When you take steroid-induced hyperglycemia, a rise in blood sugar caused by corticosteroid medications. It's not diabetes, but it acts like it—until the steroids stop. This isn’t rare. People on prednisone for asthma, rheumatoid arthritis, or even after an organ transplant often see their blood sugar climb. And if you already have prediabetes or a family history of type 2 diabetes, the risk jumps even higher.
