Too fatigued to function
My boyfriend is 52 years old and had some serious health issues over the last two years. In Feb. of 2006 he had surgery to repair an aneurysm that was discovered on his ascending aorta. Fortunately it was found before it ruptured. The area was repaired with a 6 inch piece of gortex. He also received a mechanical valve at this time, as two of the three flaps were fused together. He is dealing with fatigue that is almost dibilitating at certain times and I don't know where to begin...
1) His heart is healthy and all arteries are clear.
2) He is about 50 lbs. overweight.
3) He takes coumedin (a blood thinner) for the mechanical valve.
4) He takes meds for blood pressure and cholesterol.
5) He takes a multi vitamin and Omega 3
6) We have been to a nutritionist and eat very healthy and correctly (for the most part!)
7) He exercises when he isn't too tired.
8) He uses a C-PAP machine for sleep apnia.
I realize that the weight and meds contribute to fatigue, but I have seen much heavier people with more energy than him. He is trying to lose the weight, but with a slow metabolism, it's impossible without regular exercise. Is there a way to know if there is an underlying cause for the fatigue without losing the weight and getting off the meds (except coumedin) first? Maybe a new approach???
