Even after you’ve got diarrhoea symptoms under control, you should still rehydrate. You’ll have lost important electrolytes, water, minerals, salt and sugars each time you go to the loo. You want to give your body the best chance of recovering and feeling better, so you need to be replenishing what’s been lost. Rehydrate by taking a rehydration sachet, or just sipping on some water, diluted squash or fruit juice. It’s best to stay away from fizzy drinks, tea and coffee (save the good stuff for when you’re feeling better).
