00:17
Like the operations manager in a company,

Bi hormona peyam dişîne hemû hucreyan.
Ev organê pir girîng, ji lobûlan pêk tê.
00:29
This high-ranking organ is made up of lobules
6
29523
3371
00:32
that each contains smaller cells called follicles,
7
32894
3285
Her lobûl jî ji folîkûlan pêk tê.
00:36
which store the hormones the thyroid sends out into your blood.

Hormon di folîkûla de tên kom kirin.
00:39
Two of the most important hormones it produces
9
39584
2238
Hormanên girîng yên ku çêdike,
00:41
are thyroxine and triiodothyronine, or T3 and T4.
10
41822
6787
Tyroxine(T3) and TriiodoTyronine(T4) in.
00:48
As messengers, the hormone's job
11
48609
2118
Ev hormon e, ji hucreyan re,
00:50
is to instruct every cell in the body when to consume oxygen and nutrients.
12
50727
4848
Peyama wê, kengî O2 û xurek xerckirnê radigihînin.
00:55
That maintains the body's metabolism,
13
55575
2222
Reaksîyonê di hucreyan de enerjîyê çêdikin
00:57
the series of reactions our cells perform to provide us with energy.
14

metabolîzmayê pêk tînin.
01:02
This hormonal notification from the thyroid
15
62936
2443
Bi bandora hormonê tiroîd,
01:05
gets the heart pumping more efficiently,
16
65379
2636
dil leztir lêdixe û
01:08
and makes our cells break down nutrients faster.
17
68015
3283
hucreyên me leztir dişixûlin.
Ku zêdetir enerjî pêwist dibe,
01:11
When you need more energy,
18
71298
1510
01:12
the thyroid helps by sending out hormones to increase metabolism.
19
72808
4462
hormonên tiroîd metabolīzmayê lezgîntir dikin.
01:17
Ultimately, the thyroid allows our cells to use energy, grow and reproduce.
20
77270

Tiroîd enerjî-çêkirin, mezinbûn û zêdebûna hucreyan Kontrol dike.
01:24
The thyroid is controlled by the pituitary gland,
21
84344
3365
Tiroid jî di bin kontrola petûetêrî de ye.
01:27
a hormonal gland deep in the brain that oversees the thyroid's tasks,
22
87709
4632
Tiroîd kengî û çiqas hormonan çêke,
01:32
making sure it knows when to send out its messengers.
23
92341
3475
Petûetêrî birêve dibe.
01:35
The pituitary's role is to sense if hormone levels in the blood
24
95816
3434
Dema hormonên tiroîd di xwînê de
01:39
are too low or too high,
25
99250
1557
kêm an zêde dibin
01:40
in which case it sends out instructions
26
100807
2427
hîpofîz bi hormona xwe TSH
01:43
in the form of the thyroid- stimulating hormone.
27
103234
3417
li tiroîd ferman dike û rast dike.
01:46
Even in this tightly controlled system, however,
28
106651
2369
Di vê pergala de jî,
01:49
management sometimes slips up.
29
109020
2924
carinan pirsgirek derdikevin.
01:51
Certain diseases,
30
111944
1286
Hin nexweşî,
01:53
growths in the thryoid
31
113230
1350
wek mezinbûna tiroîd,
01:54
or chemical imbalances in the body can confuse the organ
32
114580
3762
û bê ahengîyên kîmyevî, tiroîd şaş dikin,
01:58
and make it deaf to the pituitary's guiding commands.
33
118342
3699
û tiroîd ji qontrala hîpofîz derdikeve.
02:02
The first problem this causes is hyperthyroidism,
34
122041
3130
Pirsgirêka ku yekem derdikeve hipertroîdîzm e.
02:05
which happens when the organ sends out too many hormones.
35
125171
4066
Êv tê wateya ku tiroîd zêde hormon çêdike.
02:09
That means the cells are overloaded with instructions
36
129237
2722
Di vê rewşê de hucre leztir dixebitin,
02:11
to consume nutrients and oxygen.
37
131959
2706
û gelek oksîjen ū xurek tê xerc kirin.
02:14
They become overactive as a result,
38
134665
2563
Mirovên bi hîpertroîdîzm hîperaktîf in,
02:17
meaning a person with hyperthyroidism experiences a higher metabolism
39
137228
4667
dilê wan leztir lêdixe, zêde birçî dibin
02:21
signaled by a faster heartbeat, constant hunger, and rapid weight loss.
40

û kîloyan didin..
02:27
They also feel hot, sweaty, anxious, and find it difficult to sleep.
41
147131
4910
Pir bi xwêdan in, zêde bi hers in û xweş ranazin.
02:32
The opposite problem is hypothyroidism,
42
152041
3154
Hîpotiroidism tam vajî vê ye;
02:35
which happens when the thyroid sends out too few hormones,
43
155195
3668
Dema troîd kêm hormon çêdike,
02:38
meaning the body's cells don't have as many messengers to guide them.
44
158863
3984
derdikeve holê.
02:42
In response, cells grow listless and metabolism slows.
45
162847
4432
Metabolîzma hêdî dibe û hucre sist dibin.
02:47
People with hypothyroidism see symptoms in weight gain,
46
167279
3763
Mirovên bi hypothyroidisim kîlo distînin,
02:51
sluggishness, sensitivity to cold, swollen joints and feeling low.
47
171042

tiral dibin, ji sermayê aciz in, û depresyonê de ne.
Baş e ku tedawî heye;
02:57
Luckily, there are medical treatments
48
177341
1927
02:59
that can help trigger the thyroid's activities again,
49
179268
2924
bandora troîd rast dike û
03:02
and bring the body back to a steady metabolic rate.
50
182192
3305
metabolîzmaya mirov normal dike.
03:05
For such a little organ, the thyroid wields an awful lot of power.
51
185497
4814
Herçend troîd wisa piçûk be jî, ew pir bi hêz e.
03:10
But a healthy thyroid manages our cells so effectively
52
190311
3505
Tiroîd karê xwe rast bike, beyî heya me jê hebe
03:13
that it can keep us running smoothly without us even noticing it's there.
53
193816
4887
hûcre bi tenduristî jiyana xwe didomînin.
