Why does taking Acarbose (Bay Tangping) increase the frequency of bowel movements?

Bay糖平, its chemical name is acarbose, is a commonly used medication for lowering postprandial blood glucose. The main mechanism of action of this medication is to inhibit the absorption of carbohydrates in the small intestine, thereby exerting a blood glucose-lowering effect. However, during this process, the drug may also affect normal gastrointestinal function and cause gastrointestinal discomfort as side effects, including bloating, diarrhea, or increased frequency of bowel movements. This is because undigested carbohydrates ferment in the intestines, producing gas that stimulates intestinal peristalsis, leading to increased bowel movements.

Specifically, Bay糖平 may increase gastrointestinal motility, causing faster intestinal peristalsis. This mechanism of action can lead to an increased frequency of bowel movements in some patients after taking Bay糖平. Additionally, it may cause increased intestinal gas, more frequent flatulence, and loose stools or other gastrointestinal symptoms. Usually, these side effects are more pronounced at the beginning of treatment, but over time, most patients' bodies gradually adapt, and the symptoms may lessen or disappear. It is recommended that patients follow medical guidance for proper medication use and pay attention to their body's responses. If significant discomfort occurs, patients should seek medical attention promptly.
