This on anorexia nervosa is from Wikipedia - Sounds pretty correct.
Anorexia can certainly be deadly, all-consuming, paralyzing.

Anorexia nervosa is a psychiatric diagnosis that describes an eating
disorder characterised by low body weight and body image distortion
with an obsessive fear of gaining weight. Individuals with anorexia
often control body weight by voluntary starvation, purging, vomiting,
excessive exercise, or other weight control measures, such as diet
pills or diuretic drugs. It primarily affects young adolescent girls
in the Western world and has one of the highest mortality rates of any
psychiatric condition, with approximately 10% of people diagnosed with
the condition eventually dying due to related factors.[1] Anorexia
nervosa is a complex condition, involving psychological,
neurobiological, and sociological components.[2]
Anorexia is a life threatening condition that can put a serious strain
on many of the body's organs and physiological resources. A recent
review of the scientific literature outlined a number of reliable
findings in this area.[3] Anorexia puts a particular strain on the
structure and function of the heart and cardiovascular system, with
slow heart rate (bradycardia) and elongation of the QT interval seen
early on. People with anorexia typically have a disturbed electrolyte
balance, particularly low levels of phosphate, which has been linked
to heart failure, muscle weakness, immune dysfunction, and ultimately
death. Those who develop anorexia before adulthood may suffer stunted
growth and subsequent low levels of essential hormones (including sex
hormones) and chronically increased cortisol levels. Osteoporosis can
also develop as a result of anorexia in 38-50% of cases,[4] as poor
nutrition leads to the retarded growth of essential bone structure and
low bone mineral density.
Changes in brain structure and function are early signs of the
condition. Enlargement of the ventricles of the brain is thought to be
associated with starvation, and is partially reversed when normal
weight is regained.[5] Anorexia is also linked to reduced blood flow
in the temporal lobes, although since this finding does not correlate
with current weight, it is possible that it is a risk trait rather
than an effect of starvation.[6]
