Know your triggers
Your triggers for upset stomach might be certain foods, drinks or eating habits, or they might be stress, anxiety or nervousness. Keep an eye on your diet (write a food diary if you’re still trying to identify trigger foods) and keep stress at bay by doing regular exercise and making time to relax.
Keep your digestive system fit
Exercise is good for your digestion, and it's useful to know that there’s something simple you can do to help avoid diarrhea. Exercise is a great stress buster too, which is doubly good news if stress and tension trigger an upset stomach for you.
Try a probiotic
Studies suggest that probiotics can help reinforce your digestive system and lower your chances of getting diarrhea, especially if you’re prone to it when taking medication. So next time you’re prescribed a course of antibiotics, take regular probiotics, which you can find in certain yoghurts and other foods or take as food supplements.
