Differential Diagnosis for Vomiting with Bloating
Single Most Likely Diagnosis
- Irritable Bowel Syndrome (IBS): This condition is characterized by recurring abdominal pain, bloating, and changes in bowel movements, which can include vomiting. The absence of fever, normal bowel movements, and lack of other symptoms make IBS a plausible diagnosis.
Other Likely Diagnoses
- Gastroesophageal Reflux Disease (GERD): GERD can cause vomiting and bloating due to the reflux of stomach acid into the esophagus, leading to discomfort and nausea.
- Functional Dyspepsia: This condition involves recurring signs and symptoms of indigestion that have no obvious cause, which can include bloating and vomiting.
- Food Intolerance: Intolerance to certain foods, such as lactose or gluten, can lead to bloating, vomiting, and other gastrointestinal symptoms without fever or changes in bowel movements.
Do Not Miss Diagnoses
- Gastric Outlet Obstruction: Although less likely, gastric outlet obstruction can cause vomiting and bloating. It's crucial to consider this diagnosis due to its potential severity and need for prompt intervention.
- Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can present with vomiting and bloating, among other symptoms. Early diagnosis is critical for effective management.
- Gastric Cancer: Though rare, gastric cancer can cause nonspecific symptoms including vomiting and bloating, especially in older adults.
Rare Diagnoses
- Cyclic Vomiting Syndrome: A rare condition characterized by recurring episodes of severe vomiting, which can be accompanied by bloating.
- Rumination Syndrome: A condition where food is regurgitated and then chewed and swallowed again, which can lead to bloating and vomiting.
- Gastroparesis: A condition where the stomach takes too long to empty its contents, leading to nausea, vomiting, and bloating.
