Allergic rhinitis triggers asthma

Allergic rhinitis is mainly an allergic reaction. It is caused by a specific individual being exposed to some bacteria that can produce a variety of immune cells and can only participate in some chronic inflammatory reactions in the body. It is not a serious disease that can affect the patient's life, study and work efficiency, and cause some heavy economic burdens. It can even induce some bronchial asthma, sinusitis, nasal polyps and otitis media.

The common symptoms of combined conjunctivitis are sneezing, nasal itching, nasal congestion, loss of smell and headache. Examination will reveal some mucosal congestion and other diseases, so you must pay attention to treatment in your daily life.

Allergic rhinitis is often associated with contact allergens. Recent studies have shown that heredity and environment are also important factors in allergic rhinitis.

1. Allergens There are three main ways that allergens act on individuals: ① Inhaled allergens: Indoor allergens mainly include dust mites, animal fur or allergens from plants, etc.; outdoor allergens include pollen and fungi, etc. ② Ingestion of allergens: Common ones include milk, eggs, meat, fish, shrimp, other seafood and certain medicines. ③ Direct contact with allergens: such as cosmetics, soap, paint and certain topical medications.

2. Genetic factors Allergic diseases are a chronic development process and are related to genetics. From a clinical perspective, patients with allergic rhinitis often have a clear family history. Family and twin survey data from the 1970s have confirmed this conclusion. In addition, this genetic phenomenon is more obvious in monozygotic twins than in dizygotic twins, and children with certain genes may be particularly sensitive.

3. Environmental factors ① Air pollution: Outdoor pollution mainly comes from motor vehicles and air pollution components, such as ozone, nitrogen oxides and SO2. The main indoor pollutants include formaldehyde, toluene, etc. ② Infectious factors - "hygiene hypothesis": that is, the increase in allergic diseases is the result of a decrease in infectious diseases. The theoretical basis is that bacterial infection or contact with bacterial products stimulates the response of T helper type 1 cells (Th1), thereby inhibiting the response of Th2 and reducing the incidence of allergic diseases and asthma. In addition, there are reports that viral infection can also produce similar effects. However, the scientific basis and exact immunological mechanisms of these assumptions have not been fully confirmed.

The above are common symptoms of allergic rhinitis, which can affect the patient's life, study and work efficiency, cause some heavy economic burdens, and even induce some bronchial asthma, sinusitis, nasal polyps and otitis media. If you want to avoid contact with changes and some drug treatment methods, you must treat it in time in daily life. Genetic factors are also very critical, and some environmental factors are also very critical to the nutrition of the nose.
