My doctors have asked me to see a rheumatologist. My symptoms include chronic ( 2 yrs) B12 deficiency with levels under or at 200. My primary complaint is chronic fatigue and I take flouextine 20mgs a day to manage depression. While on medication and with exercise I am not depressed. My RBC level is 3.65 which is under the 4-5.20 range, and my HGB is 11.9 also under the 12-16 range. I was diagnosed with post partum subacute hyperthryoiditis after my second pregnancy 7 years ago and this resolved on its own without meds in 8 months. I was diagnosed with borderline levels of gestational diabetes with my first pregnancy which was controlled with diet and exercise. My glucose level now is 89. BMI is 25.2 and I am an active (run 15 miles a week, lift weights and play soccer with my children and train my daughter in track), functioning professional and mom. I get 8 hours of sleep, yet I am exhausted. Could I have an autoimmune disease?
