What Is Leaky Gut And How Can You Prevent It?

Alicia Romano, MS, RD, LDN, CNSC, specialized ambulatory and nutrition support dietitian at the Frances Stern Nutrition Center, answers:

“The intestinal lining is a tight barrier, controlling what gets absorbed into the bloodstream. Leaky gut, defined as increased intestinal permeability, refers to a loosening of this barrier that allows for the absorption of material that does not normally enter the body. This may lead to inflammation and changes to the gut microbiome, potentially causing adverse effects related to the gastrointestinal (GI) tract—and perhaps even beyond.

Increased intestinal permeability plays a role in GI conditions such as celiac disease, Crohn’s disease and irritable bowel syndrome (IBS). Researchers are exploring a possible role in autoimmune conditions such as lupus, multiple sclerosis, fibromyalgia, and rheumatoid arthritis, but much more research is needed.

“Although there is no proven cause-and-effect relationship, heavy alcohol use, stress, and a typical American diet (low in fiber and high in refined sugars) have been associated with drivers of gastrointestinal inflammation linked to leaky gut syndrome. Shifting to a dietary pattern with plenty of fiber-rich plant foods is one way of eating that not only improves gastrointestinal health but is also good for general health.”


You can, but the approach is similar to diagnosing a broken car, says Dr. Fasano. “You don’t know the exact problem until the mechanic lifts the hood, looks around, and tries different things — there is not a simple, direct approach to fixing the problem,” he says. “It’s the same with leaky gut. We have to try different strategies to see what helps.”

Your first step is to share your symptoms with your doctor. If leaky gut is a possibility, he or she can try several strategies to help relieve symptoms and reduce inflammation. The most common is to review your diet and eliminate known dietary causes of inflammation, such as excessive consumption of alcohol and processed foods, and to explore whether you have any food sensitivities — for instance, to gluten or dairy. “In theory, reducing inflammation from your diet like this also may rebuild the gut lining and stop further leakage,” says Dr. Fasano.

The best way to protect yourself from leaky gut is to invest more in your overall digestive health, he adds. This means being more attentive about following a gut-healthy diet that limits processed foods and high-fat and high-sugar foods, and includes enough fiber. Sticking to a regular exercise program also can strengthen your digestive system. For example, studies have suggested that taking a 15-to 20-minute walk after a meal can aid in digestion. “Your gastrointestinal system is complex, but caring for it doesn’t have to be,” says Dr. Fasano.
