What are some red flags you are looking out for in a hx of dyspepsia
Hematemesis, Malena, weight loss
Helicobacter pylori infection is one of the leading causes of dyspepsia and PUD. It is also associated with gastric cancer and Cardiovascular disease.
As a GP, how would you screen for Helicobacter pylori?
How would you manage?
Although the gold standard is Antral biopsy and histology with CLO-urease testing…
Screen:
1) Urea breath test
2) Fecal antigen testing
(Remember serology is not useful)

What is the conservative management of dyspepsia
Lifestyle:
Reduce weight
Healthy diet avoiding precipitation by alcohol, coffee, chocolate, fatty foods.
Smoking cessation
