The details of how you feel help guide your caregiver in finding out what is causing the fatigue. You will be asked about your present and past health condition. It is important to review all medicines that you take, including prescription and non-prescription items. A thorough exam will be done. You will be questioned about your feelings, habits, and normal lifestyle. Your caregiver may suggest blood tests, urine tests, or other tests to look for common medical causes of fatigue.
