What is Hemolytic Anemia and Why Should You Care?
Published: Jul 11, 2024
Hemolytic anemia is a condition where red blood cells are destroyed faster than they can be replaced. This can lead to fatigue, weakness, and other health issues if left untreated.
Understanding Red Blood Cell Lifespan
Red blood cells typically live for about 120 days, traveling throughout your body to deliver oxygen. During this time, they face many challenges like squeezing through tiny blood vessels and battling oxidative stress. Your body normally replaces about 1% of red blood cells each day. In hemolytic anemia, this process speeds up dramatically.
Signs and Symptoms
Common symptoms of hemolytic anemia include fatigue, weakness, pale or yellowish skin, and shortness of breath. You might also experience dizziness, rapid heartbeat, or dark urine. If you notice these symptoms, especially if they come on suddenly, it's important to see a doctor.
Causes and Types
Hemolytic anemia can be inherited or acquired. Inherited types include conditions like sickle cell disease or thalassemia. Acquired types can be caused by infections, autoimmune disorders, or certain medications. Sometimes, the cause is unknown.
Diagnosis and Treatment
Doctors diagnose hemolytic anemia through blood tests, looking at red blood cell count, shape, and other factors. Treatment depends on the cause and severity. It may include medications, blood transfusions, or in some cases, removal of the spleen.
