Digestion is an essential process for acquiring nutrients for metabolism. Metabolism, the sum of anabolic and catabolic reactions that consume or produce energy, controls several important body parameters such as body weight. The proper interplay between metabolism and digestion is important, and when that fails, we have metabolic disorders, such as diabetes, food intolerance, or obesity. In particular, obesity has become a common, serious, and costly disease. Weight-loss surgeries or approaches can help lose weight and lower the risk of medical problems associated with obesity.
