It may help to make a few short-term dietary adjustments while your bowels recover from acute diarrhoea. Get a consultation by your medical professional, but general suggestions include; Limit consumption of fatty, sweet, or spicy foods. Avoid alcohol. Increase consumption of starchy foods like banana, rice and bread. Increase consumption of yoghurt containing live cultures. Diarrhoea in babies and young children can be caused by fruit juice, so limit these drinks.
