This tool helps you think through whether your symptoms warrant contacting a doctor or seeking urgent care — it does not diagnose hyperkalemia (high potassium) and cannot replace a blood test or a clinician’s judgment. If you have any doubt, contact a healthcare provider rather than relying on this checklist.

Important: this is a general educational screening aid, not a diagnostic tool, and it does not know your medical history, lab values, or medications beyond what you check above. If you are experiencing severe symptoms — especially an irregular heartbeat, chest pain, or severe weakness — seek emergency care immediately regardless of what this tool shows.

What causes hyperkalemia and who’s at risk
Hyperkalemia (high blood potassium) most often develops in people with kidney disease, heart failure, or diabetes, or in those taking medications that raise potassium levels — including ACE inhibitors, ARBs, and potassium-sparing diuretics like spironolactone. Because potassium plays a critical role in heart rhythm, both very high and very low levels can affect cardiac function, which is why heart-related symptoms are treated as the most urgent warning sign.

Frequently asked questions
What foods are highest in potassium?
Bananas are the most commonly cited example, but potatoes, oranges, spinach, avocados, and dairy products often contain more potassium per serving. If you’ve been told to watch your potassium intake, ask your doctor or a renal dietitian for a full list rather than avoiding just one or two foods.
Can hyperkalemia happen without any symptoms?
Yes — hyperkalemia is often asymptomatic, especially at mild-to-moderate levels, and may only be caught through a routine blood test. This is one reason regular monitoring matters for people at higher risk, such as those with kidney disease or on RAAS-inhibitor medications.
Should I stop my blood pressure or heart medication if I have high potassium?
Never stop a prescribed medication on your own based on a symptom checker or general article. Many of the medications linked to hyperkalemia are also protecting your kidneys or heart, so the right approach — continuing, adjusting the dose, or adding a potassium binder — depends on your specific situation and should be decided with your prescriber.
