Abstract
Postpartum bowel symptoms are often attributed to tissue injury, pelvic-floor trauma, or abdominal diastasis. Structural measures do not capture task-specific diaphragm–abdominal-wall–pelvic-floor function. This critical narrative review proposes an abdominopelvic-to-gut model for a susceptible postpartum subgroup. PubMed/MEDLINE, Scopus, and Web of Science were searched till 8 August 2026; 40 reports were included (12 Core; 28 Supporting). All 34 primary reports among the 40 retained received preliminary design-specific appraisal. Route A connects pressure–outlet dysfunction with inefficient evacuation, retention, and possible transit delay. Its relatively closer support comes from non-postpartum physiological studies and selected postpartum anorectal and symptom outcomes, without demonstrating stabilization-mediated transit change after childbirth. Route B links respiratory mechanics to bowel displacement, accommodation, and possible pressure-dependent fluid transport; its postpartum bowel effects remain hypothetical. Transit and stool residence may connect mechanics with microbial metabolism, while diet and lactation can modify or independently generate intestinal changes. The contribution is an integrated, falsifiable framework, not validation of the full causal chain. Functional, bowel, and nutritional measurements must be synchronized to test its links.
