Research Question: The Consequences of Malabsorption Syndrome in Post-Operative Gastric Bypass Patients Rationale: Gastric bypass operative procedures are a group of techniques that divides the stomach into a small upper pouch and a much larger lower pouch, then rearranges the small intestine so that it connects with both. There are a number of techniques to reconnect the intestine, but all lead to a considerable reduction in the volume of the stomach, also accompanied by an altered physiological response to food. Despite media advertising, these procedures are major surgeries that are usually only prescribed to treat morbid obesity, type-2 diabetes, serious hypertension or sleep apnea. Typically, 15% of patients have negative complications, and .5% dies within six months of surgery due to post-operative complications (USDHHS, 2009). The surgery itself, regardless of the technique, typically reduces the stomach by about 90%. When the patient eats even a small amount of food, the first response is stretching of the wall of the stomach pouch, which then stimulates nerves that tell the brain the stomach is full. The patient feels as if they ate a large meal with only a tiny amount of food, also teaching the patient to eat slowly and many very small meals. Recent research shows that changes in food intake are only partially responsible for weight loss, with no real evidence in most patients of significant malabsorption of calories. Instead, the research shows that the surgery
