How does weight loss surgery work for patients with type 2 diabetes? There are no clear answers yet but doctors are carrying out an ongoing research. For instance, a recent study of more than 600 patients showed that 78 % of people had a total resolution of their diabetes after the procedure.
So far bypass surgeries proved to be more efficient than the surgeries that only “tighten” the stomach. Although blood glucose levels are likely to decrease with any kind of weight loss, the improvement after the surgery appears surprisingly quickly. This may have something to do with the reconfigured anatomy but scientists are not too certain whether it is due to the GLP-1 hormone, the inhibition of an agent that stimulates the appearance of high blood glucose, or the reduced calorie intake.
