Diabetics typically lose their sensitivity to insulin. This means that their body cells are less responsive in their reaction to insulin and does not effectively absorb sugar from the bloodstream as a normal healthy body would, which ultimately leads to an increase in both blood sugar and higher blood insulin levels.
