BMI Calculator

Body Mass Index (BMI) is very simply the calculation of an individual’s weight in relation to their height. It is used to give people an indication of how much body fat they have and therefore highlights how healthy they are.

BMI figures are then categorised into various divisions outlined by the World Health Organisation as shown below. We will give advice to candidates with a high BMI, and advise on which obesity surgery procedure best suits their weight loss needs.

Calculate your BMI today using our Body Mass Index Calculator, and see what category you fall under.

 

BMI less than 19 (Underweight)

A BMI of less than 19 shows you to be underweight.

Am I suitable for weight-loss surgery?

Most definitely not, you do not need any form of weight-loss surgery.

BMI of 19 to 25 (Ideal weight)

Congratulations! Your weight is within the normal range. At this stage, it would appear that you are not a candidate for obesity treatment.

Am I suitable for weight-loss surgery?

No, as you are currently at your ideal weight.

BMI of 25 to 30 (Overweight)

This BMI is classed as mildly obese. At this weight there is a low risk to your health, but it is important to keep this under scrutiny. A little weight loss through diet, exercise and other lifestyle changes may help to lower your BMI.

Am I suitable for weight-loss surgery?

At this stage you may want to consider a non-surgical weight-loss management programme, the Gastric Balloon, which is inserted orally and is removed after six months. The balloon is designed to regulate the body’s dietary routine, by decreasing the size of the stomach so the body gets accustomed to that pattern of eating.

BMI over 30 (Obese)

A BMI of over 30 is classed as moderately obese with an increased risk of developing heart disease, type 2 diabetes, high blood pressure, high cholesterol, arthritis, asthma, sleep apnoea and several cancers. With this result it would appear that you may be a candidate for obesity surgery.

Am I suitable for weight-loss surgery?

Yes. The most appropriate form of weight-loss surgery for you would be the gastric band. The band is a reversible procedure and is inserted around the top of stomach, in order to shrink the size of your stomach resulting in the patient feeling full, far more quickly.

BMI over 35 (Severe Obesity)

With this BMI you would be classed as severely obese with a significant increased risk of developing heart disease, type 2 diabetes, high blood pressure, high cholesterol, arthritis, asthma, sleep apnoea and several cancers.

Am I suitable for weight-loss surgery?

Yes. The most appropriate form of weight-loss surgery for you would be the gastric band. The band is a reversible procedure and is inserted around the top of stomach, in order to shrink the size of your stomach resulting in the patient feeling full, far more quickly.

BMI over 40 (Morbid Obesity)

This BMI score is classed as morbidly obese. There is a very high risk of developing heart disease, type 2 diabetes, high blood pressure, high cholesterol, arthritis, asthma, sleep apnoea and several cancers. You are almost certainly a candidate for obesity surgery.

Am I suitable for weight-loss surgery?

Yes. The most appropriate form of weight-loss surgery for you would be either the gastric band or gastric bypass. Both options would be discussed at length with an obesity surgeon at the point of consultation and would be dependent upon the individual patient’s comorbidities.

BMI over 50 (Super Obesity)

This weight is classed as super obese. This is a potentially life threatening state, with an extremely increased risk of developing heart disease, type 2 diabetes, high blood pressure, high cholesterol, arthritis, asthma, sleep apnoea and several cancers. You are almost certainly a candidate for obesity surgery.

Am I suitable for weight-loss surgery?

Yes. The most appropriate form of weight-loss surgery for you would be either the gastric band or gastric bypass. Both options would be discussed at length with an obesity surgeon at the point of consultation and would be dependent upon the individual patient’s comorbidities.
