Bariatric Surgery Compared

Sleeve Gastrectomy Surgery

Picking the right surgical weight loss option is a big decision to help patients reach a healthy weight when they aren’t seeing results with diet and exercise alone. Each procedure has its benefits and risks, as with any surgery, so it’s important to know the difference between the three before choosing which is right for you. Your bariatric surgeon will support you in making the best decision based on your unique needs.

Sleeve Gastrectomy Pros and Cons

During a laparoscopic sleeve gastrectomy, also known as “sleeve” surgery, doctors surgically make the stomach smaller by using surgical staplers to remove about 80% of it. What’s left of the stomach is about the same size and shape as a banana.

Benefits

  • Effective weight loss and improvement of obesity-related conditions
  • Simple and shorter surgery time
  • Appropriate for certain patients with high-risk medical conditions
  • Can be the first step in weight loss for patients with severe obesity and used as a bridge to another surgery for additional weight loss
  • Less risk of ulcer or stricture

Risks

  • Procedure is non-reversible
  • May worsen or cause new onset reflux or heart burn

Gastric Bypass Surgery

Picking the right surgical weight loss option is a big decision to help patients reach a healthy weight when they aren’t seeing results with diet and exercise alone. Each procedure has its benefits and risks, as with any surgery, so it’s important to know the difference between the three before choosing which is right for you. Your bariatric surgeon will support you in making the best decision based on your unique needs.

Gastric Bypass Pros and Cons

Gastric bypass surgery involves dividing the stomach into two parts and bypassing a portion of the small intestine, reducing the amount of food your body can absorb. Gastric bypass is generally considered a more invasive weight loss surgery than gastric sleeve.

Benefits

  • Reliable and long-lasting weight loss
  • Effective for resolving obesity-associated conditions
  • Highly refined and standardized technique

Risks

  • More complex than sleeve gastrectomy or gastric band
  • Results in more vitamin and mineral deficiencies than sleeve gastrectomy or gastric banding
  • Risk for small bowel complications, obstructions or internal hernia
  • Risk of developing ulcers, especially if using NSAIDs or tobacco
  • Increased risk of forming kidney stones
  • Risk for “dumping syndrome,” which involves feeling sick after eating or drinking, especially foods that are sweet

Gastric Band Surgery

Picking the right surgical weight loss option is a big decision to help patients reach a healthy weight when they aren’t seeing results with diet and exercise alone. Each procedure has its benefits and risks, as with any surgery, so it’s important to know the difference between the three before choosing which is right for you. Your bariatric surgeon will support you in making the best decision based on your unique needs.

Gastric Band Surgery Pros and Cons

gastric band surgery illustration

During gastric band surgery, a band is placed around the upper part of the stomach to restrict its size. This helps you feel fuller soon and eat less. It has the lowest risk of complications compared to gastric sleeve and gastric bypass surgery.

Benefits

  • No division of the stomach or intestines
  • Patients can go home the same day
  • The band can be removed
  • Lowest risk for vitamin and mineral deficiencies

Risks

  • The band may need several adjustments and monthly office visits during the first year
  • Slower and less weight loss than other surgical procedures
  • Risk of band slipping or damaging the stomach over time (band erosion)
  • Requires a foreign device to remain in the body
  • Highest rate of re-operation
  • Can result in swallowing problems and enlargement of the esophagus

Bariatric Surgery Requirements and Qualifications

To be considered as a candidate for surgery, most insurance providers require certain criteria are met.

  • BMI greater than 40
  • BMI of 35 to 39.9 with one or more obesity-related diseases or problems, also known as co-morbid conditions
  • Documented efforts at weight-loss through a medically safe, well-balanced diet
  • Absence of other medical conditions that would make surgery unsafe
  • A willingness to lose weight and make changes in your eating habits and physical activity
  • Must be willing to stop frequent eating and drinking of high-calorie foods and beverages
  • You must be evaluated by a psychologist trained in bariatric psychology
  • You must be willing to increase physical activity and exercise as weight loss occurs
  • A commitment to yourself and your surgeon to keep regularly scheduled appointments

Bariatric Surgery Follow-up Care

We believe the care you need after bariatric surgery is most successful with a comprehensive team approach. This means you’ll have a follow-up care schedule over the course of several weeks to months after your procedure, which could include:

  • Dietary and mental health counseling
  • Exercise consultation
  • Reconstructive surgery

Bariatric Surgery Insurance Coverage

Pre-Insurance Approval

Many insurance plans cover weight loss surgery if you meet the National Institute of Health guidelines. It’s your responsibility to contact your insurance company to be sure they’ll pay for the surgery. Here are some questions to ask:

  • Is the surgeon in my insurance network?
  • Is bariatric surgery covered under my policy?
  • Are there special requirements, such as a physician-supervised diet and/or exercise program, that must be done before the surgery can be approved?

