Single Most Likely Diagnosis

Other Likely Diagnoses
- Peptic Ulcer Disease: This condition can cause stomach pain and vomiting, especially if the patient has a history of NSAID use or Helicobacter pylori infection. The patient's age and symptoms make this a possible diagnosis.
- Food Poisoning: This is another common cause of stomach pain and vomiting, especially if the patient has recently consumed undercooked or contaminated food.
- Irritable Bowel Syndrome (IBS): Although IBS is a chronic condition, it can cause acute episodes of stomach pain and vomiting. The patient's symptoms and age make this a possible diagnosis.
Do Not Miss Diagnoses
