Experience with Tirzepatide and Weight Management During and After a Clinical Trial in Japanese Patients with Obesity Disease: A Qualitative Study.
Editor's note
This is a small qualitative exit-interview study (29 Japanese participants) exploring lived experience during and after the SURMOUNT-J tirzepatide trial — not an efficacy study. Its value is in texture, not effect sizes: most participants described appetite loss and changed eating habits on treatment, positive feelings about weight loss, and a wish to continue therapy; after the trial ended, many maintained eating changes but not exercise habits, and about two-thirds reported poorer appetite control. Qualitative work of this size cannot be generalised and is subject to recall and selection bias, and self-reported experience is not a clinical outcome. The findings echo a familiar pattern — weight-related benefits from incretin therapy tend to attenuate once treatment stops. Read it as a window into patient experience and unmet support needs, complementing rather than substituting for the quantitative SURMOUNT-J results.
Plain-language abstract
This study explored how people felt about taking tirzepatide, rather than measuring how much weight they lost. Twenty-nine adults in Japan who completed the 72-week SURMOUNT-J trial were interviewed online about their experiences during and after the study. While on tirzepatide, about three-quarters reported reduced appetite and conscious changes to their eating habits, most had positive feelings about losing weight, and three-quarters wanted to keep taking the medication. Many enjoyed practical changes like being able to choose new clothes and moving more easily. After the trial ended, about half kept up their new eating habits, but many could not maintain exercise changes, and roughly two-thirds found their appetite harder to control again. The interviews pointed to a need for better information and support connecting people with obesity to appropriate care. Because this was a small interview-based study, its findings describe personal experiences and cannot be assumed to apply to everyone.
