Tired all the time with no energy at 23 years old!

My first thought is that you are eating something (or things) that your body is sensitive to. Gluten and dairy are top offenders. Food intolerances have a huge effect on energy levels.

Get a second opinion. I am on medication for Hypothyroidism even though my levels are normal (high, but normal) I showed symptoms and my numbers for Hashimoto's disease are through the roof so my doctor decided to medicate. Did you see an endocrinologist? Can you be referred to one? Good luck, I hope you find out what's going on, because it isn't normal!

I would get a second thyroid test and make sure you get a copy of the results. There are varying opinions among doctors as to what a "normal" thyroid range is, but your TSH level should be no higher than 2. I say this because I had a similar problem and it turned out to be hypothyroidism, but at first my doc didn't think it was an issue. I got on thyroid meds and felt much better.

Not saying this is your problem, it could be a lot of different things - but I do think it's worthwhile having another test done and make sure you look at the results yourself.

ok, simple thing to try out if its sleep apnea.
tape two tennis balls to your back.

this will force you to sleep on your side or stomach. then your airway won't collapse at night.

I didn't read all the responses just yet, but maybe it's something like sleep apnea or something. There are several things that can cause it. It's you know you are eating properly and exercising. Not sure if you take a vitamin or not, if not, start!

I do know a common cause is Thyroid, and unfortunately, the test may be inaccurate. I think I'd get serious with your doctor about this and if s/he doesn't seem to know or care to dig deeper, then get a second opinion.

That sounds like mono......
I'd see anther doctor. And keep pushing yourself to workout do cardio everyday. I would always use that excuse am too tiered or fatigued to workout. BUt after 3, 4wks of doing it all the time I felt way better. Start off with jumping jacks ot get your heat beat up... HOpe you feel better and figure out what's causing it..

I have natural red hair and used to have the same problem, it was a vitamin D deficiency.

Did they run other tests with your blood? Did you recently start taking any new medications?

Sorry to hear about this! I'd definitely go straight to a specialist, or else see another doctor.

Best of luck.

Aside from the previously mentioned sleep apnea, two other possibilities come to mind just off the top of my head. One is Chronic fatigue syndrome. The other is Celiac's (aka Celiac's Sprue), which often results in a misdiagnosis of Chronic Fatigue Syndrome.

And I agree with the advice to get a second opinion.

Celiac was actually my first thought, lol.

Wow, this is me exactly! I'm not sure it matters, but I'm also a redhead, and 23. I have had sleep studies, and thyroid tests, and taken depression meds, you name it. It is so frustrating because I used to be very, very active. I've been to a few doctors and most of them just gave me grief since I'm so young. I had one outright accuse me of drug seeking. (I'm in graduate school and got a whole speech about how I shouldn't use ritalin, etc. to make it through school. I was pretty pissed.)

It has contributed to about a 30 pound weight gain, and is the main reason I'm here at MFP. I've had one doctor speculate that its due to the mono I caught my freshman year of college. I'm considering getting a test for gluten intolerance/celiac. (My dad has some weird food allergies)

I can't really help you out a lot, but compared to how I was doing a year or so ago, I'm much better, even though not back to where I was. I cut out almost all of my dairy. I've always been somewhat lactose intolerant, but loved milk so much that I was willing to suffer the consequences. I finally noticed that I seemed more sluggish after drinking milk, and dropped it fast. I have a super strict sleep schedule. I need to sleep at least 9-10 hours a night and I try to go to bed at the same time every night and wake up at the same time. Lastly, and this was the hardest, I cut out most of my caffeine. I was chugging a soda about every hour a so just to have the energy to make it through the day. This ended up causing me about a grand in dental bills because the acid screwed up my teeth. After the first two weeks, I notice some improvement in my energy.

If you need someone to talk to, feel free to message me. Most of my family and friends just can't really understand. I don't think my parents really got it until I visited them and slept almost 2 days straight, just getting up for a couple of hours when they made me. Luckily, I hardly ever do that now, but I do still sleep a lot more than most.

Edit - Also, are you taking any multivitamins with iron? Iron deficiency anemia can cause serious fatigue problems and is actually a symptom of celiac's disease.

You NEED to see a doctor. There are any number of diseases, conditions or syndromes that can cause this.

You obviously did not bother to read anything other than the title to this thread

Actually I did. I suppose I should have said "another" or "a real" doctor. I find it hard ot believe that any certified doctor would say this is all due to red hair, which is complete nonsense. And if s/he did then I'd report them.

My thoughts exactly. I mean really, what kind of doctor tells someone that suddenly feeling like crap is because of their hair color. Surprised he didn't say you are Irish so you ought to be deinking more.
