Background: Most of the world's population underwent compulsory health quarantine during the pandemic of Coved 19 virus that led to a change in lifestyle and caused a negative psychological effect. Objective: This study aims to assess the effects of different variables in lifestyle on the weights of obese patients who underwent sleeve gastrectomy compared to obese patients without surgery during 3 months of the health quarantine. Methods:The study included 2 groups, the first one included 85 patients who underwent sleeve gastrectomy before more than 6 months since the date of the start of the health quarantine in Iraq. The second group included 75 patients with obesity but were not subjected to sleeve gastrectomy or any other bariatric surgery. Patients were contacted through social media 3 months after starting the health quarantine where the complete ban has ended, Patients were asked to answer an information form to assess their weight, nutritional state, commitment to diet, exercise performance and psychological mood during the quarantine time. A statistical study was conducted between the two groups. Results: weight gain was recorded in both groups, although it is less in sleeved patients, the difference is not statistically significant. Physical exercises, altered diet habits, altered types of food were recorded in both groups and again without significant difference. Stress and altered sleep pattern which occurred in the quarantine may be attributed to weight gain. The study fails to show a significant relation to the special type of food. Conclusion: weight gain recoded in Quarantine and this is a major health problem that may affect the life of obese patients.
