hi everyone
today we are going to talk about what to
eat before or after exercise or do you
have to eat before and after exercise
right that questions also come up
frequently in my diabetes practice I'm
an endocrinologist by trade and I love
treating patients with diabetes and I'm
hopeful that this video will teach you
something now let's go back to what type
of diabetes you have so if you are on
agents that does not cause low blood
sugar let's say you're on metformin only
or you're on metformin and Olympic or
metformin and trulicity metformin and
Jardine's the agents that does not cause
low blood sugar is generally okay and
you don't have to worry too much about
exercise the only time you really need
to worry about exercise causing low
blood sugars is when you are on an agent
such as a sulfonylurea glipizide
glyburide Gilliam up ride any of these
agents can cause low blood sugar either
during or after exercise that remember
any time you exercise your blood sugar
may drop during the exercise especially
if it is a prolonged exercise or a
longer exercise or it can drop within
the next 24 hours and that is because
any time you exercise the effect can
last up to 24 hours and many people do
not realize that so they go exercise in
the morning and later ten hours later
they may have a low blood sugar because
they took what they normally take with
the insulin and the same insulin works
much better on the days that you
exercise so you have to pay attention to
that part and what to do immediately
right before the exercise depends on how
much insulin you took before how long
before you took it and what your blood
sugar is at the time
right now so there's a lot of questions
to be answered so if you're on a
continuous glucose monitoring system
such as Dexcom freestyle libera or
whatever it may be and if you know how
to manage those devices like you need to
understand how the arrows work up arrow
down arrow diagonal arrow and you know
there are a lot of factors that play
into decision making and it may not be
very easy at all time so if you're not
very sure you may want to ask to someone
but that someone is not available to you
always is it no it's not so that's why
we came up with actually sugar and is
calm so you have the app and you can
even text from your cell phone and ask a
question what to do at this time and we
will assess your situation and give you
an immediate answer to prevent a problem
and that will also be at training for
you so in a similar scenario you will
know what to do but if you don't have a
trainer if you don't have a professional
helping you side by side at all times
during your life and during different
events during sickness during exercise
when you're in a party etc etc a lot of
things changes your blood sugar and can
give you unexpected results so your
blood sugar may be perfectly okay one
day and very high next day and to avoid
the scenarios you really need to be able
to tweak your regimen and understand how
medications work how your body reacts
anyway so the the so I will give you a
quick example let's say you are your
this is gonna be a simple example let's
say your blood sugar is 110 and you're
on once a day insulin so if you're going
to go to the gym for an hour it's not a
bad idea to consume a rapidly absorbed
carb and that's not necessarily you know
I'm not asking you to go eat dessert but
you can have a banana or something like
that that has thirty to forty grams of
carbs that can carry you through the
exercise if you are worried about and as
I said you're only worried about
low blood sugars during or after
exercise if you're unsafe anuria agents
or if you're on insulin if you have
taken insulin let's say two hours ago a
short-acting insulin in this case you
know that the short acting insulins or
you should know that the short acting
insulins actually lasts up to four hours
so we call that active insulin time so
if I took insulin a short acting insulin
two hours ago I have or I will have
insulin two more hours in my system and
if my blood sugars are already trending
low or it less than 120 130 and I know
it's gonna go down further because I
have insulin in my system so in that
case I would eat snacks before my
exercise and during the exercise if I am
exercising more than thirty minutes I
should stop and check my blood sugar and
see where I am and then once you do that
a few times and if your exercise pattern
is similar then you will understand how
your body is reacting so checking more
often is definitely helpful and then
after you exercise if you're starting
the new exercise regimen it is not a bad
idea actually to keep an eye on your
blood Sugar's every two to three hours
for the next 18 to 24 hours just to see
how your blood Sugar's are trending just
because if you are keeping the same diet
regimen and especially if you are trying
to lose weight you may end up having low
blood sugars unless you make adjustments
in your insulin or other medication
regimens again we don't expect you to
make very correct decisions with your
medications with diabetes and so many
factors contributing to it again ask
your doctor if they are available and if
you are one of our patients you know
you're going to hear back from us within
seconds or minutes after your text or
your call now with that being said if
your blood sugars are let's say 200
you may not have to worry too much about
it you can just go exercise and and then
see what happens maybe two hours later
but I wouldn't be too worried unless
you're going to a marathon and you're
gonna be exercising very intense
intensely then then you may want the
mantra more often but if you're gonna go
on a treadmill your blood sugar is 200
you don't have insulin in your system
that was recently taken then you don't
have to worry too much about that
now sometimes you will also notice that
your blood sugars are actually going
higher when you're exercising and that's
not uncommon so what happens when you
exercise your body creates this
adrenaline discharge it is a stress
response a temporary stress and
adrenaline goes up to try to come up
with is necessary blood flow through
your heart so your blood since
adrenaline is a hormone that goes
against the insulin for temporarily your
blood sugar may go up a little bit
higher but that's not going to last too
long
immediately after exercise your
adrenaline goes down and then you become
insulin sensitive and your blood sugar
may go a totally opposite direction so
again understanding your body how you're
responding check your blood sugar before
if it is on the low side eat a snack
check it again in the middle of the
exercise if it is more than thirty
minutes and then you can continue to
monitor after the exercise is done every
two to four hours and if you know how
your body is reacting and if you know
your routine you may not have to do that
every time you exercise but at least
initially to determine how you're
reacting to the exercise it is not a bad
idea
again continuous glucose monitoring
systems make the life a lot easier at um
news.com you're always there for you to
answer your questions and with that we
are going to conclude and we'll see you
next time
so if you have any questions ask for a
free consultation from sugar and be ziko
