Why must individuals managing Chronic Kidney Disease (CKD) be cautious regarding high potassium squash intake?

Compromised kidneys may not filter potassium efficiently, leading to hyperkalemia.

For individuals whose kidneys are not functioning optimally due to Chronic Kidney Disease (CKD), managing mineral levels in the diet is critical. Squash varieties that are notably higher in potassium can become problematic because compromised kidney function impairs the body's ability to efficiently filter out this mineral. When potassium is not properly cleared, it can accumulate in the bloodstream, leading to a dangerous condition known as hyperkalemia. Elevated blood potassium levels pose a serious risk because they can negatively impact heart rhythm. Therefore, CKD patients must strictly manage or limit certain squash portions under the guidance of a renal dietitian or physician.
