About Hematocrit
Percentage of blood volume occupied by red blood cells.
The reasons for low HCT
Low hematocrit is often associated with anemia, blood loss, chronic kidney disease, or nutritional deficiencies. Consuming a diet rich in iron, folate, and vitamin B12, staying hydrated, and treating underlying conditions like kidney disease can help increase levels.
The reasons for elevated HCT
High hematocrit can be caused by dehydration, smoking, lung disease, or polycythemia vera. Ensuring proper hydration, avoiding tobacco, and treating underlying lung or heart conditions can help lower levels.
Is it bad too have too high/low HCT?
Low hematocrit reduces oxygen transport in the blood, leading to chronic fatigue, dizziness, and shortness of breath. If left untreated, it may result in cardiovascular strain and decreased immune response.
High hematocrit increases blood viscosity, raising the risk of clotting, stroke, and heart attack. It can also cause headaches, dizziness, and impaired circulation.
