Introduction
When you receive your blood test report, you might come across a term called RDW (Red Cell Distribution Width). If your RDW levels are high, it’s natural to feel concerned. But don’t worry, this article will help you understand what it means, why it happens, and what you can do about it.
What is RDW?
RDW stands for Red Cell Distribution Width, a measure of the variation in the size of your red blood cells (RBCs). Normally, red blood cells are fairly uniform in size. A high RDW means there’s a greater difference in size between your smallest and largest red blood cells.
Why Does RDW Matter?
Red blood cells carry oxygen throughout your body. If their sizes vary too much, it could indicate an underlying health issue. A high RDW doesn’t diagnose a specific condition but helps doctors identify possible problems that need further testing.
Common Causes of High RDW
Several conditions can lead to high RDW levels, including:
1. Nutritional Deficiencies
- Iron Deficiency Anaemia: Low iron levels affect red blood cell production, leading to uneven sizes.
- Vitamin B12 or Folate Deficiency: These vitamins are essential for healthy RBC production.
2. Chronic Diseases
- Liver disease, kidney disease, or inflammatory conditions can impact red blood cell formation.
3. Blood Disorders
- Conditions like thalassemia or sickle cell anaemia can cause abnormal RBC sizes.
4. Recent Blood Loss or Transfusion
- Sudden blood loss or a transfusion can temporarily alter RDW levels.
5. Infections or Chronic Inflammation
- Long-term infections or autoimmune diseases may affect RBC production.
Symptoms to Watch For
Since high RDW is often linked to anaemia or other conditions, you may experience:
- Fatigue or weakness
- Pale skin
- Shortness of breath
- Dizziness
- Irregular heartbeat
If you notice these symptoms, consult a doctor for further evaluation.
How to Manage High RDW
1. Improve Your Diet
- Iron-rich foods: Spinach, lentils, red meat, and fortified cereals.
- Vitamin B12 sources: Eggs, dairy, fish, and fortified plant-based milk.
- Folate-rich foods: Leafy greens, beans, and citrus fruits.

3. Manage Underlying Conditions
If you have diabetes, kidney disease, or inflammation, follow your doctor’s treatment plan.
4. Avoid Alcohol & Smoking

5. Regular Blood Tests
Monitor your RDW and other blood parameters to track improvements.
