does ozempic and wegovy actually cause blindness?
the news and people are in a frenzy right now with
0:15
the new research that has come out showing a
stronger association with developing a serious
0:20
eye condition called an NAION or a nonarteritic
anterior ischemic optic neuropathy. it's a type of
0:30
eye stroke that can cause permanent blindness so
what's actually in this research what does it mean
0:35
for you and with this and previous research I'm
actually going to go over three different ways
0:40
these types of medications can actually change
your vision let's focus in ozempic or semaglutide
0:46
has been a booming prescribed medication for
type 2 diabetes and has an added side effect
0:52
benefit for weight loss and so now it is commonly
prescribed off label to help with weight loss and
0:59
this is where we go comes into the picture they
actually took that same semaglutide changed the
1:04
dosage repackaged it and actually now can be
prescribed for weight loss is actually FDA
1:09
approved for weight loss and how these medications
work it helps secrete a hormone gp1 that makes you
1:15
feel more full when you're eating so it kind
of acts like an appetite suppressant and at
1:19
the same time can increase your insulin which
can decrease your blood sugar so in the study
1:25
for the people that take these medications there
was a significant increase in the Association of
1:31
developing an NA people with diabetes four times
more likely and people with obesity over seven
1:38
times more likely so what exactly is an ni and
how bad is this like I said before it is a type
1:45
of an eye stroke where blood flow is restricted or
blocked for whatever reason to the optic nerve in
1:51
the back of the eye and when this happens it can
cause a sudden loss in Vision that you don't even
1:58
feel it's painless and fact a lot of times the
more common way people notice this is actually
2:03
when they wake up and all of a sudden they notice
maybe they're closing one eye cuz they're rubbing
2:07
the sleepies out and they'll notice that in that
eye half of their vision is gone dimmed out blurry
2:13
and it's usually the bottom half of the vision and
it's commonly referred to as an altitudinal Vision
2:20
defect now it's definitely more common to have it
happen in one eye you can have it happen in both
2:24
eyes but that is pretty rare and this can actually
severely affect someone in their day-to-day activ
2:30
ities walking up and down steps they're more
prone to tripping over things might make it
2:34
more difficult for driving seeing the dashboard
seeing the road seeing if there's something on the
2:39
road and so this can be a very serious condition
and the thing that's really unfortunate is that
2:44
there's not a treatment for an NA people that get
this vision loss likely will not have any recovery
2:51
from it and will be permanent now we want to make
two important notes from this study number one
2:57
they are not claiming that ozempic or wegovy is
causing an NAION. it's not causing this blindness
3:05
they can't make that claim but they are showing
that there is a stronger Association for people
3:11
that take this medication and developing this eye
condition number two a lot of times these people
3:16
that are taking these medications are already in a
category that are at a higher or increased risk of
3:22
developing this type of an eye stroke this can
include obesity people with diabetes and high
3:27
blood pressure the second way these medications
can cause a change in Vision or vision loss is
3:34
sometimes when people are put on these medications
it can cause a sudden drastic decrease in blood
3:40
sugar which can be good but for some reason can
actually cause some diabetic retinopathy to show
3:47
up or worsening diabetic retinopathy at least
at first diabetic retinopathy is usually when
3:52
the blood vessels in the back of the eyes will
pop or leak fluid sometimes we'll see bleeding
3:58
in the back of the eyes or sometimes we'll see
these things called cotton wool spots areas of
4:04
the retina that aren't getting enough oxygen
and sometimes some fluid that's in there might
4:09
accumulate and cause some edema or swelling and
definitely change the vision causing distortions
4:16
and blur now this is not unique to a zic or W
goie it's also found with other type 2 diabetic
4:22
medications for helping control blood sugar now
all these findings from this type of research does
4:28
show that in the the long run it is better for
overall health and Eye Health it is kind of unique
4:36
that at first when you start in the medication it
can cause more diabetic retinopathy so you just
4:41
want to work really carefully with your eye doctor
and your primary care doctor that's treating your
4:46
diabetes so you can just watch your overall Eye
Health in combination with your overall health
4:52
because a lot of times in the research it shows
in the long run it should be better the third
4:57
way these medications can actually affect your
vision or change your vision is along the same
5:02
lines of changing and drastically decreasing
blood sugar sometimes when you do that it can
5:07
actually change the thickness or the size of
the crystalline lens inside of your eyes and
5:13
I've seen this many times in the clinic a patient
will come in just got put on a new medication for
5:19
their diabetes they have a drastic change or drop
in blood sugar their vision is really blurry and
5:24
we measure their prescription and there's
a drastic change and this is likely due to
5:29
a change in thickness of the crystal lens inside
their eyes and what's unfortunate is that it can
5:34
actually take 3 to 4 months before it actually
stabilizes so in those months the vision can
5:40
still fluctuate and change and sometimes we have
to remake the glasses to try and catch up with
5:45
the prescription change and it could be pretty
frustrating definitely for the patient now I
5:49
actually go into more detail how blood sugar can
actually change and blur your vision in this video
5:55
right here definitely recommend checking it out
because it is all kind of linked and related to
6:00
this if you have any questions let me know in
the comments I hope this helped stay focused
