I have been really fatigued lately and I cannot pin it on any one thing in particular. I do have an appointment with my doctor next Tuesday for a follow-up.

Early last year I tried to lose weight. I started cycling and I actually gained weight. I thought that was strange, so I went to the doctor, got all sorts of tests to see if I had a thyroid condition, etc. - all tests gave me a clean bill of health. I joined a gym, worked with a trainer and nutritionist and finally I started seeing results. From January 2009 to now, I have lost about 40 pounds.

Now I am thinking, have I lost too much weight? I can fluctuate within 5 pounds of my target weight set for me by the gym. Is that why I am fatigued - is it too much for my system to handle? I often feel exhausted, sleepy. I barely need to do any workouts at all to feel that way. I rode to work twice last week (26 k ride return, all flat terrain), rode to work on Monday, I do ten minutes of abs, and 20 minutes of pm yoga. Forget about the swimming and running that I want to do, I don't have the energy.

I take vitamin supplements and I think I well, according to my nutritionist. And I go to bed at a decent hour, I am not a night owl.

I am 46 - it is frustrating not to be able to go like the Energizer bunny that I used to be in my 20s.

Anyone else have problems with fatigue?
