The Corona Virus Disease 2019 (COVID-19) pandemic has impacted the functioning of health systems, imposing the need for adaptations. Elective surgeries also needed to adapt, and research has shown higher mortality in newly infected surgical patients after or during procedures. Thus, was recommended the suspension of elective surgeries during the pandemic. Early studies evaluating the effect of COVID-19 pandemic on bariatric surgery have reported a substantial reduction in procedures performed.

This retrospective study evaluated the impact of the suspension of bariatric surgeries for a Brazilian Health Maintenance Organization: UNIMED-BH, based on the analysis of data from before and during the pandemic of COVID-19.

There were 2,641 bariatric procedures conducted in 2019 with a 14.1 percent reduction in volume to 2,314 procedures in 2020. In 2021, there were 2,813 bariatric procedures and 1,700 procedures were observed from January to August 2022. Therefore, it appears that in 2022 the demand for bariatric procedures will be similar to the year 2019, which was before the COVID-19 pandemic.

From the analysis of the data, a decrease in bariatric surgical volume was evidenced during the year 2020 when compared to 2019. Post-pandemic, monitoring is necessary to assess whether the system was able to meet the demand for bariatric surgical procedures.
