Find out all about fever. 11:32 What to do if I have fever in July 2020. If you’ve found this video helpful please share. If you have a topic that you want me to cover …
hi everyone
i'm April Rolle your ER doctor online
and today's discussion is about
fever it's called fever 101
so before i start talking about
fever i'm actually going to discuss
normal body temperature so normal body
temperature
is around 98.6 degrees
fahrenheit give or take sometimes
usually
97 to 99 is where
the body fluctuates normally and
also um just in general
the body tends to change its temperature
throughout the day there are certain
things
such as uh time of day
circadian rhythm which kind of is
um throughout the day like rhythmic
changes that happen
as the day goes on certain patterns
happen at certain times for instance a
sleep schedule
is an example of what follows the
circadian rhythm
um other things that affect normal body
temperature
for women depends on which phase of your
menstrual cycle you're in in the luteal
phase you're
tending to have a normal uh basic
basal body temperature so there are a
lot of things
throughout the body that affect your
normal temperature
and your body has a system
kind of like a thermostat where it
actually sets
what your temperature is at so now that
we
kind of know all about normal
temperature let's talk about
what is a fever
a fever by definition
is when your body temperature
is at 38 degrees celsius
or what we're more common with
fahrenheit 1.4
degrees fahrenheit a lot of people will
come in
to the er and they'll say you know i've
been having fever
and when i when i was a newbie i just
take it as okay the person says they're
having fever
but now i know to ask what
is your temperature and a lot of the
times actually
people are saying that they have fever
when their temperature
is 98 or 99 and
they actually don't have a clue about
what is the definition of a fever and
what makes
it you know be classified that you are
having fever
and again that number is 100.4
degrees fahrenheit that is what
classifies
having a fever so let me discuss some
other things
that i wanted to talk about here um
so how would you even know that you have
a fever
sometimes people you know they'll just
say oh i feel
i feel real warm but actually in order
to tell whether or not you have a
you know fever you actually have to take
your temperature so there are a lot of
ways to take your temperature
you know they have the infrared things
where you don't even have to touch your
body
they have the wands that actually touch
across your forehead
um the ones that go in the ear oral
thermometers that you have to put under
your tongue
and also rectal thermometers most likely
are most commonly used on infants
the rectal thermometers
so to talk about thermometers and how
you take your temperature
actually the rectal temperature is
the most accurate though that's not the
one that we
generally take all the time it is the
most accurate
and between the rectal oral and the
um temperature that's taken in the ear
um
the rectal is the most accurate then the
oral is
usually about within one degree less and
then
the ear temperature is even one degree
less
usually than the oral so sometimes that
can be misleading because
if you're taking
your temperature through your ear it may
not be as high as it actually is now i'm
not saying
you have a fever like oh my temperature
was
uh 99 on my ear so that means my rectal
temperature
is 101. that's it's not exactly
true but in general the rectal
temperature
is a better uh gauge of what your core
body temperature is
so um hi linda thanks for joining
the next thing that i want to talk about
fever is
how long some people are asking how long
are they going to have a fever
so a lot of the times when you do have
fever
it's because some type of process is
going on
in your body usually it is some type of
illness
you know commonly you have like an upper
respiratory infection
or a stomach bug or something like that
you generally have a fever with it and
that is an
indicator because the body has certain
things
called pyrogens and that basically means
that those are components in your body
that produce fever so when someone is
sick
and your body is trying to combat
whatever
illness is happening it is
the pyrogens are basically increasing
your temperature
and you are getting fever so the length
of time
that you will have a fever usually
correlates to
how long you're sick some people their
fever goes away before they fully get
over
like an upper respiratory infection or a
stomach bug or something like that
but you can actually have
fever for the length of the actual
illness so
it just varies um it varies with you
know whatever
illness you're having it varies with you
know what processes are going on
in your body to actually combat the
illness and
also at baseline what is your body's
condition are you
a really sickly person are you
