About Mean Corpuscular Volume
MCV measures the average size of red blood cells.
The reasons for low MCV
Low MCV (microcytosis) is associated with iron deficiency anemia, chronic disease anemia, and thalassemia. To increase MCV, iron supplementation, addressing inflammation, and ensuring sufficient vitamin B12 and folate levels is recommended.
The reasons for elevated MCV
High MCV (macrocytosis) is commonly due to vitamin B12 or folate deficiency, liver disease, alcoholism, or bone marrow disorders. Increasing dietary B12 and folate, reducing alcohol intake, and addressing underlying conditions can help normalize MCV.
Is it bad too have too high/low MCV?
Low MCV leads to small, inefficient red blood cells, reducing oxygen transport and causing fatigue, dizziness, and weakness. Severe cases may lead to organ dysfunction over time.
High MCV can result in abnormal red blood cell production, leading to neurological symptoms, fatigue, and increased cardiovascular risks. Severe cases may require medical intervention to prevent complications.
