What is a common symptom observed in CFS patients regarding exercise?

In Chronic Fatigue Syndrome (CFS), a characteristic symptom is the significant fatigue and exacerbation of other symptoms that occurs after even minimal physical exertion. This phenomenon, often referred to as post-exertional malaise, is a hallmark of the condition. Patients may find that activities that once felt manageable become overwhelmingly exhausting and can lead to a prolonged worsening of their overall health and well-being.

Unlike in healthy individuals, where exercise typically leads to improvements in stamina and energy levels, those with CFS might experience a severe decline in their ability to perform physical tasks and could need extended periods of recovery after such activities. This unique response to exercise is a crucial aspect of managing CFS, as it highlights the importance of balancing activity and rest to prevent further fatigue and symptom worsening.
