Bariatric Surgery reduces severity of corona virus infection in individuals suffering from obesity.
Previous history of bariatric surgery significantly reduces risk of hospital admission, intensive care treatment and ventilator requirement in covid positive patients suffering from obesity.
Obesity significantly increases covid related mortality and morbidity because of defective immune response to infections. Obesity with BMI > 30 kg/m2 is an independent risk factor for COVID-19. Additional presence of diabetes further aggravates the risk.
Bariatric surgery results in long term and significant weight loss and diabetes remission. It also normalises functions of severy body systems including immune system. Those who underwent bariatric surgery if affected with corona virus, will have asymptomatic or mild infection and the hospital admissions are low. So bariatric surgery offers protection against severe COVID – 19.
