Gastroesophageal reflux disease (GERD) is a digestive disorder that causes stomach acid to flow back up into the esophagus. This is known as acid reflux. The reflux occurs as a result of a malfunction of the lower esophageal sphincter (LES). The LES is the ring of muscles between the esophagus and stomach. Normally, these muscles open to allow food and liquid into the stomach, and then close. In people with GERD, however, the muscles are weak or relax irregularly, allowing stomach contents and acid to creep up into the esophagus and throat.
Acid reflux often causes discomfort and irritation in the esophagus, leading to a sour or bitter taste in the throat and mouth. This is frequently accompanied by heartburn, or a burning sensation in the chest. Some people also experience nausea, coughing, sore throat, dry mouth, and other uncomfortable symptoms.
The prolonged acid reflux associated with GERD can cause inflammation in the esophagus, leading to a condition called esophagitis. Esophagitis may make it difficult or painful to swallow. When left untreated, GERD can also damage your esophageal lining and cause esophageal ulcers and irritation. This may result in bleeding, narrowing of the esophagus, or Barrett’s esophagus, a condition in which the cells lining your esophagus change to ones resembling your intestine. It can be associated with esophageal cancer.
While there are many medical treatments for GERD, changing your diet is one of the easiest and most affordable ways to manage symptoms. It can also help prevent acid reflux from happening in the first place.
What Makes a GERD-Friendly Diet
Certain foods are harder to digest and can increase the amount of acid in the stomach, leading to acid reflux and other GERD symptoms. The types of food that trigger these symptoms can vary from person to person, but common culprits include alcohol, high-fat foods, and spicy foods. It’s important to avoid all foods and drinks that are known to cause discomfort. It also helps to incorporate foods that can ease or prevent GERD symptoms.
What to Avoid Entirely
Avoiding large meals is one of the easiest ways to lower the chances of experiencing acid reflux and heartburn. This means eating five to six small meals a day instead of two or three large ones. It’s also a good idea to avoid eating at least three hours before bedtime.
Although GERD triggers vary in each person, during your meals, make sure to avoid the following:
- soda and other carbonated beverages
- spicy foods
- fried foods
These foods and beverages are known to aggravate GERD symptoms.
What to Limit
Certain foods and drinks are OK to consume in moderation, but they may cause increased discomfort in some people more than others. Here are some foods and beverages that may trigger GERD symptoms and are therefore best consumed in small amounts:
