I have low white blood cell count which has been going on for years because I believe it is caused by chronic lack of sleep.  Is this true?  I am 60 yrs old and I also have a problem with loosing weight.  I sleep very little about every third day.  I take Lunesta 10 times per month because of insurance regulations.  I need more than that.
Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Yes, Sleep disturbance can cause stress, which can affect WBC count.2. Along with sleep disturbance, malnutrition will be seen. Malnutrition can lead onto It B12 deficiency which can affected all cell counts, including WBC.3. However, if WBC count is only mildly reduced, not to worry. If it is less than 2000 cell/CMM, then bone marrow biopsy will be necessary for further evaluation. Hope it helps. Any further queries, happy to help again.
