What is hyperkalemia?

Hyperkalemia is too much potassium in the bloodstream. Potassium helps with basic metabolic functions such as breathing, digestion, body temperature and brain function. Normally, your kidneys remove any extra potassium, but if the kidneys aren't working properly hyperkalemia can occur. Tissue injuries such as burns, surgery, tumors or traumatic injury cause your cells to release potassium which can lead to a buildup. Some medications that affect kidney function, such as amiloride or potassium supplements, can also cause hyperkalemia.
