse rhinitis: 1, psychological and emotional factors Long-term mental stress, excessive fatigue, emotional fluctuations is the root cause of the disease. If long-term in a high sense of urgency, depression, sense of loss of the environment of living and breathing, resulting in a sharp increase in the incidence of morbidity. 2, external stimuli Climate change, such as temperature, humidity of the sudden change can cause attacks. Sometimes mistaken for seasonal allergic rhinitis. Atmospheric pollution, such as smoke, dust, alcohol and other chemicals can also induce this disease. Getting up, exercise, etc. can also be a trigger. 3.Endocrine factors are common in adolescence, menstruation, pregnancy, menopause and the elderly. Sexual excitement can also cause seizures. Diabetes, arteriosclerosis, hypothyroidism can also cause this disease. 4, the role of drugs Long-term use of blood pressure, lipid-lowering drugs, can cause nasal mucosal edema; abuse of nasal drops caused by drug rhinitis, resulting in autonomic nervous system dysfunction of the nasal mucosa induced the disease. 5.Infection factors before the onset of chronic rhinitis, sinusitis history.
