What causes persistent nausea and vomiting?

In real life, some patients notice persistent adverse symptoms such as nausea, which not only diminishes their quality of life but also causes significant psychological distress. So, what could be causing persistent feelings of nausea and vomiting?

What Causes Persistent Nausea and Vomiting?

Persistent nausea and vomiting may stem from gastrointestinal dysfunction—for instance, indigestion, impaired gastric motility, delayed gastric emptying, nausea and vomiting, acid reflux, or abdominal distension. In such cases, oral gastric mucosal protective agents—such as aluminum carbonate tablets—may be taken. For more severe cases, prokinetic agents (e.g., mosapride) and digestive aids (e.g., yeast tablets) may be prescribed.

Patients should adopt a diet consisting of small, frequent meals of easily digestible liquid or soft foods—such as light noodles or congee. They should also consume ample fresh vegetables and fruits to ensure adequate intake of various vitamins. Foods that cause bloating or are difficult to digest—such as glutinous rice, chestnuts, and sweet potatoes—should be limited. Additionally, spicy, stimulating, raw, cold, or greasy foods should be minimized. Regular physical activity and sufficient sleep are also recommended. Chronic nausea often results from weakened gastrointestinal function, possibly due to irregular or careless eating habits; consuming irritating foods can trigger excessive gastric acid secretion, leading to nausea and vomiting.

Patients are advised to pay close attention to their dietary habits and avoid spicy foods. We hope this information proves helpful.
