Mom had heart operation lost blood now blood results are wbc 12.5 grn 10.2 rbc3.17 hgb9.1 hct26.3 she have a blood problem or is it from operatation?

Operation: Your mom had a heart operation and now has post operative anemia. This is very common. The doctors will look at how she is doing and if she feels ok then she may not require transfusion. If she is pale, short of breath then she might need blood. The next steps are rehabilitation and changing the habits which caused heart disease. No smoking, good walking everyday and low fat diet.

It depends: How long ago was the operation? What was her hematocrit before the operation? What are her vital signs? How does she feel? It could be expected from the operation.
