What is functional dyspepsia?
Functional dyspepsia is a common digestive condition that causes ongoing discomfort or pain in the upper abdomen (the area between the belly button and breastbone). It is called “functional” because the stomach appears normal on testing, but does not function as expected.

This condition is chronic, and symptoms may come and go over time.

What causes functional dyspepsia?
The exact cause of functional dyspepsia is not fully understood. Several factors may contribute:

  • Reduced stomach relaxation after eating, leading to early fullness and bloating
  • Increased sensitivity of the stomach nerves, causing normal digestion to feel painful or uncomfortable
  • Delayed stomach emptying
  • Low-grade inflammation in the upper digestive tract
  • Infection with Helicobacter pylori infection in some patients
  • Brain-gut interaction, where stress and emotions can worsen symptoms and symptoms can increase stress

Symptoms of functional dyspepsia
Symptoms may vary from person to person and often fall into two patterns:

Meal-related symptoms:

  • Feeling overly full after eating
  • Feeling full after eating only a small amount
  • Bloating after meals
  • Nausea

Pain-related symptoms:

  • Burning or pain in the upper abdomen
  • Discomfort that may or may not be related to eating

Other symptoms may include belching, nausea or occasional vomiting.

Diagnosing functional dyspepsia
Functional dyspepsia is diagnosed based on symptoms and by ruling out other conditions. Your provider may use criteria such as symptom pattern and duration, along with testing when needed.

Testing may include:

  • Upper endoscopy (EGD)
  • Testing for H. pylori infection
  • Blood tests
  • Gastric emptying study

These tests help ensure there is no structural cause for symptoms and help guide treatment.

Treatment for functional dyspepsia
Treatment is individualized based on your symptoms and may involve a combination of approaches.

Treatment options may include:

  • Treating H. pylori infection if present
  • Dietary and lifestyle changes
  • Acid-reducing medications
  • Neuromodulator medications (targeting gut-brain nerve signaling)
  • Prokinetic medications (to improve stomach emptying)
  • Herbal or complementary therapies
  • Brain-gut behavioral therapies

Diet and lifestyle changes
Many people benefit from simple dietary adjustments, including:

  • Eating smaller, more frequent meals
  • Limiting high-fat foods
  • Avoiding trigger foods such as spicy foods, caffeine, alcohol and carbonated beverages
  • Eating slowly and chewing thoroughly
  • Keeping a food and symptom diary

Stress and symptom management
The brain and digestive system are closely connected. Stress can worsen symptoms, and symptoms can increase stress.

Helpful strategies may include:

  • Regular physical activity
  • Good sleep habits
  • Relaxation techniques such as deep breathing, meditation or yoga
  • Counseling or therapy when needed
  • Medications for anxiety or depression if recommended

When to seek care
Contact your healthcare provider if you experience:

  • Unintentional weight loss
  • Persistent vomiting
  • Difficulty swallowing
  • Black or bloody stools
  • Symptoms that interfere with daily life
  • Symptoms that are not improving with treatment
