I have recurring diarrhoea every few weeks. it starts with burps and then a few hours later runny tummy. ive tried probiotics and imodium. nothing works. dont know what causes it to start. usually lasts approx 3 days. can i cure / prevent this?

See your GP: We don't know enough about your overall health history to be able to give you a more specific answer than to see your GP for an exam and appropriate testing, including testing for parasites. Once that is done if no cause is found, see a gastroenterologists. In the meantime, avoid ibuprofen, naproxen, aspirin and other drugs in that class. Also avoid Splenda (sucralose) and Stevia.
