Am I a Candidate for Bariatric Surgery? Start by Checking your BMI

Bariatric surgery is a personal decision that only you can make. Generally, bariatric surgery is recommended for patients who have unsuccessfully tried diets, exercise and nutritional counseling — and who are committed to making lifestyle changes.

Certain health conditions, however, may qualify you as a bariatric surgery candidate:

  • Have a body mass index (BMI) of more than 40. Men and women who are more than 100 pounds overweight.

  • Have a BMI of 35-40 with an obesity-related condition such as diabetes, high blood pressure, high cholesterol, heart disease or sleep apnea.

  • Can’t achieve sustained weight loss with only diet and exercise.

  • Are committed to lifestyle changes in diet, exercise and behavior.

  • Are committed to lifelong follow-up medical care.

If you have unsuccessfully tried diets, exercise and nutritional counseling, or have certain health conditions, you may qualify for bariatric surgery*.

In the United States, surgeons use three types of operations most often:

  • laparoscopic adjustable gastric band
  • gastric sleeve surgery, also called sleeve gastrectomy
  • gastric bypass

Surgeons use a fourth operation, biliopancreatic diversion with duodenal switch, less often. Each surgery has its own benefits and risks. The patient and provider should work together to select the best option by considering the benefits and risks of each type of surgery. Other factors to consider include the patient’s BMI, eating habits, health conditions related to obesity, and previous stomach surgeries.

  • Roux-en-Y Gastric Bypass  RYGB restricts food intake. RYGB also decreases how food is absorbed. Food intake is limited by a small pouch that is similar in size to the pouch created with AGB. Also, sending food directly from the pouch into the small intestine affects how the digestive tract absorbs food. The food is absorbed differently because the stomach, duodenum, and upper intestine no longer have contact with food.
  • Vertical Sleeve Gastrectomy | Gastric Sleeve  In gastric sleeve surgery, also called vertical sleeve gastrectomy, a surgeon removes most of your stomach, leaving only a banana-shaped section that is closed with staples. Like gastric band surgery, this surgery reduces the amount of food that can fit in your stomach, making you feel full sooner. Taking out part of your stomach may also affect gut hormones or other factors such as gut bacteria that may affect appetite and metabolism. This type of surgery cannot be reversed because some of the stomach is permanently removed.
  • Laparoscopic Adjustable Gastric Band (AGB) In this type of surgery, the surgeon places a ring with an inner inflatable band around the top of your stomach to create a small pouch. This makes you feel full after eating a small amount of food. The band has a circular balloon inside that is filled with salt solution. The surgeon can adjust the size of the opening from the pouch to the rest of your stomach by injecting or removing the solution through a small device called a port placed under your skin. After surgery, you will need several follow-up visits to adjust the size of the band opening. If the band causes problems or is not helping you lose enough weight, the surgeon may remove it.

Bariatric procedures are considered major surgery, and you must consider the risks and long-term health benefits. Bariatric surgery may help you reduce or eliminate some diseases such as described in the table below.

Health Improvements After Gastric Bypass Surgery*

Health Problem (Comorbidity)

Result After Gastric Bypass Surgery

Type 2 Diabetes– Resolved in 83.7% of patients.
High Blood Pressure– Resolved in 67.5% of patients
High Cholesterol– Improved in 94.9% of patients
Obstructive Sleep Apnea– Resolved in 80.4% of patients
Acid Reflux/GERD– Resolved in 98% of patients
Depression– Improved in 47% of patients
Osteoarthritis and Joint Pain– Resolved in 41% of patients
Stress Urinary Incontinence– Resolved in 44% of patients


 In medical terminology, “resolved” is defined as removing all known symptoms and signs of the condition or disease.
 In medical terminology, “improved” is defined as reducing the known symptoms and signs of the condition or disease.

Some side effects may include bleeding, infection, leaks from the site where the intestines are sewn together, diarrhea, and blood clots in the legs that can move to the lungs and heart.

Examples of side effects that may occur later include nutrients being poorly absorbed, especially in patients who do not take their prescribed vitamins and minerals. In some cases, if patients do not address this problem promptly, diseases may occur along with permanent damage to the nervous system. These diseases include pellagra (caused by lack of vitamin B3—niacin), beri beri (caused by lack of vitamin B1—thiamine) and kwashiorkor (caused by lack of protein).

Other late problems include strictures (narrowing of the sites where the intestine is joined) and hernias (part of an organ bulging through a weak area of muscle).

Two kinds of hernias may occur after a patient has bariatric surgery. An incisional hernia is a weakness that sticks out from the abdominal wall’s connective tissue and may cause a blockage in the bowel. An internal hernia occurs when the small bowel is displaced into pockets in the lining of the abdomen. These pockets occur when the intestines are sewn together. Internal hernias are thought to be more dangerous than incisional ones and need prompt attention to avoid serious problems.

Some patients may also require emotional support to help them through the changes in body image and personal relationships that occur after the surgery.

What is obesity?

Obesity is defined as having a body mass index (BMI) of 30 or more. BMI is a measure of your weight in relation to your height. Class 1 obesity means a BMI of 30 to 35, Class 2 obesity is a BMI of 35 to 40, and Class 3 obesity is a BMI of 40 or more. Classes 2 and 3, also known as severe obesity, are often hard to treat with diet and exercise alone.

What is bariatric surgery?

Bariatric surgery is an operation that helps you lose weight by making changes to your digestive system. Some types of bariatric surgeries make your stomach smaller, allowing you to eat and drink less at one time and making you feel full sooner. Other bariatric surgeries also change your small intestine—the part of your body that absorbs calories and nutrients from foods and beverages.

Bariatric surgery may be an option if you have severe obesity and have not been able to lose weight or keep from gaining back any weight you lost using other methods such as lifestyle treatment or medications. Bariatric surgery also may be an option if you have serious health problems, such as type 2 diabetes or sleep apnea, related to obesity. Bariatric surgery can improve many of the medical conditions linked to obesity, especially type 2 diabetes.

The type of surgery that may be best to help a person lose weight depends on a number of factors. You should discuss with your doctor what kind of surgery might be best for you.

What is the difference between open and laparoscopic surgery?

In open bariatric surgery, surgeons make a single, large cut in the abdomen. More often, surgeons now use laparoscopic surgery, in which they make several small cuts and insert thin surgical tools through the cuts. Surgeons also insert a small scope attached to a camera that projects images onto a video monitor. Laparoscopic surgery has fewer risks than open surgery and may cause less pain and scarring than open surgery. Laparoscopic surgery also may lead to a faster recovery. Open surgery may be a better option for certain people. If you have a high level of obesity, have had stomach surgery before, or have other complex medical problems, you may need open surgery.
