Doctor's Note - Written by Dr Muhammad Usman, MBBS
115 kg is a weight where the NHS and WHO care pathway has genuinely expanded in recent years. The eligibility criteria for GLP-1 medications and Tier 3 specialist weight-management services are met by most adults at this weight. I raise this not to push any specific route but because many patients at 115 kg are unaware of what is now available through their GP without a private referral. It is worth asking the question at a routine appointment rather than waiting for a crisis to prompt the conversation.
115 kg and the BMI 40 threshold - what it means
A BMI of 40 is the clinical threshold often discussed in the context of bariatric surgery eligibility. At 115 kg, the BMI of 40 is exceeded at every height up to approximately 5ft 7in. At 5ft 6in the BMI is 40.7. At 5ft 8in it drops to 38.4, below the 40 threshold. For adults between 5ft 4in and 5ft 7in, 115 kg produces a BMI in the 40 to 43 range - the lower end of Class 3 obesity. This is the BMI zone where NHS/WHO bariatric pathways typically become available.
