Why RDW is Low

RDW is an abbreviation for red blood cell distribution width. It is a measure of the variation in the size of red blood cells. A low RDW means that the red blood cells are all very similar in size. This can be a sign of several different conditions, some of which are more serious than others.

Causes of Low RDW

There are a number of different conditions that can cause a low RDW. Some of the most common include:

Vitamin B12 deficiency

Vitamin B12 is an essential nutrient that is involved in the production of red blood cells. A deficiency of this nutrient can lead to a condition called megaloblastic anemia, which is characterized by the production of large, immature red blood cells. This can cause a low RDW.

Iron deficiency

Iron is another essential nutrient that is involved in the production of red blood cells. A deficiency of this nutrient can lead to a condition called iron deficiency anemia, which is characterized by the production of small, pale red blood cells. This can also cause a low RDW. In addition, a deficiency of folic acid will also lead to the same.

Liver disease

Liver disease can interfere with the production of red blood cells, which can lead to a low RDW. In addition, it can increase the destruction of red blood cells in addition to decreasing their production.

Kidney disease

Kidney disease can also interfere with the production of red blood cells, which can lead to a low RDW. This is because the kidneys also help to regulate the production of red blood cells.

Bone marrow disorders

Bone marrow disorders, such as leukemia and aplastic anemia, can also cause a low RDW. Because these disorders affect the bone marrow, it is unable to produce red blood cells effectively, causing low RDW.

Symptoms of Low RDW

A low RDW may not cause any symptoms. However, some people with a low RDW may experience symptoms such as fatigue, weakness, shortness of breath, and pale skin. These symptoms are caused by the underlying condition that is causing the low RDW. In most cases, low RDW is only noticed during blood tests and blood work.

Diagnosis of Low RDW

A low RDW is typically diagnosed with a blood test. This test measures the size and shape of red blood cells. A low RDW is diagnosed when the RDW is below the normal range. The normal range for RDW is typically between 11.5% and 14.5%. Consulting a doctor or healthcare provider is important if you have been diagnosed with low RDW.

Treatment for Low RDW

The treatment for a low RDW depends on the underlying cause. If the low RDW is caused by a vitamin B12 or iron deficiency, the treatment will involve taking supplements of these nutrients. If the low RDW is caused by liver or kidney disease, the treatment will focus on managing the underlying disease. If the low RDW is caused by a bone marrow disorder, the treatment will depend on the specific disorder.

Conclusion

A low RDW can be a sign of a number of different conditions. Some of these conditions are more serious than others. If you have a low RDW, it is important to see your doctor to determine the cause. Early diagnosis and treatment of the underlying cause can help to prevent serious complications.