The UnityPoint Health team will request approval from your insurance company and send copies of all your medical records. If you receive a denial from your insurance company due to a special requirement, please contact your primary care physician to help you meet that requirement.

Qualifying for Bariatric Surgery with Your Insurance Company

Before your consultation, call the customer service number on your insurance card to make sure your plan covers weight loss surgery. Tell the customer service representative you’re interested in bariatric surgery and ask if the service is covered by your plan. You may have to use phrases like, “morbid obesity surgery,” “weight loss surgery” or "bariatric surgery." If the service isn’t covered or is excluded, this means your employer, or whoever you get your insurance through, didn’t pay for this benefit. You may contact our office regarding cash payment options. Ask questions, including:

  • What’s my co-insurance and deductible for bariatric surgery?
  • Is there an out-of-pocket maximum for this procedure? Is there a lifetime maximum for weight loss surgery?
  • If they say yes, or tell you it must be deemed "medically necessary,” ask the following questions:
    • What are your BMI requirements?
    • Do I need certain co-morbid conditions (medical conditions related to your weight)? If so, what are they?
    • Do you have a list of approved mental health providers?
    • Do I have to complete a physician-supervised diet and for how long?
    • Does the program need an exercise component?
    • Do I have to see a dietitian?
    • Do I need to complete a sleep study?
    • Do I need to obtain any cardiac testing?
    • Do I need any pulmonary testing (pulmonary function tests)?
    • Do I need to have certain blood work drawn?
    • Are there any other requirements?
    • Can you provide me with a checklist (the requirements for surgery)?

Physician-Supervised Diet - Information for Patients

Please be advised that every insurance plan is different. We strongly encourage patients to contact their insurance companies to see what's required for their pre-approval. Here are some general guidelines regarding a physician-supervised diet.

  • What is a physician-supervised diet? A physician-supervised diet, in its most basic form, is when a patient meets with their family physician every month to discuss their weight loss goals, an exercise plan, nutritional changes and have their current weight and height documented. It’s important your physician thoroughly documents everything discussed at these visits in your chart. Some insurance companies require patients to be on these diets for a period before surgery; others require patients to meet with a dietitian or nutritionist, too. If this is a requirement of your insurance plan, we can’t submit your pre-approval until this diet is completed. 
  • I think I already completed a physician-supervised diet. How can I be sure? Contact your physician and ask if this diet was documented in your medical records. If it was, and within the past three years, have those records sent to our office. Don't forget to contact your insurance company, because their requirements may be different than what you already completed.
  • Is a letter from my physician good enough?  It depends. Check with your insurance company to see what they require for insurance approval. Most insurance companies require more than just a letter. Insurance companies want to see that the patient and doctor met routinely in the office. Most also want to track fluctuations in weight from each visit. It’s nice, however, to have a letter of support from your family physician to send with your pre-approval.

Post-Insurance Approval

Support: Depending on your location, different support options are available, such as bariatric support groups, even for those who didn’t have bariatric surgery at UnityPoint Health. We strongly recommend this support group to all patients as a great deal of information is exchanged by interacting with the other patients in the support group. Morbid obesity impacts many people, and you’ll find it easier to go through this life-changing surgery after talking with others who’ve experienced it.

Pre-Surgical Visit: After receiving approval from your insurance company, you’ll meet with our team for a final pre-surgery visit, where you can expect the following:

  • Schedule your bariatric surgery, and ask the surgeon questions.
  • Meet with our dietitian to discuss your eating habits and health history. The dietitian will also provide you with information on the importance of changing your diet before and after surgery.
  • Be tested for H. Pylori, a stomach ulcer-causing bacteria. You’ll be treated with antibiotics prior to surgery if you have it.

Bariatric Surgery: The procedure takes one to three hours. Provided you have no complications, you can expect to stay in the hospital overnight for the gastric sleeve and the Lap-Band procedure. If you have a bypass you can expect to stay up to three days. Immediate care during and after weight loss surgery is provided by these specialists:

  • Surgeon: Weight loss surgeons have extensive experience with critical care patients and provide comprehensive and complete care for any medical and surgical needs.
  • Physician's assistant: Our physician's assistant helps with all surgical cases and your care while you’re in the hospital.
  • Anesthesiologists: Board-certified anesthesiologists have extensive experience in the management of obese and overweight patients.
  • Pulmonary specialists: Experts in sleep medicine work in conjunction with the surgeon and hospital staff to ensure patients with underlying respiratory problems, such as breathing disorders found in morbidly obese patients, have the best chance at optimal recovery.
  • Cardiologists: Board-certified cardiologists are available for any cardiac difficulties.

