What causes stomach vomiting?

Stomach vomiting generally refers to belching, which may be related to functional dyspepsia, chronic gastritis, gastric ulcer and other causes.

1. Functional dyspepsia

Functional dyspepsia is mainly caused by visceral hypersensitivity, excessive gastric acid and other factors. Reduced digestive function will prolong gastric emptying time, leading to a large accumulation of food, resulting in belching.

3. Chronic gastritis

Chronic gastritis causes chronic inflammation in the stomach, which is easy to make food intake unable to be digested and absorbed in time, causing belching.

3. Gastric ulcer

Gastric ulcer is generally related to Helicobacter pylori infection, long-term use of non-steroidal anti-inflammatory drugs and other factors. After eating, food accumulates in the stomach for a long time and may cause belching.
