Differential Diagnosis for Generalized Fatigue in a 60-year-old

Single Most Likely Diagnosis

Other Likely Diagnoses

  • Hypothyroidism: A condition where the thyroid gland doesn't produce enough thyroid hormones, leading to fatigue, among other symptoms.
  • Diabetes Mellitus: Uncontrolled diabetes can cause fatigue due to high blood sugar levels, dehydration, and electrolyte imbalances.

  • Sleep Apnea: A sleep disorder that can cause fatigue due to poor sleep quality.
  • Depression: A mental health condition that can cause fatigue, among other symptoms.

Do Not Miss Diagnoses

  • Heart Failure: A condition where the heart is unable to pump enough blood, leading to fatigue, among other symptoms. Missing this diagnosis can be fatal.
  • Chronic Obstructive Pulmonary Disease (COPD): A lung disease that can cause fatigue due to poor oxygenation.
  • Lymphoma: A type of cancer that can cause fatigue, among other symptoms. Early detection is crucial for treatment.
  • Adrenal Insufficiency: A condition where the adrenal glands don't produce enough hormones, leading to fatigue, among other symptoms.

Rare Diagnoses

  • Addison's Disease: A rare condition where the adrenal glands don't produce enough hormones, leading to fatigue, among other symptoms.
  • Pernicious Anemia: A rare condition where the body is unable to absorb vitamin B12, leading to fatigue, among other symptoms.
