What is the cause of rhinitis?

Rhinitis is a common ENT disease, the current increase in rhinitis, age also tend to younger age. Also affected the patient's normal work and rest. So what is the cause of rhinitis? See the following description.
(A) genetic factors have metamorphosis family history susceptible to the disease. Patient family with more asthma, urticaria or drug allergy history. In the past, this patient is an atopic individual, and its ability to produce IgE antibodies in vivo is higher than that of normal subjects. But in recent years, the authors found that there was no significant difference between the twin and the general population.
(2) susceptibility to nasal mucosal susceptibility originated from the frequent stimulation of antigenic substances, but the degree of susceptibility is like the number of mast cells in the nasal mucosa, the number of basophils and the ability to release chemical media. It has been confirmed that the number of cells in the nasal mucosa of patients with allergic rhinitis is not only higher than normal, but also has a strong ability to release chemical mediators.
(C) the antigen material to stimulate the body to produce IgE antibody antigen known as the allergen. The allergen material into the nasal mucosa again with the corresponding IgE and cause allergic reactions.
Cause the disease of the allergen according to its way into the human body is divided into two categories of inhalation and food:
1. Inhalation allergen is inhaled into the nasal cavity by breathing. Such allergens are mostly suspended in the air.
(1) pollen is not all plant pollen can cause disease. Only pollen that has a large amount of pollen, a wide vegetation area, a large allergen and is spread by the wind is most likely to become an allergen. Due to the differences in vegetation varieties, pollen with allergenicity in different areas is also different.
(2) fungi are widely distributed in nature, mainly in soil and corrupt organic matter. The mycelium and spores are allergenic, but with strong spores.
(3) house dust mite arthropod door spider gang. Adult size is generally 300 ~ 500μm. Mainly parasitic in every corner of the room, which mattresses, pillows, sofa mats, etc. in the most dust. Mite excrement, eggs, scaling and its broken body, can become allergens.
(4) animal dander animal dander is one of the strongest allergens. Sensitive individuals can be sensitized if they are exposed to the animals for a long time. After re-exposure, even if a small amount of dander, but also to stimulate the nose symptoms.
(5) indoor dust is caused by perennial rhinitis one of the common allergen substances. Its composition is quite complex, is a variety of substances hodgepodge, including animal, plant and chemical and other substances.
2. Intestine allergen refers to the digestive tract into the human body caused by nasal symptoms of allergen substances. Its role in the nasal mucosa is very complex, it is still not clear, milk, eggs, fish, meat, fruit, and even some vegetables, can become allergens.
Warm reminder: suffering from rhinitis friends in the diet should pay attention to, diet should be light, do not eat spicy food, adhere to physical exercise, enhance physical resistance, develop good habits. Finally wish the majority of patients recover soon!
