Gastroesophageal flow disease is the reflux of stomach and duodenal contents from the bottom up into the esophagus, and even the pharynx and trachea, causing a series of symptoms and complications, Renxin It is a very common digestive tract disease. With the change of the public lifestyle, the acceleration of the pace of life, and the increase of obese people, its incidence is increasing, and it is reported that the incidence in the Chinese population is close to 6%. Under normal circumstances, after eating, food enters the stomach cavity through the mouth and esophagus, then along with the peristaltic movement of the gastrointestinal sphincter, the food is pushed to the distal end of the digestive tract, during which nutrients are gradually absorbed. When gastroesophageal reflux occurs, some of the gastrointestinal contents as well as stomach acid, protease, pancreatic enzymes, bile salts and other substances contained in digestive juices will enter the esophagus and repeatedly stimulate the esophagus, resulting in heartburn, acid reflux, vomiting, pain and discomfort behind the sternum or in the upper abdomen, which sometimes radiates to the back, left shoulder or even the root of the neck, similar to “angina pectoris “These symptoms are actually caused by esophagitis. In addition to this, patients can also experience symptoms other than esophagitis, which can cause pharyngitis, laryngitis, chronic hoarseness, as well as chronic cough, interstitial pneumonia, asthma attacks, and even nocturnal asphyxia due to reflux entering the throat and trachea. What causes gastroesophageal reflux to occur? Under normal circumstances, there exists a natural barrier in the esophagus to prevent gastric contents from refluxing into the esophagus, including the tonic contraction of the lower esophageal sphincter, contraction of the esophageal wall, and contraction of the diaphragm, etc. When this natural anti-reflux barrier is damaged, gastrointestinal contents will reverse into the esophagus and damage the esophageal mucosa, and then the above symptoms will occur. Some bad habits in our daily life: alcohol consumption, smoking, obesity, etc., and the presence of certain diseases (e.g. esophageal hiatal hernia) can affect the natural barrier of the esophagus and lead to the occurrence of gastroesophageal reflux. Because GERD is a chronic condition, it can be overlooked, especially when symptoms are mild. However, it is worth noting that without effective treatment for a long time, it can affect a person’s quality of life and reduce work efficiency. Due to repeated episodes of esophagitis, esophageal ulcers can occur, leading to hemorrhage and life-threatening, and severe esophagitis can lead to esophageal stricture and even induce esophageal cancer. Therefore, it is important to get our sufficient attention. GERD is a chronic recurrent disease, and maintaining a good lifestyle plays an important role in the recovery of the disease. In life, we should pay attention to the following aspects: (1) to develop good and regular eating habits, mainly high protein, high fiber and low fat, avoid eating chocolate, too acidic and too sweet food, etc., and drink as little as possible some drinks that stimulate gastric acid secretion, such as coffee, strong tea, cola, citrus drinks, tomato juice, etc.; (2) to reduce the amount of food at each meal, avoid eating 2-3 hours before going to bed, to move properly after meals, not also immediately lie down, sleep with the head of the bed elevated, or pad the upper body. (3) Obese patients should, increase physical exercise, control weight. (4) Quit smoking and alcohol. For the treatment, including medical treatment and surgery. Since the efficacy of different drugs for GERD varies. Therefore the course of treatment also varies. For treatment of GERD with proton pump inhibitors, the course of treatment is usually 4-8 weeks, which can be extended to more than 4 weeks if the esophagitis does not heal after 4 weeks of taking them or if the symptoms still persist. For long-term medication that is ineffective, or long-term medication that cannot be stopped, recurrence once stopped, esophageal stricture, or even cancerous tendency, surgery is required.
