###Human: What is causing hiatal hernia with chest pain? ###Assistant: Hi. I have gone through the reports of your endoscopy (attachment removed to protect patient identity), as per the endoscopy you do not have any evidence of cancer. Have you received the reports of biopsy? If so, please forward it. The medications you have taken are appropriate. If symptoms persist, may consider doing a high-resolution manometry. Continue the same medications. May add Gaviscon tablet after major meals for one week. Refrain from lying down for at least for two hours after food. Elevate head end of the cot by six inches. Restrict citrus fruits. Restrict tea and coffee to two cups per day.
