screening for acid reflux

Overview

Acid reflux happens when stomach acid flows back up into the esophagus — the tube that carries food from your mouth to your stomach. Screening for acid reflux means having a doctor check for signs of reflux and any damage to your esophagus, especially if you have symptoms or are at higher risk.

Yes. Acid reflux affects millions of people worldwide. Occasional heartburn is very common, but when it happens often, it may be a sign of something called gastroesophageal reflux disease (GERD).

Acid reflux can happen at any age. It is more common in adults, especially people who are overweight, pregnant, or who have a hiatal hernia. Older adults may have different symptoms, so it can be missed.

Symptoms

Common symptoms

• A burning feeling in your chest (heartburn), often after eating
• A sour or bitter taste in your mouth
• Regurgitation — food or liquid coming back up
• A feeling of a lump in your throat
• A hoarse voice or painful swallowing
• A chronic cough that is not related to a cold

Symptoms in children

• Spitting up or vomiting more than usual
• Coughing that does not go away
• A poor appetite or trouble gaining weight
• Irritability, especially after meals

Symptoms in older adults

• Chest pain that might feel like heartburn
• Trouble swallowing
• Unexplained weight loss
• Anemia — feeling tired and looking pale
• Ongoing vomiting

Causes

Main causes

• A weak muscle at the bottom of the esophagus that normally keeps stomach contents down
• A hiatal hernia — when part of the stomach pushes through the diaphragm
• Eating large meals or lying down right after eating
• Foods and drinks like fatty foods, caffeine, alcohol, and spicy foods
• Extra pressure on the abdomen from obesity or pregnancy

Risk factors

• Being overweight or obese
• Being pregnant
• Smoking or exposure to secondhand smoke
• Eating late at night
• Taking certain medicines (like some pain relievers) — talk to your doctor if you are concerned

When to see a doctor

See a doctor urgently if:

• You have chest pain together with sweating, nausea, or shortness of breath — call emergency services
• You vomit blood or have black, tarry stools
• You have severe abdominal pain or a feeling like food is stuck behind your breastbone

Book a routine appointment if:

• You have heartburn more than twice a week
• Your symptoms last for more than a few weeks despite simple changes
• You have trouble swallowing or a persistent hoarse voice
• You are losing weight without trying or have a poor appetite

Diagnosis

A doctor will ask about your symptoms, medicines, and medical history. They may do a physical exam and, if needed, run tests to look at your esophagus and measure how often acid flows back up.

Tests that may be done

• Endoscopy — a thin, flexible tube with a camera is used to look inside your esophagus and stomach. This is the most direct way to see damage.
• pH monitoring — a small device measures how much acid stays in your esophagus over 24 hours.
• Barium swallow — you drink a chalky liquid, and X-rays show its movement through your digestive tract.

What to expect at your appointment

For most tests, you may be asked to stop eating or drinking for several hours beforehand. You will likely receive a sedative to help you relax during an endoscopy, and the test usually takes about 15 minutes. You can usually go home the same day.

Treatment

Treatment for acid reflux starts with lifestyle changes. If that is not enough, doctors may recommend medicines to reduce stomach acid, and in severe cases, surgery can help strengthen the valve between the stomach and the esophagus.

Self-care at home

• Eat smaller meals and avoid large, heavy meals
• Avoid foods and drinks that trigger your symptoms, like spicy foods, alcohol, and caffeine
• Do not lie down for 2 to 3 hours after eating
• Raise the head of your bed about 15–20 cm (6–8 inches)
• Maintain a healthy weight
• Stop smoking or avoid tobacco

Medical treatments

There are several types of medicines that can help. Antacids work quickly to neutralize acid in the stomach. Other medicines lower the amount of acid your stomach makes, and some help the stomach empty faster. Your doctor or pharmacist can explain the options and which one might be right for you. Do not start or stop any medicine without talking to a healthcare provider.

When is surgery considered?

If lifestyle changes and medicines do not control your symptoms, or if you have severe damage to your esophagus, a doctor may recommend a procedure to tighten the valve where the stomach meets the esophagus.

Living with this condition

Living with acid reflux means paying attention to when and what you eat, keeping a comfortable position after meals, and taking any prescribed treatment as directed. Keep a symptom diary to help you and your doctor see what works.

Lifestyle tips

• Eat your largest meal at midday and keep evening meals light
• Wear loose-fitting clothes that do not put pressure on your belly
• Sleep with your head elevated
• Chew food slowly and thoroughly
• Manage stress with deep breathing, gentle movement, or talking with someone

Diet and exercise

A balanced diet is important. Healthy weight, regular physical activity, and avoiding trigger foods can all help. Light exercise like walking is fine, but avoid strenuous exercise right after a meal.

Mental health and emotional wellbeing

Dealing with pain and sleeping problems can be stressful. Anxiety and stress can also make reflux worse. It is okay to ask for help from a mental health professional if you feel overwhelmed.

Prevention

You cannot always prevent acid reflux, but you can lower your chances by staying at a healthy weight, eating mindfully, and avoiding known triggers. Early screening helps find changes in the esophagus before they become serious.

Screening programmes

Routine screening for acid reflux is not needed for everyone. However, if you have long-term, frequent reflux or other risk factors, your doctor may suggest an endoscopy to screen for damage like Barrett's esophagus. Talk to your provider about what is right for you.

Complications

If left untreated

• Inflammation and sores (esophagitis) in the esophagus
• Narrowing of the esophagus that makes swallowing hard (stricture)
• Barrett's esophagus — a change in the lining of the esophagus that can raise the risk of cancer
• Asthma-like breathing problems or repeated pneumonia from breathing in acid

Long-term outlook

Most people with acid reflux get better with lifestyle changes and proper treatment. When damage has started, there are effective ways to manage it and monitor it closely. With regular follow-up, you can protect your health and live well.
