A weight loss of only 5 to 10% would increase the life expectancy of people suffering from obesity and diabetes. This finding is valid when weight loss is achieved through surgery.
Type 2 diabetes is strongly linked to weight: obese people are more at risk of suffering from it. Obesity like diabetes can have consequences on health, losing weight can help to avoid them. In Annals of surgery, scientists show that weight loss through surgery is more effective in reducing the risks associated with these pathologies. According to them, losing 5 to 10% of your weight is associated with a better life expectancy and better cardiovascular health.
An observational study
To reach these conclusions, the researchers carried out an observational study on more than 7,000 patients at the clinic in Cleveland, USA: 1,223 had type 2 diabetes and obesity and underwent surgery to lose weight ; 5978 suffered from the same pathologies but had not been operated on. Using statistical tools, the research team identified the minimum weight loss to reduce the risk of death and cardiovascular disorders.
Less weight loss
“After metabolic surgery, the risk of death and major cardiac complications decreases after weight loss by 5% and 10% respectivelyexplains Ali Aminian, lead author of the study. While in the group who did not undergo surgery, the risk of death and major cardiac complications only decreased from 20% weight loss“According to the study, the health effects of surgery are significant and not only related to weight loss. The researchers will continue to explore the physiological effects of weight loss by surgery, particularly on the gastrointestinal system. -intestinal, but also on the secretion of hormones and the microbiome.
More and more operations
Obesity surgery, also called bariatric surgery, is recommended in extreme cases and when other solutions have not worked. Several techniques exist: the installation of a gastric band, the partial ablation of the stomach or the derivation of the digestive tract, called Bypass. In recent years, the number of operations has increased sharply: there were 2,800 in 1997 compared to 59,300 in 2016. According to direction of research, studies, evaluation and statistics, women represent 80% of those operated on. Most of the patients are between 25 and 54 years old, but for several years, more and more teenagers have been operated on like the elderly.
