Acid regurgitation

Overview

Acid regurgitation is when stomach acid flows back up into your throat or mouth, often causing a sour or bitter taste. It is a common symptom of heartburn or acid reflux.

Yes, it is very common. Many adults experience it now and then, especially after large or spicy meals.

It can affect people of all ages, but is more common in older adults, pregnant women, and people who are overweight.

Symptoms

Common symptoms

• A burning feeling in your chest (heartburn), often after eating or at night.
• Sour or bitter taste in your mouth.
• Feeling like food or liquid is coming back up into your throat.
• Coughing or hoarseness, especially in the morning.

Symptoms in children

• Spitting up or vomiting often.
• Irritability or crying during or after feeding.
• Coughing or wheezing, especially at night.
• Poor appetite or trouble gaining weight.

Symptoms in older adults

• Less obvious heartburn; instead, they may have a chronic cough or hoarseness.
• Difficulty swallowing or feeling like food is stuck.
• Chest pain that is not related to the heart.

Causes

Main causes

• A weak or relaxed muscle between the stomach and food pipe (lower esophageal sphincter).
• A hiatal hernia, when part of the stomach moves up into the chest.
• Eating large meals or lying down right after eating.
• Certain foods and drinks, like spicy, fatty, or acidic foods, caffeine, and alcohol.

Risk factors

• Being overweight or obese.
• Pregnancy.
• Smoking or exposure to secondhand smoke.
• Taking some medicines (ask your doctor or pharmacist).
• Stress and lack of sleep.

When to see a doctor

See a doctor urgently if:

• If you have chest pain that feels different from your usual heartburn – especially with shortness of breath or sweating.
• If you have trouble swallowing or pain with swallowing.
• If you vomit blood or have black stools.

Book a routine appointment if:

• Heartburn that happens more than twice a week.
• Symptoms that keep coming back despite using antacids or lifestyle changes.
• Persistent cough, hoarseness, or asthma symptoms that are not getting better.

Diagnosis

Your doctor will ask about your symptoms and medical history. They may also perform a physical exam. If your symptoms are frequent or severe, they might refer you to a specialist.

Tests that may be done

• Endoscopy – a thin tube with a camera is passed down your throat to look at your food pipe and stomach.
• pH monitoring – a test that measures acid levels in your food pipe over 24 hours.
• Barium swallow – you drink a chalky liquid that shows up on X-rays to see the shape of your digestive tract.

What to expect at your appointment

Your doctor will first try to rule out more serious causes. The tests are usually done in a hospital or clinic and are not painful, though an endoscopy may require sedation. Most people get a clear diagnosis after a few simple tests.

Treatment

Treatment focuses on reducing the amount of acid coming back up and protecting your food pipe from damage. Often, lifestyle changes and over-the-counter medicines are enough. For persistent cases, your doctor may recommend stronger prescription treatments.

Self-care at home

• Eat smaller, more frequent meals rather than large ones.
• Avoid lying down for at least two to three hours after eating.
• Raise the head of your bed by 15 to 20 centimetres (6 to 8 inches).
• Avoid foods and drinks that trigger your symptoms (like spicy dishes, citrus, fatty foods, alcohol, and coffee).
• Lose weight if you are overweight.
• Stop smoking.

Medical treatments

For mild symptoms, you can try antacids (which neutralise acid) or alginates (which form a barrier on top of your stomach contents). For more persistent symptoms, doctors may recommend medicines that reduce acid production, such as H2 blockers or proton pump inhibitors. These are available over the counter or on prescription. Always talk to your doctor or pharmacist before starting any new medicine.

When is surgery considered?

A small number of people with severe acid regurgitation that does not get better with medicines may need a procedure called fundoplication. This involves tightening the muscle at the bottom of the food pipe. Your doctor will discuss if this is an option for you.

Living with this condition

Most people with acid regurgitation can manage their symptoms well with simple changes to their diet and habits. It may take a few weeks to find what works best for you.

Lifestyle tips

• Avoid tight clothing that puts pressure on your stomach.
• Try to eat at least three hours before bedtime.
• Chew gum after meals – this can help neutralise acid and increase saliva.
• Manage stress with relaxation techniques like deep breathing or gentle exercise.

Diet and exercise

Eat a balanced diet with plenty of vegetables, lean protein, and whole grains. Avoid high-fat or very spicy foods. Regular exercise like walking can help you keep a healthy weight, but avoid heavy exercise right after meals. Wait at least an hour before working out.

Mental health and emotional wellbeing

Living with chronic acid reflux can be frustrating and may cause anxiety or disrupt sleep. If your symptoms are making you feel stressed or down, talk to your doctor. They can offer support and suggest ways to cope.

Prevention

You cannot always prevent acid regurgitation, but you can reduce how often it happens. Staying at a healthy weight, avoiding known trigger foods, and not lying down right after meals are the best ways to lower your risk.

Complications

If left untreated

• Esophagitis – inflammation and damage to the lining of the food pipe.
• Barrett's esophagus – changes in the cells of the food pipe that can increase the risk of cancer.
• Strictures – narrowing of the food pipe that makes swallowing difficult.
• Respiratory problems like asthma, chronic cough, or pneumonia from acid getting into the lungs.

Long-term outlook

With proper treatment and lifestyle changes, most people with acid regurgitation can control their symptoms and avoid serious problems. Severe complications are uncommon, especially when the condition is managed early. Your doctor will help you find a plan that works for you.
