Have you ever wondered what gives blood it's rich red color? It's the hemoglobin, which is an iron-rich protein in red blood cells that enables blood to carry oxygen to every nook and cranny of your body. Despite the importance of hemoglobin to keep everything running smoothly, some people, explains the National Heart, Lung, and Blood Institute (NHLBI), lack adequate amounts of red blood cells and/or hemoglobin, which can result in anemia.
While there are many different types of anemia, some common symptoms include fatigue, shortness of breath, dizziness, headaches, coldness/numbness in hands or feet, pale skin, and chest pain; as well as low body temperature, rapid or irregular heartbeat, irritability, and poor performance at work and/or school.
Nearly 3 million people from all walks of life live with anemia in the U.S., although WomensHealth.gov explains that women of child bearing age are at particular risk, along with growing infants and toddlers who drink a lot of cow's milk, pregnant women, and female athletes who engage in vigorous exercise regularly. Factors that might increase a person's susceptibility to anemia, according to NHLBI, include:
· Eating a diet low in vitamins, iron, and other minerals
· Blood loss from surgery or injury
· Long-term, serious illness or infection
· Family history of inherited forms of anemia, like sickle cell anemia or thalassemia
The consequences of untreated anemia extend far beyond feeling tired and sluggish. Severe, long-lasting anemia can result in heart failure; damage to the liver, brain, and other organs; and even fatal fluid loss. Many cases of anemia may be treatable with simple lifestyle changes, so talk to your doctor about getting tested, whether or not you are experiencing symptoms.
