What causes heartburn in a healthy 21 year old male with no heartburn history?
I was just wondering if anyone knows what causes heartburn in someone who has never had it before. I've had heartburn for a week now, with little relief. There is no change to my diet, although I am a coffee drinker. It has never given me heartburn before though. I am otherwise a healthy 21 year old male and I don't smoke or drink.
