Indigestion is often misunderstood. It is not only a chemical issue. It is not only about acid. It is not only about food. Digestion is mechanical. The stomach needs space. It needs rhythm. It needs pressure balance. When the front wall tightens, when the rib cage collapses, when the diaphragm stops moving fully, when the spine loses extension, digestive movement slows. This book approaches indigestion from structure, posture, muscle tension, and autonomic regulation. Inside you will discover: • How muscular compression alters digestive mechanics • The role of the diaphragm in pressure control • How thoracic alignment affects gastric mobility • The relationship between stress and vagal tone • A practical 10-minute daily reset routine • Targeted self-release methods for key muscle groups • A structured 4-week integration plan This is not symptom management. This is structural correction. Restore space. Restore movement. Restore rhythm. When structure improves, digestion follows.
