Dr. Jaiwant Rangi explains the legacy effect: years of high blood sugar damage blood vessels, nerves, and organs in ways that persist even after glucose improves. Early detection and treatment matter because this cellular damage cannot be fully reversed later.

The legacy effect is something very important that we must talk to patients earlier on in the disease. The damage caused by years of uncontrolled blood sugar does not immediately disappear just because your blood sugars have improved later. Think of it like water damage in the house. You know, you can fix the leak. That is important. But the damage that happened while the water was running, the wet floors, the moistness inside the walls, the weakened foundation, and the damage may already be there. The body remembers. The blood vessels remember, the nerves remember, the kidney remembers, the eyes remember, the heart remembers. This is why timing matters so much.
