When symptoms of diarrhoea and vomiting occur, the following points need to be noted with regard to diet.
Do not eat too much at once, and eat smaller and more frequent meals to reduce the burden on the stomach and intestines.
Take care to eat less cold, greasy and indigestible food. You can drink a moderate amount of water to prevent dehydration.
If you don’t vomit when you drink water, you can eat some thin rice or soup and noodle type food in moderation.
