Your bariatric team will explain why one of these procedures may be better for you than another, and work with you after your surgery to help you achieve these goals.

The extensive evaluation you undergo takes these and other factors into consideration.

Your Weight Loss Goals
The percent of excess weight you are expected to lose and the rate at which you lose weight differs for each surgery.

Your Medical History
Your history with medical problems such as acid reflux and diabetes -- and how long you’ve had them -- can make one surgery better for you than another.

Your Risk Factors
Each weight loss procedure is associated with a different set of risks, which may vary based on your specific medical condition. For example, some people may be at higher risk for ulcers after certain bariatric surgeries if they take NSAID medications (like ibuprofen).

Previous Scar Tissue
Previous abdominal incisions may make some weight loss surgeries more difficult. However, we can still typically perform weight loss surgery safely and through small incisions (minimally invasive).

Compliance with Long-Term Follow-Up
People who don’t adhere to lifelong nutritional regimens may want to avoid weight loss surgeries that require this stringent adherence. Also, people who have difficulty attending follow-up appointments are not as successful at maintaining consistent, healthy behaviors and may be at risk for weight gain and complications.

Smoking Habit
Smoking increases your risk for blood clots, pneumonia, and other lung problems after surgery. Unfortunately, it is not safe to have weight loss surgery if you smoke or use other nicotine or tobacco products. The risks of having problems after bariatric surgery (including leaks and ulcers) are much higher. For this reason, we require that you permanently quit smoking before having surgery. We will test your urine before surgery to make sure the harmful nicotine is out of your system.

Timing of Surgery 
Given that bariatric surgery will involve significant adjustment, recovery, and behavioral changes, our team will assist you in determining the best time for you to undergo surgery. Many factors are considered when deciding the optimal timing of surgery, including the status of your medical conditions; stability and support for life stressors, mood, or other psychological symptoms; and your preparation for surgery.
