A 40-year-old, formerly obese woman presents to her physician. She was very proud of having lost 80 lbs. during the previous 2 years, but now noticed that her "hair is falling out." On questioning, she reports having followed a strict fat-free diet.
Her alopecia is probably related to a deficiency of which of the following vitamins?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin E
E. Vitamin K

vit A excess would cause alopecia.. rite?
with 2 yrs of fat free diet.. she would have much bigger problems to worry about than just losing hair.
if i had to, i would guess vit. C before the fat soluble vitamins.
biotin (b vit.) is a good answer to look for in the choices.. if they provide it.

Where did you get that idea. lets us suppose even if she was a candidate for PCOD she lost weight which is quite contary to PCOD and she followed a fat free diet

Not sure, 'cause too much Vit. A causes alopecia.
Would have to go with Vitamin E since people take E supplements for hair loss.

The correct answer is A.
While it is hard to develop a deficiency in oil-soluble vitamins (A, D, E, K) because the liver stores these substances, deficiency states can be seen in chronic malnutrition (specifically chronic fat deprivation) and chronic malabsorption. Vitamin A is necessary for formation of retinal pigments (deficiency can cause night blindness) and for appropriate differentiation of epithelial tissues (including hair follicles, mucous membranes, skin, bone, and adrenal cortex).
Vitamin C (choice B), which is water soluble rather than oil soluble, is necessary for collagen synthesis.
Vitamin D (choice C) is important in calcium absorption and metabolism.
Vitamin E (choice D) is a lipid antioxidant that is important in the stabilization of cell membranes.
Vitamin K (choice E) is necessary for normal blood coagulation.
