What happen when the level of RBC is increase?

When the level of red blood cells (RBCs) increases, a condition known as polycythemia occurs. This can lead to thicker blood, increasing the risk of blood clots, stroke, and heart complications due to reduced blood flow. Elevated RBC levels can be caused by various factors, including dehydration, smoking, or living at high altitudes. It's essential to identify the underlying cause to manage and treat the condition effectively.
