Sudden Fatigue

Q: What is sudden fatigue?

Sudden fatigue describes the rapid, unexpected onset of exhaustion — where energy drops sharply without warning rather than gradually declining through the day. It can occur as a post-meal phenomenon (reactive hypoglycaemia, where insulin overshoot after a high-carbohydrate meal drops blood sugar rapidly), during or after vigorous physical activity in those with cardiac or respiratory compromise, as a feature of orthostatic hypotension (blood pressure dropping on standing), during viral illness as immune activation diverts resources, or as a postural tachycardia phenomenon in POTS (where standing produces a rapid heart rate and sudden fatigue). In ME/CFS, sudden fatigue following previously well-tolerated activity is part of the post-exertional malaise pattern.
