Chewing Gum After Meals Can Stop Acid Reflux in Its Tracks


  • I have studied the effects of chewing gum on reflux, and the data show that chewing gum after a meal — or alternatively, sucking on a hard candy — can stop acid reflux in its tracks, because  gum chewing increases saliva production, the acid-neutralizing salivary bicarbonate concentration AND increases swallowing rates. This drives the GI system forward helping to prevent backflow, reflux.
  • Gum chewing is an excellent “adjunctive” partial treatment for reflux. It really helps, particularly people who have symptoms (e.g., hoarseness, heartburn, cough, etc.) after meals.
  • Recommended are sugarless fruit or bubble gums, no mints. Cinnamon and ginger are also good. If you can find it, a gum that contains bicarb is best, available at some health food stores.
  • For people who don’t want to chew gum for aesthetic, dental, or TMJ reasons, sucking on a hard candy does the same thing and works well. Non-mint, sugar-free is recommended.
