Functional dyspepsia (FD), often referred to as non-ulcer dyspepsia, is a chronic disorder of sensation and movement in the upper digestive tract. Unlike other gastrointestinal conditions, FD presents without any visible structural abnormalities, making diagnosis and management particularly challenging. Affecting millions globally, it significantly impairs quality of life and daily functioning.
What Is Functional Dyspepsia?
Functional dyspepsia is characterized by persistent or recurrent pain and discomfort in the upper abdomen. It is diagnosed when these symptoms occur without any identifiable cause such as ulcers, inflammation, or cancer. FD is a subset of disorders known as disorders of gut-brain interaction (DGBI).
Primary Symptoms
- Epigastric pain or burning
- Early satiety (feeling full quickly)
- Postprandial fullness (uncomfortable fullness after meals)
- Bloating and belching
- Nausea without vomiting
Symptoms may fluctuate and are often exacerbated by stress, certain foods, or irregular eating habits.
Causes and Risk Factors
Primary Risk Factors
- Visceral hypersensitivity: Heightened sensitivity of the stomach lining.
- Motility disorders: Impaired movement of the stomach muscles.
- Gut dysbiosis: Imbalance in gut microbiota.
- Eosinophilic duodenitis: Inflammation due to immune cell infiltration.
Additional Risk Factors
- Anxiety and mood disorders
- Functional GI disorders (e.g., IBS)
- Food sensitivities or intolerances
- Allergic conditions or atopy
Diagnosis
Diagnosis of FD is clinical and often involves ruling out other conditions. Common diagnostic steps include:
- Medical history and symptom assessment
- Physical examination
- Endoscopy to exclude ulcers or malignancy
- Helicobacter pylori testing
- Gastric emptying studies (if motility disorder is suspected)
Treatment Options
Lifestyle Modifications
- Regular meals: Avoid skipping meals and eat smaller portions.
- Stress management: Mindfulness, yoga, and therapy.
- Sleep hygiene: Maintain consistent sleep patterns.
Dietary Adjustments
- Low-fat diet
- Avoid trigger foods: Spicy, fatty, and acidic items.
- Limit caffeine and alcohol
Medications
- Proton pump inhibitors (PPIs): Reduce stomach acid.
- Prokinetics: Improve gastric motility.
- Antidepressants: Low-dose tricyclics or SSRIs for visceral pain.
- H. pylori eradication therapy (if applicable)
Psychological Therapies
- Cognitive Behavioral Therapy (CBT)
- Gut-directed hypnotherapy
Prevention Strategies
While FD cannot always be prevented, the following strategies may reduce risk:
- Balanced diet and hydration
- Regular physical activity
- Avoid smoking and excessive alcohol
- Manage stress proactively

FD is a chronic condition requiring long-term management. Support groups, regular follow-ups, and personalized care plans can help patients cope effectively.
