What kind of doctor treats Hemolytic Anemia?

A hematologist, a doctor who treats blood diseases, usually manages hemolytic anemia. Treatment depends on the cause, so other doctors may help too. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is hemolytic anemia?

Hemolytic anemia is a blood condition. Your red blood cells are destroyed faster than your body can replace them. It can develop quickly or slowly, and it can be mild or serious.

Red blood cells carry oxygen to the body. Normally, they last about 120 days. In people with hemolytic anemia, they are destroyed earlier than normal.

Your bone marrow, the soft tissue in the center of your bones, makes new red blood cells. In hemolytic anemia, it cannot make enough of them to replace the ones being destroyed.

Symptoms

You may not have symptoms if the anemia is mild. If the problem develops slowly, the first symptoms may be:

  • Feeling weak or tired more often than usual, or with exercise.
  • A pounding or racing heart.
  • Headaches.
  • Problems concentrating or thinking.

If the anemia gets worse, symptoms may include:

  • Lightheadedness when you stand up.
  • Pale skin.
  • Shortness of breath.
  • A sore tongue.
  • Pain in the left upper belly from an enlarged spleen.

The spleen is an organ that filters blood. A spleen or liver that is larger than normal can also be a sign.

Causes and who gets it

Red blood cells can be destroyed too early for several reasons. These include:

  • An autoimmune problem, in which the immune system mistakenly sees your own red blood cells as foreign and destroys them.
  • Inherited blood conditions such as sickle cell disease or thalassemia.
  • Defects in the hemoglobin inside red blood cells. Hemoglobin is the iron-rich protein that carries oxygen from the lungs to the rest of the body.
  • Infections.
  • Some medicines, and exposure to certain chemicals and toxins.
  • Bone marrow failure.
  • Blood clots in small blood vessels.
  • Faulty, damaged, or artificial heart valves.
  • A blood transfusion from a donor whose blood type does not match yours.

Anyone with one of these problems can be affected. Mild cases may cause no symptoms.

How doctors diagnose it

Your doctor will do a physical exam and order blood tests. A complete blood count (CBC) can help diagnose anemia. It also gives hints about the type and cause of the problem.

Other blood tests can identify the type of hemolytic anemia. These include a Coombs test, a reticulocyte count, and tests for haptoglobin and lactate dehydrogenase (LDH). Your doctor may also order a urine test, a bone marrow test, or genetic tests.

Treatment

Treatment depends on the type and cause. If your anemia is mild, you may not need treatment. Others can often be treated or managed. Options include:

  • Blood transfusions. In emergencies, a transfusion may be needed.
  • Medicines. For immune causes, medicines that suppress the immune system may be used.
  • Extra folic acid and iron supplements, when blood cells are being destroyed fast, to replace what is being lost.
  • Surgery to remove the spleen. This is needed only in rare cases. The spleen filters abnormal cells out of the blood.
  • Blood and bone marrow transplants.

If a medicine or another health condition is the cause, your doctor may change your treatment to manage or stop the hemolytic anemia.

When to see a doctor

Contact your health care provider if you develop symptoms of hemolytic anemia, such as unusual tiredness, a racing heart, or pale skin. Serious hemolytic anemia that is not treated can cause irregular heart rhythms and heart failure.

Call 911 or go to the emergency room if you have severe trouble breathing, chest pain, or fainting.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can do a first exam, order blood tests, and refer you to a blood specialist. They can also help keep track of your symptoms and your care over time.

Common questions

Is hemolytic anemia serious?

It can be mild or serious. Serious hemolytic anemia that is not treated or managed can cause irregular heart rhythms, a heart that is larger than normal, and heart failure if the anemia gets severe.

Does hemolytic anemia always cause symptoms?

No. You may not have symptoms if the anemia is mild. Symptoms can include tiredness, dizziness, weakness, and a spleen or liver that is larger than normal.

Can hemolytic anemia be treated?

Yes, it can often be treated or managed. Treatment depends on the type and cause, and may include blood transfusions, medicines, or surgery to remove the spleen.

Why do red blood cells break down too early?

Red blood cells can break down too early for several reasons. They include autoimmune problems, inherited blood conditions, infections, some medicines, and mismatched blood transfusions.

Does hemolytic anemia need surgery?

Rarely. In rare cases, surgery is needed to take out the spleen, an organ that filters abnormal cells from the blood.
