What does fatigue mean in a medical context?

Fatigue in the medical world means feeling very tired and not having enough energy to do things. It can be caused by many things, like not getting enough sleep, working too hard, or being sick.

Types of Fatigue

1. Physical Fatigue: This is when your body feels tired. You might feel like your muscles are weak and you can't do things you usually do, like playing or running.
2. Mental Fatigue: This is when your mind feels tired. It might be hard to think clearly, pay attention, or remember things.

Causes of Fatigue

• Lack of Sleep: Not sleeping enough can make you feel tired all the time.
• Illness: Being sick, like having a cold or the flu, can make you feel worn out.
• Stress: Feeling worried or stressed can also make you feel very tired.

Fatigue is different from just being sleepy. Sleepiness is when you feel like you want to go to sleep, but fatigue is when you feel like you can't do things even if you're not sleepy. If you feel very tired for a long time, it's important to talk to a doctor to find out why.
