Changes in circulating hormone levels after gastric bypass have been hypothesized to produce reductions in food intake and body weight in obese patients. However, these findings remain controversial, and the exact mechanisms by which gastric bypass surgery reduces food intake and body weight have yet to be elucidated.
Intestinal bypass surgery can lead to loss of weight effectively, but it can also lead to various complications that should not be neglected. About half of the patients who received this surgery need rehospitalization to manage the complications. [5] The expected outcomes and possible risks of the intestinal bypass surgery are shown as follows:
Roux-en-Y gastric bypass. Gastric bypass is the most frequently employed technique for weight reduction, the abnormal absorption in the intestines and the physical restriction of the stomach. [1] [2] The types of surgeries can be categorized by the effects and the changes made.
After performing gastric bypass surgery, the two hormones related to obesity, leptin and insulin, fall in levels and while lose weight. [13] Roux-en-Y (RYGB) offers two surgical approaches for processing: an open technique or the laparoscopic technique. The majority of cases are still performed with laparoscopy. [13]
Schematic of gastric bypass using a Roux-en-Y anastomosis. The transverse colon is not shown so that the Roux-en-Y can be clearly seen. The variant seen in this image is retrocolic, retrogastric , because the distal small bowel that joins the proximal segment of stomach is behind the transverse colon and stomach.

Gastrectomy, gastric bypass surgery, diabetes, esophageal surgery, absent or inefficient pyloric sphincter, pyloric stenosis Dumping syndrome occurs when food, especially sugar, moves too quickly from the stomach to the duodenum —the first part of the small intestine—in the upper gastrointestinal (GI) tract .
Gastric bypass: A weight-loss procedure that includes separating the stomach into an upper pouch that is smaller and a lower pouch that is bigger. Then, a section of the stomach and small intestine are skipped in favor of rearranging the small intestine to link to both pouches.
