I starve all day, only an apple, then binge and purge alot. am i anorexic, bulimic or both. 5'3" and 80lbs and take laxatives to prevent water weight?

Bulimic: You have symptoms of bulimia nervosa. The best way to address this is to start eating 5 SMALL meals a day & control your portions. Eating one apple in AM, and then starving all day increases likelihood of binge-eating in the evening.

Anorexia: it sounds like both. You need to see a mental health provider t]who understands the treatment of anorexia and bulimia. One of the dangers beside damage to your body from lack of nutrition is electrolyte imbalance which can be fatal. Please seek out treatment.

Bulimia: Bulimia classically is associated with binging and purging, whereas anorexia is a general fear of eating entirely. Both of these disorders have to do with an altered perception of body image, and many people find great comfort in seeing a trained psychologist and/or psychiatrist to discuss their life experiences. I suggest you see a doctor ASAP, as this can threaten your health significantly

Need help: I'd say you mainly qualify as bulimic since you do admit to serious binging and purging AND the excessive use of laxitives.You are very seriously underweight at 80lbs and 5'3",and you are doing very serious damage to your body by continuing with this behavior.It will eventually catch up to you and cause you very serious problems.I strongly urge you to seek help and good help DOES exist.All my best
