Eating and Exercise
Did you know everyday habits, such as strenuous exercise and how you eat can lead to heartburn? Workouts that put pressure on the abdomen, such as heavy lifting and stomach crunches, can increase the risk of heartburn as they can relax the lower esophageal sphincter (LES) muscle, which can lead to food or stomach acid coming back up into the esophagusi. When it comes to diet, overeating can cause your stomach to distend, increasing the chance of acid reflux which causes heartburn. Eating too rapidly can also trigger heartburnii, meaning it’s important to chew your food slowly. Not only will your body better digest your meals, but you may suffer from heartburn less too.

Heartburn Caused by Drink
Avoiding coffee and caffeinated beverages such as sports energy drinks can help reduce the risk of heartburn. It's best to moderate alcoholic drinks such as beer and wine, which can increase stomach acid levels. Alcohol has also been shown to relax the lower esophageal sphincter (LES) muscle. The LES acts as a barrier between your food pipe (esophagus) and your stomach. By not closing fully after food has entered the stomach, acid can travel up the esophagus, sparking common heartburn symptoms.iv Drinking carbonated drinks can also increase heartburn, especially at night.
Medications and Heartburn
Some common medications, including prescription and over-the-counter drugs, can cause heartburn as a side effect.v Always read the label and consult your doctor when starting new medications if you suffer from heartburn.
Heartburn During Pregnancy
Indigestion and heartburn are common in pregnancy, especially during the second and third trimesters.

As your pregnancy progresses, your growing baby places increased pressure on your stomach, again raising the risk of heartburn.vi
