acid reflux X ray explained

Overview

An acid reflux X-ray is a test that uses a special dye and X-rays to look at your esophagus, stomach, and the upper part of your small intestine. It helps doctors see if stomach acid is flowing back into your esophagus (acid reflux) and check for any damage or other problems.

Yes, acid reflux is very common, and X-rays are one way doctors may check for it if symptoms are persistent or concerning.

Acid reflux can affect people of all ages, but it is more common in adults, especially those who are overweight, pregnant, or have a hiatal hernia.

Symptoms

Common symptoms

• Heartburn (a burning feeling in the chest)
• Regurgitation (sour or bitter-tasting fluid coming up into the throat or mouth)
• Difficulty swallowing or a feeling of a lump in the throat
• Chest pain that is not related to heart problems
• Chronic cough, hoarseness, or sore throat

Symptoms in children

• Spitting up frequently
• Irritability during or after feeding
• Poor weight gain
• Recurrent vomiting
• Wheezing or pneumonia

Symptoms in older adults

• Heartburn that may be less intense but more persistent
• Difficulty swallowing
• Weight loss without trying
• Anemia (low red blood cells)

Causes

Main causes

• When the lower esophageal sphincter (a ring of muscle at the bottom of the esophagus) relaxes too often or doesn't close properly, allowing stomach acid to flow back up.
• Hiatal hernia (when part of the stomach pushes up through the diaphragm into the chest)

Risk factors

• Being overweight or obese
• Pregnancy
• Smoking
• Eating large meals or lying down after eating
• Certain foods (fatty, spicy, acidic)
• Certain medications (like some pain relievers or blood pressure drugs)
• Stress

When to see a doctor

See a doctor urgently if:

• You have difficulty swallowing that is getting worse.
• You have signs of bleeding (vomiting blood or black stools).
• You have unintentional weight loss.

Book a routine appointment if:

• Heartburn occurring more than twice a week.
• Symptoms that interfere with daily life or sleep.
• Over-the-counter medications not helping.
• Having symptoms for several weeks.

Diagnosis

Your doctor will first ask about your symptoms and medical history. They may recommend an X-ray with barium (upper GI series) to look for signs of acid reflux, hiatal hernia, or other problems. This test shows the shape and movement of your esophagus, stomach, and duodenum.

Tests that may be done

• Upper GI series (barium swallow) - you drink barium liquid and X-rays are taken as the liquid moves through your digestive tract.
• Endoscopy - a thin, flexible tube with a camera is passed through your mouth to look at the inside of your esophagus and stomach. This is often done if the X-ray is inconclusive or symptoms are severe.
• pH monitoring - a test that measures acid levels in the esophagus over 24 hours.

What to expect at your appointment

For the X-ray, you will be asked to drink a white, chalky liquid (barium). You may be asked to change positions during the X-ray. The test is painless, though some people feel bloated or nauseous from the barium. After the test, you can eat and drink normally unless told otherwise. The barium may make your stools white for a day or two.

Treatment

Treatment for acid reflux aims to reduce symptoms, heal damage to the esophagus, and prevent complications. It usually starts with lifestyle changes and over-the-counter remedies, then progresses to prescription treatments if needed.

Self-care at home

• Eat smaller, more frequent meals instead of large meals.
• Avoid lying down for at least 2-3 hours after eating.
• Raise the head of your bed by 6-8 inches to prevent nighttime reflux.
• Avoid foods and drinks that trigger your symptoms, such as fatty foods, spicy foods, citrus, chocolate, caffeine, and alcohol.
• Maintain a healthy weight.
• Quit smoking if you smoke.

Medical treatments

Doctors may recommend medications that reduce stomach acid or help the esophagus heal. These include acid reducers (H2 blockers) and proton pump inhibitors (PPIs). Always take medications as directed by your healthcare provider. Do not stop or change doses without consulting your doctor.

When is surgery considered?

Surgery, such as fundoplication (wrapping the top of the stomach around the lower esophagus), may be an option if medications do not work or if you have severe complications. Discuss the risks and benefits with your surgeon.

Living with this condition

Living with acid reflux often involves making adjustments to your daily habits. By following your treatment plan and avoiding triggers, most people can control their symptoms well.

Lifestyle tips

• Eat smaller meals and avoid trigger foods.
• Elevate the head of your bed.
• Wear loose-fitting clothes around your waist.
• Manage stress through relaxation techniques.
• Avoid eating late at night.

Diet and exercise

A balanced diet low in fatty and spicy foods can help. Some people find relief with a Mediterranean-style diet rich in fruits, vegetables, and whole grains. Gentle exercise, like walking after meals, may aid digestion, but avoid vigorous activity right after eating.

Mental health and emotional wellbeing

Chronic acid reflux can be stressful and affect your quality of life. It may cause anxiety about eating or sleeping. Talk to your doctor if you feel overwhelmed.

Prevention

You can reduce your risk of developing frequent acid reflux by maintaining a healthy weight, eating smaller meals, avoiding trigger foods, and not lying down after eating. However, some causes like hiatal hernia or pregnancy may not be preventable.

Complications

If left untreated

• Esophagitis (inflammation of the esophagus that can cause pain and difficulty swallowing)
• Esophageal stricture (narrowing of the esophagus due to scar tissue)
• Barrett's esophagus (changes in the lining of the esophagus that increase the risk of cancer)
• Chronic cough or asthma
• Dental erosion (from stomach acid in the mouth)

Long-term outlook

With proper treatment, most people with acid reflux can manage their symptoms effectively and prevent serious complications. It is important to follow your doctor's advice and have regular check-ups.
