Indigestion, also known as dyspepsia, is a common digestive symptom that causes discomfort or pain in the upper abdomen, particularly after eating. Many people experience occasional indigestion symptoms, but persistent or recurrent symptoms may indicate an underlying digestive condition that requires medical assessment.

Relevant Diagnostic Tests
Indigestion is not a disease itself. It is a symptom or group of symptoms affecting the upper digestive tract. Although many people associate indigestion with heartburn, the two are not the same. Indigestion can occur with or without acid reflux.
People describe indigestion in different ways, but common experiences include:
Accompanying Symptoms
Indigestion commonly occurs alongside:
For some people, symptoms develop occasionally after a large meal. For others, symptoms can occur daily and significantly affect quality of life.
The causes of indigestion symptoms range from harmless lifestyle factors to digestive disorders requiring specialist treatment.
Lifestyle & Dietary Triggers
Many cases of indigestion are linked to diet and lifestyle habits.
Common triggers include:
Certain medications can also irritate the stomach lining and contribute to indigestion, including:
Tip: Keeping a food and symptom diary may help identify personal triggers.
Functional Dyspepsia
Functional dyspepsia is one of the most common causes of persistent indigestion symptoms. In this condition, patients experience symptoms such as fullness after eating, upper stomach pain and bloating, despite no obvious abnormalities being found during investigation.
Symptoms may include:
Gastro-Oesophageal Reflux Disease (GORD)
GORD occurs when stomach acid repeatedly travels back into the oesophagus. Many patients experience both reflux and indigestion symptoms simultaneously.
Gastritis
Inflammation of the stomach lining can cause:
Peptic Ulcers
Ulcers affecting the stomach or duodenum may cause:
Coeliac Disease
This autoimmune condition can sometimes occur with indigestion, bloating and abdominal discomfort.
Irritable Bowel Syndrome (IBS)
Although IBS primarily affects the lower gut, some patients experience indigestion-like symptoms including bloating and early fullness.
Less Common or Serious Conditions
Less frequently, indigestion symptoms may be associated with more serious conditions.
Gallstones
Gallstones may cause:
Inflammatory Bowel Disease (IBD)
Conditions such as Crohn’s disease can occasionally cause upper digestive symptoms.
Stomach Cancer
Although uncommon, persistent new-onset indigestion, particularly in older adults, should always be assessed to exclude stomach cancer.
Pancreatic Conditions
Inflammation or disease affecting the pancreas can sometimes occur with upper abdominal discomfort and digestive symptoms.
Most episodes of indigestion improve without medical treatment. However, some symptoms require prompt assessment.
Red Flag Symptoms: Seek urgent medical attention if you experience any of the following:

Many people worry when digestive symptoms persist. A thorough assessment helps identify the underlying cause and determine the most appropriate treatment.
Initial Consultation
During your appointment, a gastroenterologist may ask:
A physical examination may also be performed.
Gastroscopy (Upper Endoscopy)
A gastroscopy examines the oesophagus, stomach and duodenum using a thin flexible camera, and can help diagnose:
Colonoscopy or Flexible Sigmoidoscopy
These tests may be recommended if symptoms overlap with lower bowel concerns.
Blood and Stool Tests
These may be used to identify:
Abdominal Ultrasound or CT scan
Imaging investigations can assess:
Treatment depends on the cause identified during assessment.
Self-Care & Home Remedies
Many patients improve with lifestyle changes, with helpful measures including:
Some people benefit from antacid medications available from pharmacies.
Medical & Prescription Treatments
Your specialist may recommend:
Proton Pump Inhibitors (PPIs)
These medicines reduce stomach acid production and are frequently prescribed for:
H2-Receptor Blockers
These reduce acid production and can help manage persistent symptoms.
Antibiotic Treatment
If Helicobacter pylori bacteria are identified, a course of antibiotics may be prescribed.
Other Medications
Depending on the cause, treatment may include:
Surgical or Specialist Interventions
While uncommon, some underlying causes may require specialist treatment such as:

Not necessarily. While indigestion and functional dyspepsia are common causes, early satiety can sometimes be associated with ulcers, gastritis and other digestive conditions.
Keep a record of symptoms, medications, dietary triggers and any previous test results. This information helps your consultant identify the most appropriate investigations.
Functional dyspepsia is a common digestive disorder causing symptoms such as fullness after eating, upper stomach pain, bloating and epigastric discomfort despite normal investigation results.
Eating smaller meals, avoiding trigger foods, reducing alcohol and caffeine, and taking antacid medication may provide short-term relief.
Occasional indigestion may last a few hours. Persistent indigestion lasting weeks or recurring frequently should be medically evaluated.
Most cases of indigestion are not serious and relate to diet, lifestyle or common digestive conditions. However, persistent symptoms or red flag symptoms should always be assessed by a specialist.
