　　What Causes Persistent Nausea and Vomiting?

　　A persistent sensation of nausea and vomiting may stem from abdominal disorders, including gastrointestinal obstruction, gastric spasm, cholecystitis, pancreatitis, or hepatic dysfunction. Relevant diagnostic tests should be performed to confirm the underlying cause. Alternatively, this symptom may arise from neurological conditions—such as acute cerebral infarction, acute intracerebral hemorrhage, increased intracranial pressure, or posterior circulation ischemia. A thorough neurological physical examination and cranial imaging can aid diagnosis; patients may also present with associated symptoms like dizziness or motor deficits.

　　Chronic nausea and vomiting may indicate liver impairment, chronic pancreatitis, dyspepsia, or even gastric cancer. The liver plays a vital role in bile secretion and in metabolizing dietary fats and proteins. When liver function is compromised, bile secretion diminishes and food metabolism is disrupted, leading to reduced appetite—and particularly triggering nausea and vomiting upon exposure to greasy foods. The pancreas secretes digestive enzymes essential for breaking down food in the stomach. In chronic pancreatitis, impaired pancreatic enzyme secretion hinders digestion, resulting not only in upper abdominal pain but also in nausea and vomiting.

　　Patients are advised to avoid excessively fatty foods and adopt a balanced, light diet. We hope this article proves helpful to you.
