If you’re living with obesity and have been exploring weight loss treatment options, you may be wondering whether you qualify for gastric sleeve surgery and how much excess weight is “enough” to be considered for the surgery. At Phoenix Health, we understand how confusing the process can feel. This guide will help clarify the weight and health requirements for sleeve gastrectomy in the UK, including who might benefit most and when this procedure is usually recommended.
Understanding the Gastric Sleeve
Gastric sleeve surgery, also known as sleeve gastrectomy, is a common form of bariatric surgery where approximately 80% of the stomach is removed. The result is a slimmer, tube-shaped stomach that helps reduce appetite and food intake. It’s may be a safe and effective option for many patients, leading to significant weight loss and improvements in obesity related health conditions such as type 2 diabetes, high blood pressure, and sleep apnoea.
Who Is the Gastric Sleeve Recommended For?
The decision to proceed with weight loss surgery in the UK is based on more than just a number on the scale. While Body Mass Index (BMI) is an important factor, it’s not the only criteria considered for gastric sleeve surgery. The final decision is made by looking at your overall health, medical history, and lifestyle to ensure it’s the safest and most effective option for you.
At Phoenix Health, your surgeon may recommend a gastric sleeve if your BMI is 35 or above, or if your BMI is over 30 and you’re living with obesity related health conditions such as diabetes, high blood pressure, or obstructive sleep apnoea. These conditions often show significant improvement following weight loss surgery, as consistently demonstrated in clinical studies.
For those of Asian or Afro-Caribbean heritage, the BMI threshold may be lower, as the risks of metabolic complications often begin at BMI levels as low as 27. This is carefully considered during your assessment to ensure the safest and most effective approach for your background and risk profile.
Gastric Sleeve for Patients with Higher BMI
In some cases, patients with a very high BMI may be advised to have a gastric sleeve as the first stage of a two- part surgical plan. This is because a staged approach can make surgery safer by helping you lose enough weight to reduce surgical risk. About a year after the initial sleeve, a follow-up procedure such as a gastric bypass or SADIS may be carried out for further weight loss and health improvement.
When Sleeve Gastrectomy May Be the Safer Option
Your surgeon will also consider factors such as your age and whether you have heart, lung or liver conditions. For patients who are older or have medical concerns that make longer procedures riskier, the gastric sleeve may be a safer alternative to more complex surgeries. It’s shorter in duration and generally involves fewer surgical steps, while still delivering excellent results for many individuals.
Sometimes Surgery Plans Change: Here’s Why
Although uncommon, there are situations where a decision to switch from a gastric bypass to a sleeve gastrectomy is made during surgery itself. This can happen if, for example, your liver is larger than expected or there are dense adhesions from previous operations, making a bypass unsafe or technically difficult. If your surgical team anticipates that this might be a possibility in your case, you’ll be fully informed and asked to consent in advance, so you’re comfortable with the plan and any potential adjustments.
