Energy and fatigue
Post-viral fatigue and long COVID
Fatigue can persist after infection and may include delayed symptom worsening after activity, brain fog and autonomic symptoms.
Potential benefits explored
Improved function after a viral illness.
MOTS-c and SS-31 reflect energy hypotheses, while TA1 and VIP reflect immune/vascular research. No single mechanism explains every post-viral symptom pattern.
Practical interpretation
Assess post-exertional malaise and autonomic symptoms. Use an individual energy-management approach where activity triggers delayed worsening; see ME.
Meaningful outcomes: Daily function, orthostatic symptoms and post-exertional worsening.
