This is essential treatment for DIARRHOEA, particularly in children. There are a number of proprietary preparations, often dispensed as flavoured sachets, including Dioralyte® and Rehydrat®. In the developing world, ‘home-made’ preparations, such as a litre of water containing one teaspoonful of salt and eight of sugar, may be used. These solutions replace salt and water lost because of the diarrhoea and usually no other treatment is required.
