Abdominal Massage for Constipation: What the Trials Tested

If you are considering abdominal massage for constipation, ask who would teach you, how often you would do it and what would count as improvement. Those details let you compare a proposed routine with the treatments studied.

The placebo-controlled trial used a physical therapist

In the 2022 trial¹, 74 adults with Rome IV functional constipation received lifestyle advice plus massage or sham ultrasound. A physical therapist delivered 10-minute massage sessions three times weekly for four weeks. The comparison involved an inactive ultrasound head moved over the abdomen for 15 minutes twice weekly. Weekly treatment time matched; visit frequency differed.¹

Constipation-severity scores fell approximately 70% with massage versus 28% with sham treatment. These are reductions in average symptom scores, not percentages of participants cured. Bowel frequency and stool consistency also favored massage.¹

The study measured short-term outcomes, without bowel-transit testing or anorectal manometry. Its supervised treatment does not establish the effect of an untrained person rubbing their tummy briefly.¹

A family-delivered trial had training and reporting problems

A 2025 Iranian trial² assigned 105 women aged 60–75 to Thai abdominal massage, prunes or routine care; 98 completed. Family members delivering massage received two or three training sessions, demonstrated their technique and had weekly follow-up calls.²

Massage produced a larger decrease in constipation scores. But the prune comparison was 50 g only twice weekly, so this cannot establish superiority over daily prunes. Participants knew their treatment, and analysis excluded dropouts.²

The paper also describes 20-minute sessions twice weekly for eight weeks, then says completion required 24 sessions. Twice weekly would give 16. That unresolved discrepancy makes the schedule difficult to reproduce. Side effects were not systematically monitored. Treat this as support for further study, rather than a dependable home-treatment recipe.²

Improved symptoms did not necessarily mean fewer laxatives

An earlier Swedish randomized trial included 60 people. One group added massage to previously prescribed laxatives; the other continued those prescriptions alone. Assessments ran to eight weeks.³

Massage improved constipation symptoms, abdominal pain and bowel-movement frequency compared with control, but the change in laxative use did not differ significantly. The investigators described massage as a possible complement to medication. This study does not support replacing a prescription with massage or reducing a dose without discussing it with the prescriber.³

A larger review does not settle which device to buy

A 2026 review combined 35 publications involving 1,965 adults. It found improvements in bowel frequency and quality of life, but pooled randomized trials alongside single-arm studies and other designs. Results of manual massage varied substantially. Comparisons across different studies cannot establish that a machine works as well as a trained person’s hands for the same patient.⁴

One author disclosed employment by usMIMA, which makes a device evaluated in the review. That connection warrants attention when reading its favorable discussion of automated massage.⁴

Safety reporting was incomplete: 15 studies covering 760 people assessed adverse events, reporting 48 people with mild, self-limiting events. Twenty studies of manual massage did not address adverse events. An absence of recorded harm in those papers is not proof that every technique suits every abdomen.⁴

Ask for instruction before trying firm pressure

Cambridge University Hospitals, in its UK patient guidance, describes gentle strokes and kneading lasting about 10–20 minutes, performed by the person or a helper. Ask a bowel-care nurse or pelvic-health physiotherapist to demonstrate an appropriate technique and watch you practise. A written leaflet can support that instruction.⁵

The hospital does not recommend abdominal massage during pregnancy, or with a history of malignant bowel obstruction or an abdominal growth, Crohn’s disease, ulcerative colitis, unstable spinal injury, recent scarring or abdominal surgery. It advises care with an abdominal hernia. Discuss these circumstances before trying massage; increasing pressure is not a substitute for an assessment.⁵

Keep a bowel record that captures more than frequency

The chapter “Three and Three” in Bloated by Dinner examines stool form, straining, incomplete emptying and changes from your usual pattern. That gives you several things to record when discussing constipation treatment, rather than judging success by a daily bowel movement alone.

For a review appointment, bring a dated record of bowel movements, stool form, difficulty passing stool, discomfort, massage sessions and medicines used. Agree beforehand when to review the routine. Recording several changes together will not tell you which one caused improvement, so include any new laxative, supplement or dietary change too.

Get medical advice if constipation persists despite self-care. NIDDK, the US digestive-health institute, advises seeing a doctor right away for constipation with rectal bleeding or blood in stool, constant abdominal pain, inability to pass gas, vomiting, fever or unintended weight loss. Do not spend several weeks testing massage in place of having those symptoms assessed.⁶
