Ms. Zhu suddenly woke up at 3:30 a.m., feeling pressure in her chest, with severe pain and launching to her back, waist, shoulders and neck, and she couldn’t move her body. Severe angina, she suspected that she had a heart attack, but check the electrocardiogram and so on everything is normal, after the hospital gastroenterology experts identified that this is a typical gastroesophageal reflux symptoms. Clinical more gastroesophageal reflux is suspected of myocardial infarction, the symptoms are exactly the same. Because the patient mostly for the night attack, to the hospital after often suspected of myocardial infarction. Hospital gastroenterologists have a lot to say about this. “Gastroesophageal reflux disease is very good at camouflage, and some of the symptoms will have the same manifestation as other diseases, thus leading to many patients have had the experience of going to the wrong department.” “For example, it sometimes presents as coughing and wheezing.” As an example, the doctor said that these can then be easily confused with laryngitis and respiratory illnesses and mistakenly treated as coughs. Often receive respiratory, cardiology, and other seemingly and gastroenterology department “unrelated” to the transfer of patients. According to incomplete statistics, about 20% of patients, due to atypical reflux symptoms run the wrong door, resulting in failure to receive timely formal diagnosis and treatment. In fact, the diagnosis of GERD is not complicated. Usually, the patient has acidity, heartburn, these symptoms, can be judged as gastroesophageal reflux. The so-called heartburn is a burning sensation in the back of the sternum. It often occurs one hour after a meal and is more pronounced when lying down, bending over, or when abdominal pressure increases. Patients can also start by making an initial judgment against the GERD chart (below). Typically, the doctor will give the patient a score and then do a PPI test, which means that if the heartburn is relieved after about a week of taking a proton pump inhibitor, the patient will essentially be judged to have GERD. There are also some exceptions, heartburn is not obvious, but the appearance of cough and other extra-esophageal symptoms, such as clinical findings of unexplained recurrent vomiting, dysphagia, recurrent chronic respiratory infections, refractory asthma, etc., and then you need to diagnose with the help of necessary auxiliary tests. Currently more commonly used is 24-hour pH monitoring, which is the gold standard for diagnosing GERD. “A 2.1mm diameter hose is placed into the esophagus through the nostril, fixed and wearing a small computerized recorder on the body, you can leave the hospital, you can eat and sleep normally, and then go back to the hospital 24 hours later to remove the tube and recorder and analyze the data.” Lifestyle changes should be used as a basic measure of treatment. Elevating the head of the bed by 15 to 20 centimeters is a simple but effective way to reduce nocturnal reflux by using gravity to enhance acid clearance during sleep. Foods such as fat, chocolate, tea and coffee will reduce LES pressure and should be appropriately restricted. In addition, gastroesophageal reflux patients should quit smoking and drinking, avoid 3 hours before bedtime satiety, avoid a long increase in abdominal pressure in the life of the various movements and postures, including wearing tight clothing and tightening of the waistband, etc., can also reduce nighttime reflux. According to statistics, 25% of patients can improve their symptoms after changing the above habits.
