Lethargy is more than just feeling tired or sleepy—it's a significant medical symptom that can impact daily life and potentially indicate underlying health conditions. Understanding the medical definition of lethargy and its implications is crucial for recognizing when to seek professional help and how to manage this condition effectively.
This comprehensive guide explores what medical professionals mean when they discuss lethargy, its various causes, and how it differs from regular fatigue. We'll also examine when to be concerned and what steps you can take to address this condition.
