About Weight Loss Surgery

Bariatric Surgery is Weight Loss Surgery

Bariatric surgery is the formal medical name for weight loss surgery. The word “bariatric” comes from the Greek word “baros” meaning weight and “iatros” meaning physician. Bariatric surgery is not cosmetic surgery! It is not liposuction! Bariatric surgery changes your digestive system so that your body takes in fewer calories. This changes your body’s energy balance so that you eat fewer calories than you burn, resulting in gradual, long-lasting weight loss!

How Does Bariatric Surgery Work?

Weight loss operations work to help you lose weight in 3 ways:

  • Restriction: The functional size of the stomach is reduced. This helps you to feel full after eating a smaller meal.
  • Decreased Absorption: The gastric bypass and the biliopancreatic diversion-duodenal switch (BPD-DS) both bypass some of the intestine. This limits the body’s absorption of calories.
  • Decreasing Hunger: Your stomach makes a hunger-causing hormones called ghrelin (pronounced “greh-lin”). Bariatric surgery may decrease the amount of ghrelin that your stomach produces. The result? You feel less hungry!

Surgery for Obesity: One Size Does Not Fit All!

The operation that works best for one person may not be the best for someone else. This is why it is necessary to speak with a bariatric surgeon to identify which operation is best for you.
