There are several possible reasons for your extreme feeling of fatigue, here are a few that I know of.. although there are others so it would be best if you talked this over with your doctor to find out exactly what is going on with you.
Ok here is my opinion, lol:
If you have an infection you can feel extremelty lethargic and wiped out all the time.
Mono can make you feel like this too.. and it is contagious so easily picked up from a ton of places.
Anemia can make you feel like you are not sleeping at all!
Depression can make you feel tired and listless.
Sleeping TOO MUCH can make you feel exhausted.
Being inside and unactive for long periods of time can make you feel this way.
The more active you are, the more energy and less tired you will feel.
My biggest 2 things here are the infection and the depression.. had them both! They both suck! Still, I would get in to see the doctor as soon as you can and find out what is going on so that you can start to feel good again.. when you feel tired all the time something is NOT right!
Hugs!

thanks. even tho i hate going into seeing my doctor, my head feels so heavy from fatigue that it hurts, so i guess ill just have to go in whether i want to or not, because right now, i cant seem to function.

Fatigue is part of HS. Simple reason. HS is autoimmune. Your body is constantly fighting something it can't win. Just like when you have the flu, you are tired, because your immune system is fighting. With HS before and during flares you will be tired. I live in flares and I'm tired all the time. Research autoimmune, it effect a ton of things in your body including muscles and everything just by it being an autoimmune disease.

I know my HS (along with the fibromyalgia, depression,Chronic Fatigue,PTSD,Degenerative Disc Disorder/Disease(however they choose to classify this this year) makes me tired, especially if I am battling an infection and/or depressed.
Like RebeccaV said, make sure to check with your doctor to make sure that that truly is the cause of tiredness. I know I did the anemia test, tried to stay as active as possible, had doc check for stuff like mono or other invaders..I finally gave up and chalked it up to all the above mentioned and the ugly combo they make.
It very well could be, but do check with a doctor to make sure it is nothing else. An ounce of prevention is worth a pound of cure. Better to know if it is something else and be able to take care of it, or at least take it down a peg or two if getting rid of it isn't possible, than to sit and suffer.
I'm tired and achy all the time, and even though I try to get 8 hrs sleep (and let me tell you, it is hard for me to do so sometimes with a 9yr old boy with full on ADHD) I always wake up feeling like I haven't been to sleep at all. But at least I know I'm trying, and that all this is the HS (for me) doing its thing.

I used to be tired all of the time like this, but I decided to try the gluten-free thing partially and cut down on dairy and fat. I lost a few lbs and that has eliminated the fatigue for me. My kids are so shocked that I am up cleaning and cooking that they are trying to get 100% advantage out of it...can we go here..can we go there. It's worth a try to tweak your diet a lil.

All i know is that im tired all the time too. I feel like i can just sleep and sleep no matter what.

I am so glad someone asked this question. I was just going to do so myself, so I am glad someone else feels like I do. I am tired all the time. I fall asleep at my desk at work almost daily. I hate that I do it, but I feel like I cant help it. I was also wondering if it was the HS, I figured it probably was, but wasnt sure. Thanks for asking this question. :o)

I am tired all the time. Fatigue has become my way of walking through the world. I have had trouble sleeping since menopause kicked in.

I too struggle with Insomnia. Some days I only get 1 or 2 hours of sleep even though I have taken over the counter and prescription sleeping pills. Some sleeping pills actually wire me up like I am on crack or something! LOL!
Being tired is a way of life anymore.

I am SO thankful for this discussion, I feel constantly fatigued as well. Having a young baby, along with 2 other children, doesn't help I am sure but I always chalked my fatigue up to being a busy mom/wife. I know I suffer from anemia at times, not continuously but it kicks in and out so I have to guess when I need my iron supplements. It has been suspected I have fibromyalgia because I suffer from unexplainable joint pain, the doctors don't have a clue what it is though. Anyhow, even though I am fatigued pretty well all the time, there are also times I have troubles getting to sleep. Even when I exercise more, it lifts my spirits however it doesn't eliminate the fatigue. I can get so bad that I have to stand so I don't fall asleep. If I sit, no matter where I am, I start getting the head nods (even if I had no obvious reason why I would be tired). When people I am with insist that I take a seat, I always answer with "no thank you, I have been sitting too much today and could use a stretch" because I don't want them to be insulted when I start to fall asleep or my eyes start to roll back in the middle of conversation. At times, my mind feels completely awake my body has difficulties getting mobile. I was worried telling anyone cause I would I am so glad this fatigue finally makes sense, I never put HS & fatigue hand in hand before but not sure why I haven't.

I have HS and I have had trouble with fatigue my entire life. I feel like I could just sleep sleep sleep all the time no matter what. Like someone else said, I walk through life feeling fatigued. I have just gotten used to it but I feel sick and have no energy ever. I find it hard to get up out of bed at times. I just always feel weak. And someone below was right, it truly is because your body is fighting an infection that it will never win against... If I had one choice or wish in my whole life it would be that I was not born with this disease.
