acid reflux on one side

Overview

Acid reflux happens when stomach acid flows back into the tube connecting your mouth and stomach (called the esophagus). This can cause a burning feeling in your chest or throat. Some people notice that this sensation is stronger on one side of their chest or neck. While reflux usually affects the middle of the chest, feeling it more on one side may be due to how you lie down, a hiatal hernia (when part of your stomach pushes up through the diaphragm), or other factors.

Many people with acid reflux notice that symptoms can feel stronger on one side, especially after eating or when lying down. It is a common variation, not a separate condition.

Anyone with acid reflux can experience this, but it may be more noticeable in people with a hiatal hernia, or those who sleep on their side.

Symptoms

Common symptoms

• Burning sensation in the chest (heartburn) that may feel stronger on the left or right side
• Sour taste in the mouth
• Regurgitation of food or liquid
• Feeling of a lump in the throat

Symptoms in children

• Spitting up frequently
• Irritability during or after feeding
• Complaints of chest or stomach pain

Symptoms in older adults

• Chest pain that may be mistaken for heart problems
• Difficulty swallowing
• Chronic cough or hoarseness

Causes

Main causes

• Stomach acid flowing back into the esophagus
• Weakened or relaxed lower esophageal sphincter (the muscle that keeps stomach contents in the stomach)
• Hiatal hernia, where part of the stomach moves into the chest

Risk factors

• Obesity
• Pregnancy
• Smoking
• Large meals or lying down soon after eating
• Certain foods and drinks (such as fatty foods, chocolate, caffeine, alcohol)
• Some medications (like pain relievers)

When to see a doctor

See a doctor urgently if:

• If you have severe chest pain, especially with shortness of breath or pain spreading to your arm
• If you are vomiting blood or have black stools

Book a routine appointment if:

• If heartburn happens more than twice a week
• If symptoms interfere with your daily life
• If over-the-counter antacids do not help

Diagnosis

Your doctor will ask about your symptoms and medical history. They may perform some tests to rule out other conditions.

Tests that may be done

• Endoscopy (a thin tube with a camera is passed down your throat to look at the esophagus and stomach)
• pH monitoring (a test to measure acid levels in the esophagus)
• Barium swallow (X-rays after drinking a chalky liquid)

What to expect at your appointment

Most tests are done as an outpatient. You may be asked to stop taking certain medications beforehand. An endoscopy usually takes about 15-30 minutes and is done with sedation.

Treatment

Treatment aims to reduce acid reflux and protect the esophagus from damage. This includes lifestyle changes, medications that reduce stomach acid (like antacids, H2 blockers, or proton pump inhibitors), and in some cases, surgery.

Self-care at home

• Eat smaller meals more frequently
• Avoid lying down for at least 3 hours after eating
• Sleep with your head elevated about 6 to 8 inches
• Avoid foods and drinks that trigger your symptoms
• Lose weight if you are overweight
• Stop smoking

Medical treatments

Your doctor may recommend medications that help neutralize or reduce stomach acid. These are available over the counter or by prescription. Always follow your doctor's advice. Do not take high doses or for long periods without medical supervision.

When is surgery considered?

Surgery is rarely needed, but may be considered if medications do not work or if you have a large hiatal hernia. The most common procedure is fundoplication, where the top of the stomach is wrapped around the lower esophagus to strengthen the valve.

Living with this condition

Managing acid reflux is often about small adjustments in daily habits. Keep track of what triggers your symptoms and avoid those triggers. Have antacids on hand if needed. If you experience symptoms on one side, try sleeping on your left side, which can reduce reflux because of the way the stomach is positioned.

Lifestyle tips

• Avoid tight clothing around your waist
• Elevate the head of your bed
• Do not eat within 3 hours of bedtime
• Manage stress through relaxation techniques

Diet and exercise

A balanced diet with smaller portions can help. Avoid large, high-fat meals. Exercise is beneficial, but avoid vigorous activity right after eating. Walking after meals may help digestion.

Mental health and emotional wellbeing

Chronic acid reflux can be frustrating and affect your quality of life. The discomfort may cause anxiety, especially if you worry about chest pain. It is important to address these feelings with your doctor or a counsellor.

Prevention

You cannot always prevent acid reflux, but you can reduce how often it happens and how bad it is. Following lifestyle advice and avoiding triggers can make a big difference.

Complications

If left untreated

• Esophagitis (inflammation of the esophagus)
• Esophageal stricture (narrowing of the esophagus due to scarring)
• Barrett's esophagus (changes in the lining of the esophagus that can increase the risk of esophageal cancer)

Long-term outlook

Most people with acid reflux can control their symptoms with lifestyle changes and medications. Even if you have more severe reflux, there are effective treatments. Serious complications are rare. With proper care, you can lead a normal, comfortable life.
