About Red Blood Cell Count
Measures the number of red blood cells, important for oxygen transport.
The reasons for low RBC
A low RBC count (anemia) can result from various conditions, including iron deficiency, chronic illness, kidney disease, bone marrow suppression, or blood loss. To increase RBC levels, consuming iron-rich foods (such as red meat, lentils, and spinach), increasing vitamin B12 and folate intake, staying well-hydrated, and addressing underlying medical conditions such as kidney disease or chronic inflammation is essential.
The reasons for elevated RBC
A high RBC count (polycythemia) can occur due to dehydration, lung disease, heart disease, or living at high altitudes. To lower RBC levels, ensuring proper hydration, treating underlying conditions (such as sleep apnea or lung disease), and reducing exposure to high altitudes can help.
Is it bad too have too high/low RBC?
Chronic low RBC levels reduce oxygen transport, leading to fatigue, dizziness, pale skin, and shortness of breath. Severe cases may result in cardiovascular stress and decreased immune function, making individuals more prone to illness.
Elevated RBC levels can thicken the blood, increasing the risk of clotting, stroke, and heart attack. If untreated, it may also cause dizziness, headaches, and high blood pressure, putting a strain on the heart.
