CSII Safety: Understanding Continuous Infusion Insulin Therapy Risks and Management

When you use CSII, Continuous Infusion Insulin Therapy, a method of delivering insulin through a wearable pump that mimics the body’s natural insulin release. Also known as insulin pump therapy, it gives tighter blood sugar control than injections—but only if used safely. Thousands of people rely on CSII daily, but safety isn’t automatic. A pump malfunction, a dislodged catheter, or even a missed bolus can send blood sugar soaring—or crash it dangerously low. The biggest threat? Silent hypoglycemia. Unlike injections, where you feel the delay, CSII delivers insulin constantly. If the flow stops, your body keeps using glucose without replacement—and you might not notice until it’s too late.

That’s why insulin pump safety, the set of practices and safeguards designed to prevent errors, malfunctions, and life-threatening complications in CSII users isn’t optional. It’s routine. You need to check your pump site every day. Look for redness, swelling, or leakage. Test your blood sugar more often when you’re sick, stressed, or changing your routine. And never skip your basal rate check—even if you feel fine. A small drop in insulin delivery over hours can build into a crisis. hypoglycemia prevention, the proactive steps taken to avoid dangerously low blood sugar in insulin users, especially those on continuous delivery systems means having fast-acting carbs nearby at all times, setting low glucose alerts on your pump, and teaching family members how to respond. Even something as simple as keeping a spare pump battery in your bag can save your day.

CSII safety also means knowing when something’s wrong. If your pump alarms repeatedly, your blood sugar stays high despite boluses, or you feel off without explanation—don’t ignore it. A blocked catheter or air bubble can look like insulin resistance. Many people assume their pump is working because it’s beeping, but that’s not enough. You need to verify. That’s why the best users don’t just trust the device—they test, track, and double-check. And when in doubt, switch to injections. Temporary. Just until you’re sure.

There’s no magic fix for CSII safety. It’s daily habits. It’s knowing your numbers. It’s asking questions when something doesn’t feel right. Below, you’ll find real-world stories and expert guidance on avoiding the most common—and dangerous—mistakes. From pump site infections to overnight lows, these posts give you the tools to use your therapy without fear.
