Differential Diagnosis for Vomiting in an 84-year-old

Single Most Likely Diagnosis

  • Gastroesophageal reflux disease (GERD) or gastritis: This is a common condition in the elderly, often exacerbated by age-related decreases in lower esophageal sphincter tone, increased prevalence of hiatal hernia, and the use of medications that can irritate the stomach lining.

Other Likely Diagnoses

  • Constipation: Although it might seem unrelated, constipation can cause nausea and vomiting, especially in the elderly, due to the buildup of toxins or the physical pressure exerted by a full bowel.
  • Medication side effects: Many medications commonly used in the elderly, such as antibiotics, NSAIDs, and certain cardiovascular drugs, can cause vomiting as a side effect.
  • Urinary tract infection (UTI): UTIs are common in the elderly and can present with non-specific symptoms, including vomiting, especially if the infection has progressed to involve the kidneys (pyelonephritis).
  • Acute gastroenteritis: Viral or bacterial infections can cause vomiting and are common in all age groups, including the elderly.

Do Not Miss Diagnoses

  • Myocardial infarction (MI): Although less common, vomiting can be a presenting symptom of MI in the elderly, especially in women and those with diabetes, due to decreased sensation of chest pain.
  • Appendicitis: Although rare in the elderly, appendicitis can present atypically with vomiting, and its diagnosis should not be missed due to the high risk of perforation and subsequent mortality.
  • Intestinal obstruction: This condition requires prompt diagnosis and treatment to prevent severe complications, including bowel ischemia and perforation.
  • Central nervous system (CNS) disorders: Conditions such as stroke, CNS infections, or increased intracranial pressure can cause vomiting and are critical to diagnose early.

Rare Diagnoses

  • Gastroparesis: A condition characterized by delayed stomach emptying, which can be caused by diabetes, certain medications, or post-viral infections.
  • Inflammatory bowel disease (IBD): Although more common in younger populations, IBD (including Crohn's disease and ulcerative colitis) can present at any age and should be considered in the differential diagnosis of chronic vomiting.
  • Neurological disorders: Such as Parkinson's disease or other movement disorders that can affect the gastrointestinal system and cause vomiting.
  • Endocrine disorders: Like adrenal insufficiency or thyroid disorders, which can cause vomiting among other symptoms.
