Correct. In Type 1 diabetes, not only does the pancreas stop producing insulin (Beta cell destruction), but another issue often arises — glucagon dysfunction -which is made from Alpha cells.
Glucagon is a hormone that normally signals the liver to release stored glucose (Back up reserve) into the bloodstream. This process is crucial for raising our blood sugar levels during periods when we haven't eaten, such as overnight or between meals (fasting). HOWEVER IN TYPE 1 THIS CAN BE LOST / DIMINISHED.
If glucagon function is disrupted, the body may struggle to raise blood sugar to safe levels on its own. This is critical for times in-between meals and overnight, increasing the risk of hypoglycemia (low blood sugar). Most people without diabetes don't face this challenge because of their “normal” glucagon function.
It’s why you have to be extra careful and vigilant when skipping meals!
