Weight loss surgery

Why 'weight'?

Weight loss surgery (also known as 'bariatric surgery') is considered a safe and effective treatment to the obesity epidemic facing the UK. We take a look at the impact of obesity and why it is important not to ‘weight’.

Currently three out of 10 adults are obese, with this figure set to rise to around four in 10 by 2035. At that point, 76% of men and 69% of women will be overweight – a total of 40 million adults in the UK.

The Body Mass Index

Body Mass Index (BMI) describes a person’s body weight in relation to their height, and correlates strongly with the body fat content. It is the primary indicator used by bariatric surgeons to assess a patient’s suitability for surgery and to monitor post-operative weight loss.


There is a strong correlation between having a high BMI and a shorter life expectancy. Moderate obesity (30-39.9 BMI) cuts life by two to four years, whilst severe obesity (40-45 BMI) can cut life expectancy by an entire decade.


Obese individuals are 80 times more likely to develop type 2 diabetes than people of lower weight, and are more likely to suffer from conditions such as high blood pressure, heart disease, cancer and arthritis due to their increased BMI. 


Treating Obesity


The advice for the treatment of obesity is to eat a healthy, reduced-calorie diet and exercise regularly. However this can be hard to achieve.


If you are obese and have already tried to improve your diet and exercise levels with no success, the good news is that there are other options that could help you lose weight. It might be that you are an ideal candidate for weight loss (bariatric) surgery.


As a general guide weight loss surgery reduces the amount of food a person can eat. There are several weight loss surgery procedures, however the main three are gastric band, gastric bypass and gastric sleeve. Click here to learn more about what is involved. 

Weight loss surgery is recommended for people with a BMI of 40 or more, or those with a BMI of 35-40 who have a serious health condition that could improve with weight loss, such as type 2 diabetes. Whilst it has a very high success rate and can show impressive results, it requires commitment to diet regimes post-operatively from the patient. President of the British Obesity and Metabolic Surgery Society (BOMSS) and co-founder of Streamline Surgical, Shaw Somers says: “It isn’t a quick fix. Surgery is just a tool to help people to understand their relationship with food and that obesity is the result of this not working.” 

Post-surgery, the majority of patients experience an increase in their quality of life. As weight is lost, they become more capable of physical activity, experience better health and are at a reduced risk of developing obesity related diseases.
