00:00
Okay.
00:01
Now let's
look at the next part of your results.
00:04
So look at this.
00:04
Some of these may be present.
00:06
So there might be some glucose, some
your virgin, some blood, some protein.
00:11
You've got the whole list there
and we've got a cheat sheet for you
at the end that puts this all together.
00:17
But some of these may be present
in your urine, and it's okay.
00:22
We're not worried about it.
00:23
Let's look at glucose in your urine.
00:25
Normal levels of glucose
would be less than or equal to 130.
00:30
So glucose is normally filtered
by the glomerulus.
00:33
What is the glomerulus?
Yeah, it's that tangle of capillaries
that's right inside of Bowman's capsule
and it's all connected up to the tubules
and your kidneys.
00:43
So glucose
is normally filtered by the glomerulus,
but almost completely reabsorbed
in the proximal tubule.
00:51
So when we say that,
that's great to have the definition,
but I want you to picture it.
00:55
So you have that picture in your mind
of what a Marius looks like.
00:58
It's a tangle of capillaries.
01:00
Inside of Bowman's capsule. Right.
01:03
And that is connected to the tubules.
01:06
So when it says that glucose is almost
completely reabsorb in the tubule,
that means it comes out of the filtrate,
back into the body circulation.
01:15
It should not be leaving the body
in the urine.
01:19
So it's okay
to have less than or equal to 130.
01:23
But if you've got more of that,
we've got a problem.
01:27
Now glycol Surya means you've got glucose,
usually around 180 to 200.
01:33
Normal is less than 130.
01:35
Once you hit 180, you get a diagnosis.
01:38
So there's that word again, urea.
01:40
That means urine.
01:42
Whatever comes in front of
that means what's in the urine.
01:45
Oh, glucose.
01:46
So that's why glucose.
01:47
Urea means a too high
of a level of glucose in your urine.
01:52
That means the filtered load of glucose
exceeds
your kidneys ability to reabsorb it. Huh.
01:59
I wonder who would have too much glucose
in their blood to the point
where the kidneys couldn't reabsorb it?
Yeah, you're right.
02:09
Let's look at the possible causes.
02:10
Ding, ding, ding, ding, ding.
02:11
Number one, diabetes mellitus.
02:14
Or if you prefer mellitus,
however you want to say it,
that's who's going to have too much blood
sugar.
02:22
Right.
02:22
People with diabetes.
02:24
That is the that's the risk.
02:26
And the cause of diabetes
is an elevated blood glucose level.
02:30
So when that blood is heading on
into the kidney,
it is over saturated with glucose.
02:36
It is more than the kidneys
can or should reabsorb,
which is why it tries
to get rid of some of it in the urine.
02:45
So if someone has glucose here,
we would expect they have diabetes.
02:49
Now, Cushing's syndrome,
we're back to that endocrine system.
02:53
If a patient has Cushing's syndrome,
this happens with someone who's received
high dose corticosteroids.
02:59
So not somebody who
usually has an inhaler.
03:02
Talking about somebody who's been on
pretty high dose glucocorticoid therapy,
either taking it by a pill or I.V.,
they tend to have more systemic results.
03:14
But remember, they end up with those weird
side effects like moon face, facial
hair, mood swings,
all kinds of weird stuff.
03:20
But Cushing's syndrome
looks like Cushing's disease
because they have excess glucocorticoid.
03:29
So remember, glucocorticoids
come from my adrenal glands, right?
They come from the adrenal cortex.
03:36
But when I give them to you
as a medication, then I can cause
Cushing's syndrome.
03:41
It's like your adrenal gland
said, Hey, party.
03:44
And it just starts shooting out
way too much.
03:47
Well, in Cushing syndrome,
we did that to you.
03:51
You're welcome. No charge.
03:53
Cushing syndrome happens
when a patient receives
excess high doses of glucocorticoids
because we're trying to suppress
inflammation somewhere in their body
that messes with their protein,
fat and sugar metabolism.
04:06
So that's why you end up with excess
levels of glucose in your urine.
04:12
If someone's on
glucocorticoid therapy,
their blood sugar is usually elevated.
04:17
If you've got a diabetic
on glucocorticoid therapy,
their blood sugars can go crazy.
04:23
Now, we also have issues with liver
and pancreatic diseases
and something we call Fanconi Syndrome.
04:30
Now you can follow
that away is fun trivia.
04:33
The most important point
I want you to take away
are diabetes, Cushing's and then your
liver and pancreatic diseases.
04:42
Then Cooney's we put on there,
but we're not even going to delve into it.
04:45
It's just something interesting
for you to know.
04:48
But number one, take away diabetes.
04:50
Second one, Cushing's syndrome.
04:53
And make sure you got to know that that's
caused by glucocorticoid medications.
04:58
And then liver and pancreatic disease,
because those are key players
with endocrine and hormone.
