Individuals with diabetes are unable to use glucose for fuel. In an attempt to compensate, the body switches over to metabolizing fat — partially or completely — as a fuel source. This requires the body to use more energy, leaving the individual fatigued.

Note that fatigue can also be an indicator of other serious medical problems. Contact your physician for more information.
