How Your Brainstem Can Learn a Wrong Pattern After Surgery

What this episode covers

After gallbladder surgery, some patients develop severe bloating that has nothing to do with gas. The condition, abdominophrenic dyssynergia (APD), is a mechanical coordination breakdown where the diaphragm and abdominal wall contract against each other instead of relaxing in sequence. This episode explores how surgery can disrupt visceral-somatic signaling through the vagus nerve to the brainstem, locking in a maladaptive reflex that conscious effort can't override. We cover the diagnostic challenges, why standard treatments fail, and why biofeedback — not pills — is the most promising path to retraining the body's subconscious coordination.
