A 45 year old male presents with new onset dyspepsia to the GP surgery. He is an ex-smoker with a BMI of 25 and consumes 4 units of alcohol a week. He denies weight loss, dysphagia, change in bowel habit, rectal bleeding, or abdominal pain. He has already avoided trigger foods and attempts to eat smaller meals, but given minimal change in his symptoms he has now come to see his GP.
