At Tonic Weight Loss Surgery, we ensure that every patient is assessed thoroughly to determine the most appropriate treatment option. Here is what you need to know about qualifying for weight loss surgery in the UK.

Eligibility Criteria for Weight Loss Surgery

To be eligible for weight loss surgery in UK, you must meet one or more of the following criteria:

1. Body Mass Index (BMI)

Your BMI is a key factor in determining eligibility for bariatric surgery. You may qualify if:
You have a BMI of 40 or higher, or
You have a BMI of 35–40 and suffer from obesity-related health conditions such as:
Type 2 diabetes
High blood pressure (hypertension)
Sleep apnoea
Mobility issues caused by excess weight

2. A Long-Term Solution for Your Health

Weight loss surgery is designed for those who are ready for a permanent lifestyle change. Unlike short-term dieting or temporary fixes, bariatric surgery provides a sustainable approach to weight loss, empowering patients to take control of their health with the right medical and professional support. If you are looking for a long-term solution that works, surgery may be the right choice for you.

3. General Health and Fitness

To qualify for private surgery at Tonic Weight Loss Surgery, you should be in good general health and not have any medical conditions that could make the procedure too risky. You will undergo comprehensive medical assessments to ensure you are fit for surgery and able to recover successfully.

4. Commitment to Lifestyle Changes

Weight loss surgery is not a quick fix—it requires a lifelong commitment to lifestyle changes. Patients must be prepared to:

Follow strict dietary guidelines post-surgery
Adopt a healthy lifestyle with regular physical activity
Attend follow-up appointments and support programmes

5. Metabolic Syndrome

Metabolic syndrome is a combination of diabetes, high blood pressure, and obesity, which significantly increases the risk of heart disease and stroke. Bariatric surgery can be a highly effective treatment for metabolic syndrome, even in patients who may not strictly meet the criteria for morbid obesity.

6. Mental Health and Emotional Readiness

Mental health is an important consideration for weight loss surgery. You may not be eligible if you have:
Untreated mental health conditions (e.g., severe depression, schizophrenia)
Active alcohol or drug dependency
An eating disorder that is not managed

Tonic Weight Loss Surgery provides comprehensive psychological support to ensure patients are mentally prepared for surgery and long-term lifestyle changes.
