A widespread condition
related to nutrition
is lactose intolerance
that is in essence
the inability to digest and assimilate
the milk sugar-lactose-the substrate
that is acted upon by lactase-
the specific enzyme
over a period of time.
This may happen suddenly
and generally
at any age most unexpectedly.

Lactose intolerance
is caused by the absence
of the enzyme lactase
that breaks down lactose
to the simple sugars-
glucose and galactose.
The condition may be
secondary,  congenital,
or developmental.

Secondary lactose intolerance
invariably has its occurrence
related to a gastrointestinal infection
and its disappearance
is linked to the causative factor’s correction.
This type of intolerance-
(certainly a nuisance)
is reversible
if we are a bit careful.

Congenital lactose intolerance,
an inherited form of intolerance,
is a rare genetic  abnormality
that one can unearth
soon after an infant’s birth.
This need not cause any fear
as it lasts only half a year.

Developmental lactose intolerance
also known as primary  intolerance
is one wherein the enzyme synthesis
is progressively less
during childhood
and this persists into adulthood.
