Differential Diagnosis for Persistent Nausea, Vomiting, and Weight Loss

Single Most Likely Diagnosis

  • Gastroparesis: This condition is characterized by delayed stomach emptying, which can cause nausea, vomiting, and weight loss. The symptoms persisting after discontinuing Ozempic (semaglutide), which can slow gastric emptying, suggest an underlying issue with gastric motility.

Other Likely Diagnoses

  • Gastroesophageal Reflux Disease (GERD): Persistent nausea and vomiting could be indicative of GERD, especially if symptoms worsen after eating or at night.
  • Peptic Ulcer Disease: Ulcers in the stomach or duodenum can cause persistent nausea, vomiting, and weight loss due to the pain and difficulty in eating.
  • Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can lead to chronic nausea, vomiting, and weight loss due to inflammation in the gastrointestinal tract.
  • Small Intestine Bacterial Overgrowth (SIBO): An overgrowth of bacteria in the small intestine can cause nausea, vomiting, and weight loss due to malabsorption of nutrients.

Do Not Miss Diagnoses

  • Gastric Cancer: Although less common, gastric cancer can present with persistent nausea, vomiting, and weight loss. It is crucial to rule out this diagnosis due to its severe prognosis if missed.
  • Pancreatic Cancer: Similar to gastric cancer, pancreatic cancer can cause these symptoms and has a high mortality rate if not diagnosed early.
  • Addison's Disease: This rare endocrine disorder can cause persistent nausea, vomiting, and weight loss due to adrenal insufficiency.

Rare Diagnoses

  • Celiac Disease: An autoimmune reaction to gluten can cause malabsorption, leading to nausea, vomiting, and weight loss in some cases.
  • Whipple's Disease: A rare bacterial infection that affects the small intestine, causing malabsorption and weight loss.
  • Superior Mesenteric Artery Syndrome: A rare condition where the duodenum is compressed by the superior mesenteric artery, leading to nausea, vomiting, and weight loss due to obstruction.
