Weight-Loss Surgery: My Wife Made Me Lose It




Weight-loss surgery options

Weight-loss surgery, also called bariatric surgery, is a major procedure. It changes the way your body digests food. Weight-loss surgery may be appropriate if you have tried other methods to lose weight but remain severely obese, or if you have a serious disease caused or made worse by obesity. It may be appropriate for people with a BMI of 40 or greater, or about 100 pounds overweight for men and 80 pounds for women, or for people with a BMI of 35 or greater if they have serious medical conditions such as type 2 diabetes, hypertension and sleep apnea, to name a few.

LVHN offers three types of weight loss surgery.

  • Adjustable gastric band (LAP-Band®, Realize™)
  • Gastric bypass (Roux-en-Y)
  • Sleeve gastrectomy (Gastric sleeve surgery)
Adjustable gastric banding (LAP-Band®, Realize™)

Laparoscopic | Effect: Restriction

  • May help you lose 50 to 60 percent excess body weight within three years
  • Prolonged sense of fullness after small meals

Adjustable gastric banding is performed laparoscopically through small incisions. Your surgeon will place a silicone band around the top portion of the stomach, leaving a smaller pouch available for food. The small pouch means you will feel full after eating only small amounts of food, helping you lose weight. The band’s volume can be adjusted to regulate the amount of food restriction. If necessary, the procedure can be reversed.

Gastric bypass (Roux-en-Y) surgery

Laparoscopic | Effect: Malabsorption and restriction

  • May help you lose up to 80 percent excess body weight within five years
  • Is the most common type of weight-loss surgery
  • Our board-certified surgeons have performed more than 1,100 gastric bypass surgeries since our program began.

During laparoscopic gastric bypass surgery, your surgeon will reform your stomach to create a smaller stomach pouch. A section of the small intestine will attach directly to the pouch. This allows food to bypass a portion of the small intestine that absorbs calories and nutrients. You will feel fuller sooner and eat less because your stomach pouch holds less food. Gastric bypass also may effectively treat acid reflux disorder because the acid-producing part of the stomach is separated from the esophagus.

Sleeve gastrectomy (Gastric sleeve surgery)

Laparoscopic | Effect: Restriction

  • Can help you lose up to 70 percent excess body weight within two years
  • Lower risk for vitamin deficiency
  • Reduces production of the appetite-stimulation hormone ghrelin

The gastric sleeve procedure removes about 75 percent of your stomach through laparoscopic surgery. What remains is a narrow tube (or sleeve) of stomach. This limits the amount of food you can eat and helps you feel full sooner. It also allows for normal digestion and absorption, so you get the nutrients and vitamins you need. During the procedure, the part of your stomach that curves outward, called the fundus, will be removed.

The fundus contains most of the glands in your stomach that secrete an appetite-stimulating hormone called ghrelin. Because ghrelin may be partly responsible for making you feel hungry, removing this part of your stomach may help you lose weight afterward.
