Bariatric surgery: pros and cons

Gastric bypass and other weight-loss surgeries involve making changes to your digestive system to help you lose weight. What are bariatric surgery: pros and cons? Which is the best one for you? 

Bariatric surgery isn’t for everyone who is severely overweight. You may need to meet certain medical guidelines to qualify for weight-loss surgery.

Consider that this type of surgery is done when you have serious health problems because of your weight, and exercise or diet haven’t worked. In general, it could be an option in certain cases of obesity or extreme obesity if: 

  • Your body mass index (BMI) is 40 or higher.
  • Your BMI is 35 to 39.9, and you have a serious weight-related health problem. 
  • In some cases, you may qualify for certain types of weight-loss surgery if your BMI is 30 to 34 and you have serious weight-related health problems.


Bariatric surgery is done to reduce your risk of potentially life-threatening weight-related health problems, such as: Heart disease and stroke, nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH), Sleep apnea, Type 2 diabetes and high blood pressure.

Gastric bypass surgery can also improve your ability to perform routine daily activities, which could help improve your quality of life.

However, patients with binge eating disorder may continue this disordered eating behavior postoperatively, resulting in surgical failure initially or eventual weight regain. 

Also, active depression or other significant psychological disorders may result in similarly poor outcomes. 

While bariatric surgery can offer many benefits, all forms of weight-loss surgery are major procedures that may require you to get regular exercise or make permanent healthy changes to your diet. 


Given the benefits of the bariatric operations, what is preventing more morbidly obese individuals from undergoing bariatric surgery? 

As with any major procedure, bariatric surgery poses potential health risks, both in the short term and the long term, from adverse reactions to anesthesia, to infection, excessive bleeding or breathing problems. 

Depending on the type of surgery, they can also include longer term risks such as: Diarrhea and vomiting, Bowel obstruction, Dumping syndrome, Gallstones, Hernias, Hypoglycemia, Malnutrition, Ulcers and Acid reflux.

From a practical standpoint, given the vast number of individuals that are potential candidates for surgery, there are an insufficient number of surgeons with sufficient expertise in these procedures to perform the necessary operations. 

Pros Cons
Initial and sustained weight loss Initial failure to lose weight
Resolution of obesity-related comorbidities Potential complication: perioperative, surgical, gastrointestinal, nutritional and psychological
Improved mortality Initial costs
Reduction in obesity-related health risks Weight regain
Improved quality of life Permanency
Psychosocial benefit

For those obese patients with multiple medical comorbidities and a resultant poor quality of life and reduced life expectancy, the potential unfavorable consequences of bariatric surgery described above may be surpassed by the potential benefits.
