1. A medical system, comprising:
- an implantable sensor including circuitry configured to sense blood viscosity and to generate a signal modulated by the blood viscosity;
implantable circuitry configured to receive the blood viscosity signal and to store the blood viscosity; and
an anemia module coupled to the implantable circuitry, the anemia module configured to compare the blood viscosity to one or more thresholds associated with hematocrit, to determine an anemia status of a patient based on the comparison, and to store a trend of the anemia status over time.

Abstract
Methods and systems for implantably determining a patient'"'"'s anemia status and treating anemia are described. Blood viscosity is compared one or more thresholds to determine a patient'"'"'s anemia status. Therapy, in the form of electrical stimulation therapy or administration of a pharmaceutical delivered to the patient'"'"'s kidneys or hypothalamus is controlled based on the anemia status.

21. An implantable medical system, comprising:
-
an implantable sensor configured to sense blood viscosity; an anemia module configured to compare the blood viscosity to one or more thresholds respectively associated with one or more hematocrit levels and to determine an anemia status of a patient based on comparison of the blood viscosity to the one or more thresholds, and wherein the anemia module is further configured to detect hemodilutional anemia and to detect an onset of a heart failure decompensation event based on the detection of the hemodilutional anemia; and a therapy module configured to control an electrical stimulation therapy delivered to one or both kidneys or a hypothalamus of the patient based at least in part on the anemia status.
