Fatigue is defined as an unusual tiredness that interferes with normal activities and is not relieved by resting or a good night’s sleep. Fatigue may be more severe in patients with MDS who also have anemia. Insomnia (difficulty sleeping) is common in older adults and may contribute to fatigue. Other things that can contribute to fatigue include: inactivity, pain, emotional distress, poor nutrition, and other illnesses that are not well controlled such as diabetes or thyroid disorders.
