Nestled in the tissues of your neck is a small unassuming organ that wields enormous power over your body. It's called the thyroid. Like the operations manager in a company, its role is to make sure that the cells in your body are working properly. It does that by using hormones to deliver messages to every single one of them. This high-ranking organ is made up of lobules that each contains smaller cells called follicles, which store the hormones the thyroid sends out into your blood. Two of the most important hormones it produces are thyroxine and triiodothyronine, or T3 and T4. As messengers, the hormone's job is to instruct every cell in the body when to consume oxygen and nutrients. That maintains the body's metabolism, the series of reactions our cells perform to provide us with energy. This hormonal notification from the thyroid gets the heart pumping more efficiently, and makes our cells break down nutrients faster. When you need more energy, the thyroid helps by sending out hormones to increase metabolism. Ultimately, the thyroid allows our cells to use energy, grow and reproduce. The thyroid is controlled by the pituitary gland, a hormonal gland deep in the brain that oversees the thyroid's tasks, making sure it knows when to send out its messengers. The pituitary's role is to sense if hormone levels in the blood are too low or too high, in which case it sends out instructions in the form of the thyroid- stimulating hormone. Even in this tightly controlled system, however, management sometimes slips up. Certain diseases, growths in the thryoid or chemical imbalances in the body can confuse the organ and make it deaf to the pituitary's guiding commands. The first problem this causes is hyperthyroidism, which happens when the organ sends out too many hormones. That means the cells are overloaded with instructions to consume nutrients and oxygen. They become overactive as a result, meaning a person with hyperthyroidism experiences a higher metabolism signaled by a faster heartbeat, constant hunger, and rapid weight loss. They also feel hot, sweaty, anxious, and find it difficult to sleep. The opposite problem is hypothyroidism, which happens when the thyroid sends out too few hormones, meaning the body's cells don't have as many messengers to guide them. In response, cells grow listless and metabolism slows. People with hypothyroidism see symptoms in weight gain, sluggishness, sensitivity to cold, swollen joints and feeling low. Luckily, there are medical treatments that can help trigger the thyroid's activities again, and bring the body back to a steady metabolic rate. For such a little organ, the thyroid wields an awful lot of power. But a healthy thyroid manages our cells so effectively that it can keep us running smoothly without us even noticing it's there.
Organek pir biçûk di stuyê me de cîh girtiye, Lê li ser laşê me xwedî pir hêz e. Dibêjinê Tîroîd. Mîna serkarê kompanîekê, erka wî, kontrolkirina ahenga hucreyên me ye. Bi hormona peyam dişîne hemû hucreyan. Ev organê pir girîng, ji lobûlan pêk tê. Her lobûl jî ji folîkûlan pêk tê. Hormon di folîkûla de tên kom kirin. Hormanên girîng yên ku çêdike, Tyroxine(T3) and TriiodoTyronine(T4) in. Ev hormon e, ji hucreyan re, Peyama wê, kengî O2 û xurek xerckirnê radigihînin. Reaksîyonê di hucreyan de enerjîyê çêdikin metabolîzmayê pêk tînin. Bi bandora hormonê tiroîd, dil leztir lêdixe û hucreyên me leztir dişixûlin. Ku zêdetir enerjî pêwist dibe, hormonên tiroîd metabolīzmayê lezgîntir dikin. Tiroîd enerjî-çêkirin, mezinbûn û zêdebûna hucreyan Kontrol dike. Tiroid jî di bin kontrola petûetêrî de ye. Tiroîd kengî û çiqas hormonan çêke, Petûetêrî birêve dibe. Dema hormonên tiroîd di xwînê de kêm an zêde dibin hîpofîz bi hormona xwe TSH li tiroîd ferman dike û rast dike. Di vê pergala de jî, carinan pirsgirek derdikevin. Hin nexweşî, wek mezinbûna tiroîd, û bê ahengîyên kîmyevî, tiroîd şaş dikin, û tiroîd ji qontrala hîpofîz derdikeve. Pirsgirêka ku yekem derdikeve hipertroîdîzm e. Êv tê wateya ku tiroîd zêde hormon çêdike. Di vê rewşê de hucre leztir dixebitin, û gelek oksîjen ū xurek tê xerc kirin. Mirovên bi hîpertroîdîzm hîperaktîf in, dilê wan leztir lêdixe, zêde birçî dibin û kîloyan didin.. Pir bi xwêdan in, zêde bi hers in û xweş ranazin. Hîpotiroidism tam vajî vê ye; Dema troîd kêm hormon çêdike, derdikeve holê. Metabolîzma hêdî dibe û hucre sist dibin. Mirovên bi hypothyroidisim kîlo distînin, tiral dibin, ji sermayê aciz in, û depresyonê de ne. Baş e ku tedawî heye; bandora troîd rast dike û metabolîzmaya mirov normal dike. Herçend troîd wisa piçûk be jî, ew pir bi hêz e. Tiroîd karê xwe rast bike, beyî heya me jê hebe hûcre bi tenduristî jiyana xwe didomînin.
