MCV

The average size of your red blood cells.

If it's high

Larger cells can be linked to low B12 or folate, alcohol, or thyroid issues.

• B12: milk, curd, paneer, eggs, fish, chicken; fortified cereals if vegetarian
• Folate: leafy greens, dals, chickpeas, oranges

If it's low

Smaller cells are often linked to low iron or inherited conditions such as thalassaemia trait.

• Iron-rich foods: spinach and other greens, lentils, rajma, chana, soya, eggs, fish or lean meat
• Vitamin C with meals (amla, guava, orange, lemon) to help absorb iron

A question for your doctor

Would iron studies or B12 testing help explain this?
