What Is the Cause of Low Blood Count in Elderly Patients?

The causes of low blood count in elderly patients include underlying diseases such as cancer or kidney failure, says WebMD. The patients can also be suffering from malnutrition. Renal insufficiency associated with age is also a cause of low blood count.

Other causes of low blood cell count in elderly people are the aging of stem cells and insufficient levels of androgens, says PubMed Central. Androgens are known to help the body manufacture red blood cells.

Low blood levels can also be a result of chronic inflammation in the elderly, states PubMed Central. Substances called cytokines, which are involved in inflammation, inhibit the production of red blood cells. Myelodysplasia, a condition where the blood cells are poorly formed or do not function well, is another cause of low blood levels, according to Mayo Clinic.
