Differential Diagnosis for Symptoms of Extreme Fatigue, Shaky Feeling, and Dizziness

Single Most Likely Diagnosis

  • Hypoglycemia: This condition, characterized by low blood sugar, can cause symptoms such as shakiness, dizziness, and fatigue. It is a common and easily treatable condition, making it a likely diagnosis for these symptoms.

Other Likely Diagnoses

  • Anemia: A condition where the body does not have enough red blood cells or the red blood cells do not have enough hemoglobin, leading to fatigue and dizziness.
  • Dehydration: Inadequate fluid intake can lead to dehydration, causing symptoms such as dizziness, fatigue, and shakiness.
  • Anxiety or Panic Disorder: These conditions can cause physical symptoms such as shakiness and dizziness, along with extreme fatigue.
  • Vitamin Deficiencies (e.g., B12 or Iron): Deficiencies in certain vitamins can lead to fatigue, dizziness, and other neurological symptoms.

Do Not Miss Diagnoses

  • Cardiac Conditions (e.g., Arrhythmias, Heart Failure): Certain heart conditions can cause dizziness, fatigue, and shakiness due to inadequate blood flow or irregular heart rhythms.
  • Neurological Conditions (e.g., Multiple Sclerosis, Parkinson's Disease): These conditions can cause a wide range of symptoms, including fatigue, dizziness, and tremors.
  • Infections (e.g., Sepsis, Meningitis): Severe infections can cause systemic symptoms such as fatigue, dizziness, and shakiness, and require prompt medical attention.
  • Endocrine Disorders (e.g., Thyroid Disorders, Adrenal Insufficiency): Certain endocrine conditions can cause fatigue, dizziness, and other systemic symptoms.

Rare Diagnoses

  • Mitochondrial Myopathies: A group of rare genetic disorders that affect the mitochondria, leading to muscle weakness, fatigue, and other systemic symptoms.
  • Wilson's Disease: A rare genetic disorder that causes copper accumulation in the body, leading to neurological and systemic symptoms such as fatigue, dizziness, and tremors.
