How effective is Bariatric Surgery?


“The only way you can truly get more out of life for yourself is to give part of yourself away.”


The actual weight a patient will lose after the operation depends upon several factors. These include:


  • Patient’s age
  • Weight before surgery
  • Overall condition of patient’s health
  • Surgical procedure
  • Ability to exercise
  • Commitment to maintaining dietary guidelines and other follow-up care
  • Motivation of patient and cooperation of family, friends, and associates

A recent study established the following criteria for successful bariatric surgery: the ability to achieve and maintain loss of at least 50 percent of excess body weight without having significant adverse effects. Clinical data will vary for each of the different procedures mentioned in this site.


Results may also vary by surgeon. Ask your doctor for the clinical data stating their results of the procedure they are recommending.


Clinical studies show that, following surgery, most patients lose weight rapidly and continue to do so until 18 to 24 months after the procedure. Patients may lose 30 to 50 percent of their excess weight in the first six months, and 77 percent of excess weight as early as 12 months after surgery.


Patients with higher initial BMIs tend to lose more total weight. Patients with lower initial BMIs will lose a greater percentage of their excess weight and will more likely come closer to their ideal body weight.


Patients with Type II Diabetes tend to show less overall excess weight loss than patients. Many patients with Type II Diabetes, while showing less overall excess weight loss, have demonstrated excellent resolution of their diabetic condition, to the point of having little or no need fro continuing medication.


Bariatric surgery also has been found to be effective in improving and controlling many obesity-related health conditions. A comprehensice clinical review of bariatric surgery data showed that patients who underwent a bariatric surgical procedure experienced complete resolution or improvement of their co-morbid conditions including diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea etc.
