Bariatric surgery results in long-term microbial depletion. Bariatric surgeries, adjustable gastric banding and Roux-en-Y-gastric bypass may improve gut bacteria richness in some, but microbial abundance remains depleted even up to 5 years after surgery. This study illustrates the need for microbial interventions, such as dietary interventions, prebiotic/probiotic supplementation, and possibly fecal microbiota transplantation before and/or after surgery for severely obese patients. Gut

→Takeaway: The study found very low microbial gene richness in 75% of severely obese patients. Low microbial gene richness also affects the general population – 40% of overweight/moderately obese individuals and 23% of the general population have very low microbial gene richness, which is associated with insulin resistance, systemic inflammation, and type 2 diabetes. The number one way to improve microbial richness is to improve the fiber content and plant variety in your diet.
