How Many People Have Died From Gastric Bypass Surgery?

February 8, 2024

The most common cause of death was sepsis (n=6) associated with anastomotic leak in 4 cases. Cardiovascular causes (n=3) including thromboembolism were the next most common causes of early death. The overall mortality rate was lower than that reported in previous studies (5,7,22,23).

Bariatric surgery involves reducing the size of your stomach or changing how food moves through your digestive tract to help you lose weight and control your appetite. It also helps to cure or reduce serious obesity-related health problems like diabetes, high blood pressure, and sleep apnea.

However, the surgery is not without risks. There are several different types of bariatric surgeries, but gastric bypass is a procedure that changes the way your body digests and stores food.

In the past, doctors used gastric bypass only on people who were severely obese and unable to achieve significant long-term weight loss with diet and exercise alone. But recently, doctors have started using the surgery more widely for moderately obese patients with a BMI of 35 to 40 or higher.

Despite the risks, many people who have gastric bypass surgery report long-term success and improved quality of life. The success of this type of weight loss surgery is dependent on making lifestyle changes, such as eating a healthy diet and taking nutritional supplements (multivitamins, iron, vitamin B12), avoiding alcohol and sweets, and staying physically active. If you’re considering gastric bypass, talk to your doctor about the risks and benefits.
