What is heartburn?

Heartburn, also known as acid reflux or Gastroesophageal Reflux Disease (GORD), is a condition in which stomach acid is regurgitated and backs up in the oesophagus.

This can cause a burning feeling in the centre of your chest. An unpleasant sour taste or smell may linger in your mouth for some time after experiencing heartburn, and your voice may become hoarse and scratchy. You may develop a cough afterwards, though these symptoms usually pass briefly.

In some cases, heartburn can cause nausea and vomiting.

Where the oesophagus joins the stomach is a collection of muscles known as the lower oesophageal sphincter (LOS). This muscle acts like a gate. When we swallow food, the LOS opens so that the food can enter the stomach. The stomach releases acid, and the sphincter closes, preventing the acid from travelling up the oesophagus during digestion.

Damage to the LOS can cause it to function incorrectly, resulting in the LOS remaining open when digestion begins. In this scenario, stomach acid can escape the stomach through the oesophagus. Unlike the stomach, the oesophagus is not equipped with cells which can neutralise the strong stomach acid by secreting an alkali. As a result, the stomach acid burns the oesophagus and causes pain.

Chronic heartburn (GORD) can cause irreversible damage to the cells in the oesophagus and increases the risk of developing more serious conditions such as Barrett's oesophagus or oesophageal cancer.

For people with asthma, GORD can make symptoms worsen and may have an impact on the quality of their breathing. Speak to your doctor if your gastroesophageal reflux is affecting your asthma for further advice.

What causes heartburn?

It's not always clear why heartburn happens to some people. Though, diet and lifestyle factors can be the cause of the condition or exacerbate symptoms. A common cause of heartburn is indigestion (dyspepsia). When indigestion is the suspected cause of acid reflux, other symptoms such as nausea (feeling sick), burping and wind may also be present.

The following foods can cause acid reflux:

  • Acidic foods
  • Alcohol
  • Chocolate
  • Coffee
  • Fatty foods
  • Spicy food

Other factors which contribute to acid reflux and heartburn include:

  • Anxiety
  • Hiatus hernia
  • Medicines (such as NSAIDs like Ibuprofen)
  • Pregnancy
  • Smoking
  • Stress

You may find your symptoms are worse after eating. Lying down and bending over may also make you feel worse, increasing the chances of stomach acid travelling up your gullet.

How to treat heartburn?

There are multiple treatments for heartburn. Some treatments are available over the counter from pharmacies. Other treatments, such as pantoprazole, require a prescription.

If you experience heartburn regularly, you should speak to your doctor. They will be able to determine the cause of your heartburn and determine the most suitable heartburn treatment for you.

Proton pump inhibitors (PPIs) are often prescribed for chronic GORD and heartburn. This group of medicines prevents the stomach from making excessive acid during the digestion process.

Other antacids, such as Rennie and Gaviscon, neutralise the excess acid in the stomach.

You can buy heartburn treatments online from Prescription Doctor. To begin your order, complete our online medical form for one of our doctors to review. If your order is approved before 3 pm on a weekday, our UK-based pharmacy can dispense and dispatch heartburn medicine straight to your door.

How can I prevent heartburn?

In many cases, heartburn can be prevented by changing your lifestyle, such as adjusting your diet or quitting smoking. If your symptoms are particularly disruptive to your lifestyle, speak to your doctor about available treatments.

It may be a good idea to record your bouts of heartburn in a diary. Keeping a record of your symptoms can be valuable to both yourself and your doctor in determining possible acid reflux triggers. You should include the following:

  • The date and time your symptoms occur
  • How long have your symptoms lasted
  • How painful the symptoms were on a scale from 1 to 10
  • Whether you experienced coughing, burping or difficulty breathing or swallowing
  • The food you ate before the symptoms developed
  • The activities you did before experiencing your symptoms

Adjusting your eating habits may help to mitigate your symptoms. Eating habits go beyond what you eat and encapsulate how you eat. Aim to eat at regular intervals during the day and balance your portions accordingly. If you have a later lunch, consider eating a breakfast which consists of slow releasing energy such as whole grain cereal or oats. Avoid fizzy drinks and foods which contain a high amount of refined sugars, such as sickly sweet desserts, as they can contribute to your symptoms. Each meal should provide enough energy until your next meal. When eating a meal, sit down and slow down; chew your food properly before swallowing and sit down while eating to aid digestion. Take into account your post-eating habits - what do you do after eating? You should wait at least an hour after eating a meal before exercising. If you take a nap after eating dinner, you may need to make adjustments to your resting position to prevent acid reflux.

The NHS recommends adjusting your bed so your head is higher than your waist. One way of achieving this is to prop your head and shoulders up on some pillows. This will reduce the chance of stomach acid entering your oesophagus while resting.

Numerous studies have indicated that sleeping on your right-hand side can aggravate heartburn symptoms. It is believed that sleeping on your right relaxes the lower oesophageal sphincter, allowing acid to enter the oesophagus during sleep. Sleeping on your left-hand side, however, may ease your heartburn symptoms.

Other tips for preventing acid reflux include:

  • Avoiding or limiting alcohol consumption
  • Losing weight if you are overweight
  • Avoiding tight clothing around your waist

If you suspect your acid reflux is a side effect of your medication, speak to your doctor or a pharmacist for advice. Always speak to your doctor or pharmacist about any side effects you experience. You should never stop taking a medicine unless your doctor has instructed you.
