Stomach distension may cause heart discomfort, mainly because of the similar anatomical location of the two. In addition, acid reflux and a history of heart disease may cause this condition. It is recommended to regulate the diet and seek timely medical attention to give reasonable treatment. Common causes and treatments are as follows: 1. Anatomical location: Behind the heart is the esophagus and below the left is the stomach. When the stomach is distended, the stomach will top the heart through the diaphragm, causing uncomfortable symptoms in the heart. At this time, patients should actively treat abdominal distension and can take digestive enzymes and probiotic tablets under the guidance of a doctor. Heart discomfort can be relieved after the symptoms of abdominal distension disappear; 2. Acid reflux: Acid reflux may occur when patients are distended, which can lead to heartburn, followed by possible vague pain in the precordial region, palpitations, chest tightness, shortness of breath, and other symptoms. The symptoms of bloating can be relieved by taking acid suppressants and gastrointestinal motility drugs, thus relieving heart discomfort. 3. History of heart disease: If patients themselves have heart disease, such as coronary heart disease, myocardial ischemic attack, primary cardiomyopathy, heart valve disease, etc., stomach bloating may trigger heart-related diseases, resulting in symptoms such as accelerated heart rate and elevated blood pressure, leading to the onset or aggravation of the original heart disease. It is recommended to use spironolactone, furosemide and nitroglycerin under the guidance of a doctor to control blood pressure and relieve heart discomfort. In addition, fasting for gastrointestinal decompression should be performed to relieve the symptoms of gastric distension. Patients with gastric distension should actively adjust their dietary structure, or they can temporarily stop food intake and drink less porridge to promote gastric emptying and relieve distension. After 30 minutes of eating, you can do the action of bending your knees and holding your legs and repeat it several times, or perform other sports in moderation, which can accelerate intestinal peristalsis and effectively relieve gastrointestinal distention.
