The diagnosis of chronic rhinitis should first be differentiated into two categories: allergic rhinitis and non-allergic rhinitis. Diagnostic criteria of allergic rhinitis: positive allergen skin test and positive serum specific IgE test. 1. Allergic rhinitis is also divided into seasonal hay fever and perennial allergic rhinitis. To put it simply, allergic rhinitis is due to a special protein in the blood: specific IgE, which develops once it comes into contact with allergens. Spring pollen, and fall pollen are the most common allergens. Dust mites are the most common culprit of perennial allergic rhinitis. Therefore, seasonal allergic rhinitis cannot be cured because the onset is short and the symptoms can be well controlled with a combination of medications. For perennial allergic rhinitis, desensitization can be done and a 3-year vaccine can be given to some patients; the most commonly used vaccine in China is the standardized vaccine imported from Germany, and only the dust mite vaccine is available; for patients who are not suitable for desensitization, only a combination of medications can be used to control the symptoms. The most commonly used combination medication program is as follows: (1) nasal spray hormone: mometasone furoate nasal spray, fluticasone propionate nasal spray, budesonide nasal spray. (2) Topical antihistamines: nasal spray of azelastine hydrochloride. (3) Oral antihistamines: dirlethadin, roratadine, cetirizine, etc. (4) Oral leukotriene antagonist: montelukast sodium. 2. Non-allergic rhinitis: Diagnostic criteria for non-allergic rhinitis: negative allergen skin test and negative serum specific IgE. The clinical diagnosis of non-allergic rhinitis is very confusing. In fact, in the end, we believe that non-allergic rhinitis is just a state in which your ability to regulate the degree of nasal mucosal congestion does not match the bony structure of your nasal cavity and the thickness of the mucosa, resulting in poor breathing through the nose, snot and sneezing as the main symptoms of discomfort. The degree of nasal mucosal congestion in human body is regulated by the phytoconstriction: sympathetic nerve constricts blood vessels, and parasympathetic nerve diastolic blood vessels. By regulating the degree of nasal mucosal congestion (mainly in the inferior and middle turbinates), the body’s plant nerves regulate the size and distribution of nasal airflow to adapt to different living environments and work scenarios. Once you have problems with your regulation ability (mostly decreasing regulation ability), excessive congestion of the nasal mucosa will lead to poor transnasal breathing, excessive snot, sneezing and other uncomfortable symptoms, and even lead to a feeling of suffocation, headache and other head discomfort symptoms; long-term poor transnasal breathing may even affect mood, personality, psychological state, etc. Treatment of non-allergic rhinitis: (1) Improve your own regulatory ability: various forms of exercise can improve the ability to regulate the plant nerves; however, it is necessary to persevere, at least three months of continuous regular exercise. (2) Topical nasal spray hormone can also be used to rinse the nasal cavity with physiological sea saline to assist in the treatment. (3) If you can’t relieve the discomfort after more than three months of continuous regular exercise plus the local use of nasal spray. It means that your regulatory ability cannot adapt to your nasal structure, so you can only ask your doctor to help you adjust your nasal structure: septal deviation correction, partial removal of the middle and lower turbinates, etc. It’s easy to say, it’s that simple. However, it is easy to say, but the diagnosis and treatment should be very careful.
