This sort of makes me laugh. While I totally agree that we are always too eager to find the diagnosis to fit all ailments, I had an experience many years ago that has me sold on the leaky gut theory. My son was 7 years old (more than 20 years ago) and was on meds for recurring strep, asthma and allergies. As his symptoms increased, more meds were added. Albuterol, symbacort, claritin, motrin, muccinex…..He kept getting worse. Fevers increasing, more wheezing, more hives, more swollen glands. Regular doc recommended surgery for adenoids and tonsils. Naturopath diagnoses leaky gut and changed his diet and meds. In six weeks, all symptoms were GONE. He has not had a single strep or sinus infection since then. Just sayin’
