GLP-1 receptor agonists cause fatigue primarily through indirect mechanisms including substantial caloric restriction from appetite suppression, gastrointestinal side effects leading to dehydration and nutritional deficits, and metabolic adaptation during weight loss
The triggers of activating self-reactive clones are still to be determined, but may be common infections, molecular mimicry, or inflammation signals from gut microbiota (Westall, 2006)
While it also presents gastrointestinal side effects, its profile appears significantly more manageable and cleaner regarding liver safety signals, demonstrating a better balance of efficacy and tolerability
