A review of published studies has found that excessive exercise can compromise your gut integrity and function.
According to Dr. Ricardo Costa, lead author of the Alimentary Pharmacology & Therapeutics review, exercise stress of two or more hours at 60 percent of your maximum intensity level appeared to be the threshold where gut issues can develop, irrespective of your fitness level.
Increasing the intensity and duration of exercise leads to a risk in gut damage and gut function. Specifically, the cells of the intestine are injured and the gut becomes more leaky, allowing pathogenic endotoxins normally present and isolated to the intestine to pass into the bloodstream. “This scenario of exercise-induced gastrointestinal syndrome can lead to acute or chronic health complications,” says Costa. Gut problems may also be exacerbated by exercising in hot temperatures.
“While there is evidence for health benefits of moderate exercise in patients with inflammatory bowel disease or functional gastrointestinal disorders, the safety of more strenuous exercise has not been established.”
In fact, too much exercising for too long triggered what is commonly known as “leaky gut syndrome”. Poor gut health has been linked to not only the risk of inflammation but also to conditions ranging from diabetes and high blood pressure to obesity and colon cancer.
