BODY-Q eating-related symptoms following sleeve gastrectomy

Background: Recent data describing gastrointestinal (GI) symptoms experienced by patients after bariatric surgery is lacking, and previous studies in sleeve gastrectomy patients have been limited in scope of follow-up time or extent of GI symptoms examined. We sought to characterize the prevalence and time course of patient-reported eating-related symptoms in sleeve gastrectomy patients.

Methods: From July 2020 to July 2021, sleeve gastrectomy patients seen at three Boston area hospitals received electronic surveys and prospectively reported GI symptoms using the BODY-Q eating-related symptoms scale. Descriptive analyses were performed for patient demographics and symptom prevalence. Chi-square tests were used to compare prevalence of eating-related symptoms between follow-up time intervals.

Results: 491 sleeve gastrectomy patients completed postoperative surveys with mean follow-up time of 1.9 years. Mean age was 46.6 years, and 81.3% were female. The most reported GI symptoms overall included constipation (56.6%), bloating (54.0%), heartburn when standing (41.5%), and heartburn when lying down (39.9%) while the least commonly reported symptoms were palpitations (16.3%), low blood sugar (15.7%), and emesis (15.1%). At greater than 12 months, the most reported symptoms similarly included bloating (60.3%), constipation (53.2%), and heartburn while standing (46.0%). When comparing prevalence of eating-related symptoms across follow-up time intervals from < 1 to > 12 months, patients reported a significant decrease in constipation, abdominal pain, and nausea over time (p = 0.012, p < .0001, p = 0.03, respectively).

Conclusion: Patients experience both upper and lower GI symptoms following sleeve gastrectomy, and symptoms, including bloating, constipation, and heartburn may persist through long-term follow-up. These patient-centered measures add value by guiding preoperative counseling, informing postoperative expectations, and providing real-time clinical feedback for bariatric surgery patients.
