How Effective is Surgery?

Success = Losing 50% of Excess Body Weight

Successful Weight Loss

Weight loss surgery is considered successful when a patient loses 50% or more of excess body weight (the "overweight") and keeps the weight off for at least five years. Several factors influence a patient's success:

  • Age
  • Pre-surgery weight
  • Overall health
  • Surgical procedure
  • Ability to exercise
  • Commitment to diet, exercise, and follow-up care
  • Motivation
  • Cooperation of family, friends, and associates

Clinical studies show that, in general, patients:

  • Lose weight for 18-24 months after the procedure
  • Lose 30-50% of excess weight in the first six months and 77% of excess weight within 12 months of surgery
  • Maintain a 50-60% loss of excess weight 10-14 years after surgery
  • With higher initial BMIs lose more total weight
  • With lower initial BMIs lose a greater percentage of excess weight and come closer to their ideal body weight
  • With Type 2 diabetes lose less excess weight than patients without Type 2 diabetes
  • Very few people reach their ideal body weight—this is not the goal of bariatric surgery

Bariatric Surgery Health Benefits

  • Bariatric surgery can offer you a new lease on life. Following surgery, many patients lose weight rapidly and continue to do so for 18 to 24 months after the procedure.
  • Bariatric surgery is known to be one of the most effective and longest lasting treatments for obesityrelated conditions. Studies found that gastric bypass surgery reduced the total number of obesity-related conditions such as migraines by 57%; depression by 55%; sleep apnea by 74-98%; asthma by 82%; cardiovascular disease by 82%; hypertension by 52-92%, and GERD by 72-98%. In some cases, diabetes can be eliminated after bariatric surgery.
  • Most individuals who have had bariatric surgery feel better, engage in recreational and physical activities, and have more self-confidence than they did prior to surgery. Our goal is to help our patients accomplish this.
