An upset stomach when eating rice may be caused by physiological reasons such as overconsumption or pathological reasons such as indigestion and chronic gastritis.
1. Physiological reasons: rice is a relatively everyday food, containing a lot of starch. If you eat too much rice, stomach acid will secrete in large quantities, stimulating the gastric mucosa and causing gastric discomfort whenever you eat rice.
2. Pathological causes
(1) Indigestion: There are obstacles to the digestion and absorption of food, and food cannot be completely digested and absorbed. When you eat rice, the undigested rice will not only stay in the stomach, but will also continuously stimulate the stomach to secrete gastric acid, leading to fermentation and gas production and gastric acid stimulation of the stomach wall, resulting in an upset stomach when you eat rice.
(2) Chronic gastritis: The stomach has long recurring inflammation, and eating rice and other foods will stimulate the secretion of gastric acid, which will stimulate the inflammation to aggravate, resulting in an upset stomach when you eat rice.
The cause of gastric upset when eating rice cannot be accurately determined by itself, but also needs to be combined with the characteristics of the medical history and other test results to make an accurate judgment, and it is recommended to clarify the cause of the disease under the guidance of a doctor, and then carry out reasonable and standardized treatment or therapy.
