James is 50 years old and presents with a 1 month history of indigestion after eating heavy meals. He denies any change in bowel habit, rectal bleeding, weight loss, dysphagia or vomiting. He works in an Indian restaurant as a chef and admits to drinking 3-4 pints daily and is a non-smoker. He buys Aspirin to take on a daily basis as he is concerned about a family history of heart disease. Abdominal examination is normal and his observations are all within normal range. His BMI is 24.
Given his likely diagnosis what would be the next best step in his management?
