In fact, did you know that indigestion is said to affect approximately 40% of people in the UK every year?

To learn more about indigestion, including what it’s caused by and what you can do to find targeted relief, we’ve got you covered. 

WHAT DOES INDIGESTION FEEL LIKE?

Indigestion, also known as dyspepsia, refers to a group of gastrointestinal symptoms that can be experienced in different ways.

For example, indigestion may be felt as a pain or discomfort in the upper abdomen (known as dyspepsia), a burning pain behind the breast bone (known as heartburn), or both at the same time. It can also often be accompanied by symptoms like bloating, flatulence, burping and a variety of others (but more on those later!).

Indigestion may also be described as occasional (happens once in a while), chronic (happens regularly for a few weeks or months) or functional (accompanied by long-term symptoms with no specific cause).

WHAT ARE THE MAIN SYMPTOMS OF INDIGESTION?

While indigestion is often associated with eating and drinking, it can also be triggered by other factors, including stress, medication or an underlying health condition.

When this happens, you may experience symptoms like:

  • Heartburn
  • Pain, a burning feeling or discomfort in your upper abdomen
  • Feeling uncomfortably full after eating
  • Feeling full too soon while eating a meal
  • Feeling bloated
  • Feeling sick (nausea)
  • Excessive burping or flatulence
  • Bringing up food or bitter-tasting fluids in your mouth (known as acid reflux)
  • Loud growling or gurgling in your stomach

While these symptoms might sound alarming, it’s important to remember that indigestion is a common problem that – in most cases – will only cause mild, occasional symptoms that won’t require medical advice.

That said, you should speak to your doctor if your symptoms become severe or you experience symptoms like blood in your vomit, constant pain in your abdomen, shortness of breath or black, tar-like stools, as these could all be signs of a more serious condition.  

WHAT CAUSES INDIGESTION?

Indigestion is thought to be caused by the acid inside our stomachs coming into contact with the sensitive lining of our digestive system. When this happens, the stomach acid breaks down the lining, causing it to become irritated and inflamed.

However, this inflammation isn’t what leads to the various symptoms of indigestion. Instead, indigestion is believed to be caused by the stomach lining becoming sensitive to contact with stomach acid or stretching (often after eating).

For this reason, indigestion is often associated with eating or drinking too much or too quickly. However, it may also be caused by a variety of other factors, such as:

  • Dietary triggers: certain foods and drinks can irritate the stomach and cause indigestion. These include fatty, greasy or spicy foods, citrus fruits, chocolate, caffeine and alcoholic beverages.
  • Eating habits: consuming large meals or eating too quickly may contribute to indigestion by putting pressure on the stomach and disrupting the normal digestion process.
  • Lifestyle factors: smoking, stress and anxiety may all increase your likelihood of experiencing symptoms associated with indigestion, such as feeling bloated.
  • Medications: some medications, like aspirin, ibuprofen, antibiotics and certain heart medicines, may irritate the stomach lining and lead to indigestion as a side effect.
  • Medical conditions: underlying health issues like gastro-oesophageal reflux disease (GERD/GORD), stomach ulcers, acid reflux, gastritis, hiatus hernia or, in rare cases, stomach cancer, can all cause symptoms of indigestion.
  • Infections: being infected by a bacteria called Helicobacter pylori is a common cause of indigestion and, in most cases, won’t cause any symptoms at all
  • Obesity: being overweight or obese can increase your risk of indigestion by putting extra pressure on the stomach and causing potential acid reflux.

INDIGESTION AND PREGNANCY

Being pregnant may increase your likelihood of getting indigestion because of two key contributing factors: firstly, the hormonal changes associated with pregnancy and, secondly, having a growing baby pressing against your stomach.

Indigestion is particularly common after you reach the 27-week mark of pregnancy, but you can also get other symptoms, like heartburn, at any point throughout. In fact, up to 25% of women are said to experience heartburn during pregnancy!

However, by making certain adjustments to your diet and lifestyle, this may help to ease your symptoms. Your pharmacist can offer advice on how to deal with any uncomfortable feelings or pain you experience as well, and recommend the most suitable medicines for you to use while you’re pregnant*. 
 

HOW TO MANAGE INDIGESTION: TREATMENT AND RELIEF

Living with the symptoms of indigestion can be uncomfortable, reduce your quality of life and even impact your productivity at work. So, what can you do to help prevent them?

