Why do you get allergic rhinitis? What are the specific reasons?

Rhinitis, also known as allergic rhinitis, is caused by contact with some allergens. In fact, there are many factors that cause allergic rhinitis, such as genetic factors. If you suffer from allergic rhinitis, you must take good care of yourself and stay away from allergens to prevent the onset of rhinitis.

1. Genetic factors People with a family history of allergies are more likely to develop this disease. The causes of rhinitis in patients' families often include a history of asthma, urticaria or drug allergies. In the past, such patients were called atopic individuals, whose ability to produce IgE antibodies was higher than that of normal people. However, in recent years, some authors have found that there is no significant difference in the causes of rhinitis between twins and the general population.

(ii) Susceptibility of nasal mucosa. Susceptibility arises from frequent stimulation by antigenic substances, but the degree of susceptibility depends on the number of mast cells and alkaliphils in the nasal mucosal tissue and the ability to release chemical mediators. It has been confirmed that the number of the above-mentioned cells in the nasal mucosa of patients with allergic rhinitis is not only higher than that of normal people, but also has a stronger ability to release chemical mediators.

(3) Antigenic substances. Antigen substances that stimulate the body to produce IgE antibodies are called allergens. When the allergen enters the nasal mucosa again, it combines with the corresponding IgE and also causes rhinitis.

(1) Not all plant pollen can cause disease. Only those pollens with large amounts, wide vegetation areas, strong allergenicity and spread by wind are most likely to become allergens. Due to differences in vegetation species, the allergenic pollen in different regions is also different.

(2) Fungi are widely distributed in nature, mainly found in soil and decaying organic matter. Both its hyphae and spores are allergenic, but the spores are more allergenic.

(3) House dust mites belong to the class Arthropoda. The size of adults is generally 300 to 500 μm. It mainly parasitizes in various corners of the room, with the most being in the dust in mattresses, pillows, sofa cushions, etc. The excrement, eggs, desquamation and broken body parts of mites can all become allergens.

(4) Animal dander Animal dander is one of the strongest allergens. Susceptible individuals may become sensitized if they come into contact with the relevant animals for a long time. After sensitization, further contact with even a small amount of dandruff can trigger nasal symptoms.

(5) Indoor dust is one of the common allergens that cause perennial rhinitis. Its composition is quite complex, being a hodgepodge of various substances, including animal, plant and chemical substances.

We have introduced the causes of allergic rhinitis to you in detail. We hope that everyone can pay attention to it. In normal times, you need to pay attention to get more rest and carry out comprehensive conditioning to avoid causing serious illness. I hope everyone pays attention to their own living matters and should pay more attention to their own conditioning methods to effectively prevent it.
