Acute sarcopenia in post-COVID-19 patients is driven by a multi-factorial mechanism involving hyper-inflammatory cytokine storms, mitochondrial dysfunction, and immobility, leading to rapid muscle mass and strength loss.
If you have recovered from severe COVID-19, expect some muscle loss due to the illness's inflammatory impact. Prioritize early nutritional support (high protein) and gradual, supervised physical rehabilitation to counteract this loss, rather than assuming it is permanent.
ModerateSupportsMEDIUM confidence
COVID-19 is as a multi-organ infectious disease characterized by a severe inflammatory and highly catabolic status, influencing the deep changes in the body build, especially the amount, structure, and function of skeletal muscles which would amount to acutely developed sarcopenia.
Why this rating
The paper is a review article synthesizing observational studies and mechanistic hypotheses rather than a single controlled trial.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
