Doctor’s Note
Dr Muhammad Usman, MBBS
22 stone is a weight where I think it is important to be direct but compassionate. The health risks at this level are clinically significant and include elevated risk of Type 2 diabetes, sleep apnoea, hypertension, and joint deterioration. At the same time, the options available in 2026 are more effective than at any previous point. Bariatric surgery, when accessed through the right pathway, produces durable 25 to 35 percent weight reduction in most patients. For someone at 22 stone who has not yet explored this with their GP, it is a conversation worth having.
