Heart burn - when to see a doctor

Almost everyone experiences heartburn from time to time. It might appear after a spicy meal, a takeaway, or a few drinks with friends. Usually, the discomfort passes quickly and is forgotten about.

However, if you're asking yourself, "Why do I get heartburn so often?", you're certainly not alone.

Persistent heartburn affects thousands of people across the UK and can have a significant impact on daily life. Whether it's disrupting your sleep, affecting your enjoyment of food, or leaving you constantly reaching for antacids, recurring symptoms shouldn't simply be accepted as normal.

While occasional heartburn is common, frequent symptoms may indicate an underlying digestive issue that deserves further attention.

What Is Heartburn?

Heartburn is a burning sensation that develops in the chest, usually behind the breastbone. Despite the name, it has nothing to do with your heart.

The sensation occurs when stomach acid travels back up into the oesophagus, the tube that carries food from your mouth to your stomach. This is known as acid reflux.

Common symptoms include:

  • A burning feeling in the chest after eating
  • A sour or acidic taste in the mouth
  • Food or liquid coming back up into the throat
  • A chronic cough
  • Hoarseness or a sore throat
  • Symptoms that worsen when lying down

Some people experience symptoms only occasionally, while others deal with heartburn several times a week.

Why Do I Get Heartburn So Often?

There isn't always a single cause. In many cases, a combination of lifestyle factors, dietary habits, and underlying digestive conditions can contribute to recurring symptoms.

Gastro-Oesophageal Reflux Disease (GORD)

One of the most common causes of frequent heartburn is Gastro-Oesophageal Reflux Disease, often shortened to GORD.

Normally, a ring of muscle at the bottom of the oesophagus prevents stomach acid from moving upwards. When this muscle weakens or relaxes too often, acid can repeatedly escape into the oesophagus.

People with GORD often experience:

  • Regular heartburn
  • Acid reflux
  • Symptoms after meals
  • Night-time discomfort
  • Persistent throat irritation

Without treatment, long-term reflux can irritate the lining of the oesophagus, which is why persistent symptoms should not be ignored.

Certain Foods and Drinks

Many people find that specific foods trigger their heartburn.

Common culprits include:

  • Spicy foods
  • Fatty meals
  • Chocolate
  • Citrus fruits
  • Tomatoes
  • Coffee
  • Fizzy drinks
  • Alcohol

However, triggers vary from person to person. What causes symptoms for one individual may have little effect on someone else.

Keeping a simple food diary can help identify patterns and highlight potential triggers.

Eating Large Meals

Heartburn after eating is particularly common following large meals.

When the stomach becomes overly full, pressure increases, making it easier for stomach acid to move upwards into the oesophagus.

This is why many people notice symptoms after:

  • Restaurant meals
  • Sunday lunches
  • Holiday celebrations
  • Late-night eating

Eating smaller portions and slowing down at mealtimes can sometimes help reduce symptoms.

Being Overweight

Excess weight, particularly around the abdomen, can place additional pressure on the stomach.

This pressure can increase the likelihood of acid reflux and heartburn. For some individuals, even a modest reduction in weight can lead to noticeable improvements in symptoms.

Stress and Anxiety

Many patients are surprised to learn that stress and digestive symptoms are often closely linked.

Stress may not directly cause acid reflux, but it can:

  • Increase sensitivity to stomach acid
  • Affect digestion
  • Disrupt eating habits
  • Make existing symptoms feel more severe

If you've noticed your heartburn worsening during busy or stressful periods, the connection may be stronger than you think.

When Should You Be Concerned About Heartburn?

Most cases of heartburn are not caused by anything serious. However, certain symptoms should always be assessed by a healthcare professional.

You should seek advice if you experience:

  • Heartburn more than twice a week
  • Symptoms lasting several weeks or months
  • Difficulty swallowing
  • Pain when swallowing
  • Unexplained weight loss
  • Persistent nausea
  • Vomiting
  • Black or tarry stools
  • Symptoms that don't improve with treatment

These symptoms don't necessarily indicate a serious condition, but they do warrant further investigation.

How Can Heartburn Be Investigated?

If symptoms are persistent or affecting your quality of life, a specialist may recommend diagnostic testing to identify the underlying cause.

One of the most effective investigations for ongoing heartburn is a gastroscopy.

During a gastroscopy, a small camera is used to examine the oesophagus, stomach, and upper digestive tract.

This can help identify:

  • Inflammation
  • Oesophagitis
  • Stomach ulcers
  • Hiatus hernia
  • Signs of chronic acid reflux
  • Other digestive conditions

Many patients find that understanding the cause of their symptoms provides reassurance and allows them to move forward with an appropriate treatment plan.

Simple Ways to Reduce Heartburn Symptoms

Although medical investigation may be necessary for ongoing symptoms, there are practical steps that may help reduce discomfort.

These include:

  • Eating smaller meals
  • Avoiding meals late at night
  • Limiting alcohol intake
  • Reducing trigger foods
  • Maintaining a healthy weight
  • Avoiding lying down immediately after eating
  • Elevating the head of your bed

These measures may help manage symptoms, but they should not replace professional assessment if heartburn is becoming frequent or persistent.

Don't Ignore Persistent Heartburn

Many people live with recurring heartburn for years, assuming it's simply part of life.

The truth is that persistent heartburn is often your body's way of signalling that something isn't quite right.

While the cause may be straightforward and easily managed, ongoing symptoms deserve proper attention.

Seeking advice early can help identify the cause, provide reassurance, and prevent symptoms from affecting your quality of life.

Why do I get heartburn every day?

Daily heartburn may be caused by acid reflux, GORD, dietary triggers, lifestyle factors, or another digestive condition that requires investigation.

Can stress make heartburn worse?

Yes. Stress can increase sensitivity to digestive symptoms and often makes existing heartburn feel more severe.

What foods commonly trigger heartburn?

Common triggers include spicy foods, fatty meals, coffee, alcohol, chocolate, citrus fruits, and fizzy drinks.

When should I worry about heartburn?

You should seek medical advice if symptoms occur frequently, don't improve with treatment, or are accompanied by weight loss, difficulty swallowing, or persistent nausea.

Can a gastroscopy help diagnose heartburn?

Yes. A gastroscopy is one of the most effective ways to investigate persistent heartburn and identify potential underlying causes.
