anemic definition and symptoms
According to research from the National Heart Lung and Blood Institute (NHLBI), anemia is taxing on the cardiovascular system (and heart) due to the fact that the body requires iron to produce hemoglobin, an essential substance that transports oxygen from the lungs to the various tissues and organs. Lack of oxygenated blood will result in extreme fatigue, inadequate oxygen delivery by the cardiovascular system and, over the long term, eventual damage to the body’s organs (i.e., brain and heart). Because there are low numbers of red blood cells, not enough oxygen reaches the body's tissues. Symptoms of anemia include: 1  weakness and fatigue. 2  pale skin. 3  shortness of breath with physical activity. 4  lightheadedness or dizziness.  rapid heartbeat. Decreased oxygen delivery to the tissues and organs will dramatically affect the cardiovascular system and it’s related muscle tissues. Patients with anemia produces a drastically decreased number of red blood cells, which don’t contain adequate hemoglobin for blood oxygen transport. Anemia is a condition in which you don't have enough healthy red blood cells to carry adequate oxygen to the body's tissues. Having anemia may make you feel tired and weak. There are many forms of anemia, each with its own cause. Anemia can be temporary or long term, and it can range from mild to severe. See your doctor if you suspect you have anemia because it can be a warning sign of serious illness. Treatments for anemia range from taking supplements to undergoing medical procedures. What is iron deficiency anemia? Anemia occurs when you have a level of red blood cells (RBCs) in your blood that is lower than normal. Iron deficiency anemia is the most common type of anemia, and it occurs when your body doesn’t have enough of the mineral iron. Your body needs iron to make a protein called hemoglobin. Because there are low numbers of red blood cells, not enough oxygen reaches the body's tissues. Symptoms of anemia include: 1  weakness and fatigue. 2  pale skin. 3  shortness of breath with physical activity.  lightheadedness or dizziness. Blood contains red cells, white cells, and platelets. The red blood cells (RBCs) carry oxygen throughout the body. Men have about 5.2 million red blood cells per cubic millimeter of blood, and women have about 4.7 million per cubic millimeter of blood. Anemia means an abnormally low number of red cells in the blood. Because there are low numbers of red blood cells, not enough oxygen reaches the body's tissues. Anemia is diagnosed by a blood test called a complete blood count (CBC). A blood sample is taken and its amount of red blood cells are measured. The symptoms of iron deficiency anemia can be very mild at first, and you may not even notice them. According to the American Society of Hematology (ASH), most people don’t realize they have mild anemia until they have a routine blood test. The symptoms of moderate to severe iron deficiency anemia include:
Anemia means an abnormally low number of red cells in the blood. 
Symptoms : 1 weakness and fatigue. 2 pale skin. 3 shortness of breath with physical activity, lightheadedness or dizziness.
