Haemoglobin is the protein in red blood cells responsible for carrying oxygen throughout the body, but elevated levels cause blood to thicken, slowing circulation and increasing health risks.

Common causes of high haemoglobin include living at high altitudes, chronic smoking, dehydration, and conditions like chronic obstructive pulmonary disease (COPD).

In more severe cases, high haemoglobin can be linked to bone marrow disorders, such as polycythemia vera, a rare condition that causes the body to produce too many red blood cells.

High haemoglobin levels increase the risk of blood clots, which can lead to heart attacks, strokes, or deep vein thrombosis, as well as hypertension due to thicker blood.

Symptoms like fatigue and dizziness may still occur despite the high oxygen-carrying capacity, due to poor circulation.

Treatment typically involves addressing the root cause and may include therapeutic phlebotomy (removing blood) or medications to reduce red blood cell production and clotting risks.

Preventive measures include staying hydrated, maintaining a balanced diet, regular exercise, stress management, and avoiding smoking and alcohol.
