Anorexia is known to cause hair loss. Hands shaking may be due to purging. To be considered bulimia there needs to be bingeing episodes and compensatory behaviors, such as, vomiting, excessive exercise, laxative abuse, etc. The following is the DSM IV TR criteria for Bulimia Nervosa, purging and nonpurging type: Recurrent episodes of binge eating characterized by both: Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than most people would eat during a similar period of time and under similar circumstances A sense of lack of control over eating during the episode, defined by a feeling that one cannot stop eating or control what or how much one is eating Recurrent inappropriate compensatory behavior to prevent weight gain Self-induced vomiting Misuse of laxatives, diuretics, enemas, or other medications Fasting Excessive exercise The binge eating and inappropriate compensatory behavior both occur, on average, at least twice a week for 3 months. Self evaluation is unduly influenced by body shape and weight. The disturbance does not occur exclusively during episodes of anorexia nervosa.
Purging type: During the current episode of bulimia nervosa, the person has regularly engaged in self-induced vomiting or the misuse of laxatives, diuretics, or enemas. Nonpurging type: During the current episode of bulimia nervosa, the person has used inappropriate compensatory behavior but has not regularly engaged in self-induced vomiting or misused laxatives, diuretics, or enemas.
