  Hyperkalemia: Symptoms and Treatments If you have hyperkalemia, you have too much potassium in your   blood. The body needs a delicate balance of potassium to help the heart and other muscles work properly. But too much  potassium in your blood can lead to dangerous, and possibly deadly, changes in heart rhythm. Causes of Hyperkalemia Hyperkalemia -- high potassium in your blood -- may occur if your  kidneys do not work properly and cannot remove potassium from your body or if your body's cells release too much potassium. Kidney disease is the most common cause of hyperkalemia. Your kidneys help control the  balance of potassium in your body. If they do not work properly, they cannot filter extra  potassium from the blood or remove it from the body. A hormone called aldosterone tells the kidneys when to remove potassium -- as well as sodium. Diseases that decrease the production of this hormone, such as Addison's disease, can lead to hyperkalemia. Excess potassium in the diet can also contribute to increased levels in your blood, especially if there is an issue with kidney function. Salt substitutes typically contain high amounts of  potassium. Foods such as melons, orange juice, and bananas are rich in potassium too. Some health problems interfere with how potassium moves out of the body's cells. Sometimes, cells release too much potassium. Releasing too much potassium can result from:    Breakdown of red blood cells, called hemolysis    Breakdown of muscle tissue, called rhabdomyolysis    Burns, trauma, or other tissue injury    Uncontrolled diabetes Conditions that can affect the kidney's ability to remove potassium from the body include:    Hormonal disorders    Lupus    Kidney failure    Other kidney diseases Drug-Induced Hyperkalemia Certain medications can also make it harder for the kidneys to remove potassium. This is  particularly true if you have kidney disease or problems with the way your body handles  potassium. Also, some drugs may increase the amount of potassium in the body. Medications that have been linked to hyperkalemia include:     Antibiotics, including  penicillin G and trimethoprim.     Azole antifungals, used to treat vaginal yeast infections and other fungal infections.    Blood pressure drugs called angiotensin-converting enzyme (ACE) inhibitors.    Blood pressure drugs called angiotensin-receptor blockers (ARBs), although they are less likely than ACE inhibitors to increase potassium levels.    Blood pressure drugs called beta-blockers.    Herbal supplements, including milkweed, lily of the valley, Siberian ginseng, Hawthorn  berries, or preparations from dried toad skin (Bufo, Chan Su, Senso).    Heparin, a blood thinner.     Nonsteroidal anti-inflammatory medications ( NSAIDs).    Potassium supplements.    Potassium-sparing diuretics, including triamterene, amiloride (Midamor ), and spironolactone (Aldactone). Symptoms of Hyperkalemia Too much potassium in your blood can affect how your heart works. Symptoms of hyperkalemia can include:    Abnormal heart rhythm -- arrhythmia -- that can be life-threatening    Slow heart rate    Weakness Diagnosing Hyperkalemia Hyperkalemia can be difficult to diagnose. The symptoms can be mild and may be due to many different health problems.
