Understanding Delayed Blood Glucose Spikes from Comfort Foods: Insights from an Insulin Pump User

Are you puzzled by unexpected blood glucose spikes hours after savoring your favorite comfort foods? You’re not alone. Many of us in the diabetes community face this challenge, especially when managing our condition with insulin pumps. In today’s post, I’ll explore the science behind these delayed spikes and share my personal journey using the Medtronic Minimed 780G Insulin Pump to effectively manage them.

The Science Behind Delayed Glucose Spikes


When we indulge in high-fat comfort foods, our bodies experience a slower digestion process. This delay often results in blood glucose levels spiking hours after eating, rather than immediately. For those of us relying on insulin pumps, understanding and anticipating this reaction is key to maintaining our blood sugar levels.

Personal Experience with Meatloaf and Potatoes

I experienced this firsthand with a meal of meatloaf and butter-rich potatoes. My insulin bolus at 7pm seemed to do the trick initially, but by 10pm, my blood sugar began to rise, peaking around midnight. Fortunately, my Medtronic Minimed 780G Insulin Pump’s auto-correction features kicked in, with auto basal adjustments visible in the graph below. This automated insulin delivery allowed me to sleep through the night peacefully, waking up to a near-perfect blood glucose level of 105 mg/dL in the morning.

Other Comfort Foods to Watch Out For

It’s not just meatloaf and potatoes. Foods like pizza, with its high carb and fat content, creamy pastas, and even fried foods, can also lead to similar delayed spikes in blood sugar. Learning how different foods affect your body is an essential part of diabetes management.

Tips for Insulin Pump Users


For those using insulin pumps, it’s important to monitor your blood sugar closely when eating these types of meals. You might need to adjust your pump settings or plan for a later insulin bolus. Understanding your body’s response to different foods can significantly improve your blood sugar management.
