FAQs About Bariatric Surgery and Medical Weight Loss
If you’re considering bariatric weight-loss surgery, you probably have a lot of questions. You may also read more in-depth information about our treatments and an overview on what to expect when you choose bariatric surgery or medical weight loss.
We perform bariatric surgery on patients between the ages of 18-65. If you're younger than 18, we will work with our pediatric colleagues to ensure your success. We evaluate patients over age 65 on a case-by-case basis. Please keep in mind your insurance may restrict your options.
We look at Body Mass Index (BMI), which is the weight over the body surface area squared. Patients who have a BMI of 35-40 and have obesity-related conditions are candidates for this surgery. Patients with a BMI greater than 40 who don't have other weight-related conditions are also candidates.
All types of weight-loss surgery effectively treat obesity-related conditions like sleep apnea and diabetes. In terms of weight loss, here’s how the surgeries compare:
- Gastric bypass allows you to lose 75 percent of your excess body weight.
- Sleeve gastrectomy can help you achieve about 60 percent weight loss within one year.
- Adjustable gastric banding (lap-band) enables you to shed 50 percent of your excess body weight over about a two-year time span.
Your personal success relies on your own commitment to making the necessary lifestyle changes to stay healthy after bariatric surgery. We will help you stay on track before, during, and after surgery.
Call us at 650-736-5800 for a consultation. We’ll give you all the information you need to make an informed decision about bariatric surgery.
Your weight loss program will be tailored to your unique needs. It may or may not include a liquid diet. On your first visit to the BMI Clinic, your team of experts will begin to design a program just for you.
Perhaps more than weight loss, we offer you hope. In your past efforts to lose weight, you probably did not have a supportive team of experts at your side like you will with our program. You did not have counselors helping you figure out why you overeat – and how to modify that behavior. Perhaps your weight gain has been caused by an undiagnosed medical condition that we can discover and address. Our medical weight loss program is supervised by a physician and includes a dedicated team of experts from dieticians to sleep therapists. We will be here to support you even after your formal weight loss program ends.
Even a modest reduction in your overall body weight can have a positive effect on obesity-related conditions like diabetes, hypertension and joint pain. If you lose a lot of weight, you may find you don’t need to take certain medications anymore. Or your dosage may be reduced.
Yes, it can. It’s never too late to begin a medical weight loss program. The sooner you begin, the sooner you will get those excess pounds off. Medical weight loss works more slowly than bariatric surgery. You didn’t become overweight in a day, and you won’t lose 100 pounds in a day, either. We will help you accomplish slow, steady, healthy weight loss through a combination of medical and lifestyle interventions. Through our comprehensive weight loss expertise, we can offer proven surgical solutions for patients who only achieve partial response to medical weight loss.
Call us at 650-736-5800 for a consultation. We’ll be happy to discuss whether or not our medical weight loss program can help you achieve your goals.
