GERD (Acid Reflux): Symptoms, Causes, and Treatment

GERD is a chronic condition where stomach acid flows back into your esophagus, causing irritation. Symptoms include frequent heartburn, regurgitation, and trouble swallowing. It's often caused by a weakened lower esophageal sphincter (LES). While there's no cure, symptoms can be managed with medications and lifestyle changes. See your doctor if you have symptoms more than twice a week.

In plain words

GERD is when stomach acid often flows back into your food pipe. This can irritate it. You might feel heartburn, taste sour or bitter spit, or have trouble swallowing. It happens when the muscle at the bottom of your food pipe doesn't close right. You can't cure GERD, but medicine and changing some habits can help. See a doctor if you have symptoms more than two times a week.

Symptoms

Early symptoms

  • Heartburn: A burning sensation in your chest, often after eating, that may worsen at night or when lying down. (1) (3)
  • Regurgitation: A sour or bitter taste in your mouth from acid backing up into your throat or mouth. (1) (2)
  • Difficulty swallowing: Feeling like food is stuck in your throat or chest, especially with dry or dense foods. (3) (2)
  • Chronic cough: A persistent dry cough that may worsen at night or after meals, unrelated to a cold. (3)
  • Disrupted sleep: Frequent nighttime awakenings due to heartburn, coughing, or throat irritation. (3)

Serious or emergency symptoms

  • Severe chest pain: Intense pain that may mimic a heart attack, sometimes spreading to jaw or arms. Seek emergency care immediately to rule out heart problems. (3)
  • Persistent vomiting or vomiting blood: May indicate bleeding or severe irritation in the esophagus. Seek emergency medical attention right away. (3)
  • Black, tarry stools: Can be a sign of bleeding in the digestive tract from acid damage. Contact your doctor immediately. (3)
  • Unintentional weight loss: May indicate complications like esophageal narrowing or another serious condition. See your doctor as soon as possible. (6)

Causes

Primary causes

  • Weak lower esophageal sphincter (LES): Normally closes after food passes through to the stomach. When weak or relaxing abnormally, it lets stomach contents flow back up. (3) (2)
  • Hiatal hernia: When part of the stomach pushes up through the diaphragm, affecting how the LES works. (3)
  • Delayed stomach emptying: Food stays in the stomach longer, increasing pressure and chance of reflux. (3)

Risk factors

Obesity

Excess weight puts pressure on the abdomen, pushing stomach contents upward. (3)

Pregnancy

Hormonal changes and pressure from the growing uterus can contribute to reflux. (3)

Smoking

Damages the LES and reduces saliva production that helps neutralize acid. (3)

Certain medications

Some blood pressure drugs, sedatives, and painkillers may relax the LES or irritate the esophagus. (3)

Diagnosis

Doctors typically diagnose GERD based on your symptoms and response to treatment. If symptoms persist despite treatment or are severe, tests like an endoscopy (using a flexible tube to view the esophagus), pH monitoring (measuring acid levels), or a barium swallow X-ray may be recommended to check for complications or other conditions.

Upper endoscopy

Allows your doctor to examine your esophagus and stomach for damage or abnormalities. (4)

Ambulatory acid (pH) probe test

Measures acid levels in your esophagus over 24-48 hours to identify reflux episodes. (4)

Esophageal manometry

Measures muscle contractions in your esophagus to assess how well it moves food. (4)

Barium swallow

X-ray of your upper digestive tract after drinking a chalky liquid that coats the esophagus. (4)

Treatment

Medication options

Proton pump inhibitors (PPIs)

Reduce stomach acid production by blocking the enzyme system in acid-producing cells. (2) (5)

H2 receptor blockers

Decrease acid production by blocking histamine, which triggers acid release. (2)

Antacids

Neutralize stomach acid quickly for temporary relief but don't prevent or heal damage. (2) (5)

Lifestyle and self-care

  • Diet modifications: Avoid trigger foods like fatty/fried foods, chocolate, caffeine, alcohol, spicy foods, citrus, and carbonated drinks that can relax the LES or increase acid. (1) (7)
  • Meal timing and size: Eat smaller, more frequent meals instead of large ones. Avoid eating within 2-3 hours of bedtime. (1) (5)
  • Weight management: Losing excess weight can reduce pressure on your abdomen and decrease symptoms. (5)
  • Head-of-bed elevation: Raise the head of your bed 6-8 inches with blocks or use a wedge pillow to use gravity to prevent nighttime reflux. (5)

Always discuss dosing and treatment changes with your own prescriber.

Possible complications

  • Esophagitis: Inflammation that can damage the esophagus lining, potentially causing bleeding or ulcers. (6)
  • Esophageal stricture: Narrowing of the esophagus from scar tissue, making swallowing difficult and painful. (6)
  • Barrett's esophagus: Pre-cancerous changes to esophageal tissue that slightly increase cancer risk. (6)
  • Respiratory problems: Chronic irritation can trigger asthma, chronic cough, or worsen existing lung disease. (6)

When to see a doctor

Routine follow-up

  • Schedule an appointment if you experience heartburn or other GERD symptoms more than twice weekly despite lifestyle changes and over-the-counter medications. (4)
  • See your doctor if symptoms interfere with your sleep or daily activities, or if you're using antacids regularly for more than two weeks. (6)

Seek emergency care

  • Seek immediate medical care if you experience severe chest pain, especially if accompanied by arm or jaw pain, which could indicate a heart attack. (4) (6)
  • Get emergency help if you vomit blood, notice black/tarry stools, or experience persistent difficulty swallowing or unintentional weight loss. (6)

Frequently asked questions

What is GERD?

GERD (gastroesophageal reflux disease) is a chronic condition where stomach acid frequently flows back into the esophagus, causing irritation. Unlike occasional heartburn, GERD occurs at least twice weekly and can lead to complications if untreated. (8)

What are the first signs of GERD?

The most common early symptoms are frequent heartburn (burning chest discomfort), regurgitation (sour/bitter taste in mouth), and difficulty swallowing. Nighttime symptoms like disrupted sleep or chronic cough may also develop. (7)

What causes GERD?

GERD is mainly caused by a weakened lower esophageal sphincter (the valve between your stomach and esophagus) that doesn't close properly, allowing acid to flow back up. Other factors include hiatal hernia, delayed stomach emptying, certain foods, obesity, and pregnancy. (8)

How is GERD treated?

Treatment combines lifestyle changes (diet, weight loss, meal timing) with medications (PPIs, H2 blockers, antacids). In severe cases, surgery may be considered. Work with your doctor to find the best approach for your symptoms. (8)

Can GERD be cured?

While GERD is usually a chronic condition, symptoms can often be effectively managed with the right treatment plan. Some people achieve long-term control of symptoms through consistent lifestyle changes and medications as needed. (7)
