the symptoms of hypoglycemia
such as irritability, nervousness,
anxiety, dry mouth, muscle tightness
in the neck and low back,
palpitations and so on.

Diabetics
quite often experience some of
these symptoms.
Insulin is the most important
hormone secreted by the beta cells
of the pancreas contained in the
Islets of Langerhans.

It promotes
glucose utilization by facilitating
the entry into the body cells of
glucose. It is also promotes protein
synthesis using amino acids to
make proteins inside body cell and
lipid storage in the form of triglycerides.

Insulin is a building type of
hormone and helps the body to
take in nutrients and utilize them.
It responds to glucose levels
rather than levels of other nutrients.

Unfortunately hypoglycemics
have too much insulin with the
result that too much sugar leaves
the blood and the brain is fueled by
what little is left. There is not
enough sugar in the blood to feed
the brain, resulting in tiredness,
vagueness in consequence of the
blood sugar levels going too low.
