Can you have stomach flu without vomiting?

Gastroenteritis affects the stomach and intestines, but people do not all develop the same combination of symptoms. Diarrhoea, abdominal pain, nausea, fever, and loss of appetite may occur with or without vomiting. Rotavirus infection is one possible cause, particularly in children. Other infections, food-related irritation, or non-infectious digestive problems can look similar, so the duration and severity of symptoms matter.

Drink regularly, using small amounts if nausea is present. Water, broth, and oral rehydration drinks can help replace fluid losses. Eat simple foods when hungry, such as rice, toast, potatoes, bananas, or soup, then move back to normal meals as your appetite returns. Wash hands with soap and water, clean shared bathroom surfaces, and avoid preparing food for others while infectious symptoms continue. Rest and monitor urination.

Seek advice if diarrhoea is severe or persistent, fluids are difficult to replace, urine becomes scarce, or dizziness and weakness develop. Get prompt care for blood in stool, severe or localised abdominal pain, confusion, fainting, or a persistent fever. A young child, older adult, pregnant person, or someone with chronic illness may become dehydrated more quickly and should be assessed earlier when symptoms are concerning.

Ask how much fluid is appropriate, whether testing is needed, and which changes in stool, pain, or fever should trigger follow-up.
