Effects of Surgical and Dietary Weight Loss Therapy for Obesity on Gut Microbiota Composition and Nutrient Absorption

Figure 2

Human gut microbiota changes on the taxonomic species level induced by weight loss therapy for morbid obesity: (a) laparoscopic sleeve gastrectomy (LSG) and (b) very low calorie diet (VLCD). Shown are all bacterial species for which changes were significantly defined as a P(corr) > 0.75 or <−0.75 derived from OPLS-DA models.
