Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells carry oxygen to the body’s tissues and organs. Without enough healthy red blood cells, the body cannot get the oxygen it needs to function properly. There are many different types of anemia, each with its own cause. Some types of anemia are temporary and can be treated with simple measures, such as taking iron supplements. Anemia can range in severity from mild to life-threatening, depending on the underlying cause.
There are many different ways to check for anemia. A doctor will typically start by asking about your symptoms and medical history. They will also perform a physical exam. Blood tests are the most common way to diagnose anemia. A blood test can measure the number of red blood cells in your blood, as well as the amount of hemoglobin in your red blood cells. Hemoglobin is the protein in red blood cells that carries oxygen.
