In adults and older children diarrhoea and vomiting usually settles on its own.

Fluid replacement is important with sachets of powder such as Dioralyte or Rehidrat, which can be made into a drink, and are available from your chemist. Gradually reintroduce solids once vomitting has settled.

You should contact your doctor if diarrhoea contains blood or if you have severe pain or a high temperature.

In small babies and young children careful treatment is required. Your doctor will be able to advise you by phone or arrange to see you if necessary.
