Every person reacts somewhat differently to specific food groups. To track what foods worsen your symptoms, keep a food journal. In this journal, you should keep track of what you eat, the time you ate, any activity that worsened or made the heartburn better, and indicate which days you have heartburn symptoms. Over time, you will be able to correlate the offending foods with heartburn events. Print this and take this with you to your next doctor's appointment to discuss possible causes of heartburn you may be experiencing.
