GERD is frequent or troublesome reflux that can cause heartburn, regurgitation, cough, and progressive complications like Barrett's esophagus. Risk factors include obesity, hiatal hernia, pregnancy, smoking, alcohol, and trigger foods. Start with lifestyle changes and OTC medicines; use H2 blockers or PPIs for persistent symptoms. Refer to a gastroenterologist if alarm signs appear or symptoms do not improve; surgical options exist for refractory cases.
What is acid reflux (GERD)?
Gastroesophageal reflux disease (GERD), commonly called acid reflux, occurs when stomach contents flow back into the esophagus and cause symptoms or complications. Many people have occasional heartburn; GERD describes frequent or troublesome reflux that requires attention.
Common risk factors
Several factors increase the likelihood of developing GERD. Obesity and central (abdominal) fat raise intra-abdominal pressure and are among the strongest modifiable risks. Hiatal hernia, pregnancy, and delayed stomach emptying also contribute.
Smoking and excess alcohol use weaken the lower esophageal sphincter and worsen reflux. Certain medications (some calcium channel blockers, nitrates, and others) and a family history may play a role. Diet and lifestyle - large meals, late-night eating, and trigger foods such as high-fat or very spicy foods, chocolate, caffeine, and mint - can aggravate symptoms.
Typical symptoms and warning signs
The classic symptoms are heartburn (a burning sensation behind the breastbone) and regurgitation of sour or bitter fluid. Other common complaints include chest discomfort, chronic cough, hoarseness, throat clearing, a sensation of a lump in the throat, difficulty swallowing, and dental enamel erosion.
Seek prompt evaluation for alarm signs: difficulty swallowing (progressive), unintended weight loss, gastrointestinal bleeding, recurrent vomiting, or new-onset severe chest pain. These symptoms may need endoscopy or urgent care.
Short-term and long-term consequences
Untreated chronic reflux can cause inflammation (esophagitis), scarring and strictures, and changes in the lining of the lower esophagus called Barrett's esophagus. Barrett's increases the long-term risk of esophageal adenocarcinoma, so surveillance strategies are recommended when Barrett's is present.
Practical treatment approach
Start with lifestyle measures that reduce reflux and improve symptoms:
- Lose weight if overweight and avoid tight clothing around the waist.
- Elevate the head of the bed 6-8 inches and avoid lying down for 2-3 hours after eating.
- Eat smaller, more frequent meals and identify individual trigger foods.
- Stop smoking and limit alcohol.
Refer to a gastroenterologist if symptoms persist despite therapy, if alarm features develop, or if long-term surveillance for Barrett's is needed. When medical therapy fails or is not preferred, surgical options - laparoscopic fundoplication or magnetic sphincter augmentation (LINX device) - can restore the barrier to reflux.
Practical takeaway
Most people get meaningful relief by combining targeted lifestyle changes with appropriate medication under medical guidance. Persistent or severe symptoms warrant specialist evaluation to prevent complications.
