Akohia te Cortisol: Te Mahi me ngā Pānga Hauora

"E te tākuta, kua roa ahau e pāngia ana e te ahotea nui nā te pēhanga o te mahi. Nō nā tata nei, kua nui haere taku puku me taku mata, ā, kua angiangi haere ōku ringa me ōku waewae. E tino ngenge ana ahau, ā, kāore e taea e au te moe i te pō." I haere mai a Ruwan, 35 tau te pakeke, ki tā mātou whare hauora me te manukanuka nui. I whakaaro ia kei te pāngia ia e te mate e kiia nei ko te "Adrenal Fatigue."

Engari he rerekē te take hauora tūturu. Ko te homoni matua e whakahaere ana i te ahotea i roto i tō tātou tinana ko te homoni cortisol. Kia mārama noa tātou ki te papamuri hauora tūturu kei muri i ngā tohumate o Ruwan me te pānga o te homoni cortisol ki te mahi a tō tātou tinana.

He homoni steroid te Cortisol i roto i te rōpū o ngā glucocorticoids. Ka hangaia, ka tukuna hoki e ngā repe adrenal, kei runga ake i ō tātou whatukuhu. He rite te mahi a te Cortisol ki te pūnaha whakaoho taiao o te tinana. Ka āwhina hoki ia ki te whakahaere i ngā tukanga nui maha e puta tonu ana i roto i te tinana. Ka whakahaerehia tōna whakaputanga e tētahi whatunga whakawhitiwhiti kōrero matatini i waenga i te roro (ina koa ko te hypothalamus me te repe pituitary) me ngā repe adrenal.

Ngā mahi rerekē a te cortisol: kei tua atu i te urupare ahotea

Ahakoa he mahi nui te whakahaere i te ahotea, ka pā te cortisol ki te nuinga o ngā pūnaha okana o te tinana. Anei ētahi o ana mahi matua:

#### 1. Te whakahaere i te urupare a te tinana ki te ahotea

Ina puta he ahotea poto, he ahotea roa rānei, ka tukuna wawetia e te tinana ngā homoni pēnei i te adrenaline hei urupare (arā, "whawhai, rere rānei"). Ka uru atu te cortisol, hei āwhina i te tinana kia mataara, kia whakarato hoki i te pūngao e tika ana. Mā te tuku i te hukahuka - he huka - mai i te ate. Koinei te mea e whakarato ana i te pūngao e hiahiatia ana hei whakatau i te ahotea.

#### 2. Te pākia o te tinana me te whakahaere i te huka toto

He homoni nui te cortisol mō te pākia o te tinana - te huarahi e whakamahia ai e te tinana te pūngao - ā, ka āwhina anō hoki ki te whakahaere i ngā taumata huka toto mā te whakahaere i te mahi a te insulin me te glucagon, te whakahaere i te whakamahinga a ngā pūtau ngako, uaua me te ate i te hukahuka.

#### 3. Te Whakahaere i te Mumura

I roto i te wā poto, ka mahi te cortisol hei ārai-mumura tūturu, hei āwhina i te whakaiti i te mumura i roto i te tinana. Heoi, ki te teitei ngā taumata cortisol mō te wā roa, ka pā te pānga rerekē. Arā, ka taea e ia te whakanui ake i te mumura me te ngoikore i te pūnaha ārai mate i roto i te wā.

#### 4. Te whakahaere i te toto totoka

Kua whakaaturia hoki i roto i te pūtaiao hauora te āwhina o te cortisol ki te whakahaere i te toto toto. Ina piki, ina heke rānei ngā taumata cortisol, he hononga tika kei waenganui i te pikinga me te hekenga o te toto toto.

#### 5. Te Pānga ki te Rhythm Circadian

Ka piki, ka heke hoki ngā taumata cortisol puta noa i te rā. Ka eke ki tōna taumata teitei i mua tata tonu i te oho ake i te ata, ā, ka heke ki ō rātou taumata iti rawa i te wā moe. He mea nui tēnei manawataki circadian mō te moe pai me te oho ake i te wā hou.

He aha mēnā he nui rawa ngā taumata cortisol? (Hypercortisolism)

Kāore te nui o te cortisol i te pai mō tō hauora i ngā wā katoa (he āhuatanga e kiia nei ko te Cushing's Syndrome). Kāore i te maha ngā wā ka puta mai i te ahotea o ia rā anake. Ko ngā tino take ko:

• Ngā Rongoā: Te whakamahinga roa o ngā horopeta nui o ngā rongoā corticosteroid (hei tauira, prednisolone).
• Ngā Puku: Ka taea e ngā puku i roto i te repe pituitary, i ngā repe adrenal rānei te whakaputa nui i te cortisol, i ngā homoni rānei e whakaoho ana i tōna whakaputanga (ina koa ko te ACTH - Adrenocorticotropic Hormone).

