Before major surgery, a client with type 1 diabetes has insulin requirements that are elevated but well controlled. What would you anticipate postoperatively?

Before major surgery, a client with type 1 diabetes has insulin requirements that are elevated but well controlled. What would you anticipate postoperatively?

• A. Decreased insulin requirements
• B. Fluctuating insulin requirements
• C. Increased insulin requirements sharply
• D. Insulin requirements remain elevated

Answer: (D)

Surgical stress triggers a release of hormones like cortisol, epinephrine, and growth hormone, plus inflammatory mediators. These substances raise blood glucose by increasing hepatic glucose production and creating insulin resistance. In a person with type 1 diabetes, endogenous insulin is minimal, so exogenous insulin must rise to counteract this stress-driven hyperglycemia. That’s why insulin requirements stay elevated in the immediate postoperative period, even if preoperative control was good. While exact levels can fluctuate with factors like anesthesia recovery, pain, and nutritional intake, the typical pattern is that needs remain higher than before surgery rather than dropping back to baseline. A sharply increased spike is possible in some cases, but the general expectation is a sustained elevation as the body stays in a stressed, catabolic state until healing progresses and normal function returns. This is why close glucose monitoring and appropriate insulin adjustment are essential after major surgery.
