This looks like a stomach infection or food-related gastric upset causing vomiting, loose motions, abdominal discomfort, and weakness. Since it started only a few hours ago, the main focus right now should be preventing dehydration and controlling the vomiting.
Make sure the patient drinks plenty of fluids in small amounts frequently, such as ORS, coconut water, rice water, lemon water, or clear soups. Avoid oily, spicy, outside food, milk products, and heavy meals for the next day or two. Soft foods like rice, banana, toast, curd, and khichdi are usually easier to tolerate.
For vomiting, Ondansetron 4 mg can be taken if needed. A probiotic capsule or sachet twice daily for a few days can help with loose motions. If there is significant abdominal cramping, an antispasmodic medicine may also help. Weakness is usually due to fluid loss and generally improves once hydration becomes adequate.
This is commonly seen and most patients improve with rest, fluids, and supportive treatment over the next one to two days.
Next Steps
At this stage, antibiotics are usually not needed unless there is high fever, blood in stool, severe abdominal pain, or symptoms becoming persistent. If vomiting continues, urine output decreases, dizziness worsens, or symptoms do not improve within 24–48 hours, then medical evaluation is necessary and IV fluids may be required.
