Impact of GLP1 meds on amputees Looking for sources to provide perspective on the positives and negatives of GLP1 medications on patients with amputations. Particularly interested in hearing from physical therapists and rehabilitation professionals regarding loss of muscle mass related to GLP1 weight loss and how that impacts rehab as well as the fit of prosthetics. Nutritionists and dietitians who could speak to ways to mitigate muscle loss would also be great.

In my dermatology practice, I see a few patients with limb loss who use GLP-1 medicines for obesity or diabetes. When weight and glucose come down, their skin often calms down too. Fewer intertrigo flares. Less sweat trapped in the socket. Some tell me transfers feel easier because they are carrying less mass, and blood sugar swings stop hijacking rehab days. The tradeoff is body composition and fit. I found a 2025 clinical review that reports that roughly one quarter of GLP-1 weight loss can come from lean mass, and GI side effects occur in around 40 percent of patients. For an amputee, less thigh or calf volume can mean a loose socket, new shear, blisters, and stalled gait work. I ask PTs to prioritize resistance training and I push protein above 1.2 g per kg daily, split over meals, with early prosthetist visits.
