Heartburn sensation

Overview

Heartburn is a burning feeling in your chest, just behind your breastbone. It happens when stomach acid flows back into your esophagus (the tube that connects your mouth to your stomach). This is sometimes called acid reflux.

Yes, heartburn is very common. Most people experience it from time to time.

Anyone can get heartburn, but it is more common in adults, people who are pregnant, people who are overweight, and those who smoke or drink alcohol regularly.

Symptoms

Common symptoms

• A burning pain in the chest, often after eating, at night, or when lying down or bending over.
• A sour or bitter taste in your mouth.
• Regurgitation – food or liquid coming back up into your mouth.

Symptoms in children

• Children may feel the same burning pain, but they might have trouble explaining it. They may also spit up more, seem fussy after meals, or be reluctant to eat.

Symptoms in older adults

• Older adults may have less typical symptoms, such as a chronic cough, hoarseness, a feeling of a lump in the throat, or nausea. Chest pain may be less intense.

Causes

Main causes

• A weak or relaxed valve between your esophagus and stomach (lower esophageal sphincter) allows stomach acid to flow backward.
• A hiatal hernia – where part of your stomach pushes upward into your chest.
• Certain foods and drinks that can trigger acid reflux.

Risk factors

• Eating large meals or eating close to bedtime.
• Being overweight or obese.
• Pregnancy.
• Smoking or exposure to secondhand smoke.
• Drinking alcohol, coffee, or carbonated drinks.
• Eating fatty, spicy, or acidic foods (like citrus, tomatoes, chocolate, or onions).
• Certain medications (for example, some asthma drugs, pain relievers, or blood pressure medications).

When to see a doctor

See a doctor urgently if:

• If you have chest pain that feels different from your usual heartburn – especially if it comes on with exertion or stress.
• If you have trouble swallowing or pain when swallowing.
• If you vomit blood or have black stools.

Book a routine appointment if:

• If you have heartburn more than twice a week.
• If you need to use over-the-counter heartburn remedies more than twice a week.
• If your symptoms wake you up at night.
• If you have had heartburn for a long time or it is affecting your daily life.

Diagnosis

Your doctor will ask about your symptoms, diet, and lifestyle. They may also feel your abdomen and check your general health. Most people with heartburn do not need tests, but your doctor may recommend some if symptoms are severe or long-lasting.

Tests that may be done

• Endoscopy – a thin, flexible tube with a camera is passed down your throat to look at your esophagus and stomach.
• pH monitoring – a test that measures acid levels in your esophagus over 24 hours.
• Barium swallow – you drink a chalky liquid that shows up on X-rays, helping your doctor see if you have a hiatal hernia or other problems.

What to expect at your appointment

Your doctor will first listen to your story and may suggest lifestyle changes. If tests are needed, they will explain what to expect. Endoscopy is usually done with a mild sedative, and you can go home the same day.

Treatment

Treatment for heartburn starts with lifestyle changes. If those are not enough, your doctor may recommend medications to reduce stomach acid or help your stomach empty faster. Surgery is rarely needed.

Self-care at home

• Eat smaller, more frequent meals instead of large ones.
• Avoid eating within 2–3 hours before lying down or going to bed.
• Raise the head of your bed by 6–8 inches (use blocks or a wedge pillow).
• Avoid foods and drinks that trigger your heartburn – common triggers include fatty foods, spicy foods, citrus, chocolate, caffeine, alcohol, and carbonated drinks.
• Lose weight if you are overweight.
• Stop smoking.
• Wear loose clothing around your waist.

Medical treatments

If lifestyle changes are not enough, your doctor may recommend medications. These include medicines that neutralize stomach acid (antacids), reduce acid production, or help your stomach empty faster. Some are available over the counter, others by prescription. Always follow your doctor or pharmacist's advice. Do not take any medication for longer than recommended without talking to your doctor.

When is surgery considered?

Surgery is an option only for people with severe, long-term heartburn that does not get better with lifestyle changes and medicines. The most common procedure is called fundoplication, where the top of the stomach is wrapped around the lower esophagus to strengthen the valve.

Living with this condition

Living with heartburn means being aware of what triggers your symptoms and making small adjustments. Keep a diary of foods and activities that bring on heartburn, and avoid them when possible. Have antacids on hand if you need quick relief.

Lifestyle tips

• Maintain a healthy weight.
• Avoid lying down after meals – try to stay upright for at least 2–3 hours.
• Elevate the head of your bed.
• Quit smoking and limit alcohol.
• Manage stress with relaxation techniques, as stress can worsen heartburn.

Diet and exercise

Eat smaller meals and chew food slowly. Avoid trigger foods. Include plenty of fruits, vegetables, whole grains, and lean proteins. Regular exercise can help with weight control, but avoid vigorous exercise right after eating. Walking after a meal is fine.

Mental health and emotional wellbeing

Chronic heartburn can be frustrating and may cause anxiety about eating or sleep. It is normal to feel worried. Talk to your doctor about how heartburn affects your quality of life. Stress management techniques like deep breathing, meditation, or talking with a counselor can help.

Prevention

You cannot always prevent heartburn, but you can lower your chances by maintaining a healthy weight, eating smaller meals, avoiding trigger foods, not lying down after eating, and not smoking.

Complications

If left untreated

• Esophagitis – inflammation of the esophagus that can cause pain and trouble swallowing.
• Strictures – narrowing of the esophagus from scar tissue.
• Barrett's esophagus – changes in the lining of the esophagus that can increase the risk of esophageal cancer (this is rare).
• Respiratory problems – stomach acid can be breathed into the lungs, causing cough, asthma, or pneumonia.

Long-term outlook

For most people, heartburn can be managed well with simple changes and medicines. Even if you have Barrett's esophagus, regular check-ups can catch any changes early. Although complications are possible, they are uncommon, and treatment is very effective. You can live a full, comfortable life with heartburn by working with your doctor.
