Changes

* Try taking a Gas-x before running. It removes the bubbles in your stomach (anti-foaming) and is not absorbed into the blood stream, so there should be no downsides.

* Many people find a little ginger can help settle the stomach, so a little ginger ale or ginger beer could help. Ginger chews also help, or some crystallized ginger. Like the chomps, take it within 5 minutes of starting your run to avoid a blood sugar crash.

* Dairy can cause upsets even if you're not normally lactose intolerant. On the other hand, some live yoghurt can help keep your digestive system healthy.

* NSAIDs, such as ibuprofen and aspirin irritate the stomach and should be avoided. They prevent healing as well – [[NSAIDs and Running]]
