The general public knows that asthma has a great impact on our quality of life and can be fatal in serious cases. Patients who have asthma symptoms are very nervous and will seek medical attention in time, but they often think that nasal diseases are minor problems that are not relevant, not knowing that allergic rhinitis, sinusitis, nasal polyps and other nasal diseases can trigger and aggravate asthma if they are not treated effectively. Mr. Zhang’s nose has been a problem for seven or eight years, often sneezing, runny nose, nasal itch, nasal blockage, headache, originally thought that the nose is not a big problem, it has not been formal treatment, just go to the drugstore to buy some drugs “to deal with deal with”, three years ago Mr. Zhang had breathing difficulties, wheezing and other symptoms, the hospital diagnosed asthma, since the beginning of long-term The quality of life has been seriously affected by the use of medication to control it, and once he caught a cold, he was always worried about asthma attacks. The last two years the situation is worse, nose symptoms are getting heavier, and there is a serious nasal congestion, it is impossible to sleep at night, rely on the drugstore to buy nasal drops static treatment, the original two or three times a day with the drug, the nose can still pass some air, but then use more and more times, developed into the middle of the night have to get up several times with the drug, it is simply painful, when he visited the doctor, was diagnosed with nasal polyps, allergic rhinitis, asthma, the doctor recommended that he The doctor suggested him to remove nasal polyps surgically and treat allergic rhinitis regularly, and told him that if his nose was cured, the treatment of asthma would also be greatly beneficial. Mr. Zhang listened to the doctor’s advice and underwent surgery to treat nasal polyps and started standardized treatment of allergic rhinitis. In addition to medication, he also underwent desensitization treatment for mites at the same time. After a period of treatment, the situation has changed dramatically, his nose is better, not only can he breathe freely, he can also smell the fragrance of flowers, and his asthma has also improved greatly, the use of drugs has also reduced a lot, even when the cold has not triggered asthma attacks, Mr. Zhang’s life has become nourishing and tasty. Allergic rhinitis, sinusitis, nasal polyps and other nasal diseases and asthma are very common respiratory diseases in clinical practice. Although they involve the upper and lower respiratory tracts respectively, they share similar pathogenesis: they are all inflammatory diseases of the respiratory tract, caused by dysregulation of immune mechanisms and airway hyperreactivity, with similar inflammatory mediators (histamine, leukotrienes, etc.) and inflammatory cells (mast cells, eosinophils, megakaryocytes and T cells) are involved and there is a definite genetic predisposition. Eighty to 90% of asthmatic patients have allergic rhinitis and sinusitis, nasal polyps and other nasal diseases, while the proportion of asthma among patients with allergic rhinitis can also be as high as 50%. Without standardized treatment, about 1/3 of patients develop asthma after several years, and nasal disease attacks in asthmatic patients can induce aggravation of asthma attacks. For patients with allergic rhinitis if effective treatment measures are taken early in the onset, asthma is more likely to be avoided. Therefore, Grossman proposed the idea of “one airway, one disease” between nasal disease and asthma as early as 1997, and the concept of co-management of the two diseases has been accepted by more and more ENT and respiratory physicians. Therefore, patients with allergic rhinitis, sinusitis and nasal polyps must pay attention to the treatment of nasal diseases, and never neglect the health of the nose, which can be effectively controlled to prevent and treat asthma.
