Anemia is defined as a drop in haemoglobin (Hb), hematocrit (HCT), or red blood cell (RBC) count. Anemia is a widespread issue in primary care, and primary care physicians are generally the first to notice its symptoms. Anaemia is a prevalent clinical concern among the adolescents.  It is widely known that haemoglobin levels drop with age increase. Anemia has been linked to a variety of negative effects, including higher mortality, hospitalisation, and a worse quality of life. epidemiological reporting of anaemia is fragmented. Anemia is diagnosed in part by symptoms reported in general practice/family medicine (GP/FM). Management of anemia relies on the type of anemia and underlying cause, in this review we will be looking at Prevalence, etiology, classification and management of Anemia.
