Background:Long COVID refers to persistent symptoms lasting weeks or months after recovery from acute COVID-19. These symptoms can affect multiple systems and impair quality of life.Objective:To assess the prevalence, pattern, and probable pathophysiological mechanisms of long COVID symptoms in recovered patients.Materials and Methods:A cross-sectional study was conducted over 12 months among 210 adults recovered from COVID-19 (>= 12 weeks postinfection). Clinical evaluation, lab investigations, and imaging were used to identify post-COVID symptoms and explore underlying mechanisms.Results:Common symptoms included fatigue (67.6%), breathlessness (42.8%), cognitive issues (39.5%), and myalgia (34.7%). Neuropsychiatric complaints were noted in 41%, while 29% had cardiopulmonary sequelae. Elevated inflammatory markers correlated with symptom persistence (P < 0.05).Conclusion:Long COVID involves diverse symptoms, primarily fatigue and neurorespiratory complaints. Immune dysregulation and systemic inflammation appear central to its pathophysiology.
