Fatigue after attack?

The day after I have an IBS attack (usually in the evenings) of diarrhea, I feel completely drained and exhausted.  I don't know if its the attack itself or the anxiety with it but the next day I'm wiped out.  Does anyone else feel this way? Is this normal for IBS? Does anyone know why it happens?

Just wanted to reply b/c I have "chronic fatigue" pretty much every day, at least this past year due to increased activity (major UC flare). Even if my diarrhea is minimal a particular day (1-2X day), I still have pain after eating and cramping, so, yah, I'm fatigued. I sometimes feel like I'm walking around all day under water or on sand, you know, the effort of it all. I started an exercise program awhile ago--always kept as active as physically possible, but this time specifically to increase energy--and although my stamina is good and my body feels somewhat stronger, it has done very little for the consant fatigue I feel. I do it anyway, because it can't hurt. I've had IBS for approx. 20 years and ulcerative colitis for approx. 10 yrs, the fatigue part wasn't too bad until about 4 years ago, maybe it's b/c of how long I've been dealing with all of this?

I agree with Canyon. Many people experience fatigue and most of the time there is an underlying cause and its important to get it checked out. If you don't feel better after ingesting what Canyon suggested, it might be a good idea to talk with your doctor.

My doctor told me the fatigue is because your body has just riddled itself of all the nutrients it needs. You need to restore the potassium, magnesium and calcium in your body. Also, water and have something salty.
