I’m a 22-year-old female with history of mild IDA, gastritis, and Vitamin D deficiency. Last spring, I noticed I was suffering from fatigue, some GI discomforts, lots of hair loss... just feeling rundown and unusual malaise. I have had CBCs done in the past, and WBC was always normal. Then, in May 2017 it was picked up as low. Then again in months following. Now, over a year later and I still have a low total WBC count. Wondering what could be causing it.
