Obesity has been studied as a worldwide epidemic in constant growth in recent decades. Bariatric surgery, in its various modalities, offers better life prospects for these patients. Basically these surgeries reduce the capacity of the gastric volume, controlling the food intake and consequently the weight reduction. Good habits can arise after weight loss, such as physical activity practices and balanced diet. This new lifestyle, and the remission of possible comorbidities associated with obesity, can alter the gut microbiota. The symbiotic relationship between these bacteria residing in the Gastrointestinal Tract (GIT), offer several benefits to man, such as: protection against infections, blocking colonization of pathogenic bacteria, pH control, enzymatic activities, absorption of nutrients such as ions and action in the production of some vitamins.
