Secondary polycythemia can result from
- chronic smokers
- long-term COPD
- long-term residency in high altitudes
- EPO treatment
Most common anemia
IDA
IDA symptoms
- fatigue
- exertional dyspnea
- glossitis
- angular chelitis
- pica
Severe IDA symptoms
- koilonychia
- systolic murmur
- tachycardia
- heart failure
IDA labs
- low ferritin
- low serum iron
- high TIBC
- high RDW
- MCV <80
- MCH <25
Medication for IDA
- ferrous sulfate 325 mg PO TID between meals
- take with vitamin C
- treat for 3-6 months to increase ferritin stores
Ferrous sulfate interactions
-avoid antacids, dairy, quinolones, tetracyclines
