blood sugar spike
Rapid glycemic rise
A blood sugar spike is a rapid rise in blood glucose levels, typically after eating foods high in sugar or refined carbohydrates.
The body responds by releasing insulin to bring levels back down, but the sharp climb can cause symptoms like fatigue, irritability, or brain fog: I crashed hard after that blood sugar spike from the donuts.
People with diabetes monitor closely to avoid these swings.
