A member asked:

Should u eat or drink b4 taking a follow up potassium test, with kidney not functioning so well?

A doctor has provided 1 answer

Ok to eat or drink: A blood test to measure the potassium level is usually not a "fasting" test, so eating or drinking is ok to do, unless one's doctor says otherwise.

How much potassium can you eat at once and not develop hyperkalemia if you're taking angiotensin receptor blockers and have normal kidney function. For example eating a cup of yogurt with two bananas and some nuts is about 1000mg of potassium?
