Functional Dyspepsia

What is it?

Functional dyspepsia, also known as non-ulcer dyspepsia or indigestion, is a chronic disorder of sensation and movement in the upper digestive tract. It causes persistent or recurrent pain and discomfort in the upper abdomen without an identifiable cause on standard diagnostic tests.

Common Symptoms

• Bloating or feeling full shortly after eating
• Upper abdominal pain or discomfort
• Nausea
• Belching
• Lack of appetite
• Early satiety (feeling full after eating only a small amount)

What can I do?

1. Eat Smaller Meals: Have smaller, more frequent meals to avoid overwhelming your digestive system.
2. Avoid Triggers: Limit spicy foods, fatty foods, alcohol, and caffeine which may worsen symptoms.
3. Reduce Stress: Stress and anxiety can exacerbate digestive symptoms — try relaxation techniques.
4. Quit Smoking: Smoking can worsen indigestion and delay gastric emptying.
5. Maintain a Food Diary: Identify patterns and triggers by tracking your meals and symptoms.

Common Medical Treatments

• Antacids or acid suppressants (e.g., PPIs or H2 blockers)
• Prokinetic agents (to enhance gastric motility)
• Low-dose antidepressants (to manage gut-brain sensitivity)
• Helicobacter pylori eradication therapy (if tested positive)
• Psychological support or therapy for associated anxiety or stress

When to Consult Your Doctor

• If symptoms persist for more than a few weeks
• If you experience unexplained weight loss, vomiting, or difficulty swallowing
• If over-the-counter medications do not relieve your symptoms

Remember

Functional dyspepsia is a real and often frustrating condition, but it can be managed with lifestyle changes, medication, and support. Working closely with your GP or gastroenterologist can help improve symptoms and quality of life.
