GERD Awareness

Gastroesophageal reflux disease (GERD) is a chronic digestive disorder where stomach acid or bile irritates the lining of the esophagus. This backwash of acid can cause a variety of symptoms and, if left untreated, can lead to more serious health problems. Understanding the causes and symptoms of GERD is essential for effective management and treatment.

The causes of GERD can be multifaceted, often involving a combination of lifestyle factors and anatomical issues. Common triggers include consuming large meals or lying down right after eating, being overweight or obese, smoking, and certain dietary choices such as spicy or fatty foods, caffeine, and alcohol. Additionally, a weakened lower esophageal sphincter (LES) – the muscle that separates the esophagus from the stomach – can fail to close properly, allowing acid to escape into the esophagus. Other contributing factors might include pregnancy, which increases abdominal pressure, and hiatal hernia, where a part of the stomach pushes through the diaphragm.

Causes of GERD

GERD occurs when stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus. Several factors can contribute to GERD:

Dysfunction of the Lower Esophageal Sphincter (LES)

  • Weak LES: The LES is a ring of muscle at the entrance to the stomach. It acts as a valve, opening to let food in and closing to prevent stomach acids from escaping. If the LES weakens or relaxes abnormally, acid can flow back into the esophagus, causing GERD.
  • Hiatal Hernia: This condition occurs when the upper part of the stomach moves above the diaphragm, which normally helps keep acid in the stomach. A hiatal hernia can weaken the LES and increase the risk of GERD.

Lifestyle and Dietary Factors

  • Obesity: Excess body weight increases pressure on the abdomen, pushing up the stomach and causing acid to back up into the esophagus.
  • Diet: Consuming large meals or lying down right after eating can trigger reflux. Certain foods and drinks, including fatty foods, chocolate, caffeine, alcohol, and spicy foods, can also cause GERD symptoms.
  • Smoking: Tobacco use can weaken the LES and increase acid production.
  • Pregnancy: Hormonal changes during pregnancy can cause the LES to relax, and the growing fetus can increase pressure on the stomach, leading to acid reflux.
  • Certain Medications: Drugs such as aspirin, ibuprofen, certain muscle relaxers, and blood pressure medications can increase the risk of GERD.

Other Contributing Factors

  • Delayed Stomach Emptying: Gastroparesis, a condition in which the stomach takes longer to empty, can cause increased stomach pressure and reflux.
  • Connective Tissue Disorders: Conditions such as scleroderma can cause GERD by affecting the esophagus and LES.

Symptoms of GERD

GERD symptoms can vary in severity and frequency, but common signs include:


  • Burning Sensation in the Chest: This is the most common symptom of GERD. It usually starts behind the breastbone and can move up to the throat. The sensation can last from a few minutes to several hours and is often worse after eating or when lying down.


  • Sour or Bitter-Tasting Acid: Acid backing up into your throat or mouth can leave a sour or bitter taste.

Difficulty Swallowing (Dysphagia)

  • Sensation of Food Being Stuck: The narrowing of the esophagus due to acid damage can cause pain and make swallowing difficult.

Chronic Cough and Sore Throat

  • Irritation from Acid: Acid reflux can irritate the throat and larynx, leading to a persistent cough or a sore throat.

Hoarseness or Laryngitis

  • Damage to Vocal Cords: Repeated exposure to stomach acid can damage the vocal cords, causing hoarseness or laryngitis.

Lump in Throat

  • Globus Sensation: A persistent sensation of a lump in the throat.

Nausea and Vomiting

  • Digestive Symptoms: Especially after meals, can be a sign of GERD.

When to See a Doctor

While occasional heartburn is common and can often be managed with lifestyle changes and over-the-counter medications, frequent or severe symptoms may indicate a more serious condition, such as gastroesophageal reflux disease (GERD). It's important to see a healthcare provider if you:

  • Experience heartburn more than twice a week.
  • Find that over-the-counter medications do not provide relief.
  • Have difficulty swallowing or persistent nausea and vomiting.
  • Notice unexplained weight loss or loss of appetite.
  • Experience severe chest pain, especially if combined with other symptoms like shortness of breath or pain in the arm or jaw, as these could be signs of a heart attack.


GERD is a common and often chronic condition that can significantly impact quality of life. Understanding its symptoms and causes is the first step in managing the condition effectively. Lifestyle changes, dietary adjustments, and medications are commonly used to manage GERD symptoms. If you experience frequent or severe symptoms of GERD, it is important to consult with a healthcare provider to develop an appropriate treatment plan and prevent potential complications.