#### Ngā tohu noa o te taumata cortisol teitei:

Ko te hunga kua roa nei e nui ana te cortisol ka pāngia pea e ēnei tohu:

• Te pikinga nui o te taumaha, inā koa ki te mata ("mata marama") me te puku. Tērā pea ka angiangi ngā peka me ngā waewae.
• Ngā putunga ngako i muri i ngā pakihiwi ("Buffalo pump").
• He whānui, he papura ngā tohu totoro, inā koa ki te puku.
• Te ngoikore o te uaua.
• Te pikinga o te huka toto (ka arahi pea tēnei ki te mate huka momo 2).
• Te toto toto tiketike (hypertension).
• Ngāwari te marō.
• Ngā wheua pakarukaru (Osteoporosis).
• I roto i ngā wāhine, ka tupu ngā pūtake makawe pērā i ngā tāne (hirsutism) ka puta rānei te paheketanga koretake.

He aha mēnā ka tino iti rawa ngā taumata cortisol? (Te ngoikore o te adrenal)

Ko te koretake o te adrenal he taumata cortisol tino iti. Ko te tikanga tēnei kāore e nui te cortisol e whakaputaina ana e ngā repe adrenal. Ko ngā take matua mō tēnei ko:

• Te ngoikore tuatahi o te repe adrenal (te mate a Addison): Ko te tikanga ka puta mai tēnei i tētahi mate pūnaha ārai mate. Ko te tikanga ka whakaekea e te pūnaha ārai mate o te tinana ngā repe adrenal. Ka taea hoki e te mate urutā, e ētahi atu kino rānei te take.
• Te koretake o te adrenal/te ngoikore tuarua: Ko ngā raruraru o te repe pituitary (pēnei i ngā pukupuku, te ngoikore o te mahi) ka hua ake te hekenga o te hanga o te homoni ACTH, e tohu ana i te hanga o te cortisol. Ka puta anō hoki i muri i te whakamutu ohorere i te rongoā corticosteroid mō te wā roa.

#### Ngā tohu o te iti o te taumata cortisol:

• Te ngenge nui tonu me te ngoikore o te ngākau.
• Te ngaronga taumaha mō te kore take.
• Kāore he reka o te kai.
• Te toto toto iti (te toto toto iti) (tērā pea ka hemo te ngākau ina tū).
• Whakapairuaki, ruaki, mamae rānei te puku.
• Te mamae o te uaua, o te hononga rānei.
• Te parauri o te kiri (Hyperpigmentation) - inā koa i te mate a Addison.

🚨 Ngā tohu o te raruraru adrenal e hiahia ana kia aro wawe ki te hauora

Ka puta he mate pāwera nui ki te roro ina heke tere rawa te homoni cortisol ki raro iho i ngā taumata noa o te tinana. Me rapu awhina hauora tonu koe mēnā ka pāngia koe e ēnei tohu:

• Mamae ohorere, mamae nui: Mamae ohorere, mamae nui ki te tuara o raro, te puku, ngā waewae rānei.
• Te ruaki nui me te korere: Te ruaki tonu me te korere e whakararuraru ana i te tinana.
• Te ohorere: He hekenga o te toto totoka e ngaro ai te māramatanga, e hemo ai rānei.
• Te hiamoe me te pōhēhē: Te hiamoe, te pōhēhē rānei e puta mai ana me te kirika nui.

🛠️ Ngā Mahi hei Pupuri i te Taurite o te Hormone Cortisol

• Hipanga Tuatahi: Ki te whakapae koe he raruraru homoni cortisol tōu, me toro atu ki te tākuta endocrinologist tonu, ka whakamātauria he homoni (huware, toto, whakamātautau mimi 24-hāora rānei).
• Hipanga Tuarua: Kaua e tango i ngā rongoā steroids pērā i te Prednisolone, Dexamethasone rānei, e hokona ana i ngā whare rongoā me te kore he whakahaunga a te tākuta.
• Hipanga Tuatoru: Mena kua tāpaetia kei a koe tētahi āhuatanga pēnei i te mate a Cushing, te ngoikore rānei o te adrenal, tangohia te rongoā whakakapinga homoni i tohua e tō tākuta kia rite ki ngā tohutohu.
• Hipanga Tuawhā: Whakaritea kia haere koe ki te moenga me te ara ake i te wā kotahi i ia rā hei pupuri i te manawataki circadian o tō tinana.
• Hipanga Tuarima: Whakaharatauhia te whakaaroaro, te manawa hōhonu, me te whakakori tinana hei whakaiti i te ahotea.
