Weight Loss Surgery Quiz Answer Top Questions

Weight Loss Surgery Quiz

Weight loss surgery, also known as bariatric surgery, helps severely obese people lose weight by reducing stomach size and changing the digestive tract. This leads to fewer calorie intake. Bariatric procedures can also affect intestinal hormones to reduce hunger and increase feelings of fullness.

Safest Weight Loss Surgery

  • Gastric bypass (Roux-en-Y gastric bypass, or RYGB): Part of the stomach is closed off and connected to the small intestine. This results in the fastest and greatest weight loss, but it is the riskiest procedure.
  • Gastric sleeve (sleeve gastrectomy): A large portion of the stomach is removed, leaving a narrow "sleeve." This is a safer option than gastric bypass.
  • Duodenal switch surgery: A combination of a gastric sleeve and gastric bypass surgery.
  • Laparoscopic adjustable gastric band (lap-band): A silicone ring with an expandable balloon is inserted around the top of the stomach to create two compartments. This is the least invasive procedure.
  • Gastric balloon: A balloon is inserted into the stomach, reducing space for food. It’s safe but does not result in significant weight loss.

Eligibility for Weight Loss Surgery

A person’s body mass index (BMI) determines eligibility for weight loss surgery. A BMI of 30 or greater is considered obese.

  • Your BMI is above 35 and you have an obesity-related medical problem.
  • Your BMI is above 30 and you have certain medical conditions.

Cost of Weight Loss Surgery

The cost of weight loss surgery varies depending on the procedure and location. Insurance coverage varies as well.

The average cost nationally ranges from $14,000 to $23,000, with sleeve gastrectomy being less expensive and gastric bypass being more expensive.

Diet After Weight Loss Surgery

Following weight loss surgery, you will progress from a clear liquid diet to full liquids, pureed foods, and then soft solid foods. Emphasize protein sources, carbohydrates, and fiber.

Consult with a nutritionist once you reach your goal weight. High protein, low fat, and low-calorie foods are recommended. You may need vitamin and mineral supplements due to reduced nutrient absorption.

Hospital Stay After Weight Loss Surgery

Patients spend about two to five days in the hospital after weight loss surgery, depending on the procedure. Longer stays may occur due to complications. Follow-up visits are scheduled post-op.

Avoid strenuous activities and heavy lifting for three to six weeks after surgery. Prevent blood clots by avoiding long periods of sitting or standing still.

Expected Weight Loss After Surgery

Patients can lose 50 to 80 percent of their excess weight after weight loss surgery. The amount varies based on the procedure and individual factors.

  • Duodenal Switch: 80% loss of excess weight
  • Gastric Bypass: 70% loss of excess weight
  • Gastric Sleeve (Sleeve Gastrectomy): 60% loss of excess weight
  • Gastric Band (Lap Band): 50% loss of excess weight
