About Mean Corpuscular Hemoglobin
MCH measures the average amount of hemoglobin in red blood cells.
The reasons for low MCH
Low MCH is usually due to iron deficiency anemia or thalassemia, leading to smaller, pale red blood cells. To increase MCH, consuming iron-rich foods and supplements, and treating underlying causes is necessary.
The reasons for elevated MCH
High MCH is often linked to macrocytic anemia caused by vitamin B12 or folate deficiency, liver disease, or alcohol abuse. Increasing B12 and folate intake, reducing alcohol, and addressing liver conditions can help normalize MCH.
Is it bad too have too high/low MCH?
Low MCH can reduce the oxygen-carrying capacity of blood, leading to fatigue, weakness, and poor concentration. Severe deficiency can impair organ function and energy levels.
High MCH can cause neurological issues and cardiovascular strain, especially if linked to B12 or folate deficiencies. Long-term high MCH can contribute to anemia-related complications.
