Nearly everyone experiences acid reflux symptoms such as heartburn and nausea at some point. Bing Zhang, MD, a gastroenterologist with the 喵咪社区 Digestive Health Institute, part of 喵咪社区, who provides services at , says acid reflux is one of the most common issues he addresses with patients. Additionally, the estimates 1 in 5 Americans has gastroesophageal reflux disease (GERD).
Luckily, most people who experience acid reflux can manage symptoms largely with lifestyle changes and over-the-counter medications.
What causes acid reflux? The stomach produces acid to digest food. Reflux occurs when the acid travels up into the esophagus through the lower esophageal sphincter (LES), which is the valve that connects the stomach and the esophagus.
鈥淭hink of it as the doorway between the stomach and the esophagus,鈥 Dr. Zhang says. If this valve fails to close properly, 鈥渢he contents in your stomach can come back up.鈥
Acid reflux symptoms include:
It鈥檚 common to experience acid reflux symptoms after eating a large meal or while lying down. Patients who are pregnant or overweight may experience acid reflux more often.
To address acid reflux, 鈥淚 usually recommend lifestyle and dietary changes first,鈥 Dr. Zhang says.
He explains that certain foods and drinks can 鈥渄ecrease the tightness of the LES鈥 and lead to acid reflux symptoms. These foods and other common triggers include:
鈥淎nother thing is chewing gum, because it causes you to swallow a lot of saliva and air. When you swallow a lot of air, it has to come out,鈥 Dr. Zhang says. He adds that foods like popcorn and cotton candy can have a similar effect if eaten in large quantities because of the air they contain. Avoiding trigger foods and drinks can help patients prevent acid reflux symptoms.
Home remedies to prevent acid reflux include lifestyle adjustments. One option Dr. Zhang recommends is to have your biggest meal earlier in the day and eat a smaller dinner.
鈥淭his is because after dinner, we may start relaxing and lie down. But staying upright for at least two or three hours after eating helps with digestion,鈥 Dr. Zhang says, pointing out that people are more likely to remain sitting up or be active after eating in the middle of the day.
He also discourages eating fatty or greasy foods in the evening because they decrease the speed of digestion. 鈥淏y the time you go to sleep, the greasy food is still in your stomach,鈥 which can cause acid reflux symptoms at night.
Other solutions include using extra pillows to keep the head elevated while sleeping and wearing looser clothing that doesn鈥檛 press on the stomach.
鈥淲eight loss is also key because it decreases the pressure on the stomach,鈥 he adds.
For occasional acid reflux, Dr. Zhang says familiar over-the-counter acid reflux medicine such as Pepcid, Tums and Mylanta can help get rid of acid reflux quickly. 鈥淭hey鈥檙e the fastest because they neutralize the acid that comes up,鈥 he explains.
Proton pump inhibitors (PPIs) with brand names like Prevacid, Prilosec and Nexium are also available without a prescription.
鈥淧PIs stop the protein that produces stomach acid,鈥 Dr. Zhang says. 鈥淭he important thing with a PPI is to remember to take it on an empty stomach at least 30 minutes to an hour before eating.鈥
There are surgical procedures to address severe acid reflux or GERD, but Dr. Zhang says they may be considered if the combination of lifestyle and dietary modifications along with medications fail to control the symptoms. 鈥淭he acid reflux has to be pretty bad before you鈥檇 consider more invasive interventions. Most people choose against that route.鈥
For patients experiencing chronic acid reflux that interrupts their daily life, Dr. Zhang advises talking to their doctor about it.
