There is no such thing as the best exercise for a bad stomach due to the differences in personal constitution and condition. Patients with a bad stomach can properly carry out aerobic exercise, such as walking after meals, brisk walking, jogging, cycling, mountain climbing and so on. There are many reasons for bad stomach, such as chronic gastritis, gastric ulcer, etc., which can lead to the slowing down of gastrointestinal peristalsis, affecting the patient’s digestion and absorption function. Patients with a bad stomach can usually be adjusted through appropriate exercise, such as walking, brisk walking, jogging, cycling, mountain climbing, Tai Chi, jumping rope and other aerobic exercise. Aerobic exercise can promote gastrointestinal peristalsis, improve blood circulation, and enhance the patient’s gastrointestinal function. When patients are choosing exercise, they should choose reasonably in combination with their own physical condition to avoid affecting their health because of too intense exercise. Patients with stomach problems are advised to seek timely medical treatment to identify the cause of the disease and carry out targeted treatment to avoid delaying the condition, and consult a professional physician for advice on what exercise is suitable for them.
