Recurrent episodes of rhinitis in children may be related to allergic factors and adenoid hypertrophy. If there are recurrent symptoms of sneezing, watery nasal discharge and rubbing the tip of the nose, it is caused by allergic factors. Since many allergens cannot be completely isolated, it is easy to have recurrent episodes, and the symptoms can only be effectively controlled by standardized drug treatment. As the body develops and resistance gradually increases, the symptoms may gradually recover. When drug treatment is ineffective, immune desensitization therapy can be chosen. At the same time, should check whether there is a combination of adenoid hypertrophy, because over-enlarged adenoids can block the back of the nasal cavity, affecting the ventilation and drainage of the sinuses and nasal cavity, so that the inflammation can not be effectively recovered, adenoidectomy can reduce the symptoms of rhinitis.
