Functional Medicine management of leaky gut involves
a restricted dietary regimen avoiding foods that can damage the intestinal lining together with the use of nutritional supplements to help reduce the intestinal inflammation and repair the intestinal lining.
A physician without specific training in nutrition would be able to refer to a nutritionist, who can help the person meet all of their
dietary needs on a calorie
restricted regimen, which may or may not include the use of juice fasting.
