what diuretics cause low white blood cell count? age 64, female, height 5 feet 9 inches, weight 152 pounds.  Taking 1/2 of a 37.5 mg tablet of HCTZ daily for a mild diuretic.  White blood cell count is 3 to 3.8, variable. Been that way for 3 or 4 years.  The rest of the hemogram is normal. Negative medical history otherwise, except for hypothyroidism.  Exercise regularly.  Eating healthy diet, low in fat, lots of veggies and fruit.
Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Diuretics do not affect WBC count.2. If there is no infection, not to worry about WBC count. Its only lower limit of normal. 3. Hypothyroidism, can cause low WBC count. Once corrected, it should have improved. It would have also caused anemia and low platelet count.4. Take it B12 and folic acid supplements, it will help in improvement. Not to worry about WBC count, It's still good. Hope it helps. Any further queries, happy to help again.
