Differential Diagnosis for Left Upper Quadrant Pain after Meals

Single Most Likely Diagnosis

  • Gastroesophageal Reflux Disease (GERD): This condition is characterized by stomach acid frequently flowing back into the tube connecting the mouth and stomach (esophagus). Symptoms can include pain in the upper abdomen, especially after eating, which aligns with the described symptoms.

Other Likely Diagnoses

  • Peptic Ulcer Disease: Ulcers in the stomach or duodenum can cause pain that worsens after eating due to increased acid production. The location of the pain can sometimes be felt in the left upper quadrant.
  • Functional Dyspepsia: This condition involves recurring signs and symptoms of indigestion that have no obvious cause. Symptoms can include pain or discomfort in the upper abdomen, which may worsen after eating.
  • Gastritis: Inflammation of the stomach lining can cause upper abdominal pain, nausea, and vomiting, especially after eating.

Do Not Miss Diagnoses

  • Myocardial Infarction: Although less common, myocardial infarction (heart attack) can present with epigastric or upper abdominal pain that may be confused with gastrointestinal issues. It's crucial to consider this diagnosis, especially in patients with risk factors.
  • Pancreatitis: Inflammation of the pancreas can cause severe upper abdominal pain that radiates to the back and worsens after eating. It's a serious condition that requires prompt medical attention.
  • Splenic Infarction or Rupture: Conditions affecting the spleen, such as infarction or rupture, can cause severe left upper quadrant pain and are medical emergencies.

Rare Diagnoses

  • Gastric Cancer: Although rare, gastric cancer can present with upper abdominal pain, weight loss, and difficulty eating. It's more common in certain populations and those with a family history.
  • Splenic Artery Aneurysm: A rare condition where an aneurysm forms in the splenic artery, potentially causing left upper quadrant pain and requiring urgent medical attention if ruptured.
  • Left Diaphragmatic Hernia: A rare condition where part of the stomach or other abdominal organs protrude through the diaphragm into the chest cavity, potentially causing upper abdominal pain and other respiratory symptoms.
