When suffering from a stomach flu, symptoms often include abdominal pain, diarrhea, and bloating. If the symptoms are mild, it is recommended that patients take some antispasmodic and pain relief medications orally. In terms of diet, it is best to avoid irritant foods and consume oral rehydration salts to prevent electrolyte imbalance and significant fluid loss. If the patient experiences severe diarrhea, it is advisable to appropriately supplement with sugar and electrolyte solutions or liquids. If the condition worsens, the use of antibiotics and antiviral medications may be considered.
