Rhinitis may be due to poor resistance, poor resistance is one of the reasons for inducing rhinitis, clinically there are the following analysis: the first, acute rhinitis is mainly due to viral infection, clinically low resistance and poor resistance is one of the reasons for inducing this disease. The defense of the nasal mucosa against viruses is relatively low, leading to viral infection in the nasal cavity, resulting in the manifestation of acute rhinitis, which is clinically manifested as the lack of ventilation in the nose, runny nose, and the patient can have fever, headache, dizziness and other systemic manifestations. The second type, allergic rhinitis and poor resistance may also have a certain relationship, because the patient’s resistance is poor, once contact with allergens will be easy to appear in the nasal cavity after the allergic reaction, resulting in a runny nose, sneezing, itchy nose and other related performance. The third, chronic simple rhinitis and chronic hypertrophic rhinitis, poor resistance and the occurrence of this disease does not have a very direct relationship. It may be related to the patient’s exposure to outside polluted air, inhaling second-hand smoke or changes in temperature and temperature difference, etc. The existence of dry rhinitis and atrophic rhinitis is also not directly related to poor resistance.
