Potassium is a mineral in many foods. It is sometimes shown as its symbol, the letter K.
Potassium:
- Balances fluid in your body
- Helps your muscles work
- Affects your heartbeat
Healthy kidneys help keep potassium in balance. When your kidneys are not working well, your potassium level may be too low or too high. Many people with kidney disease have potassium levels that are too high.
Too much potassium can cause:
- Cramps
- Weak muscles
- Irregular heart beat
- Heart attack
