What causes persistent nausea in the stomach?

Stomach disorders are becoming an increasingly common health issue affecting people across all age groups. These conditions are primarily linked to daily dietary habits. Stomach disorders manifest with a variety of symptoms, the most frequent being stomach pain or bloating and excess gas; in more severe cases, nausea and vomiting may occur. Targeted treatment is essential, as these symptoms can stem from conditions such as gastritis, gastroenteritis, and other gastrointestinal diseases. So, what causes persistent nausea originating from the stomach?

What Causes Persistent Nausea Originating from the Stomach?

Nausea localized to the stomach region is commonly associated with chronic pharyngitis. Patients with pharyngitis often experience sensations of a foreign body, itching, pain, nausea, and even vomiting in the throat—mainly triggered by irregular eating patterns or excessive consumption of spicy, irritating foods. Smoking and alcohol consumption can also contribute to pharyngitis. In elderly individuals, elevated blood pressure (hypertension) frequently leads to dizziness, nausea, and fatigue—especially upon waking in the morning, when blood pressure tends to surge. Gastrointestinal diseases—including acute or chronic gastritis, gastric ulcers, and duodenal ulcers—can disrupt normal gastrointestinal motility, causing retrograde peristalsis and resulting in nausea. Such cases are typically accompanied by upper abdominal pain, bloating, belching, and acid reflux.

Stomach pain should not be dismissed as simple indigestion—it may indicate a peptic ulcer, such as a gastric ulcer. A gastroscopy is recommended to confirm the diagnosis. Typical symptoms of gastric ulcers include upper abdominal pain centered around the epigastric region or midline of the upper abdomen, characterized by burning, hunger-like, dull, or intermittent pain. This discomfort is often relieved by eating, drinking, or consuming alkaline foods like steamed buns. Stomach pain accompanied by bloating is commonly caused by gastritis—an inflammatory condition of the gastric mucosa arising from various etiologies. The most prevalent forms are chronic superficial gastritis and chronic atrophic gastritis. Key clinical manifestations include loss of appetite, epigastric discomfort or dull pain, acid regurgitation, nausea, and vomiting.

It is advisable to consume nutritionally rich, light, and easily digestible foods; cultivate healthy eating habits—such as eating smaller, more frequent meals, avoiding overeating or binge eating, chewing food thoroughly, swallowing slowly, and maintaining regular, consistent meal times. Spicy, raw, and cold foods should be avoided. We hope this information proves helpful to you.
