Fatigue
Dec 15, 2004

What is the definition of fatigue and how does it differ from just being tired? Does fatigue also indicate weakness in the limbs, a general feeling of uneasiness, or feeling drowsy? Or is fatigue far more than this and if so, how would one recognize fatigue for what it is and get treated accordingly?

Thanks,

drowsy, weak, but not sure if fatigued!!!

Response from Dr. Frascino

Hi,

Fatigue is a general term used to describe feelings of exhaustion, sleepiness and lack of energy, a common problem for those of us who are "virally enhanced." While the concept of fatigue may seem obvious in everyday usage, there are actually several medical definitions of the term. Specialists in the field indicate that fatigue is multidimensional and may include:

1. Physical fatigue, which refers to unusual tiredness after physical exertion.

2. Mental fatigue, which is difficulty focusing on activities that require concentration.

3. Motivational fatigue, which is defined as a lack of will or desire to engage in emotional or physical activities.

More generally speaking, fatigue is a subjective experience of low energy, weakness and/or sleepiness that may affect daily activities.

Perhaps my favorite definition explaining the differences between "tired" and "exhausted" came from a fortune cookie. It read: "Man who run behind car get exhausted but man who run in front of car get tired."

If you're feeling "drowsy and weak," talk to your HIV specialist. He/she will check it out for you.

Hope you get your pep back for the Holidays.

Dr. Bob
