3. Increased appetite and hunger
When you have an increased appetite, the phenomenon is also called hyperphagia or polyphagia. When it is one of the prediabetes signs this increased hunger happens because you have chronically high blood sugar.
But why does high blood sugar make you feel more tired than usual? When the levels of your blood sugar remain high, the insulin receptors are not working properly. This makes glucose unable to enter the cells to be later used as energy.
And from here, things are easier to explain. When you don’t have energy, you will feel more hungry because food is the main source of energy for the human body.
