The biggest problem is usually leaky gut is being caused by a health problem. I was hypothyroid and it was terrible because the doctors kept saying I was not because I was in the middle of their scale. However, by a GI test kit I found out I had parasites, candida, leaky gut, Small Intestinal Bacterial Overgrowth (SIBO) and I lost 54 pounds before it was fixed in two years. Therefore, I have little faith in the vast majority of Traditional Doctors. It came back in October. Seems like I have them all again and I am awaiting the test results. I had a heart issue and ended up needing a pacemaker which may have been the driver of this. My doctor treats candida 1st but if you have parasites that are untreated then candida will not go away. You need to find a doctor willing to do a good GI Test kit to find what is wrong. You may be able to find one at acam.org if you are in the USA. It all can be very complicated. Best wishes.
