While sometimes overlooked, minimally elevated liver tests may signal early liver disease or non-hepatic conditions like thyroid dysfunction. As a result, interpreting ALT and AST thresholds, assessing metabolic risk, and reviewing lifestyle factors can help shape a focused diagnostic approach and reduce liver-related complications. Joining Dr. Peter Buch to provide insights into the evaluation of minimally elevated liver tests is Dr. Paul Kwo, who’s a Professor of Medicine and Director of Hepatology at Stanford University.

From symptom trackers to multidisciplinary app-based platforms, evidence-based digital therapeutics are expanding access to brain-gut behavioral care for patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Dr. Peter Buch sits down with Dr. Iris Wang to discuss the spectrum of available tools and explore strategies for aligning them with individual patient needs. Dr. Wang is an Associate Professor of Medicine and the Associate Program Director of the Gastroenterology Fellowship at the Mayo Clinic in Rochester, Minnesota.
