Lɛ wi lan bɔt di smɔl hiro we de na wi bren: di Posterior Pituitary Gland!

Wi bɔdi tan lɛk mashin we rili wɔndaful ɛn we kɔmpleks, nɔto so? Wi ɔl no se na wi bren de kɔntrol ɔltin na dis mashin. Bɔt yu no se insay yu bren, wan gland de we smɔl lɛk smɔl bon, we de pul rili impɔtant ɔmon dɛn we de kɔntrol di wata we de na yu bɔdi, we de mek di uterus kɔntrakt we yu de bɔn pikin, ɛn mek da fayn fayn padi biznɛs de bitwin mama ɛn pikin? Na dat wi go tok abaut tide. Wi kɔl dis di Pituitary Gland. Tide, wi go tɔk ditayli bɔt wan spɛshal pat pan am, we na di Posterior Pituitary.

Fɔs, lɛ wi si, wetin na di pituitary gland?

Imajin se yu bɔdi na big kɔmni. Dɔn di CEO fɔ da kɔmni de na di pat pan di bren we dɛn kɔl di haypothalamus. Dɔŋ dis CEO na wan jenɛral manija. Dat na di pituitary gland. dis manija rili impɔtant, bikɔs i de kɔntrol di wok we bɔku ɔda gland dɛn de du na di bɔdi.

Dis pituitary gland de ɔnda yu bren, biɛn yu nos, na say we rili sef. I sheb to tu pat. Lɛk di frɔnt risepshɔn dɛsk na ɔfis ɛn bak ɔfis.

1. Anterior Pituitary: Dis na di pat we big pas ɔl ɛn we bizi pas ɔl. I de mek ɛn pul bɔku ɔmon dɛn we gɛt fɔ du wit di we aw di bɔdi de gro, di we aw di tayroyd de wok, ɛn aw i de du mami ɛn dadi biznɛs.

2. Posterior Pituitary: Dis na wi protagonist. i sכm pas di antεriכr pituitary. I nɔ de mek ɔmon, bɔt i de kip tu spɛshal ɔmon dɛn we di haypothalamus de mek ɛn sɛn, ɛn i de pul dɛn insay di blɔd we nid de.

di sistεm we inklud כl di gland dεm we de mek כmon dεm, inklud di pituitary gland, dεn kכl am di εndokrin sistεm . dis na di nεtwכk we de chenj kεmikכl mεsej dεm na di bכdi.

So wetin na dɛn tu spɛshal ɔmon dɛn de we di Posterior Pituitary de pul?

As wi bin dɔn tɔk, di Posterior Pituitary tan lɛk westɛm. Tu "guds" we rili valyu de we dɛn dɔn kip ya. Dɛn na tu ɔmon dɛn. Na di Hypothalamus de mek dɛn tu tin ya. we mɛsej kכmכt frכm de tru di nεv dεm, di Posterior Pituitary de rilis dεn כmon dεm ya insay di bכdi.

Na dis na simpul ɛksplen bɔt dɛn tu ɔmon ya ɛn aw dɛn de wok.

Imajin wan tɛm we yu de swet bɔku bɔku wan ɛn yu tɔsti. Da tɛm de, yu blɔd kin tik smɔl. di haypothalamus na di bren de no dis εn i de sεnd signal to di Posterior Pituitary, we de se, "Okay, naw put sכm ADH insay di bכdi." Dɔn ADH go tɛl di kidni dɛm se, "Yuz wata smɔl, nɔ mek tumɔs urine." Na da tɛm de di urine we yu de pas de go dɔŋ, ɛn in kɔlɔ de dak. We yu gɛt wɛl wata, di ɔpɔsitet kin apin. di ADH lεvεl dεm de dכn, εn di wata we pasmak de kכmכt as urine. Yu nɔ tink se na wɔndaful kɔntrol?

Wetin na di sik dɛm wae kin gɛt fɔ du wit di Posterior Pituitary?

Jɛnɛral wan, big big sik dɛn we gɛt fɔ du wit dis gland nɔ kin bɔku. כltu, sכmtεm, sכm prכblεm dεm kin kam bikoz fכ di sekreshכn we pasmak (haypa sekreshכn) כ we nכ de kכl dεm (hyposecretion) fכ dεn ADH εn כksitosin כmon dεm ya.

1. Hyposekreshɔn fɔ ADH

if di bכdi in prodakshכn כ rilis fכ di ADH כmon dכn rεdכks, di kidni dεm de lכs di signal fכ riabsכp di wata we dεn nid. Dis min se klos to ɔl di wata we yu de drink kin dɔn na yu urine. Dɛn kɔl dis sik Sɛntral Dayabitis Insipidus (CDI) .

Dis kכndyushכn kin kכz bay we di haypothalamus כ pituitary gland dεm dεn dכn pwεl. Sɔntɛnde, dɛn nɔ kin ebul fɔ fɛn ɛni rizin.

