acid reflux risk reduction

Overview

Acid reflux is a common condition where stomach acid flows backwards into the tube that connects your mouth and stomach. This tube is called your food pipe, or oesophagus. The acid can irritate the food pipe, causing symptoms like heartburn. You can reduce your risk of acid reflux by making everyday changes to your eating and lifestyle habits.

Yes. Acid reflux is very common. In the UK, around 1 in 10 to 1 in 5 adults experience reflux symptoms regularly. Many more have occasional reflux.

It can affect anyone, including children and older adults. You are more likely to get it if you are overweight, pregnant, over 40, or a smoker.

Symptoms

Common symptoms

• heartburn (a burning feeling in the chest or throat)
• regurgitation (acid or food coming back into the mouth)
• sour or bitter taste in the mouth
• difficulty swallowing
• a feeling of a lump in the throat
• persistent cough or hoarseness

Symptoms in children

• vomiting or spitting up frequently
• coughing, especially at night
• poor appetite and slow weight gain
• stomach ache or irritability after eating

Symptoms in older adults

• chest pain (not always heartburn)
• trouble swallowing
• hoarseness or voice changes
• repeated pneumonia or bronchitis
• anaemia due to slow blood loss

Causes

Main causes

• a weak valve between the stomach and food pipe
• a hiatus hernia (when part of the stomach moves into the chest)
• extra pressure on the stomach from being overweight or pregnant

Risk factors

• eating large meals or lying down right after eating
• being overweight (especially around the middle)
• eating foods that relax the valve, such as fatty foods, chocolate, caffeine, alcohol, or spicy food
• smoking
• pregnancy
• stress and anxiety

When to see a doctor

See a doctor urgently if:

• You have symptoms that are getting worse or not improving with self-care
• You have trouble swallowing or pain with swallowing
• You have weight loss without trying, or vomiting
• You have chest pain that is hard to tell from a heart problem

Book a routine appointment if:

• You get heartburn more than twice a week
• You often need to take over-the-counter acid reflux medicine
• Your symptoms wake you at night
• You have had heartburn for several weeks or more

Diagnosis

A doctor will usually diagnose acid reflux based on your symptoms and health history. They may ask about your eating habits and any medicines you take. If symptoms continue or are severe, the doctor may refer you for tests.

Tests that may be done

• endoscopy (a thin tube with a camera is passed into your food pipe)
• pH monitoring (a small tube measures acid in your food pipe over 24 hours)
• barium swallow (a drink shows your food pipe and stomach on X-rays)
• oesophageal manometry (a test to check how well your food pipe squeezes)

What to expect at your appointment

Your doctor will talk with you about your symptoms and may examine your chest and abdomen. They may suggest trying lifestyle changes first, and only order tests if your symptoms are unusual, severe, or do not improve.

Treatment

Treatment for acid reflux focuses on reducing acid, protecting your food pipe, and preventing symptoms. Most people start with lifestyle changes. If these are not enough, there are several types of medicine and, rarely, surgery.

Self-care at home

• Eat smaller meals, four to five times a day instead of two large meals
• Avoid eating within 3 hours of going to bed
• Raise the head of your bed by 10–20 cm (using blocks under the bed legs, not extra pillows)
• Avoid tight belts, waistbands, or bending over after meals
• Lose weight if you are overweight
• Stop smoking and limit alcohol

Medical treatments

Your doctor or pharmacist can advise on a suitable treatment. Options include antacids to neutralise acid, alginates that form a barrier on top of the stomach, and medicines called H2 blockers or proton pump inhibitors that reduce the amount of acid your stomach makes. Always take these under the guidance of a healthcare professional.

When is surgery considered?

If symptoms are severe or medicines do not control the reflux, a specialist may suggest a surgical procedure to tighten the valve between the stomach and the food pipe. This is usually considered only when other treatments have not worked.

Living with this condition

Day-to-day, you can live well with acid reflux by keeping it under control. Stick to a routine, keep a simple diary of foods and drinks that trigger your symptoms, and always carry a bottle of water. If you take medicine for reflux, take it as directed by your doctor.

Lifestyle tips

• Maintain a healthy weight
• Eat slowly and chew thoroughly
• Stay upright after eating
• Avoid high-fat, spicy, or highly acidic foods if they bother you
• Manage stress with relaxation techniques like deep breathing or walking
• Sleep with the head of your bed elevated

Diet and exercise

A balanced diet rich in vegetables, lean protein, and whole grains is best for everyone. It is also a good idea to exercise regularly, as staying active helps you manage your weight and reduces pressure on your stomach. Wait at least two hours after a meal before doing strenuous exercise.

Mental health and emotional wellbeing

Living with frequent reflux can be stressful and may affect your sleep and mood. Stress does not directly cause reflux, but it can make symptoms feel worse. If you feel anxious or low because of your symptoms, talk to your doctor. You can also reach out to a counsellor or support service for help.

Prevention

You cannot always prevent acid reflux, but many cases can be avoided or improved by keeping a healthy weight, not smoking, limiting alcohol, and practicing good eating habits. These same steps reduce the risk of reflux and its complications.

Screening programmes

There is no routine screening test for acid reflux. If you have long-lasting or frequent heartburn, your doctor may suggest an internal examination of your food pipe to check for damage, even if your symptoms have improved.

Complications

If left untreated

• inflamed food pipe (oesophagitis)
• narrowing of the food pipe (stricture)
• Barrett's oesophagus (changes in the lining of the food pipe that can raise cancer risk)
• repeated lung infections from breathing acid into the airways

Long-term outlook

For most people, acid reflux can be well controlled with lifestyle changes and simple treatments. With the right care, symptoms usually improve quickly and the food pipe can heal. See a doctor for regular review if you have long-term symptoms, but remember that most people do very well.
