Your Care Instructions
Anemia is a low level of red blood cells, which carry oxygen throughout your body. Many things can cause anemia. Lack of iron is one of the most common causes. Your body needs iron to make hemoglobin, a substance in red blood cells that carries oxygen from the lungs to your body's cells. Without enough iron, the body produces fewer and smaller red blood cells. As a result, your body's cells do not get enough oxygen, and you feel tired and weak. And you may have trouble concentrating.
Bleeding is the most common cause of a lack of iron. You may have heavy menstrual bleeding or bleeding caused by conditions such as ulcers, hemorrhoids, or cancer. Regular use of aspirin or other anti-inflammatory medicines (such as ibuprofen) also can cause bleeding in some people. A lack of iron in your diet also can cause anemia, especially at times when the body needs more iron, such as during pregnancy, infancy, and the teen years.
Your doctor may have prescribed iron pills. It may take several months of treatment for your iron levels to return to normal. Your doctor also may suggest that you eat foods that are rich in iron, such as meat and beans.
There are many other causes of anemia. It is not always due to a lack of iron. Finding the specific cause of your anemia will help your doctor find the right treatment for you.
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?
- Take your medicines exactly as prescribed. Call your doctor if you think you are having a problem with your medicine.
- If your doctor recommends iron pills, take them as directed:
- Try to take the pills on an empty stomach about 1 hour before or 2 hours after meals. But you may need to take iron with food to avoid an upset stomach.
- Do not take antacids or drink milk or caffeine drinks (such as coffee, tea, or cola) at the same time or within 2 hours of the time that you take your iron. They can make it hard for your body to absorb the iron.
- Vitamin C (from food or supplements) helps your body absorb iron. Try taking iron pills with a glass of orange juice or some other food that is high in vitamin C, such as citrus fruits.
- Iron pills may cause stomach problems, such as heartburn, nausea, diarrhea, constipation, and cramps. Be sure to drink plenty of fluids, and include fruits, vegetables, and fiber in your diet each day. Iron pills often make your bowel movements dark or green.
- If you forget to take an iron pill, do not take a double dose of iron the next time you take a pill.
- Keep iron pills out of the reach of small children. An overdose of iron can be very dangerous.
- Follow your doctor's advice about eating iron-rich foods. These include red meat, shellfish, poultry, eggs, beans, raisins, whole-grain bread, and leafy green vegetables.
- Steam vegetables to help them keep their iron content.
