What should you know about stomach bug symptoms treatment?

Gastroenteritis can cause vomiting, diarrhoea, nausea, cramps, fever and loss of appetite. The immediate treatment priority is fluid and salt replacement because the body may lose both through vomiting and loose stools. Most uncomplicated cases are managed with supportive care, but similar symptoms can also come from food poisoning, medication effects or another illness. The pattern, severity and health of the person matter.

Sip water or an oral rehydration solution often, taking smaller amounts if nausea is strong. Continue breastfeeding when relevant. Eat when able, starting with foods that feel manageable rather than forcing a meal. Rest and avoid alcohol. A pharmacist can explain whether an anti-vomiting or diarrhoea medicine is suitable; some products are unsafe for children or inappropriate when there is blood in stool or fever. Antibiotics should only be used when prescribed for a specific reason.

Seek urgent assessment for severe dehydration, fainting, confusion, severe abdominal pain, blood in vomit or stool, or repeated vomiting that prevents drinking. Contact a clinician if symptoms are worsening, fever is concerning, or you are worried about a child, older adult, pregnant person or someone with a long-term illness. Take a list of medicines and describe fluid intake and urine output.

Ask which rehydration product to use, whether your medicines should be paused or changed, and whether testing is needed. Clarify what to give a child, how to restart food, and the exact warning signs that require same-day care.
