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.
If you've felt fatigued or unusually exhausted, consider whether you have anemia. Anemia is a medical condition where your body does not have enough red blood cells to function properly. Whether your body isn't producing enough red blood cells, red blood cells are being destroyed by your body, or the anemia is caused by another medical condition, see your doctor for a diagnosis. While you'll need to follow the specific treatment regimen provided by your doctor, you may also need to take supplements, change your diet, and use medications.
