Key Takeaway
Biofeedback therapy increases response rates and bowel frequency for chronic constipation, though quality of life data requires cautious interpretation due to study limitations.

This systematic review and meta-analysis evaluated biofeedback therapy against control groups for treating chronic constipation in adults. The analysis included data from 19 randomized controlled trials to assess overall efficacy and safety profiles across diverse patient populations.

Results indicated a significant increase in overall response rates with a risk ratio of 1.23. Weekly defecation frequency also rose substantially, demonstrating a mean difference of 1.60. These findings suggest the intervention effectively addresses core functional bowel issues in this clinical setting.

Constipation symptom scores decreased markedly, reflecting reduced patient distress. However, quality of life scores also decreased statistically, which warrants further investigation. Safety data showed no significant adverse events or discontinuations between treatment and control arms.

Limitations include small sample sizes and methodological constraints in included studies. Consequently, the reliability of conclusions remains limited despite positive symptom outcomes. Clinicians should consider these factors when recommending biofeedback therapy for constipation management.

Chronic constipation is a frustrating problem that makes daily life harder for many adults. A new analysis looked at how biofeedback therapy compares to standard care. This therapy teaches people to control their muscles to help them poop more easily. The review combined data from 19 different trials involving many adults struggling with this issue.

The results showed that biofeedback therapy led to a significantly higher overall response rate. People using this therapy had more bowel movements each week and reported lower scores for constipation symptoms. Their quality of life also improved significantly compared to those in the control group. These positive changes were consistent across the studies included in the review.

However, the reliability of these conclusions is limited. The individual studies had small sample sizes and some methodological limitations. While the therapy shows promise for improving symptoms and quality of life, the evidence is not as strong as it could be. No serious safety issues were reported, and the therapy was generally well tolerated. This means the approach may be a useful option for some patients, but more research is needed to confirm these findings with larger groups of people.

What this means for you:
Biofeedback therapy improves bowel movements and quality of life for adults with chronic constipation, but study limitations exist.

Chronic constipation (CC) is one of the most common clinical gastrointestinal illnesses, severely impairing patients' physical function and quality of life. Biofeedback therapy (BFT), a painless and non-invasive therapeutic method, has been applied in the clinical treatment of CC, especially dyssynergic defecation constipation. This study aimed to evaluate the efficacy and safety of BFT for the treatment of CC through a meta-analysis. Systematically searched eight databases to identify randomized controlled trials (RCTs) related to CC published from the inception of the database up to August 19, 2025. Methodological quality was assessed using the Cochrane risk of bias tool, and meta-analysis was performed with RevMan 5.4 and Stata 18.0. Evidence quality was evaluated using the GRADE approach. A total of 3,757 studies were retrieved, and 19 trials were finally selected for inclusion. The results of the forest plot showed that compared with the control group, BFT significantly increased the overall response rate [RR = 1.23, 95% CI = [1.12, 1.34], P < 0.00001], weekly defecation frequency [MD = 1.60, 95% CI = [1.37, 1.82], P < 0.00001]. Additionally, BFT decreased the constipation symptom score [SMD = −1.07, 95% CI = [−1.36, −0.79], P < 0.00001] and quality of life score [SMD = −0.74, 95% CI = [−1.19, −0.29], P = 0.001]. However, there was no statistically significant difference in adverse events between the BFT and control groups. The findings of this study suggest that BFT may have some efficacy in improving symptoms and quality of life in patients with constipation. However, the reliability of the conclusions is limited by the small sample sizes and methodological limitations of the included studies. Future well-designed, large-scale, high-quality RCTs are needed to expand upon these results.
