II) The second news, is related with the fast normalization of blood sugar’s levels (98% of cases in less than 1 month), in patient with Diabetes type II -including insuline dependent- subjected to Roux in Y gastric bypass : RYGB (duodenum and more than 90% of stomach, extirpation). A team of scientists led by Francesco Rubino of the Catholic University of Rome, arrived to these conclusions after subjected to surgery to 7 diabetic type II, patients with and without overweight. Not a new study, because one knows other bigger : 22,094 patients, in those complete reversion of Diabetes Type II, was demonstrated in 84% of the cases, after being subjected to RYGB. Some hypotheses try to explain the phenomenon: 1) after the bypass, a persistent increment of glucagon-like (1 GLP-1, peptide normally in charge of diminishing the levels of blood sugar), would exist, 2) a persistent decrease of ghrelin would exist, a peptide that stimulates the appetite 3) when being eliminated the duodenum, the resistance to the action of the insulin, would be eliminated. Now that somebody offer similar although less aggressive surgeries to diabetics, we object the method, insisting in the realization of studies but detailed of the new physiologic rearrangements (hormonal and others), after the surgery, aspiring to manage the levels of sugar with rationality and medications. The bypass reduces the size of the stomach in but of 90% (usually able of expanding up to 1000 ml), being hardly 16 ml of residual capacity, with which the patient perceived (after the ingestion of small quantities of foods), stomach fullness, growing satiety and/or indifference to foods. Of another side, the small intestine converted (anatomical and physiologically), in a neo-stomach, is to the long unable to support the new functions, developing malabsorption of fatty, starches (on which germ act causing bad odor), minerals, soluble fat-vitamins and others.
