Potassium High Level

Potassium supplements should therefore not be taken without the advise of your doctor. If you feel weakness and numbness, it may be due to high level of potassium and you should consult your doctor.

The symptoms of high level of potassium are irregular and/or rapid heart beat, low blood pressure, kidney disease, infrequent menstrual cycles, muscle spasms or cramps, joint / back pains, higher risk of cancer, bladder infections, poor immune system, anxiety, insomnia, irritability, impotence.
