How Can Acid Reflux Be Treated?

I m an 18 year old female standing at around 5 9 and 145 lbs, recently I have been experiencing heartburn and other forms of acid reflux alongside occasional constipation and constant burping. Last night I had sushi (restaurant prepared, high quality, non-deep fried) for dinner with a pot of black tea, and as I was walking into my local top foods after dinner stopped in my tracks at an all too familiar pang in my chest. I thought it was strange given that I normally experience symptoms like this after eating fried, fatty, or otherwise questionable foods, but never after a meal I would consider relatively healthy.
