Posted under IC22 Life Insurance Underwriting

Answer: (a).Polycythemia Explanation:The disorder of blood that is caused by an excess of red blood cells in the body is Polycythemia. In this disorder, the body makes too many red blood cells which makes the blood thicker than normal. This can cause blood clots to form more easily which can block blood flow through arteries and veins, leading to serious health problems like heart attack or stroke. Polycythemia can arise as a primary condition or as a compensatory mechanism to chronic oxygen lack. Primary Polycythemia is also known as Polycythemia vera (PV), which is caused by a mutation in the body's JAK2 gene. Secondary Polycythemia is caused by long-term exposure to low oxygen levels, and people who have severe heart or lung disease, smoke, spend long hours at high altitudes, or are exposed to high levels of carbon monoxide are at risk.
