​Dr Clarence Kwan, Head and Consultant, Department of Gastroenterology and Hepatology Service, SKH, shared that for most healthy individuals, gastroenteritis usually resolves on its own without the need for medication. Patients are generally advised to drink enough water to replenish the fluids lost due to vomiting and diarrhea, avoid physical activities that may increase the risk of dehydration, and ensure personal hygiene to reduce the risk of infection.

Dr Kwan points out that medical attention should be sought if the individual is unable to tolerate oral fluids (e.g. continuous vomiting), and if symptoms fail to resolve or get better within 48 to 72 hours, or when blood is present in vomit or diarrhea. Specific groups of individuals should also seek medical attention if they contract gastroenteritis, including infants and the elderly, who are more prone to dehydration, and those with certain chronic diseases or who are on long-term medications. 

Dr Kwan emphasised that gastroenteritis is typically contracted through the ingestion of contaminated food, hence food should be consumed within the "safe for consumption" timeframe. If food needs to be kept for later consumption, to ensure proper handling (e.g. using communal utensils for distribution rather than personal utensils that may be contaminated by saliva). Ensure there are hygienic practices in food preparation and that food is cooked thoroughly.
