Cough is a common clinical condition with complex etiology. In ENT clinics, we often see many patients who come to the clinic with itchy throat and cough, complaining of paroxysmal throat itch and choking cough. Many people do not know enough about this, so that they miss the treatment and mistreat it. In fact, this is a cough due to a lesion in the throat, which is different from the cough caused by bronchitis or lung infection and is also called laryngogenic cough. In recent years, the incidence of laryngeal cough has been on the rise due to the greenhouse effect, dry air, environmental pollution, stimulation by dust and odorous gases in the air, and bacterial and viral infections. Laryngogenic cough, also known as allergic pharyngitis and allergic pharyngitis, is an allergic disease that commonly occurs in the throat. Clinically, it has been shown that most patients with allergic pharyngitis develop due to allergens reaching the throat from the nasal and oral cavities and irritation of the mucous membrane of the throat. The characteristics of allergic pharyngitis are: 1. cough with pharyngeal itching, foreign body sensation in the throat, dryness, vague pain, etc., little or no sputum, cough mostly occurs before bedtime or in the morning, mostly paroxysmal, can be triggered by irritating odors 2. some patients have a history of cold or irritant exposure before the onset of the disease (including new house renovation, etc.) 3. patients have had other allergic diseases, such as allergic rhinitis, etc., and some patients have a history of laser, microwave, cryotherapy, etc. in the throat. Some patients have a history of laser, microwave, freezing and other treatments. 4, examination is seen in the pharynx congestion, posterior pharyngeal wall lymphatic follicle hyperplasia, the onset of the initial chest X-ray is often no obvious abnormalities. Therefore, when you appear similar to the above symptoms, do not blindly use a large number of anti-inflammatory cough syrup and tablets, because too sweet products, not only to help wet phlegm, but also to block the body of the evils out of the drawbacks; such as simply taking too many antibiotics, not only the effectiveness of allergic diseases, may lead to the normal flora of the throat dysbiosis, but also cause bacterial resistance to strengthen, low immune function, reduced resistance, resulting in The disease is recurrent and difficult to be cured. Prevention and treatment of allergic pharyngitis Since allergic pharyngitis is a metabolic disease, it should be treated with active anti-allergy and symptomatic treatment. We treat this disease on the basis of dialectical treatment, in addition to the use of self-designed Chinese medicine, anti-allergic treatment, but also localized with drug nebulization inhalation, which can directly dilute and remove the secretions and allergens in the throat, faster alleviate the allergic reaction, reduce the hyperreactivity of the vagus nerve, internal and external combined treatment, the efficacy is remarkable; if accompanied by allergic rhinitis, rhinitis, sinusitis and other diseases, there is a backflow of secretions to stimulate the pharynx. The related diseases should be treated actively. Many patients with allergic pharyngitis think they have a cold or flu at the beginning of the disease and do not pay enough attention to it, thus delaying treatment; some patients do not treat allergy symptoms in a timely manner, but are often treated according to bronchitis, pneumonia, etc., resulting in prolonged illness. Repeated attacks can also easily lead to the combination of other infections, which greatly increases the difficulty of treatment. In addition, there are many external factors that can directly aggravate allergic pharyngitis in life. For example, sudden cold weather, dry air, exposure to irritating odors, consumption of sweet drinks, large quantities of seafood, addiction to smoking and drinking, prolonged depression, excessive tension and fatigue in life and work, etc. can directly affect the degree of pharyngitis attacks. Therefore, for patients with allergic pharyngitis, enhancing the body’s cellular immunity and improving allergies is the core aspect of preventing and treating allergic pharyngitis. Usually try to stay away from allergens that may trigger the disease, avoid contact with irritating odors, avoid eating spicy, sweet and sour, mutton, fish and shrimp seafood products, adhere to the morning gargle with light salt water, etc., to prevent colds and reduce the recurrence of the disease.
