Stomach bloating and burping after each meal are related to improper diet, peptic ulcers, stomach cancer and other diseases. You should chew and swallow slowly in your daily diet, so that food and saliva can be neutralized to reduce the burden on the digestive system. If you overeat or eat too fast, you will not only increase the burden on the digestive system, but also cause bloating because the food is too rough to digest. When the stomach is overly dilated, the diaphragm is irritated by the diaphragmatic ligament, and hiccups occur. In patients with peptic ulcer disease, stomach acid can damage the ulcer surface after food intake because the food stimulates the gastric glands to secrete gastric acid, which can cause pain in the stomach and affect the stomach’s digestion of food, resulting in a distended feeling in the stomach. Some patients with peptic ulcers may have hiccups caused by spasmodic contraction of the stomach wall and irritation of the diaphragm. Stomach cancer not only affects the digestion of food in the stomach, but also causes various symptoms due to the invasion of cancer cells into the surrounding organs. There are many symptoms caused by stomach cancer, such as stomach bloating, indigestion, acid reflux, belching and hiccups.
