Gastric Lap-Band Criteria
Do I qualify for weight loss surgery?

Gastric Lap-Band Criteria: Do I weigh "enough?"

Your BMI (Body Mass Index) is used to determine whether your weight makes you a good candidate for weight loss surgery.

Your Weight! lbs.

Your Height! ft. in.

Your Body Mass Index

BMI Interpretation: < 18.5 = Underweight
18.5 - 24.9 = Normal
25.0 - 29.9 = Overweight
30.0 - 34.9 = Obesity (Class I)
35.0 - 39.9 = Obesity (Class II)
40.0+ = Extreme Obesity (Class III) According to NIH Guidelines (National Institute of Health), you're a good candidate for gastric banding surgery if:

  • Your BMI is 40 or higher
  • Your BMI is 35-39.9 and you have have one or more weight related health conditions (called "comorbidities") such as diabetes, hypertension, sleep apnea, reflux, heart disease, stroke, respiratory problems, osteoarthritis, joint problems, etc.
  • You're at least 100 pounds over your estimated ideal weight

However, meeting the technical weight criteria for gastric lap-band surgery is not the same thing as being a good candidate for weight loss surgery.

Just because your weight puts you in a category eligible to qualify for bariatric surgery doesn't mean it's necessarily right for you. That's why most insurance companies require that you meet with a psychologist and/or a dietitian (like me!) before surgery as part of your pre-op evaluation. Gastric Lap-Band Criteria: Will a Dietitian Give Me the OK? When I interview a potential gastric band candidate, I'm assessing:

  • Have you made adequate diet attempts?
  • Have you exhausted all traditional dieting methods?
  • Have you truly given past dieting attempts your all?
  • How long have you been overweight?
  • Are you an emotional eater?
  • Have you made adequate attempts to exercise?
  • Have you made adequate attempts at behavior modification?
  • Do you have realistic expectations of weight loss surgery?
  • Are you committed to making lifelong changes in your diet and lifestyle?
  • Do you understand and are you willing to follow the diet after lap-band surgery including changing how much you eat, what you eat and how you eat?
  • Do you have a good support system?
Ultimately, I'm assessing if a client is "nutritionally appropriate" to proceed. Gastric Lap-Band Criteria: Will a Psychologist Give Me the OK? Weight loss surgery is life altering. You'll likely have to meet with a psychologist pre-op who will assess whether you're mentally and emotionally prepared to proceed with this life changing event.

Gastric lap-band surgery may be right for you if:

  • You're at least 18 years old
  • Your BMI is greater than 40
  • You're at least 100 pounds overweight
  • Your BMI is 35-39.9 and you have one or more obesity related health conditions
  • You've exhausted all other traditional methods of weight loss including diet, exercise, and behavior modification
  • You're committed to making changes in your diet and lifestyle


The ULTIMATE Gastric Lap-Band Criteria: YOUR DEGREE OF COMMITMENT Weight loss surgery does not guarantee weight loss success. Gastric banding is only a TOOL. A good candidate for bariatric surgery recognizes this fact and is willing, motivated, and committed to following the post-op diet and exercise guidelines. If you meet the weight criteria for gastric lap-band surgery and think you're a good candidate, your next step is to make an appointment with your doctor to discuss it in more detail!
