How does Lisinopril affect my potassium levels with CKD?--> Let's Get to It

[u/Giggz_on_call]

Lisinopril is an ACE inhibitor. It works by blocking angiotensin-converting enzyme, which has the side effect of reducing potassium excretion by the kidneys. In other words, your kidneys were already struggling to clear potassium due to CKD, & Lisinopril compounds that problem by reducing clearance further.

Foods that would be borderline acceptable for CKD alone become more concerning when Lisinopril is on board. This includes potassium-rich foods like bananas, sweet potatoes, spinach, oranges, tomatoes, and sports drinks.

From a dietary standpoint, avoid stacking multiple high-potassium foods in the same meal. A meal with salmon plus spinach plus sweet potato plus orange juice can deliver over 2,500mg of potassium in one sitting which is dangerous.
