6 Tips to Ease Exercise Heartburn

Is your heartburn triggered by running, aerobics, or other forms of exercise?

You exercise to feel the burn -- but not that kind of burn. Muscles, yes. Stomach, no. But when you go running, do aerobics, or go to an indoor cycling class, there it is: heartburn. It's not just your legs that are churning, it's your last meal as well, churning right up into your throat. Your exercise heartburn has even made you hesitate to work out and made you wonder: What's going on here?

What Causes Exercise Heartburn?

Exercise can trigger heartburn if the LES muscle (the lower esophageal sphincter) is weak or too relaxed, and food or stomach acid "burps" back up from your stomach into your esophagus.

Exercise-induced heartburn can also be triggered by certain foods -- especially spicy foods like tomato sauce, acidic foods like orange juice, carbonated sodas, coffee, chocolate, and alcohol. These are the most common triggers for heartburn, according to the American Gastroenterological Association (AGA).

6 Tips When Exercise Triggers Heartburn

You don’t need to give up exercise to avoid heartburn. Instead, try these tips:

1. Problem-solve your diet. Do some simple problem-solving, says Tara O'Brien, PharmD, a pharmacy manager at Pharmaca in Seattle, a national, integrative pharmacy combining Western medicine with self-care. "Specifically, do you eat relatively quickly before going for a run? And what types of food?" Cut out the offending foods -- and hold the triple mochas before running.

2. Eat something soothing before exercise. "Some people eat a yogurt before a run and don't experience any problems, while the next person may eat yogurt and experience the worst heartburn ever," says O'Brien. "Experiment with foods to see if one thing aggravates it more than another." Good places to start? A banana, yogurt, small bowl of whole-grain cereal or toast.

3. Eat two to three hours before working out. Play with how long before you exercise to eat your light snack -- a half-hour, hour, 2 hours before -- and see which works best. Maybe you can eat a small snack an hour before exercise with no problem. Or you may need to eat two to three hours before working out to give your stomach time to empty.

4. Rethink your workout. Certain kinds of exercise may trigger heartburn for some people more than others. Experiment to see whether certain workouts trigger heartburn more or less for you. Maybe you can take an indoor cycling class or go hiking if high-impact aerobics or running hurt. Crunches and core work on a full stomach may have to go. Headstands and Downward Dog in yoga, which reverse the natural gravity of digestion, can also trigger heartburn; ask your teacher how to modify these inverted poses.

5. Try baking soda. Taking something for symptoms wouldn't hurt, says O'Brien. Several natural remedies exist, although they only provide temporary relief. Baking soda added to water can help neutralize and wash away stomach acids. Because baking soda may add more salt to your diet, it's best to speak to your doctor first before trying this remedy.

6. Try over-the-counter relief. In your local pharmacy, look for an antacid with calcium -- that's the ingredient that neutralizes stomach acid. "Chewing a Tums or taking a calcium-based antacid is very safe, so it would be worth a try," says O'Brien. Although these are fast-acting, symptom-relief antacids, it can't hurt to try one as a preventive measure before exercise.
