Gastroesophageal reflux disease (GERD)

At some point of your life, you must have experienced sour or bitter taste in your mouth after having food. This is due to acid reflux. If this occurs for a prolonged period, it is known as chronic acid reflux or gastroesophageal reflux disease (GERD). It is a condition in which acid juices in your stomach flow up back into the oesophagus (tube from throat to stomach).

The prevalence of GERD in India ranges from 7.6% to 30%. Less than 10% of GERD patients in India have erosive esophagitis.

When food reaches your stomach, a valve at the end of your oesophagus called the lower oesophageal sphincter fails to seal properly, causing acid reflux. Acidic fluids then travel up your oesophagus, through your throat, and into your mouth, leaving you with a sour taste. Acid reflux affects many people and occurs regularly in some people.

Symptoms of GERD:

The main symptom of chronic acid reflux is heart burn (acid indigestion). You may feel like having a chest pain starting from your breastbone and moving to your neck and throat, leaving an acid or bitter taste in your mouth.

Besides pain, you may also experience:

Difficulty or pain
while swallowing

Acid regurgitation
(re-tasting your food after eating)

Sore throat

Chronic cough

Disrupted sleep

(inflammation to your voice box)


Loss of appetite

Blood vomits or stools

Causes of GERD:

GERD can be caused by a variety of factors that influence your lower oesophageal sphincter.

  • Pregnancy (experience heartburn regularly due to increased pressure)
  • Overweight or obesity
  • Taking certain medications can make your symptoms worse (asthma, high blood pressure and allergies, painkillers, and anti-depressants).
  • Eating dairy, spicy or fried foods
  • Smoking
  • Hiatal hernia (condition in which the opening in your diaphragm lets the upper part of the stomach move up into your chest).

Diagnosis and treatment:

Diagnosis of GERD is based on the physical examination and your history of signs and symptoms. Your doctor may recommend endoscopy, X-rays or ambulatory acid probe tests.

Lifestyle and the dietary changes are the first step in treating GRED. For example, avoiding foods that increase acid levels, avoid large meals and fatty foods, etc.

Your doctor may prescribe you some medications if lifestyle and dietary changes doesn’t work. Medications like antacids, proton pump inhibitors, etc. are recommended to decrease acid production. If lifestyle and medications doesn’t work or you are unable to take drugs for an extended period of time, surgery may be an option to relieve the symptoms.

FAQ's :

Genetics along with environmental factors play a role in causing acid reflux. According to studies, genetic contribution seems to play a crucial role in the development of GERD and GERD-related diseases and it has also shown some percent of heritability.

Individuals having a family history of gastrointestinal issues are at high risk. Obesity has been linked to a six-fold increase in the risk of GERD. Other risk factors include smoking, pregnancy, hiatal hernia, heavy alcohol intake.

Genetics is widely used to address the underlying disease mechanisms and provide potential new targets for personalised drug treatments and biomarkers for patient stratification.

Yes, avoiding certain foods like caffeinated beverages, alcohol, acid liquids, spicy and fatty foods can reduce your symptoms. Quitting smoking and avoiding laying down immediately after having your meals may also help improve your condition.
