Morbid Obesity | Probiotics Improve Gastrointestinal Symptoms After Roux-en-Y Gastric Bypass: A Prospective Randomized Trial

Morbid Obesity research study

What is the primary objective of this study?

Obesity has been a global epidemic. Currently, bariatric surgery has been recognized as the only successful treatment for morbid obesity. Laparoscopic gastric bypass (LGB) is the leading bariatric surgery worldwide including Taiwan, it's resulted in significant weight loss and resolution of metabolic co-morbidities in morbidly obese patients . However, annoyed Gastro-Intestinal (GI) symptoms are a common complaint after gastric bypass like foul smell flatus, oil flatus and over flatus. The aim of this study was to determine whether probiotics would improve annoyed GI symptoms after gastric bypass. Probiotics are live microorganisms (in most cases, bacteria) that are similar to beneficial microorganisms found in the human gut. They are also called \"friendly bacteria\" or \"good bacteria.\" Probiotics are available to consumers mainly in the form of dietary supplements and foods.
