Are high hemoglobin levels dangerous?
Sometimes high hemoglobin levels are dangerous. Usually levels of hemoglobin that are above normal indicate a problem with your health. The levels are usually high when a patient has advanced lung cancer such as emphysema, certain types of tumors, disorders of the bone marrow, and abuse of epogen by athletes for blood doping purposes. There are also times when the body produces false high’s. These times are when someone lives at high altitudes, or when someone is dehydrated, but the levels return to normal when the person goes to an area of normal altitudes or when the dehydrated persons fluids are replenished.
