it's really common that we're doing
cases of hypo and hyperthyroidism we get
stuck when we're trying to explain to a
patient why your TSH is high in
hypothyroid and why your TSH is low in
hyper thyroid and we all talk positively
about negative feedback loops and things
and it gets very confusing one really
simple way to explain to a patient is at
elevation of the brain is constantly
talking to the thyroid all the time is
talking to it and how loud the brain is
talking is reflected by your TSH level
so without an underactive thyroid or
hypothyroidism your thyroid gland down
here is not working very well so your
brain is starting to shout really loud
to it remember is shouting loud so your
TSH level goes up and that's why in an
underactive thyroid you don't raise TSH
level if you look at hyper thyroid where
your your thyroid gland is already
working really fast your brain starts to
become really quiet because the thyroids
overworking so it stops talking it
becomes quiet and that people TSH level
goes down or low so it's worth thinking
about until the patient of the brain is
constantly talking to the thyroid and
depending on how fast this is working
your brain either gets really loud I
know
under active thyroid or it goes really
quiet in an overactive fire and that
relates to your TSH level helps
