Differential Diagnosis
- Single most likely diagnosis:
- B. Carbohydrate malabsorption: This is a common cause of gastrointestinal symptoms such as bloating, gas, and diarrhea, especially if the patient has recently consumed a high amount of carbohydrates or has a known intolerance to certain types of carbohydrates like lactose or fructose.
- Other Likely diagnoses:
- A. Bile salt malabsorption: This condition can cause chronic diarrhea, abdominal pain, and fat malabsorption, and is often seen in patients with a history of gastrointestinal surgery or certain medical conditions.
- E. Relapse of viral gastroenteritis: Viral gastroenteritis can cause a range of symptoms including diarrhea, vomiting, and abdominal pain, and relapses can occur, especially if the underlying cause is not fully resolved.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- C. Clostridioides difficile infection: Although this may not be the most likely diagnosis, it is a serious and potentially life-threatening condition that requires prompt diagnosis and treatment, especially in patients with a history of antibiotic use or recent hospitalization.
- Rare diagnoses:
- D. Milk protein-induced allergic proctocolitis: This is a rare condition that typically affects infants and young children, causing rectal bleeding and other gastrointestinal symptoms in response to milk protein exposure. It is less likely in adults, but should be considered in patients with a history of milk protein allergy or intolerance.
