In this video I'm going to teach you the difference between hyperthyroid and hypothyroid.
Don't miss this, I'm going to make it super easy for you.
Hello hello my friend, my name is Christina Rafano from nursingschoolofsuccess.com here

So when you think about hyperthyroid and hypothyroid, there is ONE word that I want to come to your
mind.
And that word is.
So think THYROID and METABOLISM.
And what your body's metabolism is, is all of the chemical processes that are happening
inside your body all the time.
So for example, when you eat food, it's the process of metabolism that breaks down that
food into energy.
So here's what this means for hyperthyroid and hypothyroid: HYPERthyroid means an INCREASE
in the body's metabolism, so the body will break down all of that food into energy super
fast.
Now, HYPOthyroid means a DECREASE in metabolism, so it will take a lot longer to break down
that food into energy.
So the thyroid is ALL about the body's metabolism, so anytime you see or hear the word "thyroid,"
I want you to think METABOLISM.
Both hyperthyroid and hypothyroid have to do with 2 hormones: T4 and T3.
Now these have big fancy names which are thyroxine and tri- iodo- thyRonine.
I just wanted to mention that here just in case you come across those names on a nursing
school exam, so now you'll know what they are.
They're just the fancy pants names for T4 and T3 which are those thyroid hormones.
Now I'm going to run through some basic pathophysiology here with you about how hyperthyroid and hypothyroid
work in the body.
If you want a step-by-step guide for how this works, or any other endocrine disorder you're
learning about in nursing school, you'll definitely want to jump into the NursingSOS Membership
Community where we have a full endocrine course that will walk you through, step-by-step,
all the pathophysiology, signs and symptoms, nursing assessment and nursing interventions
for the endocrine disorders you're learning about.
So that link is down below for you to check that out.
So what's going on during hyperthyroid and hypothyroid?
During hyperthyroid, the thyroid gland is going to inappropriately make more T4 and
T3.
Even though there's already enough T4 and T3 in the body, the thyroid gland is still
going to make more and more of it.
The biggest cause of this is Graves' Disease.
Graves' disease is an autoimmune disorder where the body's own immune system is lying
to the thyroid gland.
The immune system tells the thyroid gland that the body needs more thyroid hormone,
even when it doesn't.
So the thyroid gland then goes and makes more T4 and T3, even when the body doesn't really
need it.
So that's hyperthyroid.
The thyroid gland is making too much T4 and T3.
So there is too much of those thyroid hormones in the body, which leads to an increase in
the body's metabolism.
On the flip side, during hypothyroid the thyroid gland can't produce T4 or T3.
So the brain keeps telling it to make more T4 and T3 but the thyroid gland just can't.
The 2 biggest causes of hypothyroid is a lack of iodine, which is necessary to make T4 and
T3, so without that iodine the thyroid gland just can't produce those thyroid hormones.
And hypothyroid can also be caused by Hashimoto's thyroiditis, where the body's own immune system
attacks the thyroid gland so it can't function.
In both of these cases, the thyroid gland cannot produce those thyroid hormones, that
T4 and T3.
So there is less thyroid hormone in the body, which causes a decrease in metabolism.

hypothyroid better for your nursing school exam.
