What is Anemia
According to the U.S. Centers for Disease
Control and Prevention (CDC), anemia affects
approximately 3.4 million Americans, people of
all ages and from all walks of life.
The blood in our bodies is composed of three
types of cells (red blood cells, white blood
cells, and platelets) that circulate throughout
the body. Red blood cells contain hemoglobin (Hb),
a red, iron-rich protein that carries oxygen
from the lungs to all of the body's muscles and
organs. Oxygen provides the energy the body
needs for all of its normal activities. Anemia
occurs when the number of red blood cells (or
the Hb in them) falls below normal and the body
gets less oxygen and therefore has less energy
than it needs to function properly.
Anemia may become worse if it is not treated,
and it can lead to potentially serious, even
life-threatening complications. When the number
of red blood cells decreases, the heart works
harder, pumping more blood to send more oxygen
throughout the body. If the heart works too
hard, it can develop a rapid heartbeat
(tachycardia), and/or another serious condition
known as left ventricular hypertrophy (LVH), an
enlargement of the heart muscle that in turn can
lead to heart failure.
Sings and Symptoms
Anemia can be difficult to identify because
early symptoms may be mild. In addition, it is
easy to mistake some symptoms of anemia for
symptoms of serious disease or medication side
effects. As symptoms of anemia worsen, however,
they can significantly affect a person's quality
of life.
Anemia can make it hard to find the energy to
enjoy hobbies or other leisure activities, or
even to complete basic tasks at home or at work.
Particularly for a person with a serious
disease, the fatigue, weakness and other
symptoms associated with anemia can compound the
challenges of coping with the serious disease.
Major symptoms of anemia include:
-
Extreme fatigue
-
Weakness
-
Shortness of breath
-
Confusion or loss of concentration
-
Dizziness or fainting
-
Pale skin, including decreased pinkness of the
lips, gums, lining of the eyelids, nail beds and
palms
-
Rapid heart beat (tachycardia)
-
Feeling cold
-
Sadness or depression.
