Why does hyperglycemia make one feel hungry?
Hypo, of course, makes you hungry because your blood sugar is low. Hyper makes you hungry even though your blood sugar is high because your cells are not getting any of it (so there is no fuel for energy) and send signals to the brain that they are ‘hungry’, so you eat, blood sugar rises, cells still can’t get any, send signal, you eat … medication and exercise help the cells get their food (blood sugar), so as blood sugar is reduced, so are those erroneous hunger signals both high and low sugar cause mental confussion because your brain cells are not getting their fuel (sugar) and begin to conserve their resources (begin functioning at a reduced rate or by eliminating less critical areas). If the condition persists long enough, brain cells starve and die (this is why diabetic coma can lead to permanent damage and sometimes death of the person).
