High Potassium in Urine: Causes, Risks & Kidney Health

Kidneys normally filter and excrete any excess potassium in urine, thus maintaining proper potassium levels. Dangerously high potassium levels can exist if the urinary process is not functioning properly.

Identification

• Potassium is both an electrolyte and a mineral. It helps keep the amount of fluid inside and outside the body's cells and the electrolyte balance of the body. Potassium also plays an important role in how nerves and muscles work.

Kidney Problems

• When the urinary process is faulty, a condition known as hyperkalemia, or hyperpotassemia (high potassium level), may occur. If not treated promptly, this can lead to sudden death from irregular heatbeats (arrhythmia).

Foods to Avoid

• A high consumption of potassium salt substitutes is detrimental. Consuming too many high-potassium foods such as avocados, apricots, bananas, dates, nectarines, oranges, raisins, artichokes, parsnips, spinach, tomatoes, yams, whole grains, molasses, clams, cod, halibut, yogurt and nuts elevates potassium levels. Consuming too many potassium supplements is discouraged.

Potassium Elevators

• Some diuretics can retain potassium in the body, leading to hyperkalemia. Fluctuating hormone levels and some cancer treatments can also elevate potassium levels.

Symptoms

• Symptoms of high potassium levels include muscle cramps or weakness, nausea, diarrhea, frequent urination, dehydration, low blood pressure, confusion, irritability, paralysis and changes in heart rhythm. Talk to your health professional about any concerns you have regarding the need for testing your potassium levels if these symptoms arise.
