Differential Diagnosis for Recurrent Vomiting
Single Most Likely Diagnosis
- Gastroenteritis: This is often the most common cause of recurrent vomiting, typically resulting from a viral or bacterial infection that inflames the stomach and intestines, leading to symptoms like vomiting, diarrhea, and abdominal cramps.
Other Likely Diagnoses
- Food poisoning: Similar to gastroenteritis, food poisoning from consuming contaminated or spoiled food can lead to recurrent vomiting, along with other symptoms such as diarrhea and stomach cramps.
- Gastritis: Inflammation of the stomach lining can cause recurrent vomiting, often accompanied by abdominal pain and nausea.
- Pregnancy: Morning sickness is a common symptom of early pregnancy, characterized by recurrent vomiting, especially in the morning.
- Medication side effects: Certain medications can cause vomiting as a side effect, including chemotherapy drugs, antibiotics, and pain relievers.
Do Not Miss Diagnoses
- Appendicitis: Although less common, appendicitis can present with vomiting, especially if the appendix ruptures, leading to peritonitis, a life-threatening condition.
- Intestinal obstruction: A blockage in the intestines can cause severe vomiting, constipation, and abdominal pain, requiring immediate medical attention.
- Pancreatitis: Inflammation of the pancreas can lead to recurrent vomiting, along with severe abdominal pain and potentially life-threatening complications.
- Meningitis: In some cases, especially in children, meningitis can present with vomiting, along with symptoms like headache, fever, and stiff neck.
Rare Diagnoses
- Brain tumors: Certain brain tumors, especially those in the posterior fossa or cerebellum, can cause increased intracranial pressure, leading to recurrent vomiting.
- Cyclic vomiting syndrome: A rare condition characterized by recurring episodes of severe vomiting, often without an identifiable cause.
- Gastroparesis: A condition where the stomach muscles are weakened, leading to delayed stomach emptying and recurrent vomiting.
- Addison's disease: A rare endocrine disorder where the adrenal glands do not produce enough cortisol and aldosterone, potentially causing vomiting among other symptoms.
