Stomach ache, cramps, vomiting or diarrhoea might be caused by a few things, but most often they are caused by a bug and are short-lived.
An upset stomach can usually be treated at home and should get better within a few days.
There are medicines available over the counter to help ease some symptoms and a pharmacist can help you find what you need.
Norovirus is the most common stomach bug in the UK and is particularly common in the winter months.
With sickness and diarrhoea caused by a bug (like norovirus), a full recovery will usually be made within 2-3 days.
An upset stomach caused by foods or intolerances should last no more than 1-2 days.
Symptoms of a stomach bug may include:
Your local pharmacist can help advise you on steps to take and medicines to help ease an upset stomach, such as Imodium for diarrhoea.
If you think you have a food intolerance or IBS, it’s a good idea to keep a food diary for a couple of weeks, noting down everything you eat or drink and when you get an upset stomach.
