UNINVESTIGATED DYSPEPSIA (UD)
• Dyspeptic symptoms in people who have not yet undergone specific diagnostic investigations.
Thailand Dyspepsia Guidelines 2018
![Page 9: FUNCTIONAL DYSPEPSIA - seminar.kkh.go.th](https://reader030.vdocuments.site/reader030/viewer/2022012703/61a583301278e25659781a7a/html5/thumbnails/9.jpg)
FUNCTIONAL DYSPEPSIA (FD)
• Dyspeptic symptoms cannot be explained by a routine clinical evaluation, including endoscopy, and there is no evidence of Helicobacter pylori infection.
• 2 subcategories:
(1) Postprandial distress syndrome
Postprandial fullness and early satiation (related to meal).
(2) Epigastric pain syndrome
Epigastric pain and epigastric burning (not related to meals).
Thailand Dyspepsia Guidelines 2018

FUNCTIONAL DYSPEPSIA (FD)
• The worldwide prevalence of UD varies from 7% to 34%, with a pooled UD prevalence from 21 Southeast Asian studies of 21.6%.
• In Asian populations, the risk of malignancy associated with UD is approximately 1.3% (95% CI, 0.80-2.10).
• Secondary dyspepsia was identified in 18% of UD patients after undergoing an endoscopy in Asian countries.
• In Thailand, 60-90% of patients with dyspepsia are eventually diagnosed with FD
• FD is a benign but chronic condition that often fluctuates and is sometimes recurrent.

ALARM FEATURES
• Evidence of upper GI bleeding hematemesis, melena, maroon stool, or iron deficiency without other causes.
• Early satiety.
• Unexplained weight loss (>10% body weight).
• Persistent vomiting due to an unknown cause (defined as vomiting > 10 times in 24 hours or vomiting after each meal).
• Family history of upper GI cancer in a first-degree relative.

Refractory functional dyspepsia
• FD that has continuous symptoms for at least 8 weeks and has been unresponsive to at least 2 medical treatments.*
• The guidelines for FD in the Asia-Pacific region and the United States of America (USA) recommend changing to a different drug if adequate therapeutic efficacy has not been achieved after 4 weeks of treatment.
* Miwa H. et al. J Gastroenterol 2015;50:125-139.

Management of Refractory FD
• H2-RA if PPIs have failed.
• Combination of acid suppression with a prokinetic agent.
• Combination of drug therapy with psychological treatment.
• Adjusting the dose of a TCA, prescribing an antipsychotic drug such as levosulpiride, or adding an anxiolytic.
• The combination of an antidepressant with pregabalin or gabapentin is yet another option that appears to relieve pain.
• Opioids have no therapeutic role and should be avoided because of the risk of dependence.

Dietary recommendations for patients with functional dyspepsia.
• Eat slowly and regularly.
• Decrease fat intake.
• Try to observe a diet that is more similar to a Mediterranean diet or increase
the intake of fresh foods and decrease the intake of ultra-processed foods.
• Decrease coffee and alcohol consumption.
• A gluten-free diet and a low-FODMAPs diet could be tested over a short time
period (4–8 weeks) and must be stopped if there is no efficacy.
• Be careful in providing strong recommendations to obsessive patients, and
avoid the recommendation of very restrictive diets.
