This is shown by the Swedish Obese Subjects study carried out at the Sahlgrenska Academy, University of Gothenburg, Sweden, involving 104 patients who were operated on despite their BMI being “too low”. As a result, the risk of developing diabetes was reduced by 67 percent.
In order to meet the current selection criteria for weight-loss surgery, Swedish patients must have a body mass index (BMI) above 40 for healthy patients, or above 35 in combination with other risk factors such as type 2 diabetes.
However, these selection criteria have not been devised in a scientific manner, and need to be improved. This is the opinion of researchers at the Sahlgrenska Academy, University of Gothenburg, who have shown in a new study that weight-loss surgery also offers significant health benefits for patients who do not meet today’s criteria.
In the study, which has been published in Diabetes Care, the researchers from Gothenburg have monitored 104 patients who had weight-loss surgery before the current criteria were established, and who would not have been offered the operation today. The study shows that, 15 years after the procedure, these patients had a 67 percent lower risk of developing diabetes compared with a control group who were not operated on.
“The effect was the same as for patients who meet the current criteria,” explains researcher Kajsa Sjöholm from the Sahlgrenska Academy, University of Gothenburg. “In other words, there is no proof that weight-loss surgery has a greater preventive effect against diabetes for patients who exceed today’s BMI limit than for those who don’t.”
The study also shows that weight-loss surgery reduces the risk factors for cardiovascular disease among patients who are not currently eligible for this surgery.
With reference to previous results published in the SOS study at the University of Gothenburg, which showed that weight-loss surgery generally results in a long-lasting reduction in weight and reduces the risk of diabetes, heart disease, stroke, cancer and premature death, the researchers from Gothenburg believe that today’s selection criteria should be re-evaluated.
According to the researchers, strict BMI limits can lead to patients with a high risk of future disease who would benefit from treatment being denied surgery. Previous research findings show that the selection can be improved by analysing patients’ insulin and glucose values.

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.
Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
