  • Dividing your weight measurement by your height
  • Dividing this result by your height again

For example, if you weigh 120kg  are and 1.7 metres tall then your BMI would be calculated as:

  • 120 divided by 1.7 = 70.59
  • Then divide this by your height again, 70.59 divided by 1.7 = 41.5
  • Your BMI would be 41.5 (which would put you in the obese range)

  • Have a BMI of over 40

Having the surgery could also help to relive the symptoms of any health problems that are linked to your weight. Gastric sleeve surgery has proven to be particularly helpful at tackling type 2 diabetes, so it can be a good option if you are affected by this condition and comparing options for weight loss surgery. Many people notice a rapid improvement in their diabetes symptoms and it can disappear completely in some cases.

Previous Attempts at Weight Loss

  • Ensure that you are as healthy as possible before undergoing the procedure if you do still need to have a sleeve gastrectomy
  • Prepare you for the long term changes that you’ll need to make after the surgery in order to successfully lose weight
  • Show your doctor that you are committed and willing to work hard to make your surgery a success

Your General Health

Your Attitude

The doctor won’t just ask about your physical health when considering whether you’re a good candidate for weight loss surgery. It’s important to ensure that you are mentally prepared for the experience too. You will need to have realistic expectations of what the procedure can do for you.

It is also important to be aware of both the positive and negative effects that it could have on your wellbeing and relationships. For example, while losing weight can help you to feel happier and more confident, it can also be stressful. The dramatic changes you’ll be making to your life can also affect your relationships with other people.
