"Glass stomach" is typically a metaphor referring to a stomach that is prone to irritation and damage, as fragile as glass. This condition often occurs because the gastric mucosa is relatively weak and susceptible to stimulation from stomach acid, food, medications, etc., leading to symptoms such as stomach discomfort, pain, and indigestion.

The causes of a glass stomach may be related to gastric conditions such as inflammation, infection, or ulcers, as well as factors like irregular eating habits, consumption of spicy or irritating foods, smoking, and alcohol consumption.

If your stomach is sensitive, it is recommended to pay attention to your diet, avoid spicy, greasy, and irritating foods, avoid overeating, and refrain from bad habits such as smoking and drinking alcohol. If symptoms are severe or persist without relief, it is advisable to seek medical attention promptly, undergo examinations such as gastroscopy to identify the cause, and take appropriate treatment measures.
