Why RDW CV Is High

RDW CV – An Overview

Red blood cells (RBCs) are the most numerous blood cells in our bodies, and they are responsible for carrying oxygen from the lungs to the rest of the body. The size and shape of RBCs can vary, and this variation is measured by a test called red cell distribution width (RDW). RDW is expressed as a coefficient of variation (CV), which is a measure of how much the size of RBCs varies.

RDW CV is usually between 11.5 and 14.5 percent. If your RDW CV is higher than this, it means that the size of your RBCs varies more than it should, a condition known as anisocytosis.

Causes of High RDW CV

There are many potential causes of high RDW CV, including:

Iron deficiency anemia: When you don’t have enough iron in your body, your bone marrow can’t produce enough healthy RBCs. This can lead to a high RDW CV because the RBCs that are produced are smaller than normal.

Vitamin B12 or folate deficiency anemia: Vitamin B12 and folate are essential for the production of DNA, which is a vital component of RBCs. If you don’t have enough of these vitamins, your bone marrow can’t produce enough healthy RBCs, leading to a high RDW CV.

Chronic diseases: Certain chronic diseases, such as kidney disease, liver disease, and thyroid disease, can cause a high RDW CV. This is because these diseases can interfere with the production of RBCs or the breakdown of old RBCs.

Inherited disorders: Some inherited disorders, such as sickle cell anemia and thalassemia, are characterized by high RDW CV. These disorders cause RBCs to be abnormally shaped or sized.

Medications: Some medications, such as chemotherapy and antiretroviral therapy, can cause a high RDW CV. This is because these medications can damage RBCs or interfere with their production.

Symptoms of High RDW CV

A high RDW CV is usually not associated with any symptoms. However, the underlying cause of a high RDW CV may cause symptoms, such as:

Fatigue

Shortness of breath

Pale skin

Chest pain

Headaches

Dizziness

Treatment for High RDW CV

The treatment for a high RDW CV depends on the underlying cause. If the cause is a vitamin or mineral deficiency, then treatment will involve taking supplements to correct the deficiency. If the cause is a chronic disease, then treatment will focus on managing the disease. If the cause is a medication, then the doctor may switch to a different medication or adjust the dosage.

Conclusion

A high RDW CV is a condition characterized by an increased variation in the size of RBCs. There are many potential causes of a high RDW CV, and the treatment depends on the underlying cause. If you have a high RDW CV, your doctor will recommend a course of treatment that is right for you.
