40 patients meeting the criteria for obesity surgery are enrolled. Fecal microbiota transplantation (FMT) will be administered in gastroscopy 6 months before obesity surgery. 20 of the patients will receive a fecal transplant of a thin donor and 20 will receive placebo - a transplant made of their on feces. Changes in weight, laboratory values, general well being and stool microbiota will be measured up to one year after the surgery; one and a half years after FMT. The hypothesis is that FMT and the change in gut microbiota will help to reduce and maintain lower weight.
