3. Overall Fatigue
Being tired isn’t quite the same thing as feeling fatigued. When you’re tired, you can usually get some sleep or have a power nap for a few minutes and you’ll feel much better when you wake up from either – but when you’re fatigued, nothing you do appears to make a difference for the real level of tired you are. Fatigue is a serious medical symptom on its own, and it can almost always mean that there’s something wrong in your body.
Parasites like giardia have the ability to feed off the nutrients that would otherwise go to essential processes in the body: This often extends to the energy that your body would need during the day to perform certain tasks.
With this energy taken up by a parasite instead, overall fatigue is a very common symptom seen with many parasitic infections. Treating the infection will usually take care of the associated fatigue or sleepiness.
