Understanding their distinct roles reveals how the body transitions between states of nourishment and fasting, a balance critical for long-term health. After a meal, carbohydrates are broken down into glucose, causing blood sugar levels to rise.
Insulin and Glucagon Hormones in the Fasting State
A diet high in refined sugars can force the pancreas to perpetually secrete insulin, potentially leading to insulin resistance over time. This hormone ensures that the brain and red blood cells, which rely solely on glucose, remain energized even during fasting states.
Glucagon: The Catabolic Guardian In contrast, glucagon is secreted by the alpha cells of the pancreas when blood sugar levels dip, such as during exercise or between meals. Interplay and Clinical Significance The relationship between insulin and glucagon is a perfect example of endocrine homeostasis.
