What!

I don't think there's anybody that can answer this confusing question.

I mean come on, nitrogen loss due to a hormone!

Please post the answer with explanation if you can

This is a guess, but Cortisol? Since it's the number one stress hormone and has catabolic function it would break down the proteins in the body and increase nitrogen excretion as urea. Also explains y burn patients tend to suffer from renal stones and their dietary intake has to be monitored.

Considering burn patient as a person with a stress.... cortisol....

@ gnnd: thyroxine causes nitrogen loss this is why hyperthyroid pts have weight loss

the answer is cortisol. good guess housewannabe. just relate stress (burn ptt) with nitrogen loss.. stress causes highly elevated cortisol level, even when we are normally stress or angry
