A 2-month-old boy is brought to the physician because
of a 6-week
history of persistent diarrhea and vomiting, most
pronounced after formula
feedings. He has had a 113-g (4-oz) weight loss since
birth. He
currently weighs 3100 g (6 lb 13 oz) and is 51 cm (20
in) in length. He
appears irritable. Examination shows jaundice. The
lungs are clear to
auscultation. No murmurs are heard. The liver is
palpated 2 to 3 cm
below the right costal margin, and the spleen is
palpated 1 to 2 cm below
the left costal margin. Laboratory studies show:


Serum
Glucose 35 mg/dL
Bilirubin (total) 2.3 mg/dL
Urine
Glucose negative
Reducing substances 3+

Which of the following is the most likely mechanism of
these findings?

A
) Decreased gluconeogenesis

B
) Decreased insulin secretion

C
) Increased glucagon secretion

D
) Increased gluconeogenesis

E
) Increased insulin secretion

F
) Insulin resistance

Decreased gluconeogenisis, i think thats a right answer,because the presentation is suggestive of heriditary galactosemia which is characterised by improper conversion of galactose to glucose,what do you say sarika.i put A in exam.

i put A too but now i think its galactosemia which also has reducing susbtance in urine but...none of teh choices go with it...also Glucose 6 phosphatase which was my initial diagnoses wouldnt prsent with vomiting right after feeding they show severe fasting hypoglycemia.....si im confused
