I have studied your mail in detail. The cause of anemia is many, but in your case and the detail provided by you, it can be due to:1. Kidney disease related anemia: S. creatinine is 1.6 which is higher than the normal value. Kidney releases Erythropoietin which is required for formation of RBCs.2. May be due to anticoagulant Chat Doctor. Try to investigate it by urine RE, stool for occult blood, Done your INR test which will confirm your blood thinning and helps in managing your dose of anticoagulants. 3.
