If symptoms of indigestion and nausea appear in the short term, they may be caused by exposure to cold, improper diet, medication factors, and so on. In such cases, adjusting the diet or discontinuing the related medication should gradually relieve the symptoms.

If this condition persists for a long period, it is necessary to rule out upper gastrointestinal issues. Initial steps should include relevant examinations, commonly involving procedures such as gastroscopy, tests for Helicobacter pylori, or upper gastrointestinal imaging, etc. Based on the results of these tests, targeted treatment should be administered, such as eradicating Helicobacter pylori. If there is no Helicobacter pylori infection, symptomatic treatment should be considered, such as enhancing gastric motility, protecting the gastric mucosa, or suppressing stomach acid, etc.
