More than 60 million people experience heartburn from acid reflux at least once a month in the United States, according to the American College of Gastroenterology. More than 15 million Americans have symptoms daily. About 20 percent of Americans have GERD.

Acid reflux is common and it can come and go, especially after eating certain foods. Normal people may have acid reflux for an hour a day and not feel anything. It may disappear without the help of medication.

But people with chronic heartburn need some form of treatment. If left untreated, GERD can lead to esophageal damage, cancer and other complications.

With the right treatment, the body may be able to heal. Depending on the severity of symptoms, a health care provider may recommend lifestyle changes, medications, surgery or a combination of these.

Symptoms

The most common symptom of acid reflux is heartburn. It feels like a burning pain that people feel mid-chest below the sternum. Sometimes, a person may taste food or stomach acid in the back of the mouth. It can get worse at night, when a person lays down or after meals.

Did You Know?

The most common symptom of acid reflux and GERD is heartburn.

When heartburn happens regularly two or more times a week, a person may have GERD. But not all adults with GERD have heartburn, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

Some symptoms of GERD come from its complications. These include Inflammation of the esophagus and breathing problems.

Common Symptoms of GERD in Adults

  • Difficult or painful swallowing
  • Foul breath
  • Nausea
  • Pain in the upper abdomen or chest
  • Problems with teeth wearing away
  • Respiratory problems
  • Vomiting

When to Call Your Doctor

If you have persistent symptoms that don’t go away with a change in diet or over-the-counter acid reducers, see your doctor right away.

Some serious symptoms include:

  • Blood in vomit
  • Difficulty breathing after vomiting
  • Difficulty swallowing
  • Green or yellow vomit
  • Large amounts of vomit
  • Pain in the mouth or throat when eating
  • Pain when swallowing
  • Projectile or forceful vomiting
  • Vomit that looks like coffee grounds

Causes and Risks of Acid Reflux

Acid reflux is caused by a weak or improperly closed lower esophageal sphincter — the muscle that closes the opening between the esophagus and the stomach. When people eat, the sphincter opens to allow food into the stomach. When people are not eating, this muscle stays closed.

When the muscle is weak or becomes relaxed when it isn’t supposed to, the contents of the stomach —including stomach acid, digestive juices and food — flow up into the esophagus, causing heartburn.

Acid reflux and GERD occur when contents of the stomach flow up into the esophagus, causing heartburn.

Risk Factors

Most risk factors for acid reflux and GERD are related to lifestyle and are preventable.

Preventable risks for acid reflux:

  • Being overweight or obese
  • Smoking
  • Inhaling second-hand smoke
  • Sedentary lifestyle
  • Drinking too much alcohol
  • Eating too many large, fatty meals
  • Eating large meals too close to bed time

One unpreventable cause of acid reflux is a hiatal hernia. A hiatal hernia causes the upper part of the stomach to move into the chest. This causes the esophageal sphincter to relax and let stomach contents flow up into the esophagus.

Pregnant women also have an increased risk of reflux and GERD because being pregnant increases the pressure in the abdomen.

Some medications such as antidepressants, painkillers, sedatives, blood pressure medications and antihistamines may weaken or relax the esophageal sphincter and lead to reflux.

Diagnosing GERD

A primary health care provider or gastroenterologist — a doctor that specializes in digestive disorders — may recommend a few tests to diagnose GERD.

Upper GI Series

In an upper GI series, the patient swallows a liquid called barium. Then a radiologist takes x-rays of the barium as it travel down the esophagus and into the stomach.

Esophageal Manometry

After using a spray anesthetic on the throat, the health care provider passes a flexible tube in through the nose. The tube travels down the esophagus and into the stomach. It measures the pressure and function of the esophagus.

Esophageal pH

This test is the most accurate for detecting acid reflux, according to the National Institute of Diabetes and Digestive and Kidney Diseases. It monitors the amount of acid that passes into the esophagus when a person is sleeping, eating or performing other activities over a 24-hour period.

A gastroenterologist will place a thin tube through the nose or mouth and into the stomach. The other end attaches to a monitor. It’s removed after 24 hours.

Endoscopy

An endoscopy involves passing a flexible tube with a lighted tip and camera through the mouth, down the esophagus and into the stomach. Health care providers can see abnormalities in the stomach or esophagus, especially if the provider suspects the patient has Barrett’s esophagus. Patients are usually sedated for the procedure. Sometimes the doctor may perform a biopsy and take a small piece of the tissue to examine in the lab.

Complications of GERD

If left untreated, GERD can cause a number of complications. It can cause bleeding and scarring in the esophagus. The most serious complication is an increased risk of esophageal cancer.