Di men sayn dɛn we de sho se i gɛt dis sik:

• Yu kin pis pasmak (Polyuria): Yu kin pas sɔm lita urine ɛvride. Sɔntɛm yu go nid fɔ go na di was rum bɔku tɛm.
• Tɔsti pasmak (Polydipsia): I nɔ mata ɔmɔs wata yu drink, yu kin fil lɛk se yu nɔ de gɛt inof. As yu bɔdi de lɔs wata, yu bren de sho yu sayn fɔ kɔntinyu fɔ drink wata.
• Dehydration: If yu nɔ drink bɛtɛ wata, yu kin lɔs wata na yu bɔdi.
• Taya: If yu fɔ grap bɔku tɛm na nɛt fɔ pis, dat kin mek yu nɔ slip fayn ɛn mek yu fil taya ɔl di de.

2. If di ADH ɔmon go ɔp (Hypersecretion of ADH) .

Dis na di ɔpɔzit to di wan we bin de bifo. If tumɔs ADH ɔmon de na di bɔdi, di kidni dɛn kin tek tumɔs wata bak insay di bɔdi. Dis kin mek bɔku urine kɔmɔt na di bɔdi. Dis kin mek wata gɛda na di bɔdi ɛn di sɔdiɔm (sɔl) lɛvɛl na di blɔd kin smɔl we denja. Dɛn kɔl dis sik SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion) .

Tin dɛn we kin mek dis apin:

• Sɔm mɛrɛsin (e.g., sɔm mɛrɛsin fɔ dayabitis ɛn ɛpilepshi).
• Afta dɛn dɔn du ɔpreshɔn ɔnda anestezi.
• Kɔndishɔn lɛk wae yu gɛt injury na yu bren, yu gɛt infɛkshɔn, ɔ yu gɛt strok.

Di men sayn dɛm (bɔku tɛm dɛn kin kam bikɔs di sodium nɔ bɔku na di blɔd):

• Nɔs ɛn vɔmit.
• Ed de at.
• Fɔ fil lɛk se yu de lɔs yu balans ɛn yu de kam fɔ fɔdɔm.
• di chenj dεm na di mεntal lεk fכ mεmכri εn agitεshכn.

3. Prɔblɛm dɛn we gɛt fɔ du wit di ɔmon we dɛn kɔl Oxytocin

Infakt, sik dɛm wae kin kam wae dis ɔmon, ɔksitɔsin, nɔr ɔr bɔrku, nɔr kin bɔrku. Na wan kɔndishɔn we nɔ kin apin so ɔltɛm.

• If ɔksitɔsin nɔ bɔku: di uterus nɔ kin kɔntrakt fayn we i de bɔn, ɛn di milk nɔ kin kam insay afta dɛn bɔn di pikin.
• If ɔksitɔsin go bɔku: Dis bak nɔ kin apin so ɔltɛm. i kin mek di uterin mכsul dεm gro tu mכch, we kin mek i at fכ di pikin fכ ol.

Aw yu go no if prɔblɛm de wit di Posterior Pituitary?

If yu gɛt de sik wae wi bin dɔn tɔk bɔt, yu dɔktɔ go aks yu fɔs bɔt yu sik. Dɔn, dɛn kin du sɔm tɛst dɛn fɔ no di kɔrɛkt pikchɔ bɔt di ɔmon lɛvɛl we yu gɛt.

• Blɔd Tɛst: Dɛn kin mɛzhɔ tin dɛn lɛk di ADH ɔmon lɛvɛl ɛn di blɔd sodium lɛvɛl.
• Yurin Test: Yu kin si aw yu urine tik ɔ tan.
• MRI skan: Dis kin ɛp fɔ chɛk fɔ ɛni tumbu ɔ damej pan di pituitary gland ɔ haypothalamus.

Yu dɔktɔ go disayd fɔ tritmɛnt bay di rizɔlt fɔ dɛn tɛst ya.

Ustɛm a fɔ go to dɔktɔ?

Bɔrku pan de kɔndishɔn wae wi dɔn tɔk bɔt nɔr kin bɔrku. Bɔt if yu notis se yu bɔdi dɔn chenj, i go fayn fɔ lɛ yu nɔ pe atɛnshɔn to am.

Na mɔtalman, if yu gɛt wan ɔr mɔr pan dɛn sik ya, nɔr west tɛm ɛn go to yu dɔktɔ.

• If yu tɔsti we yu nɔ go ebul fɔ imajin ɛn yu de pis pasmak ɔltɛm .
• If yu gɛt nɔys, vɔmit, ed we de at, ɛn fil se yu nɔ balans fɔ natin.
• If yu fil wantɛm wantɛm se yu mɛmori dɔn kɔnfyus ɛn yu nɔ ebul fɔ pe atɛnshɔn .

Sɔntɛnde lɛk dis, we yu go to dɔktɔ ɛn du sɔm simpul tɛst dɛn, dat kin ɛp yu fɔ no if prɔblɛm de ɔ nɔ gɛt prɔblɛm. So nɔ fred fɔ go to dɔktɔ.
