What is the reason for the old anti-gas?

The causes of old upward gas include improper diet, indigestion, chronic gastritis, etc. The specific analysis is as follows:

1. Improper diet

Because patients eat a lot of gas-rich foods, such as taro, pear, pumpkin, potato, etc., it is easy to cause a lot of gas in the stomach, causing old upward gas.

2. Indigestion

Because indigestion will prolong the time that food stays in the stomach, as food decomposes, more gas will be produced, resulting in old upward gas.

3. Chronic gastritis

Because chronic gastritis will affect the gastric emptying speed, food cannot be digested in time, and it is easy to ferment in the stomach, generating gas, and causing old upward gas.
