warum gluckert mein bauch — what does this mean exactly?

Stomach gurgling (borborygmi) is caused by the movement of gas and fluid through the intestines. It is usually a normal part of digestion. However, certain substances like caffeine can increase bowel activity and lead to more noticeable sounds. Caffeine stimulates the gut and, in sensitive individuals or at high doses, can cause increased gurgling or even diarrhea. A small study (PMC12631023) suggests that caffeine during exercise may increase gut cell permeability, potentially contributing to these sounds. If you notice more gurgling after caffeine or exercise, there may be a link. Generally, this is harmless. But if accompanied by pain, cramping, or diarrhea, it could indicate an intolerance or irritable bowel syndrome. Consider reducing caffeine or avoiding it before exercise. Genetic testing for ADORA2A or CYP1A2 may offer clues but is not essential.