Esophagitis

Esophagisits is inflammation of the esophagus. If it persists for many years, it increases the risk for precancerous changes in the esophagus.

Narrowing of the Esophagus

Narrowing of the esophagus or esophageal stricture can lead to problems swallowing.

Barrett’s Esophagus

This condition makes the lining of the esophagus resemble the lining of the intestine. It is more likely to affect adult men. Researchers estimate it affects up to 6.8 percent of people. People with this condition are more likely to get esophageal cancer.

Respiratory Problems

Stomach acid may enter the lungs of people with GERD. It can irritate tissues in the lungs and throat. This can cause wheezing, pneumonia, chest congestion, asthma, and laryngitis.

Treatment

Treatment options for acid reflux and GERD include lifestyle changes, medications, surgery or a combination of these. In cases where symptoms are not too severe, a health care provider may recommend lifestyle changes and over-the-counter acid reducers such as Zantac, Rolaids or Tums.

In more serious cases, treatments may include prescription medications such as proton pump inhibitors including Nexium or Prevacid. If all non-invasive recommendations fail, a patient may consider surgery to strengthen the natural barrier between the stomach and esophagus.

Surgery and proton pump inhibitors scored the highest for suppressing acid, healing esophagitis, managing complications and maintaining remission of acid reflux, according to the American College of Gastroenterology.

According to an article by the Institute for Quality and Efficiency in Health Care in Germany published in the U.S. Library of Medicine, 45 out of 100 people had an improvement in their acid reflux symptoms. In contrast, 14 out of 100 people who took H2 blockers saw improvement.

Medications for Acid Reflux

Drug Class Brand Name (generic)
Antacids Maalox, Mylanta, Riopan, Rolaids
H2 Blockers Tagamet HB (cimetidine), Pepcid AC (famotidine), Axid AR (nizatidine), Zantac (ranitidine)
Proton Pump Inhibitors (PPIs) Nexium (esomeprazole), Prevacid (lansoprazole), Prilosec (omeprazole), Protonix (pantoprazole), AcipHex (rabeprazole)
Prokinetics Urecholine (bethanechol), Reglan (metoclopramide)

Home Remedies for Acid Reflux

A common home remedy recommended for acid reflux is apple cider vinegar, and several people online claim it works. But there is no scientific evidence that supports this claim, Dr. Marcelo Campos wrote in an article for Harvard Medical School.

People who want to try and control acid reflux without medication or surgery are better off trying lifestyle changes.

Natural ways to reduce acid reflux include:

  • Don’t overeat
  • Try not to eat two to three hours before bedtime
  • Wear lose-fitting clothes that don’t squeeze your abdomen
  • If you are overweight, lose some weight
  • Quit smoking
  • Stay upright for 3 hours after meals and don’t slouch or recline when sitting
  • Try raising the head of your bed by six to eight inches to sleep at an incline
  • Avoid foods or drinks that trigger reflux such as high fat or spicy foods, carbonated beverages and alcohol
  • Avoid vigorous exercise right after eating
  • Check medications for any side effects that might increase risk of reflux

Acid Reflux and GERD in Babies

Even children and babies can have acid reflux. Babies with acid reflux usually spit up food. Acid reflux and GERD are common in babies because the valve that separates the stomach from the esophagus isn’t fully developed yet. Once it develops, babies typically stop having reflux.

Symptoms of acid reflux in babies include:

  • Back arching during or right after feeding
  • Coughing
  • Crying lasting for more than 3 hours a day, also called colic
  • Difficulty breathing
  • Infections in the lungs such as pneumonia
  • Irritability after feeding
  • Low weight, weight loss
  • Not wanting to feed
  • Trouble swallowing
  • Vomiting
  • Wheezing while breathing

Treatment for infant reflux typically involves feeding changes, medications and in rare instances, surgery. For the first 3 months of their lives, most babies regurgitate or spit up many times a day. It typically goes away by the time they are one year old. Only 10 percent of babies have GERD after their first birthday.

GERD Diet

There is no official diet for GERD or acid reflux, but most health providers recommend some foods that could help control symptoms.

“Diet plays a major role in controlling acid reflux symptoms and is the first line of therapy used for people with GERD,” according to Dr. Ekta Gupta, a gastroenterologist with Johns Hopkins Medicine.

This list of foods is high in fiber and water and higher on the pH scale (foods high on the scale are less acidic) which may help control acid.

Foods that help control acid reflux:

  • Whole grains
  • Root vegetables
  • Green vegetables
  • Bananas
  • Nuts
  • Fennel
  • Cauliflower
  • Melons
  • Celery
  • Cucumber
  • Lettuce
  • Watermelon
  • Herbal tea
  • Broth-based soups
  • Ginger
