Understanding weight regain: Insights from Saudi patients on factors influencing post-metabolic and bariatric surgery outcomes: A qualitative study.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWeight restoration is still possible even if Metabolic and Bariatric Surgery is the most efficient therapy for extreme obesity. While the non-controllable causes of weight regain have been investigated, the controllable causes of weight regain have received less attention. PURPOSE: The aim of this study was to explore the factors contributing to weight regain after Metabolic and Bariatric Surgery as perceived by patients.
methodsA qualitative descriptive research design used, where semi-structured interviews were carried out.
resultsThe thematic analysis gave rise to five themes. The first theme was titled "Economic challenges," and it highlighted the challenges experienced by the patients in maintaining a healthy diet. The second theme, "Emotional instability and occupational stress," reflects the psychological concerns that patient's experience, which hinder them from keeping a healthy lifestyle. The "Social influence" theme focused on the environment of the patients, which enhanced cravings, and the "Lack of support" theme highlighted the negative perspective of the social network of the participants towards the patients' surgery and desired lifestyle. Finally, the "False beliefs and decreased physical activity" theme focused on how the perception of the patients towards the results or effects of the surgery led to reduced physical activity, which they perceived as leading to weight gain.
conclusionDespite being successful, weight regain can still happen following bariatric surgery. In order to promote long-term weight loss sustainability, the results of this paper reinforce the idea that persons who have had Metabolic and Bariatric Surgery ought to be educated of the controllable variables linked with weight rebound, future research address the long term effect and the weight control factors following the surgery are highly recommended.
