Rhinitis (r. rhinitis) is inflammation of the nasal mucosa. Rhinitis is classified according to etiology, mechanism of development, course, severity, and also depending on the nature of changes in the mucous membrane, taking into account the nature and degree of its swelling (inflammation), the presence or absence of exudate, as well as the prevailing morphological changes. Based on the nature of inflammation, rhinitis is distinguished as catarrhal (simple), hypertrophic (granular), atrophic (dry), atrophic-hypertrophic. Depending on the cause, infectious, allergic, and non-infectious rhinitis are distinguished. According to the severity of the course, rhinitis is divided into acute, subacute, chronic and vasomotor. Chronic rhinitis can occur in various forms, which, in turn, also have different degrees of severity. In most cases, chronic rhinitis occurs in waves. Its exacerbations can last for several months in a row, then gradually subside and worsen again. This process is cyclical and lasts many years. Exacerbations of chronic rhinitis are possible at any time of the year. As a rule, they occur due to a decrease in the body's resistance to infection, hypovitaminosis, hypothermia, or exposure to an allergen on the nasal mucosa.
Atrophic rhinitis is a chronic disease characterized by inflammation and hardening of the nasal mucosa. Most often occurs in old age, especially in men. If left untreated, it can lead to the development of complications such as nasal sinusitis or chronic pharyngitis. In some cases, rhinitis can last for years without significant symptoms.
