I am 43 now,in my early 20's I was very anorexic,weighing only 56 lbs when I was put in hospital.I was in there for 5 months,with outpatient therapy for over a year.Basically for me it came down to either living or dying.Without help I would of died.You need professional help to get thru thisand a very strong determined mind that you want to get better and live.Please seek help ,you can't go thru this alone.If I can help in any way please let me know.

Serious anorexia (eg. Anorexia nervosa) is actually a systemic
vascular problem also called multiple system atrophy. Other
symptoms include insomnia, hypotentosion, orthostatic-intolerance
which all lead to a diagnosis of arterial tone loss due to vascular and
organic changes. The underlying medical condition common with
several other (improperly) so called "mental illnesses" is the
"endothelial dysfunction". Only gene therapy in very young people
can give them a change to survive.

Do not believe that it is cause by bad habits or cognitive impairment.
Hunger, like breathing, is not much influenced by the cognitive
function. Their body gets wasted because they were born with
significant arterial abnormalities and their body cannot be nourished
and oxygenated regardless how many calories they eat.

that is bullsh*t, actually

Can you explain why the posting you reacted to is bull?
You gave no details and no reason why the two medical conditions
mention by the other guy have nothing in common.
Otherwise, we will have to take you word for granted even if your
posting contains words that are probably filtered out in this forum.
