The reason for bloating when you eat a little bit of stomach may be having gastritis, gastric erosion, peptic ulcer, and possibly functional indigestion or imbalance of intestinal flora. First of all, eating too much, like to overeat, like to eat fried, spicy, irritating food, smoking and drinking seriously, all these reasons can lead to underlying diseases in the body, such as gastritis, gastrointestinal celiac disease, gastric ulcer, etc., so that the gastric mucosa is damaged, it appears to eat a little to produce the feeling of bloating. Secondly, functional dyspepsia occurs because of the consumption of indigestible food, which leads to a weakening of the peristaltic ability of the intestines and stomach, so the stomach becomes bloated when eating a little. Then if there are other harmful bacteria such as Helicobacter pylori in the abdomen, it will destroy the beneficial flora in the intestinal tract, resulting in an imbalance in the intestinal flora, which will also cause the adverse reaction of bloating when you eat a little.
