Nitrogen Balance Calculator
Nitrogen Balance (N balance) is the difference between
the dietary intake of nitrogen (mainly protein) and its excretion
(as urea and other waste products). Healthy adults excrete the same
amount as is ingested, and so are in N equilibrium.
During growth and tissue repair (convalescence) the body is in
positive N balance, i.e. intake is greater than loss and there is
an increase in the total body pool of protein. In fevers, fasting,
and wasting diseases the loss is greater than the intake and the
individual is in negative balance; there is a net loss of protein
from the body.
