Obesity: A Closer Look

Obesity is a common condition in the developed world. In the UK, it’s estimated that about 1 in 4 adults are considered obese. Obesity is classed as having a Body Mass Index (BMI) of over 30.


What is obesity?

Obesity is generally considered a chronic condition caused by consuming more calories than your body uses. In other words, your ‘input’ is higher than your ‘output’.

It is caused by a complex mix of genetic, metabolic, behavioural and environmental factors.

How to check if you’re obese

Understanding how to check your BMI is key to knowing if you’re a healthy weight. It’s a combined measurement of your weight  and height. However, it’s important to keep in mind that it is only a guide, as it doesn’t take into account muscle mass. 

To work out your BMI, weight is measured in kilograms and height in metres in order to obtain the correct results.

BMI calculator: weight ÷ (height x height) = BMI

e.g. 100kg ÷ (1.6 x 1.6) = BMI of 39

You can use our handy checker to work out your BMI and understand whether you may be a healthy weight, overweight or obese.

For the majority of adults:

18.5 to 24.9 = a healthy weight

25 to 29.9 = overweight

30 to 39.9 = obese

40 or above = severely obese

What causes obesity?

In the last two decades, the rate of obesity has more than doubled in men and women. This is believed to be due to a range of factors, some of which are the abundance of high calorie food and a higher instance of people leading sedentary lifestyles. Many factors play a part in this increased calorie input, such as consuming larger portions, having a higher sugary drink intake, comfort eating, having a higher alcohol intake, and a having higher intake of processed foods.

Environmental, hormonal and social factors can also play a part in developing obesity, which can make weight loss more complex and harder to achieve. For example, large portions and frequent consumption of foods high in processed/saturated fats can be second nature to many people. Social occasions can revolve around food and/or alcohol too, so it can be incredibly difficult to lose weight.  Therefore, obesity is often linked to various different factors.

One of the most common obstacles to losing weight is weight cycling or what is called the ‘yo-yo’ effect. Simply defined, often weight loss is achievable, but maintaining that weight loss is very difficult. When the ‘diet’ ends, the weight is often put on again - and more!


Weight loss options


Weight loss surgery

Weight loss surgery can be a good option for people suffering with obesity. If you’ve tried exercising and dieting but still have a BMI over 35, weight loss surgery could mean that you can lose that excess weight, maintain it, and become healthier as a result.

We provide three types of weight loss surgery.

Gastric Band

Gastric band surgery is designed to help you lose weight gradually. During surgery, a silicone ring is placed close to the top of the stomach. It stimulates the nerve endings on the stomach wall and helps manage portion sizes and hunger. Through a process of band adjustments, the band can be tightened as needed, until small portions keep you satisfied for around 4-5 hours after eating

Gastric Sleeve

Gastric sleeve surgery involves removing part of the stomach to reduce its overall capacity - this will enable you to feel satisfied on smaller portions. The portion of the stomach that is removed is also responsible for producing the ‘hunger hormone,’ grehlin, so this surgery can help manage hunger levels as well as a reduction in food intake.

Gastric Bypass

As well as surgically reducing the size of the stomach, gastric bypass surgery bypasses part of the small intestine. Food travels through the smaller stomach pouch directly into the second part of the small intestine. This means that bypass surgery works by reducing the amount of food eaten due to the smaller stomach, and helps to manage hunger due to the reduction in gut hormones.

If you have a BMI between 33-34.4 and have health concerns caused by obesity, you might also qualify for weight loss surgery. Get in touch with us today to find out more. 


Non-surgical weight loss options


If your BMI is 30-34, it’s likely that you won’t be suitable for weight loss surgery. However, we offer non-surgical weight loss techniques that can help you to reach your goal weight.

Self-administered weight loss programme

This can help you lose weight through suppressing your appetite and helping you to feel fuller more quickly. In turn, it can help to address health concerns such as high blood pressure and high cholesterol.

This treatment might also be suitable if you have a BMI of at least 27 and suffer from a weight-related health condition such as type-2 diabetes.

While you’ll administer this weight loss treatment at home, we’ll be there to support you each step of the way.


People with a BMI of under 30 who are satisfied with their weight but would like to remove small areas of stubborn fat deposits might find that liposuction is the right treatment for them.

We offer both liposuction and vaser liposuction. Traditional liposuction involves the suction of fatty tissues and excess fluid through a cannula. Vaser liposuction is similar, but it uses ‘vibration amplification of sound energy on resonance’ to break down the stubborn, unwanted fat before draining.
