Allergic rhinitis is often referred to as “allergic rhinitis”, but allergic rhinitis cannot simply be equated with allergic rhinitis. Allergic rhinitis includes both allergic rhinitis and those caused by non-immunologic mechanisms (e.g., vasomotor rhinitis). Allergic rhinitis is a generalized term that includes both immunological and non-immunological mechanisms mediating nasal mucosal hyperresponsive rhinopathy. Allergic rhinitis is a chronic inflammation of the nasal mucosa, mainly mediated by immunoglobulin E (IgE), with episodes of sneezing, runny nose, and nasal congestion as the main symptoms after exposure to allergens in susceptible individuals, and it can be categorized into seasonal allergic rhinitis and perennial allergic rhinitis. Allergic rhinitis, related to genetic and environmental factors, is mostly triggered by contact with dust mites, animal hair, pollen, etc. Clinically, there are often symptoms such as nasal itching, sneezing, runny nose, swelling of nasal mucosa and nasal congestion. The first step in treatment is to stay away from allergens and avoid aggravating the condition by re-exposure to allergens. For more serious symptoms can be symptomatic treatment through the use of loratadine, budesonide nasal spray and other drugs. In addition, allergen-specific immunotherapy can also be carried out, and for some patients who are not satisfied with the effect of drugs and immunotherapy, surgical treatment can be carried out. It is recommended that patients suffering from allergic rhinitis seek medical treatment and be guided by a doctor according to their condition, and strictly follow the doctor’s instructions when using medication.
