acid reflux self care basics

Overview

Acid reflux happens when stomach acid flows backward into the tube that connects your mouth to your stomach (your food pipe, also called the oesophagus). This can cause a burning feeling in your chest, known as heartburn, and a sour taste in your mouth.

Yes. Many people experience acid reflux from time to time. It is one of the most common digestive problems, and about one in five people may have symptoms regularly.

Acid reflux can affect people of all ages, including children and older adults. It is more likely if you are overweight, pregnant, or taking certain medicines. Older adults may have different symptoms and should check with their doctor.

Symptoms

Common symptoms

• A burning feeling in your chest (heartburn), often after eating or at night
• A sour or bitter taste in your mouth
• Regurgitation – food or sour liquid coming back up into your mouth
• A feeling of a lump in your throat
• A dry cough, sore throat, or hoarse voice
• Difficulty sleeping due to discomfort
• Nausea or bloating

Symptoms in children

• Spitting up or vomiting more than usual
• Irritability, especially after feeding
• Poor feeding or refusing food
• Frequent coughing or wheezing
• A hoarse voice or sore throat

Symptoms in older adults

• Less typical heartburn and more hoarseness or throat clearing
• Wheezing or a feeling that food sticks
• Difficulty swallowing or pain with swallowing
• Unexplained chest pain, which should always be checked with a doctor

Causes

Main causes

• The muscle at the bottom of the food pipe (lower oesophageal sphincter) does not tighten properly, so stomach acid can wash back up.
• Certain foods and drinks relax this muscle or irritate the stomach, such as fatty foods, spicy foods, chocolate, mint, caffeine, and alcohol.
• Eating large meals or lying down soon after eating can push acid upward.
• Increased pressure on the stomach, like from pregnancy, overweight, or straining, can make reflux more likely.

Risk factors

• Being overweight or obese
• Pregnancy
• Smoking or regular exposure to secondhand smoke
• Having a hiatal hernia (when the top of the stomach pushes up through the diaphragm)
• Taking certain medicines, such as anti-inflammatory painkillers or some asthma medicines
• Eating late at night or very large meals
• Stress and anxiety, which can make symptoms worse

When to see a doctor

See a doctor urgently if:

• If you have difficulty swallowing or pain when swallowing
• If you are vomiting blood or have black, tarry stools
• If you have severe or persistent chest pain – call your local emergency number if it feels serious
• If you are losing weight without trying
• If you have symptoms that wake you from sleep often

Book a routine appointment if:

• If you get acid reflux more than twice a week
• If your symptoms do not improve with self-care after a few weeks
• If heartburn is getting more frequent or more painful
• If you need to take over-the-counter antacids or acid reducers almost every day
• If you have a persistent cough or hoarse voice with no clear cause

Diagnosis

A doctor can often diagnose acid reflux by listening to your symptoms and asking about your health and lifestyle. They may also suggest trying a few weeks of self-care or a medical treatment to see if you improve. In some cases, tests are needed if symptoms are severe, unusual, or not getting better.

Tests that may be done

• Endoscopy (a thin, flexible tube with a camera is passed into your food pipe and stomach to look for damage)
• Acid monitoring (a small device measures how much acid in your food pipe during a day)
• A barium swallow X-ray (you drink a special liquid that coats your digestive tract so it shows up clearly on X-ray)

What to expect at your appointment

Your doctor may start with lifestyle changes and a medicine trial before doing tests. If they recommend a test, it is usually quick, and you will be given clear instructions beforehand. After the test, the doctor will explain the results and suggest the next steps.

Treatment

Treatment for acid reflux usually begins with self-care and lifestyle changes. If these are not enough, a healthcare provider may recommend medicines that reduce acid production, neutralise acid, or help your stomach empty faster. More serious cases may need specialised care or, rarely, surgery.

Self-care at home

• Eat smaller, more frequent meals instead of large ones.
• Avoid trigger foods and drinks, such as spicy foods, fatty foods, chocolate, mint, coffee, and alcohol.
• Do not lie down for at least 2–3 hours after eating.
• Elevate the head of your bed about 15–20 cm (6–8 inches) by putting blocks under the headposts.
• Stay at a healthy weight or lose weight if you are overweight.
• Quit smoking – it weakens the muscle that stops acid from coming up.
• Wear loose clothing around your waist, and avoid bending forward after meals.
• Chew food slowly and give yourself time to digest.

Medical treatments

Several types of medicine can help control acid reflux. Antacids neutralise stomach acid quickly for fast relief. Other medicines called acid reducers (H2 blockers) lower how much acid your stomach makes. A stronger group called proton pump inhibitors block acid production and help heal damage to the food pipe. Some medicines are available without a prescription, but stronger ones require a doctor's prescription. Always ask your healthcare provider or pharmacist what is appropriate for you.

When is surgery considered?

Surgery is only considered when medicines do not work well, you cannot take medicines, or there is severe damage to the food pipe. A common procedure tightens the valve at the bottom of the food pipe to make it harder for acid to come back up. Your doctor will explain all the risks and benefits if surgery is ever suggested.

Living with this condition

Living with acid reflux often means building simple habits into your daily routine. Keep a diary of what you eat and how you feel – this can help you spot your own triggers. Plan meals so you are not eating too late, and give yourself time to sit upright after eating. Carry allowed heartburn relief with you if recommended by your doctor or pharmacist.

Lifestyle tips

• Maintain a healthy weight to reduce pressure on your stomach.
• Sleep with your head elevated using extra pillows or a wedge.
• Manage stress with breathing exercises, gentle walks, or hobbies you enjoy.
• Wear comfortable clothes and avoid tight belts or waistbands.
• Stop smoking and limit alcohol, as both can make reflux worse.

Diet and exercise

A balanced diet with mostly vegetables, fruits, whole grains, and lean proteins is good for your digestive system. Try to avoid foods that trigger your symptoms, but do not cut out whole food groups without medical advice. Regular exercise like walking, swimming, or cycling can help you manage your weight and reduce reflux – but wait at least an hour after eating before vigorous activity.

Mental health and emotional wellbeing

Dealing with constant heartburn can be tiring and stressful. It may affect your sleep, your appetite, and your mood. It is normal to feel anxious about symptoms. If you notice signs of low mood or worry, talk to your healthcare provider – they can offer support and effective ways to cope.

Prevention

Not always, but many cases of acid reflux can be prevented or made less frequent by the same lifestyle habits used to treat it. Eating reasonable portions, choosing trigger-free foods, staying at a healthy weight, and not lying down right after meals all help.

Complications

If left untreated

• Inflammation of the food pipe (oesophagitis), which can cause pain and bleeding
• The formation of a stricture, which is a narrowing of the food pipe that makes swallowing difficult
• A condition called Barrett's oesophagus, where the lining of the food pipe changes
• An increased risk of oesophageal cancer, which is very rare but more likely after years of severe reflux

Long-term outlook

The outlook for most people with acid reflux is good. With simple self-care and, if needed, medical treatment, the vast majority feel much better and can prevent damage to their food pipe. Even people with more persistent reflux usually manage it successfully with long-term care. There is every reason to be hopeful – you can take control and feel comfortable.
