I am 48, F, normal weight.  had blood work for symptoms of extreme fatigue, lightheadedness, foggy brain, nausea and indigestion.  blood work ruled out thyroid issues, glucose normal, negative hepatitis A, B, C.  AST is 46, ALT 71, all else normal. positive for EPV, VCA is 3.63 and EBNA is 5.  Dr. said I could have had mono.  I had mono 27 years ago and I know antibodies stay in blood.  Does this mean I have mono now??  Did not have fever or sore throat.  Exercise regularly, no alcohol or drugs. This lethargy and tiredness definitely not normal.  Dr. just said to be retested in 6-8 weeks but very concerned it might be something other than mono.  Also have thickening of endometrium and large polyp that needs to be removed.  Can that be related to high liver enzyme levels?  Thanks!

If all tests are negative you may have a condition called chronic fatigue syn Chat Doctor.  This gradually resolves. Some studies have been conducted on the benefits of probiotic, so you may try sporran two tabs twice a day for eight weeks and see if that helps. If you don't have any medical problems that prevent you from exercises you may try graded aerobic exercises to improve your well-being. I presume that your blood sugar levels and thyroid are normal. You may also get your hemoglobin checked if that has not been done because low hemoglobin called anemia may cause fatigue and lightheaded feeling. Since you mentioned uterine polyp, polyps may cause chronic blood loss which may cause anemia, so hemoglobin test is essential. You may get the polyp removed as per your doctors' advice etc. Regarding nausea and indigestion you may do a test called H.pylori breath test or Urea breath test. This is a simple test to detect H.pylori gastritis and if positive you may be treated for it as well. Best regards
