Acid Reflux/Bulimia? Please!?

This year I became bulimic.. When I started I would throw up my food atleast once a day. Then I stopped for a few weeks, and would maybe only throw up once a week or less. Recently I started throwing up again, but maybe only once a day or every other day. I never had any side effects.

A few days ago though, I noticed that my throat felt like it was burning, especially when I chew gum or drink soda, coffee, etc.

Would this be acid reflux? Or could it be my bulimia?

It seems strange to me that bulimia would start wearing away at my esophagus after I hadn't thrown up for a few weeks and then started again.

Thanks for any help!

In answer to both of your questions... Yes!
As you already know bulimia wears down the esophagus causing pain. It also causes acid reflux. You have a little valve between your stomach and esophagus that opens to allow food into the stomach and then closes to keep stomach acids and food to come back up. After time of forcing the valve open by vomiting, it becomes damaged and cannot close all the way allowing stomach acids to travel up the esophagus causing the pain. Chewing gum and drinking causes the stomach to produce acid in preparation of receiving food to digest, so this is why these activities make it worse.
I don't want to sound preachy, but this is only the tip of the iceberg as far as complications of bulimia. Please get some help before you kill yourself.

I really hope you are getting professional help for your Bulimia.
The constant flow of stomach acid up your esophagus and the abnormal amount of vomiting,even for a short period, can damage the sphincter muscle, at the top of your stomach, (it is usually called "erosion") so that it does not close completely any more, so that the acid in your stomach is constantly rising, causing more damage, you need to have a proper diagnosis done, and you will then need an acid reducing medication, FOR THE REST OF YOUR LIFE, I am on one because of damage done when I was on total life support during a life threatening illness, the feeding tubes and respirator damaged mine. If left untreated the acid reflux can cause ulceration of the esophagus, which can lead to possible cancer.
