4 yr. old child. I am tired of being tired.
Fatigue can certainly result from de-conditioning.
You mention being overweight and recently spending 6 months in a wheelchair. Being out of shape can contribute to your fatigue problem. It was certainly a good idea to be checked for anemia and hormonal imbalances, as these are common causes of fatigue. Other common causes include depression and lack of adequate rest. I would suggest you begin a regular exercise program and review the adequacy of your diet.
