Hello,
Leaky gut is basically a proposed condition of an altered or damaged bowel lining. It is not a recognized diagnosis and there are no diagnostic tests which can prove this condition. It is often described in association with gluten intolerance
because a gluten free diet has been helpful in improving the symptoms. But this is not a confirmed medical condition.
Treatment includes gluten-free diets, casein-free diets, antifungal diets, low-sugar diets, as well as supplements that include nystatin, B12, and probiotics.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
