Your Care Instructions
Polycythemia (say "paw-lee-sy-THEE-mee-uh) is an abnormal increase in red blood cells. Some people also have an increase in their white blood cells and platelets. The extra red blood cells make your blood thicker than normal. This may raise your risk for blood clots that can cause heart attacks or strokes. Clots can form in the deep veins of the body, a condition called deep vein thrombosis. Or a clot can travel through the blood to a lung (a pulmonary embolism).
Polycythemia is sometimes caused by other conditions, such as chronic lung disease or other problems that decrease the oxygen supply to the tissues in the body (hypoxia). This is called secondary polycythemia.
Treatment depends on the cause of polycythemia. Your doctor may treat you by taking out some of your blood (phlebotomy). The process is like donating blood. Your doctor may even recommend that you donate blood. Treatment may also include taking medicines or having therapy to increase oxygen to the body.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
- Be safe with medicines. If your doctor recommends aspirin or other medicines, take them exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
- Follow your doctor's instructions if you have blood removed as part of your treatment. You will probably be advised to:
- Drink plenty of fluids before and after you have blood removed. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
- Take it easy after you have had blood removed. Do not do vigorous exercise.
- If you smoke, try to quit or cut back as much as you can. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
- Ask your doctor if you can take an antihistamine to help calm the itching. Some people who have this condition have itching.
- Wear medical alert jewelry that lists your clotting problem. You can buy this at most drugstores.
