Are you suffering from constipation, bloating, gas, or diarrhea? Do you have irritable bowel, colitis, Crohn's, leaky gut, or anxiety — or some combination of these? Dr. Kellman's work begins with the barrier between your gut and the rest of your body.
The intestinal lining is designed to be selective, admitting nutrients while holding back everything else. When that barrier loosens, partially digested food particles, microbial fragments, and toxins reach the bloodstream.
The immune system responds to what it finds there. That response is why gut permeability shows up not only as digestive symptoms but as fatigue, joint pain, skin conditions, mood changes, and autoimmune activity.
Dr. Kellman has written extensively on leaky gut, including Leaky Gut Syndrome & Digestive Function: Using the Power of the Microbiome, the first book in his Microbiome Health Series.
Treatment restores the microbiome that maintains the barrier — removing what is driving the damage, rebuilding the lining, and re-establishing the microbial balance that keeps it intact.
Increased intestinal permeability is well documented in the research literature and measurable. Dr. Kellman has treated it as a central clinical target for decades and has published a book on it.
Yes. Because a large share of immune tissue surrounds the intestine, a compromised barrier produces immune and inflammatory effects that surface as fatigue, joint pain, skin conditions, mood symptoms, and autoimmune activity.
