physiology — see what changes in the body, and when

Digestive processes start breaking carbohydrate into absorbable sugars.

Glucose appearance from the gut contributes to a rising post-meal range in the bloodstream.

Rising glucose usually prompts pancreatic beta cells to increase insulin secretion.

As glucose appearance slows and uptake continues, the representative ranges move back toward their starting state.

Insulin supports glucose uptake in tissues such as skeletal muscle and helps the liver shift toward storage and use.
