Other than being absolutely exhausted, I have elevated lipase and amylase. No other symptoms. Docs have checked and tried several things: thyroid, iron and potassium levels, gallbladder, depression, mono, hormones...
I have trouble making it through the day! I have considered asking to have my heart checked, but I don't really have any symptoms to. I'm in my 20's and 110 lbs. I'm not dieting any special way, and I get minimal exercise.
Lipase and amylase are usually tests for pancreatitis. I would think you'd have other symptoms tho? I'm not sure. Were you in some kind of accident in the past few years where you might have bruised or injured your pancreas? http://www.nlm.nih.gov/medlineplus/ency/article/000287.htm
I assume your docs checked for anemia (a complete blood count & B12 level, not just iron). Chronic fatigue in a young woman, anemia would be the #1 suspect.
Other stuff that can increase lipase and amylase: kidney problems, medications (estrogen, Volaren, prednisone), past or present viral infections and sometimes Celiac disease.
(I have Celiac. You can have Celiac and have no symptoms, there's a simple blood test for it)
