Anemia is a serious condition
that can make a person feel tired and weak and
can lead to serious heart problems and other health
complications.
The good news is anemia can be treated and people
may regain their independence and go on to live
healthier, more productive lives.
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.
