acid reflux that comes and goes

Overview

Acid reflux is when stomach acid flows back up into the tube that connects your mouth to your stomach, called the esophagus. It can cause a burning feeling in your chest or throat. When it happens now and then (not all the time), we call it 'occasional' or 'intermittent' acid reflux.

Yes, occasional acid reflux is very common. Nearly everyone has heartburn at some point. It becomes a problem when it happens frequently.

Acid reflux can affect anyone, but it is more common in adults, especially those who are overweight, pregnant, or smoke. Certain medical conditions can also increase the risk.

Symptoms

Common symptoms

• Heartburn – a burning pain or discomfort in the middle of your chest, often after eating or when lying down.
• Regurgitation – a sour or bitter taste in your mouth, or feeling like food or liquid is coming back up.
• Burping or bloating.
• Nausea or feeling sick after meals.

Symptoms in children

• Spitting up or vomiting more than usual.
• Fussiness or crying during or after feeding.
• Poor appetite or trouble gaining weight.
• Frequent coughing or wheezing.

Symptoms in older adults

• Less obvious heartburn; instead they may have chest discomfort, difficulty swallowing, or a feeling of a lump in the throat.
• Hoarseness or a chronic cough.
• Asthma-like symptoms or repeated lung infections from breathing in small amounts of acid.

Causes

Main causes

• A weak or relaxed valve (the lower esophageal sphincter) that normally keeps stomach acid from flowing back up.
• A hiatal hernia – when part of the stomach pushes up through the diaphragm into the chest.
• Increased pressure on the stomach from obesity, pregnancy, or heavy lifting.

Risk factors

• Eating large meals or lying down right after eating.
• Being overweight or obese.
• Smoking or using tobacco.
• Drinking alcohol, caffeine, or carbonated drinks.
• Eating trigger foods like spicy, fatty, or acidic foods (e.g., tomatoes, citrus, chocolate).
• Taking certain medications (like some pain relievers or blood pressure drugs).

When to see a doctor

See a doctor urgently if:

• Chest pain that feels like a heart attack (see emergency symptoms).
• Vomiting blood or passing black stools.
• Severe trouble swallowing.

Book a routine appointment if:

• Heartburn that happens two or more times a week.
• Symptoms that do not improve with lifestyle changes or over-the-counter antacids.
• Difficulty swallowing or feeling like food gets stuck.
• Chronic cough, hoarseness, or asthma that might be related to reflux.

Diagnosis

Doctors usually diagnose acid reflux based on your symptoms and medical history. If symptoms are frequent or severe, they may recommend tests to check for damage or other causes.

Tests that may be done

• Upper endoscopy – a thin, flexible tube with a camera is passed down your throat to look at your esophagus and stomach.
• pH monitoring – a small device is placed in your esophagus to measure how much acid backs up over 24 hours.
• Barium swallow – you drink a chalky liquid that shows up on X-rays, helping the doctor see any blockages or hernias.

What to expect at your appointment

Your doctor will ask about your symptoms, diet, and lifestyle. They may suggest trying lifestyle changes and antacids first. If needed, they will explain any tests in detail. Most tests are quick and not painful.

Treatment

Treatment for occasional acid reflux usually starts with simple self-care and over-the-counter remedies. If symptoms persist, doctors may recommend stronger medications or, in rare cases, surgery.

Self-care at home

• Eat smaller, more frequent meals.
• Avoid foods and drinks that trigger your symptoms (spicy, fatty, acidic, caffeine, alcohol).
• Do not lie down for at least 2–3 hours after eating.
• Elevate the head of your bed by 6–8 inches (using blocks or a wedge pillow).
• Lose weight if you are overweight.
• Stop smoking.

Medical treatments

If self-care is not enough, doctors may recommend medications that reduce stomach acid. These include antacids (which neutralize acid) and medications that block acid production (called H2 blockers or proton pump inhibitors). Some are available over the counter, others by prescription. Always follow your doctor's advice on how to take them.

When is surgery considered?

Surgery is rarely needed. It may be considered if medications do not work, or if you have a hiatal hernia causing severe symptoms. 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

Living with intermittent acid reflux often means being mindful of your habits. Keep antacids handy for flare-ups, and pay attention to what triggers your symptoms. With small adjustments, most people can keep reflux under control.

Lifestyle tips

• Maintain a healthy weight.
• Avoid tight clothing around your waist.
• Eat slowly and chew food well.
• Stay upright after meals.
• Manage stress – it can make symptoms worse.

Diet and exercise

A balanced diet with plenty of vegetables, lean proteins, and whole grains can help. Avoid your personal trigger foods. Gentle exercise like walking after meals can aid digestion, but vigorous exercise right after eating may worsen reflux.

Mental health and emotional wellbeing

Frequent heartburn can be uncomfortable and disrupt sleep, which may cause stress or anxiety. If you feel worried, talk to your doctor. They can help you manage both the physical and emotional aspects.

Prevention

In many cases, yes. By avoiding triggers, eating smaller meals, not lying down after eating, and keeping a healthy weight, you can reduce how often acid reflux happens.

Complications

If left untreated

• Esophagitis – inflammation of the esophagus that can cause pain and bleeding.
• Barrett's esophagus – changes in the lining of the esophagus that can increase the risk of esophageal cancer.
• Strictures – narrowing of the esophagus from scarring, making swallowing difficult.
• Respiratory problems – like asthma, chronic cough, or pneumonia from acid entering the lungs.

Long-term outlook

For most people, occasional acid reflux is manageable and does not lead to serious problems. With proper self-care and medical guidance when needed, you can keep symptoms under control and protect your health. Regular check-ups with your doctor help catch any changes early.
