Oluusi owulira nga waliwo ekikyamu ku mubiri gwo, ng’obusimu bwo buweddewo? Mpozzi nga kiva ku nseke entono mu bwongo bwo. Ensigo eno bw’ekola ekisusse, esobola okukosa emirimu mingi emikulu mu mubiri gwo, gamba ng’okukula, okukyusakyusa mu mubiri, n’okuzaala. Leero twogera ku nseke ezikola ennyo oba hyperpituitarism.
Ensigo ya Pituitary Gland kye ki?
Mu ngeri ennyangu, enseke y’omubiri (pituitary gland) eringa ekifo ekikulu ekifuga emirimu gy’omubiri gwaffe. Ye nnywanto eringa entangawuuzi esangibwa wansi w’obwongo bwaffe. Ye mutwe gw’enkola yaffe ey’omubiri (endocrine system). Eno y'ensonga lwaki oluusi kiyitibwa "master gland". Kifuga enkola y’endwadde endala enkulu nga thyroid gland, adrenal gland, ne gonadal glands.
Lowooza ku thermostat mu nnyumba yaffe. Bulijjo ekebera ebbugumu mu nnyumba n’eweereza obubaka ku hhuta ne cooler okugikuuma ku mutindo gwe gumu, nedda? Ensigo y’omubiri (pituitary gland) nayo ekola mu ngeri y’emu. Bulijjo erondoola enkola y’omubiri gwaffe era n’eweereza obubonero eri ebitundu by’omubiri n’endwadde eziraga omulimu gwe tulina okukola, ddi, n’obungi. Obubonero buno bwe tuyita obusimu .
Ensigo y’omubiri (pituitary gland) eyungibwa ku kitundu ky’obwongo bwaffe ekiyitibwa hypothalamus. Obwongo bugamba enseke oba okufulumya obusimu obumu obusinga oba obutono.
Busimu ki obukulu obukolebwa enseke z’omubiri (pituitary gland)?
Ensigo ya pituitary erimu ebitundu ebikulu bisatu. Buli kitundu kikola obusimu obw’enjawulo. Ka tulabe kiki kye bali ne kiki ekibatuukako.
| Ekitundu ky’endwadde | Obusimu obuyitibwa hormone | Omulimu omukulu |
|---|---|---|
| Ekitundu eky’omu maaso (Ebitundu nga 80% ku nseke) | Obusimu obuyitibwa adrenocorticotropic hormone (ACTH) . | Kisitula endwadde z’ekibumba naddala okukola obusimu obuyitibwa ‘stress hormone’ obuyitibwa cortisol obutereeza puleesa n’abaserikale b’omubiri. |
| Obusimu bw’okukula (GH) . | Kifuga enkula y’omubiri (naddala mu baana), enkyukakyuka mu mubiri, n’obutonde bw’omubiri (amasavu, ebinywa). | |
| Obusimu obusitula thyroid (TSH) . | Asitula enseke z’omubiri (thyroid gland) n’ayamba okukola obusimu obuyitibwa thyroid hormones, obufuga amaanyi g’omubiri. | |
| Ebirungo ebiyitibwa Gonadotropins (LH ne FSH) . | Enkwaso n’ensigo bisikirizibwa okukola obusimu bw’okwegatta obwetaagisa okuzaala. | |
| Ekirungo kya Prolactin | Ayamba okukola amata g’amabeere oluvannyuma lw’okuzaala. | |
| Ekitundu eky’omu makkati | Obusimu obusitula obutoffaali obukola omubiri (melanocyte-stimulating hormone). | Akosa langi y’olususu. |
| Ekitundu eky’emabega | Obusimu obuziyiza okufulumya omusulo (ADH) . | Afuga bbalansi y’amazzi n’amasannyalaze g’omubiri. |
| Ekirungo kya oxytocin | Afuga okukonziba kwa nnabaana n’okufulumya amata g’amabeere ng’azaala. |
Endwadde ki ezibeerawo ng’endwadde z’omu lubuto (pituitary gland) zikola ekisusse?
Ensigo y’omubiri (pituitary gland) bw’ekola ennyo, kwe kugamba, bw’ekola obusimu obuyitiridde, embeera ez’enjawulo ez’obujjanjabi ziyinza okubaawo. Ekisinga okuvaako kino kizimba ekitali kya kookolo (benign) ekikula mu nseke. Kino kiyitibwa obulwadde bwa pituitary adenoma .
Zino zezimu ku ndwadde enkulu eziyinza okuva ku kino:
- Obulwadde bwa Cushing: Singa endwadde z’omu lubuto (pituitary gland) zifulumya ACTH mungi, endwadde z’ekibumba zikola ‘cortisol’ mungi ekiyinza okutaataaganya enkola y’omubiri n’abaserikale b’omubiri.
- Acromegaly: Embeera ebeerawo ng’obusimu obukula mu mubiri (GH) buyitiridde. Kino kireetera amagumba n’ebitundu by’omubiri okukula mu ngeri etaali ya bulijjo.
- Hyperthyroidism: Singa ekizimba mu pituitary kivaamu TSH nnyingi (kino tekitera kubaawo), endwadde ya thyroid ekola ekisusse. Kino kiyinza okuvaako ebintu nga okweyongera kw’omubiri, omutima okukuba amangu, n’okweraliikirira.
- Prolactinoma: Ekizimba mu nseke ekivaako okufulumya obusimu obuyitibwa prolactin obuyitiridde. Kino kiyinza okukosa enkola y’okuzaala mu bakyala n’abasajja.
Olw’okuba embeera zino ziyinza okuba ez’amaanyi, kikulu nnyo okulaba omusawo mu bwangu bw’oba olina obubonero buno.
Bubonero ki obulaga embeera zino?
