Stomach bug relief

Gastroenteritis irritates the digestive tract and may cause vomiting, diarrhoea, nausea, abdominal discomfort, fever or poor appetite. Relief measures reduce strain while the body recovers; they do not necessarily remove the underlying infection immediately. Dehydration is the main problem to prevent when fluid leaves the body faster than it is replaced.

Symptoms can vary from mild queasiness to repeated vomiting and severe cramps. A sudden change, worsening pain or a symptom that does not fit a typical stomach illness should prompt medical advice rather than continued home treatment.

Take small, regular sips of water or an oral rehydration drink. Rest and avoid large meals until nausea settles. Then try simple foods in modest portions, such as soup, rice, toast or yoghurt, and return to your usual diet as comfort allows. A cool room and loose clothing may help if fever or nausea makes you uncomfortable.

Ask a pharmacist before taking medicines for vomiting, diarrhoea or pain, especially if you are pregnant, treating a child, have kidney disease or take regular medicines. Avoid alcohol and do not use leftover antibiotics. Wash hands with soap and water to help protect people around you.

Seek urgent medical care for fainting, confusion, severe weakness, severe or worsening abdominal pain, blood in vomit or stool, or inability to keep fluids down. Arrange prompt advice if you are urinating much less, symptoms continue to worsen, or you cannot maintain drinking. Vulnerable people may need assessment sooner.

Ask which fluid replacement product is right for you, whether a symptom medicine is safe, and what change would mean you need examination. Describe the pattern of vomiting and diarrhoea, pain location, fever, urine output, recent food or travel and any exposure to someone unwell.
