height decrese
cbc anemia leukopenia
ecg bradycardia
xray osteopenia
if the patient has amenorrhea..doesnt it affect lipid profile?
CBC..netropenia , X -ray - osteopenia,ECG- Prolong QT interval..
leaves 2 option.. Lipid porfile..inc cholesterol..coz Dramatic elevations in cholesterol are observed in cases of starvation.
This elevation may be secondary to (1) decrease in triiodothyronine (T3) levels, (2) low cholesterol binding globulin, and (3) leakage of intrahepatic cholesterol..!
Abt height..High Gh..so it may lead to early fusion of epiphysis & lead to dec height..!

Anorexia nervosa is an eating disorder characterized by failure to maintain body weight at or above 85% of ideal weight for age and height.
Findings indicative of anorexia nervosa include lanugo, or downy body hair, amenorrhea for three or more consecutive months, hypothermia, constipation, and hypotension.
Typically, anorexic patients develop their symptoms during their adolescence after the growth spurt, therefore the height (A) of the patient is likely to be normal.
CBC (Choice B) in anorexia nervosa may demonstrate anemia and or leukopenia.
ECG (Choice C) may show low-voltage T-wave inversion and flattening, ST depression, and prolonged QT intervals.
The most common cause of death in anorexia nervosa is cardiac arrhythmias due to hypokalemia.
Lipid panel (Choice D) may show hypercholesterolemia and elevated triglycerides.
X-ray examination (Choice E) may reveal evidence of early osteoporosis.
Anorexia nervosa is also characterized by family conflict, particularly with the mother, normal appetite, increased interest in food, decreased interest in sex, and excessive exercising.
