Two reasons to know allergic cough.
The respiratory tract has the functions of respiratory organs, sensory organs and immune organs. When we inhale allergens, it may trigger the body's immune response and lead to inflammation of respiratory mucosa. This situation is called allergic cough. Allergic cough has two main reasons:
1, caused by external factors:
Climate inducement, cold air, air humidity and air pressure changes can all induce allergic cough's attack.
In areas with large temperature difference, high humidity or low air pressure, the incidence rate in allergic cough has obviously increased. When allergic cough patients from these areas go to areas with dry climate and high air pressure, the situation in allergic cough can often be alleviated. The mechanism of allergic cough induced by cold air is that cold air can lead to the loss of airway heat, make mast cells release mediators, directly or indirectly induce airway inflammation, and cause allergic cough's attack. Too high or too low temperature is a disadvantage for allergic cough.
Hyperactivity and hyperventilation:
Examples of exercise-induced allergic cough are very common in clinic. For most patients with allergic cough, exercise is only the inducing factor, while for patients with exercise-induced allergic cough, exercise may be the pathogenic factor. In fact, all patients with allergic cough's disease and some patients with allergic rhinitis can have wheezing symptoms after a certain amount of exercise. Its mechanism is related to hyperventilation caused by excessive exercise, which leads to excessive heat loss in the airway and cold airway environment, thus inducing mast cells to release inflammatory mediators and leading to airway inflammation. Hyperventilation caused by laughter and crying in children with allergic cough often induces wheezing symptoms.
Exposure to allergen-like stimuli can induce:
Such as pollen, indoor dust, dust mites, mold, animal fur, cockroaches, feathers, food and so on. Because these may become allergens, and some toxic substances in the room are also one of the causes of allergic cough. For example, the newly renovated house is seriously polluted, and some chemical gases (including the smell of decorative materials such as paint, benzene and formaldehyde) will cause allergic cough; There are also some chemical pesticides containing DDV in life that can also be induced; Even if such people are exposed to all kinds of smog, such as smoking, lampblack or all kinds of smog, allergic cough may appear.
2. Gene composition
Allergic cough often occurs in people with allergic constitution. Patients in allergic cough are allergic, but the opposite is not true (people with allergic constitution may not get allergic cough); Allergic cough is not a patent for people with poor physique and allergic physique. Some able-bodied people will also appear in allergic cough.
Allergic constitution includes individual hereditary allergic constitution, immune status, endocrine and health status, which is an important factor in allergic cough. In addition to past allergic history or family history such as asthma, there are other allergic diseases. In addition, the number of eosinophils in peripheral blood and the increase of total IgE and specific IgE antibodies in serum suggest the existence of allergic constitution. Therefore, if the allergic constitution is not improved, it will be difficult for allergic cough to be cured.
Pay attention to four points of daily prevention and control in allergic cough.
1, avoid allergens
Patients can know what they are allergic to through allergen testing, and then avoid allergens.
In fact, inhalation is the most common allergen among patients in allergic cough. Common allergens are: house dust mite, dermatophagoides farinae, mold, cockroach, animal dander, pollen, mulberry, willow, phoenix tree, cypress, pine and fir.
Allergic cough patients should not only keep indoor air humidity, or use air filters to prevent respiratory discomfort, but also improve the indoor environment, stop raising cats and dogs, replace carpets and feather bedding, reduce indoor dust, keep indoor ventilation, and often open windows for ventilation.
For example, in the cold winter, you should try to avoid catching a cold.
Allergic cough is repeatedly refractory in winter? Doctor: Gradually eliminate cough in four ways.
2. Immune antiallergic treatment to improve allergic constitution.
Allergic cough's treatment needs to start from the internal causes and adjust the allergic constitution. Relevant medical research shows that taking anti-allergic probiotics can reduce allergic constitution and promote human tolerance to allergens by modifying immune response.
So, how can Xinmin Kang probiotics recuperate allergic constitution and restore immune question and answer? Because its main components are six kinds of active lactic acid bacteria: Lactobacillus salivarius, Lactobacillus rhamnosus, Lactobacillus acidophilus, Streptococcus thermophilus, Lactobacillus lactobacillus paracasei and Lactobacillus Roy. The raw materials of these strains are the most researched anti-allergic probiotics in the world. Xinmin Kang probiotics contact with a special cell in the intestine, colonize and enter the blood. By activating a series of cell reactions, they produce a series of physiological reactions of immune T cells, which can eventually reduce the antibody-immunoglobulin IgE in human blood, induce correct immune responses and relieve allergic constitution. Completely solve allergic cough's repeated cough, even bronchial contraction, asthma, rhinitis, conjunctivitis, skin diseases caused by asthma and other allergic symptoms. At the same time, it can shorten the period of taking antiallergic drugs and help children with cough and asthma who have been controlled by antiallergic drugs for a long time to reduce or stop taking drugs.
3. Reconstruct the concept of allergy
Don't use antitussive and anti-inflammatory drugs as soon as you cough. Because cough is the only symptom in allergic cough's disease, its clinical features are not specific and its misdiagnosis rate is high. Many people treat bronchitis, chronic bronchitis, chronic pharyngitis or respiratory infection as diseases. Generally, a large number of antibiotics and cough drops are used to relieve inflammation and cough. Because there is no treatment for the cause, the symptoms of patients are difficult to be alleviated, and even the more they are treated, the more they cough.
Don't stop using antiallergic drugs for children in remission, which will lead to the allergic inflammation of respiratory tract not being completely and effectively controlled, thus leading to the recurrence of allergic asthma or allergic cough.
Step 4 pay attention to your diet
Diet should be light, eat more fresh fruits and vegetables, such as radish, loofah, pear, apple, orange, loquat, grape and walnut. Dietary taboos, do not eat fishy and greasy seafood, such as shrimp (especially sea shrimp), crab (swimming crab), mandarin fish, yellow croaker, crucian carp, fat, lard and so on. Eat less internal organs of animals. Be careful to eat mustard, celery, fermented grains and other hair products. Usually, the diet is sweet, salty, cold and hot. Spicy products irritate the pharynx, causing severe cough, choking cough and cough variant asthma. Use with caution.
