Spring is in full bloom and autumn is in full swing, which is a great time to change seasons, but some people will have frequent itchy nose, sneezing and runny nose at this time. Many people think it is a “cold”, but anti-cold treatment for several weeks can not completely relieve. In fact, this is not a cold, but allergic rhinitis trouble. In recent years, the incidence of allergic rhinitis is around 10% to 40%, and the trend is increasing year by year. In China, it is conservatively estimated that there are 40 million patients, with children and adolescents being the most common. To make matters worse, rhinitis and asthma often coexist or occur sequentially. Therefore, to live a long and healthy life, it is necessary to prevent and treat allergic rhinitis in a timely manner. Allergic rhinitis is mostly associated with heredity. Some scholars have statistics that if one parent has allergic rhinitis, their children are twice as likely to suffer from allergic rhinitis, and if both parents have allergic rhinitis, their children will have up to 50% of the disease. Secondly, because there are many similarities in the living environment and habits of the same family, the disease often runs in families. Let’s analyze how to determine if you have allergic rhinitis? Allergic rhinitis is characterized by symptoms such as itchy nose, sneezing, runny nose and nasal congestion. Classification of allergic rhinitis is divided into two categories: seasonal and perennial, according to the pattern of onset. Classification by duration of symptoms: intermittent allergic rhinitis if symptoms last less than 4 days/week and the total duration of illness is less than 4 weeks; persistent allergic rhinitis if symptoms last more than 4 days/week and the total duration of illness is more than 4 weeks. The severity of symptoms can be classified as mild allergic rhinitis if it does not affect life, work and study, and moderate to severe allergic rhinitis if the opposite. In addition to medical history and routine nasal examination, specific allergen tests such as skin prick test, blood allergen test, nasal allergen provocation test and nasal secretion cytology test are usually required for the diagnosis of allergic rhinitis. Treatment of allergic rhinitis is based on comprehensive treatment, including allergen avoidance, drug therapy, immunotherapy, and surgery. Among them, avoiding exposure to allergens is the most important. Corticosteroids and antihistamines are currently the first-line drugs for the treatment of allergic rhinitis. Immunotherapy (also known as desensitization) is also considered in some severe cases, i.e., specific treatment using standardized vaccines; the aim is to control the symptoms of allergic rhinitis by directly affecting the patient’s immune system. Surgery may be considered for individual anatomical variants (e.g., deviated septum, enlarged turbinates, etc.) as well as for those with combined chronic sinusitis and nasal polyps, as appropriate. How to avoid allergens 1, dust mite allergy prevention: control the relative humidity in the room to less than 50%, use special fiber fabrics to make materials with a density of about 20 microns to pack mattresses and pillows, it can stop all dust mites through, wash and dry bedding frequently, it is recommended to remove carpets, replace curtains with blinds, replace decorative fabrics with resin or leather, replace cloth furniture with wood or leather furniture ; to vacuum frequently, often replace and clean the nano bags in the vacuum cleaner to remove the hiding place of dust mites. 2. Pollen allergy prevention: During the pollen season, live indoors and try to reduce the number of trips, even if you want to go out, you should also take protective measures. If you have the conditions, you can temporarily move to areas without allergic pollen or coastal areas. 3. Minimize the consumption of allergy-prone foods: common ones are fish, crustacean seafood (such as shrimp and crab), drupes and peanuts. Some fruits and vegetables can also trigger allergies, such as bananas, avocados, kiwi, chestnuts, papayas, pineapples, peaches, figs, cherries, celery, tomatoes, carrots. How can I prevent allergic rhinitis? You can eat more anti-allergy foods. Honey contains certain pollen grains, and those who drink it regularly will develop some resistance to pollen allergies. Honey also contains substances that improve the state of the body’s environment and regulate the body’s immunity. Drinking yogurt every day can alleviate pollen allergies to some extent. Allergic rhinitis patients can also increase the intake of foods rich in vitamin C such as cabbage, cauliflower, oranges, hawthorn, dates and lemons, or take vitamin C supplements. Allergic patients can also eat more foods such as dates, carrots, enoki mushrooms, onions and garlic, all of which contain large amounts of anti-inflammatory and anti-allergic substances that can effectively prevent pollen allergies. Improving body composition. Allergic constitution is a kind of atopic constitution, which is the primary factor for the occurrence of many allergic diseases. The influence of diet and nutrition on the constitution is obvious and certain. Changes in the nutritional composition of the diet of a person with a normal constitution over a long period of time can cause changes in the constitution. Oral allergy-regulating preparations can improve and correct the constitution. For the sake of your health and the health of the next generation, please do a good job of environmental control, reasonable diet, work and rest to prevent the occurrence of allergic rhinitis.
