What Causes Nausea and Vomiting Originating from the Stomach?

Nausea and vomiting originating from the stomach may result from conditions such as gastritis, acute gastroenteritis, peptic ulcers, or pregnancy in women. Food can irritate the gastric mucosa, triggering reflexive nausea and vomiting. Most patients with acute gastroenteritis consume unhygienic, frozen, or cold foods, which irritate the gastrointestinal tract and lead to gastric nausea and vomiting—often accompanied by diarrhea and abdominal pain. This condition is especially common during hot summer months. Gastric acid irritating the ulcer surface can also cause gastric discomfort, nausea, vomiting, and acid reflux. Early pregnancy in women may likewise induce nausea and vomiting.

Patients should maintain a light, balanced diet and avoid overeating at each of the three daily meals. Spicy and cold foods should be avoided; fried, greasy, and sweet foods should be consumed sparingly. Instead, emphasize fresh fruits and vegetables. Engage in moderate physical activity and ensure adequate rest. If gastritis or gastric ulcers are diagnosed, timely gastroscopy and active treatment are essential. In cases of Helicobacter pylori infection, targeted eradication therapy is necessary.
