Questions to Ask Your Doctor or Nurse
Question: What is my sodium limit per day?
Reason for asking this question: Most people with heart failure should limit their sodium intake, even if they do not have symptoms. Following a low-sodium diet will help prevent fluid from building up in your body and may even decrease your need for some medications.
Your doctor or nurse is the best person to tell you exactly how much sodium you can eat each day, but they may forget to discuss this important aspect of your care. So ask them about your sodium limit.
Question: I hear a lot about sodium, but what about potassium? Should I be on a diet that is high or low in potassium?
Reason for asking this question: Your body needs potassium to work properly, so it is important that you have the right amount in your blood.
Some heart failure medicines can cause potassium levels to go either up or down. For example:- Water pills may cause a drop in potassium.
- Angiotensin-converting enzyme (ACE) inhibitor and spironolactone pills may cause an increase in potassium. (See Module 3: Heart Failure Medicines for definitions and more information).
Your doctor or nurse should check your blood potassium level and tell you if you need to do anything special to keep your potassium level normal.
If you have low potassium, your doctor or nurse may advise you to eat foods high in potassium. They may also prescribe a potassium pill to make sure you are getting enough potassium. If your doctor or nurse suggests that you eat foods high in potassium, try the following:
| Avocados | Potatoes and sweet potatoes | Bananas | Spinach | Broccoli | Strawberries | Cantaloupe | Tomatoes | Dried fruits (prunes, dates, raisins) | Whole grains | Nuts | Winter squash | Oranges and other citrus fruits |
But if your potassium level is high, your doctor or nurse may advise you to avoid eating certain foods and salt substitutes containing potassium. Always check with your doctor or nurse before using salt substitutes that contain potassium.
