Probiotics are the "good" bacteria found in yogurt and in dietary supplements that aid digestion.
The Stanford University School of Medicine study included 44 patients who had Roux-en-Y gastric bypass surgery and were randomly assigned to either a probiotics group or a control group. Both groups received the same bariatric medical care and nutritional counseling and both were allowed to consume yogurt, a natural source of probiotics. Patients in the probiotics group also took one pill per day of a probiotics supplement.
After three months, the probiotics group had a 47.6 percent weight loss, compared with 38.5 percent in the control group. Patients in the probiotics group also had higher levels of vitamin B-12 three months after surgery than those in the control group -- 1,214 picograms per milliliter as opposed to 811 picograms per milliliter, a significant difference since B-12 deficiency is common after gastric bypass surgery.
