A self-induced vomiting
B Purging
C Excessive exercise
D Use of appetite suppressants and/or diuretics. - distorted body image perception driven by an intense irrational fear of becoming fat, leading to a desire to remain at a low body weight
- amenorrhea (absence of minimum of 3 successive menstrual cycles) in women and loss of libido in men
- Puberty in boys and girls may be delayed if the onset of anorexia nervosa is prepubertal, but once recovery from illness is made, it will often progress normally.
bulimia nervosa
psychological illness that is characterised by frequent periods of binge eating followed by frequent periods of self-induced vomiting.
many also exercise vigorously
in extreme cases laxatives are also taken to increase purging.
bulimia sufferers are often of a normal weight so the condition can go undetected for years.
two types of bulimia nervosa
purging and non purging
purging type
sufferer is engaged with regular periods of self-induced vomiting, with the misuse of laxatives, diuretics or enemas
non purging type
engaged in other compensatory behaviours like excessive exercising or self induced starvation
- there are efforts made to reduce the effect of eating foods perceived as fattening in the form of:
A self-induced vomiting and other purging techniques
B alternating episodes of calorie restriction
C using appetite suppressants
D using thyroid preparations or diuretics
E people with diabetes may refrain from using their insulin treatment.
