GERD (Acid Reflux) and Acidity: Symptoms, Causes, Treatment & Prevention

What Is GERD?

GERD, or gastroesophageal reflux disease, is a condition in which stomach contents repeatedly flow back into the esophagus and cause troublesome symptoms or complications.

Normally, the lower esophageal sphincter—a muscular valve between the esophagus and stomach—helps prevent stomach contents from flowing backward. If this barrier does not function properly, stomach contents can move back into the esophagus, resulting in reflux symptoms.

The terms acid reflux, acid regurgitation, heartburn and acidity are often used interchangeably in everyday conversation. However, medically they can describe somewhat different symptoms or conditions. Heartburn, for example, refers specifically to a burning sensation behind the breastbone, while GERD is a chronic condition associated with recurrent reflux.

What Are the Symptoms of GERD and Acid Reflux?

GERD does not affect everyone in exactly the same way. Common GERD symptoms and acid reflux symptoms may include:

• A burning sensation in the chest, commonly called heartburn
• Sour or acidic taste in the mouth
• Regurgitation of food or stomach contents
• Upper abdominal or chest discomfort
• Difficulty or pain while swallowing
• A sensation of a lump in the throat
• Nausea in some people
• Chronic cough or throat symptoms, particularly with nighttime reflux
• Hoarseness or voice changes in some cases

Symptoms may become more noticeable after eating, when bending over, or when lying down. Acid reflux at night can also disturb sleep.

What Causes Acid Reflux and GERD?

Acid reflux occurs when stomach contents move backward into the esophagus. GERD can develop when this reflux happens repeatedly and causes persistent symptoms or complications.

1. Weak or Inappropriately Relaxing Lower Esophageal Sphincter

The lower esophageal sphincter normally acts as a barrier between the stomach and esophagus. If it becomes weak or relaxes at inappropriate times, reflux can occur.

2. Hiatal Hernia

A hiatal hernia occurs when part of the stomach moves upward through the diaphragm. It can increase the likelihood of GERD or make reflux symptoms worse.

3. Being Overweight or Having Obesity

Excess body weight can increase the risk of GERD. For people who are overweight or have obesity, appropriate weight reduction may help improve reflux symptoms.

4. Large or Late Meals

Eating large meals or eating close to bedtime may aggravate reflux symptoms in some people. Avoiding food for about three hours before lying down may help people who experience nighttime symptoms.

5. Certain Foods and Beverages

Different people have different triggers. Foods and drinks that may worsen symptoms in some individuals include:

• High-fat or fried foods
• Spicy foods
• Chocolate
• Mint
• Coffee and other caffeinated beverages
• Alcohol
• Citrus fruits
• Tomato-based foods
• Carbonated beverages in some individuals

It is not necessary for every person with GERD to avoid all of these foods. Identifying your own triggers is generally more practical.

Acidity vs GERD: Are They the Same?

Not necessarily.

Occasional acidity or heartburn can occur from time to time and does not automatically mean that a person has GERD.

GERD is a chronic condition involving recurrent reflux that causes troublesome symptoms or complications.

If heartburn or reflux symptoms are frequent, persistent, interfere with daily activities or continue despite lifestyle changes and over-the-counter treatment, medical evaluation is appropriate.

What Can Trigger GERD Symptoms?

Triggers vary from person to person, but common factors include:

• Heavy meals
• Eating late at night
• Lying down soon after eating
• Fatty or fried foods
• Spicy foods
• Certain acidic foods
• Coffee or other caffeinated drinks
• Alcohol
• Smoking
• Excess body weight

Keeping a simple food and symptom diary can help identify individual triggers and patterns.

GERD and Acidity at Night

Acid reflux may become particularly troublesome at night, especially when symptoms occur after lying down.

Some measures that may help include:

• Finish meals at least three hours before going to bed.
• Avoid foods or beverages that consistently trigger your symptoms.
• If you are overweight, discuss healthy weight management with your doctor.
• Your doctor may recommend elevating the upper body during sleep in appropriate cases.

