is switching between periods of undereating and overeating and never having a normal appetite/eating patter considered disordered eating? and is/can it be related to bpd??
Disordered eating includes behaviors that are common features of eating disorders, such as:
Chronic restrained eating.[1]Compulsive eating.[1]Binge eating, with associated loss of control.Self-induced vomiting.[2]
Disordered eating also includes behaviors that are not characteristic of any eating disorder, such as:
Irregular, chaotic eating patterns.Ignoring physical feelings of hunger and satiety (fullness).[1]Use of diet pills.[3]Emotional eating.[4]Night eating.[4]
The rates of eating disorders amongst those with personality disorders are much higher than the general population. Interestingly, some 30 to 38 percent of patients with eating disorders have an axis II disorder that is diagnosable. [...] Borderline personality disorder and co-occurring anorexia nervosa has a prevalence of 25 percent. Bulimia nervosa and BPD have a 28 percent prevalence rate, and these are higher than the overall rate of personality disorders in the general population, which ranges from 5 to 10 percent.

Because borderline personality is characterized by intense fears of abandonment, identity disturbance symptoms, these features are likely to shape the co-occurring eating disorder. For example, the impulsivity inherent in BPD may be displayed in binge eating episodes. Self-induced vomiting and the abuse of laxatives are damaging behaviors that demonstrate self-harm.
Researchers view eating-disordered behaviors in those with BPD as attempts to modify food intake, and thus alter body shape; and as behaviors through which individuals with BPD act out self-injurious tendencies using food issues as a platform. Binging fills an individual, and thus quells the chronic feelings of emptiness that typify this disorder. Purging causes fatigue, which combats affective swells and the anger experienced by those with BPD. It is clear that BPD could readily manifest in disordered eating given the traits inherent in the disorder.
