Can intense exercise lead to GI symptoms such as diarrhea or heartburn?
This article will help you understand how exercise and associated factors can influence the GI tract.
Intense or prolonged exercise—especially endurance sports like running—can commonly lead to gastrointestinal (GI) symptoms such as diarrhea, cramping, heartburn, bloating, and even intestinal bleeding. These issues often result from a combination of physical stress on the GI tract, reduced blood flow to the intestines during strenuous activity, and dietary triggers like high-fiber foods or sugary sports drinks. While mild symptoms can often be managed with adjustments to hydration, diet, or exercise type (e.g., switching from running to swimming), persistent or severe issues should be evaluated by a healthcare provider to rule out underlying conditions and develop an appropriate management plan.
