What is GERD?

Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid backflows into the esophagus. The esophagus is the tube that connects the mouth and stomach. GERD is a chronic and severe form of acid reflux that occurs at least twice per week or has a duration of weeks to months with each occurrence.

Progression

GERD has four stages, each with different symptoms and treatment options. Determining the stage is essential in receiving the most effective treatment. Stages of GERD are determined by severity and frequency.

Stage 1: Mild

The first stage of GERD is typically characterized by chest pain, heartburn, lump sensation in the back of the throat, and infrequent regurgitation (less than once per week). The lower esophagus may become slightly inflamed. The main treatment for mild GERD is lifestyle adjustments, such as avoiding spicy foods and alcohol, decreasing or quitting tobacco use, abstaining from food three hours before bed, and sleeping with an elevated head. Over-the-counter antacids are also beneficial.

Stage 2: Moderate

The second stage of GERD presents the same symptoms as the first stage; however, symptoms occur several times a week and result in significant esophageal inflammation. The symptoms do not respond to over-the-counter antacids and may require a prescription for an H-2 blocker or proton pump inhibitor.

Stage 3: Severe

In addition to the symptoms experienced with mild to moderate GERD, severe GERD may cause a chronic cough, sore throat, and hoarse voice. These symptoms frequently occur numerous times each week or on a daily basis. Because severe GERD is typically unresponsive to medications, a GERD specialist should be consulted to devise a treatment plan. Advanced testing and pH studies are usually needed.

Stage 4: Complications

The fourth stage of GERD indicates other possible complications are present. In addition to the above symptoms, food may also get stuck in the esophagus while eating (dysphagia). If this stage of GERD is suspected, seek immediate care from a GERD specialist. Lifestyle changes and daily medication are often needed. Treatment may also involve surgery or cancer treatment, if applicable.

Possible complications

GERD may present various complications, especially if left untreated. Stomach acid that backflows can cause damage to the esophagus and teeth. Potential complications of GERD include the following:

  • Esophagitis occurs when the lining of the esophagus becomes irritated and inflamed. Esophagus bleeding and ulcers may also develop, which can cause difficulty swallowing.
  • Esophageal strictures result from stomach acid causing scar tissue to form on the lower esophagus. Difficulty swallowing ensues due to narrowing of the esophagus.
  • Barrett’s esophagus involves tissue changes in the lining of the lower esophagus when it is regularly exposed to stomach acid. These changes increase the risk of developing esophageal cancer. If diagnosed early, abnormal cells can be removed.
  • Esophageal cancer may develop as a result of prolonged and repetitive exposure to stomach acid. Symptoms may not appear until late stages; therefore, regular endoscopies are needed for early diagnosis.
  • Tooth decay can occur due to steady exposure to stomach acid. As the acid breaks down tooth enamel, the teeth become weak, which leads to cavities.