immunocompromised meaning
that your immune system has been
compromised
by either um you
things that can do that if you are a
transplant recipient those people are
usually
on anti-rejection medications which
make them immunocompromised also people
on chemotherapy
are immunocompromised people who have
hiv
are immunocompromised and there's a ton
of other
conditions where you are
immunocompromised so all of these things
play into um when you're having a fever
plays into your illness
it's a factor of how long you will
actually have fever
so another thing um what can you do
when you have fever when you have fever
there are medications that you can take
to bring your temperature down
and you you already know what these are
these are
tylenol or acetaminophen and anything in
the tylenol acetaminophen
family because i know in different
countries uh is known as paracetamol
and various other names but basically
the generic form acetaminophen
that is a medication that is used to
bring your fever down
also ibuprofen
other known as underbrand names advil
motrin those bring the fever down
within that category of non-steroidal
anti-inflammatory medications which
uh ibuprofen motrin and advil are
that category of nsaids also includes
a leave and a leave also can bring the
fever down
so other things that you can do
while you have a fever it's kind of like
um it seems counterintuitive but you
know
people when they get a fever sometimes
they get chills they're very cold and
they start
covering you know piling on piling on
the blankets
and that's actually not what you want to
do you want to
try to not increase your
body temperature as much as because your
body already is doing what it
what it does it's you know going to work
for you
it's increasing your temperature it's
doing several processes
in the body and i also want to talk
about that
um you can think of this as
um you know if you go
you know take a run or you go to the gym
or
you know you do some type of exercise
you feel your body temperature
getting uh higher you start to sweat
so it's kind of like that with you know
all the cells and molecules and organs
in your body
combating illness for you they are
working it out
so they are increasing the temperature
so
that is kind of you know if you want to
think about it like that that's kind of
what's happening
when you're having a fever so again
what to do when you have a fever you can
take tylenol
you can take ibuprofen um you can
you know make sure you're staying
hydrated because as
your body is combating the illness or
whatever for you
you want to stay hydrated another thing
which is not exactly fever but it is
a um it's an instance where you may have
an
elevated temperature is hyperthermia
and that is when you're not having a
fever because you're sick and your
body's
producing a fever you're actually just
having an
increased temperature maybe because
you've been outside in the sun all day
you've been working outside all day
and actually you're just overheating
that is a very very important
time to take in adequate hydration
because
you're basically um
everything is evaporating you know
you're sweating you're losing a lot of
fluid
you're getting dehydrated so it's really
important in that instance of
increased temperature um to drink a lot
of water because
that can lead to heat stroke passing out
a whole bunch of other things
so let me see if i have anything else on
here that i wanted to cover
about fever
i don't see anything here but
uh i do want to address the last thing
that i want to talk about fever
what to do if you have a fever yeah you
can take tylenol but
it is 2020 we are still in a pandemic
COVID 19 or coronavirus is still
going around so if you have a fever
during this time you definitely may have
COVID 19
so what to do what we've already been
telling you to do
isolate quarantine wear a mask
wash your hands for at least 20 seconds
at a time
um not even social distancing for you
you need to be quarantining at home if
you have a fever
you need to be at home you need to be
isolating because you can have coverage
you can be spreading it
to family members or friends so that
in this instance of July *2020
if you have a fever what to do please
isolate
please keep your people safe um and get
yourself tested wear a mask
go get yourself tested and if you do
have coconut 19
stay home stay hydrated get some rest
eat a well-balanced diet and make sure
you are
taking care of yourself if you start
having any shortness of breath or you
know
feeling in a way that you know something
is wrong you need to get to a hospital
please do go to the er and make sure
that you are taking care of yourself
i'm glad that you all decided to
join this live with me to discuss fever
101 what to do
what does it mean what is fever how do i
know i have fever
I hope that i've answered all of your
questions
thank you for joining me. Be blessed and
stay healthy!
