Many elderly people who are obese do not sleep well at night. Heartburn, acidity, hiccups and chest and back pain sweep in the middle of the night, forcing them to sit helplessly in bed and rest, unable to fall down. They even wonder if they are suffering from myocardial infarction. According to a national case-control study presented at this year’s Digestive Disease Anniversary in the United States, it was suggested that GERD was independently associated with a 57% increased risk of a first heart attack within five years thereafter. And without corrected analysis, the risk of acute heart attack within 5 years in patients with GERD reached even six times that of those without reflux. The two experts analyzed the results of this study, which may be due to the fact that GERD patients themselves often have risk factors that overlap with heart attacks, such as obesity, or smoking. Also, some studies have suggested that GERD may cause a systemic inflammatory response, which may be associated with many diseases, such as heart attacks, or tumors. If the stomach contents only reflux into the esophagus, people will only experience relatively mild symptoms such as heartburn and acidity, but if it is a high level of reflux, such as the stomach contents reflux into the pharynx, or even being inhaled into the trachea, bronchi, or lungs, it can lead to severe coughing, coughing, asthma, breathing difficulties, and choking. Gastroesophageal reflux left unattended is prone to numerous serious consequences, so attention should be paid to changing body position and daily care when the above symptoms occur. First of all, the most effective position in the awake state is upright and sitting position, and when sleeping, keep the right side lying and raise the head of the bed 20-30cm to promote gastric emptying and reduce the frequency of reflux and reflux aspiration. Reflux is easily caused after meals, so it is not advisable to eat before going to bed, and it is not advisable to lie in bed immediately after meals during the day. Second, pay attention to reduce the general factors affecting the increase of abdominal pressure, such as obesity, constipation, tightly tied belt, etc.. Foods that lower the lower esophageal sphincter pressure, such as fat, chocolate, coffee, strong tea, etc., should be avoided. Smoking and alcohol should be abstained from. Finally, avoid applying drugs that lower the lower esophageal sphincter pressure and drugs that affect delayed gastric emptying. Some elderly patients are prone to gastroesophageal reflux due to lower esophageal sphincter function, and if they have cardiovascular disease at the same time, taking nitroglycerin preparation or calcium channel blocker can aggravate reflux symptoms and should be avoided. Some bronchial asthma patients with combined GERD can aggravate or induce asthma symptoms, so avoid the use of theophylline and β2 agonists as much as possible and add anti-reflux treatment. Although gastroesophageal reflux can be treated medically, it is difficult to eradicate the root cause. To reduce the attacks of GERD, daily life regimen is important!
