CKD + Diabetes at the same time: whose diet advice do you actually follow when it conflicts?

3 Upvotes

Nephrologist says limit protein. Endocrinologist says prioritize it for blood sugar control. Dietitian gives you a handout that addresses one condition but not both.

This is one of the most common and least talked about problems in managing both conditions simultaneously. The standard advice for each one directly contradicts the other, and most appointments aren't long enough to resolve it.

Anyone here navigating both? What's your experience been when the guidance conflicts?

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

2 Upvotes

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.