Persistent nighttime symptoms should not simply be ignored, particularly when they regularly disturb sleep.

What Foods Should You Avoid in GERD?

There is no single GERD diet that works identically for everyone. Certain foods commonly associated with reflux symptoms include high-fat foods, spicy foods, chocolate, mint, coffee, alcohol, citrus and tomato products.

Instead of unnecessarily eliminating many foods, consider identifying foods that consistently trigger your own symptoms.

A Practical Approach to GERD Diet

• Eat smaller meals.
• Avoid very heavy meals.
• Limit your personal trigger foods.
• Avoid meals close to bedtime.
• Maintain a healthy body weight when appropriate.
• Stay adequately hydrated.
• Follow an individualized dietary plan if symptoms persist.

How Is GERD Diagnosed?

In many cases, doctors can initially diagnose GERD by reviewing a person's symptoms and medical history. If symptoms do not improve with appropriate treatment, or if complications or another condition are suspected, additional testing may be recommended.

Upper GI Endoscopy

An upper gastrointestinal endoscopy allows the doctor to examine the lining of the esophagus, stomach and duodenum using a flexible camera.

It may help identify inflammation, narrowing, other abnormalities or complications associated with reflux.

Other Tests

Depending on the patient's symptoms and clinical situation, a gastroenterologist may consider additional investigations to assess reflux or evaluate other possible causes of symptoms.

The appropriate test depends on the individual patient rather than being the same for everyone.

How Is GERD Treated?

Acid reflux treatment and GERD management depend on the severity of symptoms, underlying factors and whether complications are present.

Lifestyle Changes

Lifestyle measures may form an important part of GERD management. Depending on the individual, a doctor may recommend:

• Weight reduction if overweight or living with obesity
• Avoiding meals close to bedtime
• Identifying and limiting foods that trigger symptoms
• Quitting smoking
• Modifying eating habits
• Elevating the head and upper body during sleep when appropriate

Medicines

Doctors may use different types of medicines depending on the patient's symptoms.

• Antacids: May provide short-term relief for mild symptoms.
• H2-receptor blockers: Reduce stomach acid production.
• Proton pump inhibitors (PPIs): Reduce stomach acid production and are commonly used in the treatment of GERD. They can also help heal an irritated esophageal lining.

Medication should be taken according to medical advice, particularly when symptoms are frequent or treatment is needed for an extended period.

If symptoms persist despite appropriate treatment, a gastroenterologist may reassess the diagnosis, treatment plan and need for further investigations.

Procedures or Surgery

In selected patients whose symptoms do not respond adequately to medical and lifestyle treatment, or in certain other circumstances, procedures or surgery may be considered. Fundoplication is one surgical treatment used for GERD.

The suitability of any procedure depends on an individual's symptoms, investigations and overall health.

Can GERD Cause Complications?

Long-standing, inadequately controlled GERD can sometimes lead to complications.

Potential complications include:

• Esophagitis, or inflammation of the esophagus
• Esophageal ulcers or bleeding
• Esophageal stricture, which can cause difficulty swallowing
• Barrett's esophagus, a change in the lining of the lower esophagus associated with an increased risk of esophageal cancer

These complications do not occur in everyone with GERD. Appropriate evaluation and treatment can help manage symptoms and address complications when they occur.

When Should You See a Gastroenterologist for Acidity?

Occasional heartburn may not require extensive medical evaluation. However, you should consider consulting a doctor if:

• Heartburn or reflux happens frequently.
• Symptoms continue despite lifestyle changes.
• You regularly need nonprescription medicines for heartburn.
• Symptoms interfere with your daily life or sleep.
• You have difficulty or pain while swallowing.
• You have persistent nausea or vomiting.
• You experience unexplained weight loss.
• You have symptoms suggesting gastrointestinal bleeding.

Frequently Asked Questions About GERD and Acidity

Takeaway
