Gastroenteritis refers to bacterial and viral infections of the bowels. The resulting stomach pain is sometimes accompanied by nausea, vomiting, diarrhoea, or a combination of these symptoms. Not normally a serious condition, gastroenteritis often does not require treatment and resolves itself in a few days.
If you are suffering with symptoms from gastroenteritis though, it is vital that you get plenty of rest, drink lots of fluids (water or squash), eat when you feel able, and you can use paracetamol if required for pain. Avoid any fizzy drinks or fruit juices. You should also take precautions to avoid passing it on to others, such as washing your hands regularly and staying off work until you have been clear of symptoms for two days.
You should seek medical advice if the condition continues for an unusually long period or if you are suffering from repeated bouts of it – this could indicate that you have an underlying disorder, such as irritable bowel syndrome (IBS).
