well lets remember what these two mean
Anorexia: An eating disorder causing people to obsess about weight and what they eat. (also purge)
Bulimia: A serious eating disorder marked by binging (purge), followed by methods to avoid weight gain.
so keeping that in mind...
skin and bone appearance - both
loss of menstrual periods - both
low blood pressure - anorexia
low body temperature - anorexia
constipation - both
swollen salivary glands - bulimia
blood potassium imbalance - anorexia (I THINK!)
Esophageal tears - Bulimia
immune dysfunctions - Bulimia
I REALLY HOPE THIS IS ALL RIGHT! lol
but hopefully it helped :)
