New preliminary studies this week show the long-term benefits of bariatrics or weight loss surgery. Studies have shown that people who compare surgery to obesity are less likely to develop certain cancers within a decade and have not had surgery. Those who died of cancer also died less.

The study was conducted by researchers at the Gundersen Lutheran Health System in Wisconsin. By 2001, they had reviewed the medical records of more than 1,000 patients who had undergone surgery at their hospital. These patients were compared to a control group of approximately 2,000 non-surgical patients (BMI) who matched factors such as gender, age, and baseline body mass index. Their cancer-related effects followed for 10 years.

In those years, the probability of a new cancer diagnosis was significantly lower than in the surgical group (5.2% vs. 12.2%). The largest reductions were in breast cancer (1.4% vs. 2.7%), female reproductive cancer (0.4% vs. 2.6%), and kidney cancer (0.10% vs. 0.80%). ) was observed for. In addition, the 10-year survival rate of cancer patients in the bariatric group was 92.9%. 80.6% for control patients.

There were results presented has been published this week at the Annual Meeting of the American Society of Metabolic and Bariatric Surgery (ASMBS) and in a peer-reviewed journal that is an important part of the scientific process. However, this is the latest study to show that patients with bariatrics have better health outcomes after surgery, including a reduced risk of cancer. In fact, a separate paper presented This week, ASMBS surgical patients were found to be 37% less likely to develop bowel cancer.

“This study also sheds light on the various cancers that can lead to obesity, as well as the extent to which bariatric surgery can reduce the risk of cancer,” Gundersen Lutheran general and bariatric surgeon Jared Miller wrote in an email to Gizmodo. “We believe that this information is very important to inform other health professionals about the impact of bariatric surgery on cancer, which is specific to each specialty.”

There are different types of bariatric surgery, but most of them usually involve the complete restoration of the digestive tract. Then patients try to lose a lot of weight and maintain it – this is a very difficult thing. to perform by changing the typical diet and lifestyle. Many of the cancer-related benefits of surgery come from weight loss, Miller says, but there may be other changes in the body. He noted that obesity is associated with increased inflammation, changes in the intestinal microbiome and changes in hormone levels. can contribute to cancer risk and survival.

The results of the study, at least for this reason, show the ongoing value of bariatric surgery capable and ready To achieve it, they can influence the treatment of obesity in general. It has been in recent years medicines developed This seems to be more effective than previous treatments to help people lose weight. In May, Eli Lily’s Munjaro was approved for type 2 diabetes and she will be approved for obesity later this year or next year. There are large-scale tests has been found People who took Munjaro lost 20% or more of their weight – slightly lower than the average weight loss seen in typical bariatric surgery.

So far, the long-term health benefits of this new pharmaceutical treatment are still in question. Although interventions such as diet, exercise, and medication help people lose weight, Miller notes that only bariatric surgery has shown such a lasting improvement in health.

ASMBS President Shanu Kotari, who has nothing to do with the study, said it would take time to determine if these drugs could match the surgical potential in treating or preventing obesity-related conditions such as cancer.

“Future research should be done to see if pharmacological interventions can reduce the risk of cancer like bariatric surgery to lose weight,” he said in an email to Gizmodo.
