RDW

What This Marker Means

RDW measures how varied your red blood cells are in size. High RDW indicates mixed nutrient deficiencies or recent changes in bone marrow function. It's often elevated early in anemia.

How Alcohol Affects This Marker

Alcohol affects bone marrow and nutrient absorption, commonly leading to increased RDW. Fluctuations in drinking patterns can also shift RDW over time.

How to Discuss With Your Doctor

Ask whether your RDW suggests combined deficiencies or early anemia. If high, discuss evaluating B12, folate, thiamine, and iron.
