Gastric Band Surgery Requirements

Gastric Band Surgery Requirements - Bariatric Fusion

Gastric band surgery is a less invasive option when compared to other bariatric procedures. However, like any other bariatric surgery, you have to meet the qualifications.

In this article, we explain the requirements for a gastric lap band. We’ll also explain in detail what can prevent you from getting one.

What This Article Covers:

Weight and BMI Level

In order to be a candidate for any bariatric procedure, you must meet the basic qualifications.

A person would generally need a body mass index (BMI) of 40 or higher in order to be considered for gastric band surgery.

A BMI of 40 or more places someone in the category of morbidly or severely obese. This is a serious health condition resulting from abnormally high weight that increases the risk of life-threatening illness, requiring medical attention.

BMI can be calculated different ways. The typical BMI calculation is found by dividing weight in pounds by height in inches squared and then multiplying by 703.

For example, if a person weighs 240 pounds and their height is 5'5" (65 inches), their BMI would be 40. There are also valid BMI calculators available to you online to make things easier.

You may even be required to lose some weight to meet gastric banding requirements.

Health Conditions

You may also qualify for this surgery with a BMI of 35 to 40 and obesity-related health conditions, such as:

  • Heart disease
  • High blood pressure
  • Type 2 diabetes
  • Severe sleep apnea
  • Severe arthritis

There are some health conditions that can prevent you from having a gastric band. This may include:

  • Inflammatory diseases of the intestinal tract, including ulcers and Crohn's disease
  • Serious heart and lung problems
  • Long-term steroid treatment
  • Portal hypertension, which is high blood pressure in the main vein in your digestive system
  • Cirrhosis of the liver
  • Chronic pancreatitis
  • Autoimmune disorders such as lupus

An unresolved drug, alcohol, or cigarette addiction can also diminish your chances of having any bariatric surgery.

It’s good to find out what material the gastric band is made of in case you are allergic to it. This is usually medical-grade silicone, which shouldn’t be a problem for the vast majority of people.

A silicone allergy is extremely rare, but something to be aware of, just in case.


One of the gastric band surgery requirements is that you have to be at least 18 years old.

Every surgery center will have different policies in place. Some allow bariatric surgery in adolescents. As with any surgery, there are complications and risks that are involved.

Other age-related health conditions can be a factor in whether or not bariatric surgery is right for you. It is always recommended to have a discussion with your healthcare provider about your options.

Personal Factors

If you are pregnant, you will need to wait until after the birth for this surgery. If you think you might be pregnant, you must have a pregnancy test first. With any bariatric surgery, it is recommended to wait 12 to 24 months before conceiving after weight loss surgery.

Another factor is readiness for lifestyle change. You will see weight regain after any bariatric procedure if you do not adhere to lifestyle changes, including diet and exercise.

Band prolapse and slippage can be of concern with overeating and noncompliance to your new bariatric diet. This can cause abdominal pain, nausea, vomiting, and reflux. To help you avoid overeating, you can consider bariatric portion plates or bariatric meal replacements, like bariatric soup.

You will need to remember that carbonated beverages are not recommended for at least 3 months after surgery, if at all. Soda, sparkling water, and other carbonated beverages can upset the stomach. This will cause gas and nausea while healing.

If you are considering having a gastric band, you need to be willing to work with your doctor and dietitian regularly. You will need to have consistent follow ups to have the band re-adjusted.

You must get medical help if you have problems like pain and discomfort in your abdomen.

Tobacco smokers will be asked to stop smoking for at least 6 weeks before the surgery.
