Do I have an eating disorder? And if so, which one?

If I chew food and spit it out, weigh myself up to ten times a day (I know, I know), take 4-12 laxatives every day, take 2-4 diuretics every couple of days, eat about 500 calories or less a day, and constantly think about food, BUT am not underweight, even though I've had escalating issues with food for a couple years (a bmi of 20.5), and do not exercise, do I have an eating disorder? (Long sentence) I am not sure, because I think I technically have to be underweight to have one, and I am not sure what that would be even if I did. I used to be bulimic a year ago, but stopped. I still think I might be because of the laxatives and chewing and spitting, but I don't know.
SO, do I have an eating disorder, and if so, which one?

seems more like anorexia now. you dont need to be underweight to have an eating disorder! many poeple do and are OVERweight.

I think you know you do and it doesn't really matter what it is called. You do not have to be underweight to have an eating disorder. You need to talk to your doctor and get help. The laxatives and diuretics are extremely harmful and will cause severe problems in the future. You are not taking in enough calories to have your body function properly. The yo yo dieting messes up your metabolism. You need to talk to someone that can help you with your body image, and someone that can teach you how to eat properly.

you have anorexia. and you dont have to be under weight to have it. many over weight ppl hve eating disorders too. you dont hve to hve a specific body type for it. but because of this you should tell your doctor about it and if you want to lose weight he/she might be able to help you with it.

Still that is soo un-heathly ! You need to start eating more and gain weight so you can become more active and eat more heathy choices!!

you can have bulimia

i think you do. sounds like anorexia cuz you don't eat much.

Eating disorders start before you get underweight--that's why it's such a bad thing, because it's psychological, not just "Oh, let's lose 10 pounds then quit and stay at that weight." If you're taking laxatives and diuretics, you might want to go talk with somebody about the possibility of an eating disorder, especially since those drugs will end up hurting you in the long run (people tend to get dependent on laxatives, and some diuretics can really mess with your kidneys). And you need more than 500 cals per day just to maintain your metabolism, so by starving yourself you're not doing anything good for your body. (With the amount you're taking in and the amount you're forcing out, you've got nothing left, so that's technically anorexia, to answer the rest of your question.)
