A new 40-year study shows that bariatric surgery increases life expectancy. The study of almost 22,000 people who had weight loss surgery in Utah found that bariatric surgeries reduce the risk of premature death, particularly from conditions related to obesity like cancer, diabetes, and heart disease.
Four weight loss surgeries (bariatric surgery) were analyzed between 1982 and 2018: gastric bypass, gastric sleeve, laparoscopic adjustable gastric banding (Lap-Band), and duodenal switch. Overall, the study showed that compared to people with similar weight, those who had weight loss surgery were 16% less likely to die from any cause. The decrease in deaths from obesity-related diseases like heart disease, cancer, and diabetes was even more significant. In fact, the decrease in deaths from cardiovascular disease was 29%, and decrease in deaths from cancers was an astonishing 43%. Deaths related to diabetes were decreased by an incredible 72% in patients who had surgeries compared to patients who did not have surgeries.
Gastric bypass is a classic procedure that creates a small pouch near the top of the stomach and attaches a part of the small intestine to that point. Gastric banding uses an elastic band around the top of the stomach to restrict food intake, while gastric sleeve involves removing two-thirds of the stomach. The duodenal switch is a complex procedure which reroutes the intestines and makes the stomach smaller.
The new study, published in the journal Obesity, confirms previous research that showed weight loss surgery can lead to long-term health benefits. It echoes the results of a 10-year study in Sweden which found that many people who had weight loss surgery were able to get in remission from diabetes, as well as a decrease in premature deaths. According to Dr. Eduardo Grunvald, a weight management expert from the University of California San Diego Health, it becomes easier to change one’s diet because the procedure changes the chemistry in the brain.
In conclusion, the 40-year study of bariatric surgery shows that weight loss surgery can have significant benefits for overall health and longevity. The results are consistent with previous research and emphasize the positive impact of bariatric surgery on long-term health. With proper counseling and support, weight loss surgery can be an effective solution for those looking to manage their weight and improve their overall health.
