Grapefruit sounds harmless, even refreshing, but Dr Yaranov cautions that it can change how the liver processes medicines.
After heart surgery or transplant, patients rely on drugs that must stay within a safe range in the body. Grapefruit can cause those levels to spike dangerously high, leading to toxic side effects or organ rejection.
It’s not about the fruit itself, but about how it disrupts the body’s ability to balance critical medication levels.
