What are the risks of recurring high potassium?

Having too much potassium in your blood can lead to serious health issues, which is why it is important to keep your levels in balance over time.1

If your levels are too high, it can affect the way your heart muscles work, which may lead to irregular heart rhythms (also known as arrythmia). In the worst case, this can cause a heart attack, leading to hospitalization or even death.2 

High potassium (hyperkalemia) can also increase the levels of a hormone called aldosterone.3 Increased aldosterone may have adverse (negative) effects on your brain, kidneys, blood vessels, and heart.4,5 

If you have chronic kidney disease (CKD), your high potassium can increase the risk of developing the last stage of kidney disease, otherwise known as end-stage renal disease (ESRD). This may need to be treated and/or managed with dialysis.6

If you need dialysis, this will usually involve your blood being cleaned by a machine. This typically takes 3-5 hours at a time and may need to be done 3-6 days a week.

Depending on your circumstances, dialysis may be carried out at home, or in a hospital or specialized treatment centre.7

What are the risks of stopping medications that cause high potassium?

Your high potassium may be a side effect of the medication you are taking. 

One option your doctor may consider is to reduce or completely stop the dose.

As some of these treatments are crucial for protecting your heart and kidneys, stopping or reducing the dose could worsen your overall condition and prognosis.

This can lead to an ongoing cycle where your different medications are regularly adjusted because of their effects on your other conditions, as shown below.8