Surgical Follow-Up Visits:  After surgery, you’ll have scheduled visits with the surgeon and other members of the weight loss surgery team. During these visits, weight loss, diet and physical activity are reviewed. Examinations and tests are performed as needed. Our goal is to provide continued care and encouragement. Follow-up is extremely important to every bariatric surgery patient. Although some of the tools for weight reduction are provided, learning to use these tools properly takes time. Patients must make attitude and habit changes related to eating, coping with stress and pleasure-seeking to ensure hunger is controlled and overeating or frequent snacking doesn’t occur.

FAQs

What are the risks of surgery?
Morbidly obese patients are at a higher risk when having any surgery due to their excess weight. Often, the patient may feel normal prior to surgery but have underlying medical problems they didn’t recognize. Long-term poor nutrition that has led to morbid obesity often causes poor heart and lung health.

Long-term complications include hair loss, dumping syndrome, diarrhea, vomiting, ulcers, bile gastritis, hernias, foreign body reaction, infection and virtually any other post-operative problem. Fortunately, these reactions aren’t common.

Some patients develop severe difficulties in coping with their weight loss. These difficulties may include depression, separation from spouse, divorce and even suicide gestures or actual suicide. Generally, someone who is well-adjusted and has a strong support system has a better recovery outlook. On the other hand, a person with mental health difficulties pre-operatively may continue to have them post-operatively, and they may even worsen.

Our team is committed to making your surgery as safe as possible. Advancements in the care of surgical weight loss patients over the past 20 years have allowed us to perform these surgeries with very low complication rates. Your personal risks are individually evaluated at your consultation with your surgeon. Remember, the risks of staying morbidly obese far outweigh the risks of surgery.
When will I start to lose weight?
You’ll start losing weight immediately after surgery. You may not notice any loss until the second week. The weight loss after each surgery occurs at a different rate. Each patient has a different weight loss rate dependent upon their adherence to the program and level of physical activity. A minimum rate of 1 to 2 pounds per week is minimally expected.
What happens to the rest of my stomach after weight loss surgery?
In the Roux-en-Y gastric bypass, the rest of the stomach is sectioned off from the new pouch but left intact. It still has a blood supply and drains any small amount of fluid through the small intestine, or duodenum. Because it’s not used, it shrinks in size and stays dormant.

In the sleeve gastrectomy, approximately 75% of the stomach is permanently removed leaving a smaller banana shaped stomach that holds approximately ½ cup of food per meal.
When can I return to work and exercise?
You’ll have a 10-to-20-pound weight restriction for two weeks following surgery. We encourage you to exercise as soon as you feel ready. This can be as early as one week. Some people return to work on the fourth day after surgery. However, most patients find they need one or two weeks before going back to work. You may feel tired during the first week, but you’ll feel more energetic as you lose weight.
Can I get too thin?
It’s unusual for a person to become too thin after weight loss. These procedures allow you to ingest and absorb a sufficient amount of nourishment, so you don’t get too thin.
Can I regain weight?
With any weight loss surgery, weight loss typically continues for two years and then plateaus. It’s important you follow the instructions given to you by the dietitian on how and what to eat. Failure to follow the recommended diet and exercise program will result in weight gain with any weight loss surgery.
What will happen to the excess skin after I lose weight?
After much weight loss, you may find yourself with excess skin. Some people find the excess skin a nuisance or unappealing. Weight loss after surgery continues for about 18 to 24 months. After that, your body is ready for additional surgery for excess skin removal. This is typically performed by a plastic surgeon, who will evaluate you and decide with you what areas may need work. This cosmetic surgery may not be covered by insurance. Documentation of health problems related to the excess skin may be required. These may include rashes, back pain or difficulty maintaining reasonable hygiene.

What do I do if I want to get pregnant?
We suggest waiting at least 18 months after surgery to have a child. Even after that, you must make sure your obstetrician is aware of your weight loss surgery and that you and your baby are followed closely.
What if I do not qualify for surgery or decide it is not right for me?
We have several non-surgical weight loss options available. Please refer to our Non-Surgical Options page.