Fortunately, there are several ways to do just that. But, knowing which type of treatment is right for you will depend on what’s causing your indigestion and how severe your symptoms are.

If your indigestion is caused by an underlying health condition, or you’re ever unsure about your symptoms, speak to your doctor for their advice.

For mild cases of indigestion, however, the advice listed below may be enough to help ease your symptoms. 

WATCH WHAT YOU EAT AND DRINK

Since indigestion is often associated with your diet, thinking about what you eat and drink may help to manage your symptoms.

For example, why not make a note of any particular foods or drinks that seem to make your indigestion worse? That way, you’ll know exactly what to avoid in the future!

Some of the main culprits for causing indigestion include rich, spicy and fatty foods, citrus fruits and drinks that contain caffeine (such as tea, coffee or fizzy drinks) or alcohol. Cutting down on these may help to reduce your symptoms and help prevent them from getting any worse.

Instead, try to eat a healthy, well-balanced diet, prioritising foods like non-citrus fruits, vegetables, beans, nuts, pulses, fish, eggs, meat and high-fibre starchy products. And when it comes to cooking, try to make any spicy meals you would normally have (like curries) milder by using herbs as an alternative and, where possible, grill your food instead of frying it.

REDUCE YOUR MEAL SIZE

Eating large meals in one go can stretch and irritate your stomach lining which can trigger indigestion.

As such, eating little and often throughout the day, taking the time to eat slowly and chew each mouthful, and avoiding late-night snacking could help prevent symptoms like acid reflux and heartburn.

Eating meals in this way may also make it easier for you to try and maintain a healthy weight, helping to reduce the pressure on your stomach and limiting your likelihood of acid reflux. 

STOP SMOKING

If you smoke cigarettes, the chemicals you inhale may contribute towards indigestion.

This is because of the effects that smoking can have on what’s known as the lower oesophageal sphincter (a large muscular ring located at the entrance of your stomach), which separates your oesophagus from your stomach.

When working as it should, this ring of muscle is supposed to open when you’re eating, allow food to pass through and close shortly afterwards. However, smoking can cause it to relax, allowing the acid contained within your stomach to escape upwards into your oesophagus, resulting in symptoms like acid reflux.

Quitting smoking may help to prevent this from happening and reduce any acid reflux-related symptoms you’re experiencing.

KEEP YOUR STRESS LEVELS DOWN

Stress, anxiety and depression may all contribute to or worsen symptoms of indigestion. So prioritising techniques that lower your stress or anxiety levels could help reduce your indigestion symptoms.

For example, why not try:

  • Using calming breathing exercises or meditation
  • Talking therapy (like cognitive behavioural therapy) or counselling
  • Performing gentle exercises (such as yoga)
  • Getting a good night’s sleep (raising your head and shoulders when in bed may help to reduce symptoms like acid reflux)
  • Avoid gambling (as this can increase your stress level)
  • Avoid using alcohol, cigarettes or drugs
  • Using time-management techniques and plan ahead
  • Talking about your feelings to a friend, family member, health professional or counsellor

USE OVER-THE-COUNTER MEDICINES

Lifestyle changes can be useful for preventing indigestion in the future but, if you’re looking for fast relief from your symptoms, over-the-counter medications may help.

Available from your local pharmacist, these medications typically include antacids and alginates and are designed to help ease the burning sensation or pain often associated with indigestion.

Rennie® Peppermint, for example, is an antacid that provides fast-acting, effective relief from indigestion.

It does this through its calcium carbonate and magnesium carbonate formula, which works quickly to neutralise excess stomach acid by converting it into water and soluble mineral salts.

However, the effects of antacids only last for a few hours at a time. So, to get the most out of them, it’s best to take them as soon as your symptoms start to occur. 

SEEK PROFESSIONAL ADVICE

If you find that lifestyle changes and over-the-counter medicines aren’t reducing your symptoms of indigestion, or that you’re in severe pain, keep getting indigestion or keep being sick, it’s important to speak to your doctor.

They’ll be able to discuss the symptoms you’ve been experiencing, review any existing medication you may be taking to determine what’s causing your indigestion and provide you with personalised advice and alternative treatments to combat your specific symptoms.
