Differential Diagnosis
- Single most likely diagnosis
- Post-treatment irritable bowel syndrome (IBS) or functional dyspepsia: The symptoms of stomach pain, nausea, bloating, and mucus in stool 2 weeks after H. pylori treatment could be related to the treatment itself or the underlying condition that led to the H. pylori infection. IBS and functional dyspepsia are common conditions that can cause these symptoms.
- Other Likely diagnoses
- Persistent H. pylori infection: It's possible that the treatment was not effective, and the H. pylori infection is still present, causing the symptoms.
- Gastroesophageal reflux disease (GERD): The symptoms of stomach pain, nausea, and bloating could be related to GERD, especially if the pain occurs after food.
- Small intestine bacterial overgrowth (SIBO): The presence of mucus in stool and bloating could be indicative of SIBO, which can cause similar symptoms.
- Do Not Miss
- Gastric cancer: Although rare, gastric cancer can cause stomach pain, nausea, and bloating, and it's essential to rule out this diagnosis, especially if the patient has a history of H. pylori infection.
- Peptic ulcer disease: The symptoms could be related to a peptic ulcer, which can be a complication of H. pylori infection or NSAID use.
- Inflammatory bowel disease (IBD): The presence of mucus in stool and abdominal pain could be indicative of IBD, such as Crohn's disease or ulcerative colitis.
- Rare diagnoses
- Giardiasis: The symptoms of stomach pain, nausea, bloating, and mucus in stool could be related to a giardia infection, although this is less common.
- Celiac disease: The presence of abdominal pain, bloating, and mucus in stool could be indicative of celiac disease, although this is relatively rare.
- Eosinophilic gastroenteritis: This rare condition can cause stomach pain, nausea, and bloating, and is often associated with eosinophilia.
