This is a narrative review (a summary of existing research rather than a new study) that examined long-term effects of COVID-19, with a focus on post-exertional malaise (PEM) and postural tachycardia syndrome (POTS). The authors report that in people with post-COVID, PEM—a worsening of symptoms after exertion—was observed in approximately 86% of patients, and POTS-related symptoms in up to 82%. The review suggests pacing and symptom-focused treatments may help, though these are early findings from a narrative synthesis rather than definitive evidence.
