Gastroesophageal reflux disease is a symptom and complication caused by the regurgitation of stomach contents into the esophagus, mouth (including the larynx) or lungs. It includes intraesophageal symptoms: such as acid reflux, heartburn, and retrosternal pain, and extraesophageal symptoms: such as chronic cough, asthma, and chronic pharyngitis. The prevalence of GERD in the general population is 5-10%, while the prevalence in the asthmatic population is as high as 34% – 89%. Many GERD patients have “asthma” like symptoms, which can cause laryngotracheal spasms (closed vocal cords) and airway obstruction, resulting in death by suffocation within a short period of time. In contrast, ordinary asthma usually causes bronchospasm and does not cause airway blockage, so as long as the patient takes medication and seeks medical attention in a timely manner, the patient’s life is generally not in danger. At that time, Teresa Teng was on vacation in Thailand, her asthma symptoms should not be serious, otherwise the doctor would not have agreed to her travel, and with Teresa Teng’s wealth and status, she should have been treated and controlled under very good medical conditions, so the chances of her dying from an acute asthma attack were relatively small. Experts speculate that he may have died of laryngotracheal spasm due to excessive alcohol consumption, which induced or aggravated GERD. In clinical practice, we often encounter patients with GERD who “go to the wrong door” and delay the diagnosis and treatment. When the following symptoms appear, you should be highly alert to GERD. 1. Acid reflux, heartburn, chest pain or regurgitation, bloating, belching, constipation, and other symptoms. 2.Cough is induced or heavy after a full meal or eating an irritating diet. 3.Choking symptoms when eating or drinking. 4.Cough is easily triggered or aggravated in the lying position and can be reduced, relieved or disappeared after sitting up. 5. Cough can be reduced or relieved after regurgitation, belching and laxative. Therefore, when coughing and wheezing occur, it is carefully screened whether it is asthma or gastroesophageal reflux disease.
