Hemoglobin
What is HGB in blood tests?
HGB Measurement
Low: Below 13.8g/dL
High: Above 17.2g/dL
About Hemoglobin
Protein in red blood cells that carries oxygen.
The reasons for low HGB
Low hemoglobin is usually caused by anemia, blood loss, nutritional deficiencies (iron, vitamin B12, folate), kidney disease, or chronic illnesses. To increase hemoglobin, consuming more iron-rich foods, vitamin C (to enhance iron absorption), and folate-rich foods, and treating any underlying medical conditions is crucial.
The reasons for elevated HGB
High hemoglobin levels can be due to dehydration, high altitude exposure, smoking, lung disease, or polycythemia vera. Hydration, smoking cessation, and medical treatment (such as blood donation for polycythemia) can help lower levels.
Is it bad too have too high/low HGB?
Low hemoglobin reduces oxygen-carrying capacity, causing fatigue, weakness, shortness of breath, and increased risk of heart problems. Prolonged anemia can lead to organ dysfunction and severe complications in chronic conditions.
High hemoglobin thickens the blood, increasing the risk of blood clots, stroke, and heart failure. Severe cases may require medical intervention, such as bloodletting or medication to reduce blood viscosity.
