It is important to note that you could be having a heart attack without feeling discomfort in your chest, as is common in women. A sudden feeling of fatigue for no reason could be a sign that a heart attack is incoming. The heart has to work harder as arteries begin to close, and can make simple tasks feel exhausting. This can result sleeping longer hours at night or feeling like you need to take multiple naps during the day.
Polycythemia is an increased number of red blood cells in the blood. In polycythemia, the levels of hemoglobin (Hgb), hematocrit (Hct), or the red blood cell (RBC) count may be elevated when measured in the complete blood count (CBC), as compared to normal. Hemoglobin levels greater than 16.5 g/dL (grams per deciliter) in women and greater than 18.5 g/dL in men suggest polycythemia.
From Wikipedia, the free encyclopedia. Polycythemia (or Polycythaemia, see spelling differences) vera (PV, PCV) (also known as erythremia, primary polycythemia and polycythemia rubra vera) is a neoplasm in which the bone marrow makes too many red blood cells. It may also result in the overproduction of white blood cells and platelets. Most of the health concerns associated with polycythemia vera are caused by the blood being thicker as a result of the increased red blood cells. It is more common in the elderly and may be symptomatic or asymptomatic. Common signs and symptoms include itching (pruritus), and severe burning pain in the hands or feet that is usually accompanied by a reddish or bluish coloration of the skin. Patients with polycythemia vera are more likely to have gouty arthritis.
