Sleeve Gastrectomy or Gastric Bypass Surgery?

Both operations are great effective operations performed in the hands of an experienced surgeon.  In making a determination on what is a suitable operation for an individual multiple factors need to be considered.  Nutritional factors such as underlying vitamin deficiencies, your eating habits and hunger level;  your emotional eating behavior, your food addiction susceptibility.  These factors along with additional personal factors such as your aversion to risk and your overall health state to with stand risk of surgery are important in making a decision on which surgery is right for you.  Secondary factor that are related to your physiology and comorbidities, such as diabetes also needs to be considered.  Overall, Gastric bypass is more effective for patients with diabetes.  Additional factors that needs to be considered is your previous operative and history and your anatomy.  If you have a hernia, depending on the size of your hernia your doctor will make a determination on whether a gastric bypass or a laparoscopic sleeve gastrectomy is a more suitable operation.  Yes gastric sleeve surgery is often an easier and safer procedure to perform and the overall risk is lower than the gastric bypass.  However, the gastric bypass has better published and follow up data for its effective weight loss.  In addition, there are better revision options for the sleeve gastrectomy if the patient is unsuccessful.  Having said that I have patients in both category that do as well and are equally successful, which bring home the underlying theme that surgery is just a tool and how you use it is the most important predictor of your outcome.  The typical information session for a bariatric patient can take from 1-2 hours of lecture and questioning by the audience to provide initial information on how to think about bariatric surgery.  We then answer general questions from the audience and allow the audience to reflect on their concerns.  Once you have made a determination that surgery is right for you - we will schedule you for a consultation with the physician and the nutritionist.  During the consultation we make sure we have conveyed the information to you and you have understood the information.  Once you have a clear understanding of the procedure you can make an educated decision on what is appropriate.  You are changing your body make sure you understand the issues involved, find a doctor that can take time to explain and listen to you. 

There are different elements that are taking in to account to choose a procedure:- Weight and height (BMI)- Body composition ( body fat percentage)- Medical conditions associated ( Diabetes, high blood pressure, obstructive sleep apnea, etc.)- Patient lifestyleIf you are interested in this possibility, you need to arrange a consultation with a certified bariatric surgeon. He will be able to advise you which could be the right treatment option for your specific situation. But the gastric sleeve is a less invasive procedure than bypass, also very safe and has become the most popular procedure performed world wide. New scientific data has shown comparable results with bypass, to be as effective in weight loss and in remission or control of chronic illness. With a gastric sleeve you can carrie on with a more normal life style with out drastic changes.

Hello,
Thank you for your question.
If your main intention is just to lose weight, I would recommend sleeve gastrectomy; however, if you have metabolism-related side-diseases such as diabetes, hyper-tension or hypercholesterolemia; you may choose a gastric bypass.
I hope this answer helps you