Obubonero obukwatagana ne buli mbeera bwa njawulo. Ka tulabe bino bye biruwa. Laba oba naawe olina obubonero buno.
| Kakwakkulizo | Obubonero Obuyinza Okubaawo |
|---|---|
| Obulwadde bwa Cushing |
|
| Obulwadde bwa acromegaly |
*Kino bwe kituuka ku baana, kiyitibwa 'gigantism.' Ziyinza okukula obuwanvu mu ngeri etaali ya bulijjo. |
| Obulwadde bwa thyroid obusukkiridde |
|
| Obulwadde bwa Prolactinoma | Ku bakyala:
Ku basajja:
*Ku njuyi zombi: Okulumwa omutwe n’okulaba obuzibu biyinza okubaawo (olw’ekizimba okugaziwa n’okunyigiriza ku busimu bw’amaaso). |
Obulwadde bwa hyperpituitarism mu baana
Embeera eno tetera kubaawo nnyo mu baana. Bwe kibaawo, kitera okuva ku kizimba ekitono ekitali kya kookolo ekiyitibwa pituitary microadenoma. Embeera esinga okulabibwa mu baana ye prolactinoma.
- Ku bawala: Okulwawo okutuuka mu myaka gy’obuvubuka n’okulekera awo okugenda mu nsonga (amenorrhea) kiyinza okubaawo.
- Ku balenzi: Ekizimba bwe kikula ne kinyigiriza obusimu, kiyinza okuvaako okulumwa omutwe, obutalaba bulungi n’obuzibu obulala. Era kiyinza okuvaako okulwawo okutuuka mu myaka gy’obuvubuka oba obuzibu mu kukula.
Ensonga ki eziviirako kino?
Obulwadde bwa hyperpituitarism butera okuva ku kizimba mu nnywanto y’omubiri (pituitary gland). Tekinnamanyika ddala lwaki ebizimba bino bibaawo.
- Ebizimba ebitali bya bulabe: Kino kye kisinga okuvaako. Okusinziira ku kika ky’obutoffaali ekizimba kye kikoleddwamu, kitandika okufulumya obusimu bumu oba bubiri obuyitiridde.
- Embeera z’obuzaale: Oluusi, ebizimba bino bisobola okuva ku mbeera z’obuzaale nga Multiple Endocrine Neoplasia type 1 (MEN1) .
- Carcinoma: Tekitera nnyo, ekizimba kya kookolo oba obulwadde bwa hypothalamus busobola okuleeta kino.
Otegeera otya embeera eno?
Kati bw’ogenda ew’omusawo ng’alina obubonero buno, ajja kukwata ebyafaayo ebikwata ku bulwadde buno era awulirize obubonero bwo. Oluvannyuma lw’ekyo, bayinza okulagira okukeberebwa okuwerako okukakasa nti omuntu azuuliddwa.
- Okukebera omusaayi n’omusulo: Okukebera kuno kupima obusimu obuli mu musaayi oba mu musulo gwo. Ng’ekyokulabirako, bakebera emiwendo gya prolactin, cortisol, n’obusimu obuyamba omuntu okukula.
- Sikaani z’okukuba ebifaananyi: Singa okukeberebwa mu laabu kulaga nti waliwo ekizimba, sikaani eyinza okukolebwa okukikakasa. Kino kiyinza okulaga ddala ekizimba we kiri n’obunene bwe kiri.
- MRI (Magnetic Resonance Imaging) Scan: Eno y’enkola esinga okukozesebwa.
- CT (Computed Tomography) Scan: Bw’oba olina ekyuma ekikuba omukka, CT scan eyinza okukolebwa kubanga MRI tesobola kukolebwa.
Kijjanjabwa kitya?
Okusinziira ku mbeera yo, enkola emu oba eziwera ez’obujjanjabi ziyinza okukozesebwa awamu.
Eddagala
Mu mbeera ezimu, eddagala liweebwa okufuga emiwendo gy’obusimu. Okugeza mu mbeera y’obulwadde bwa prolactinoma, eddagala liweebwa okukendeeza ku prolactin n’okukendeeza ku kizimba. Eddagala era oluusi likozesebwa okukendeeza ku bizimba ebinene nga tebannalongoosebwa.
Okuloongoosa
Mu mbeera nga acromegaly oba Cushing’s syndrome, ekizimba kiggyibwamu nga balongoosebwa. Okulongoosa okusinga okuyitibwa transsphenoidal adenomectomy . Mu kino, omusawo alongoosa asala akatundu akatono okuyita mu nnyindo oba ku mimwa egya waggulu, n’atuuka mu nnywanto y’omubiri (pituitary gland) n’aggyawo ekizimba. Wadde nga kuno kulongoosebwa kwa maanyi nnyo, obuwanguzi busukka mu bitundu 80% bwe bukolebwa omusawo omukugu mu kulongoosa.
Obujjanjabi bw’amasannyalaze (radiation therapy).
Ku abo abatasobola kulongoosebwa, oba singa ebitundu by’ekizimba bisigalawo oluvannyuma lw’okulongoosebwa, bakozesa obujjanjabi obw’amasannyalaze. Kino kizingiramu okutunuulira ekitangaala ky’obusannyalazo obw’amaanyi amangi ku kizimba n’okusaanyaawo obutoffaali.
Endowooza eri etya?
Abantu bangi, endowooza y’embeera eno nnungi. Wadde nga tekisobola kuwona, singa kijjanjabwa n’okukiddukanya obulungi, abantu bangi basobola okufuga obubonero bwabwe ne babeera mu bulamu obulungi, obw’essanyu, era obuvaamu ebibala. Mu mbeera ezimu, kiyinza okwetaagisa okumira eddagala oba okumala ebbanga eddene ng’olabirirwa abasawo. Ekisinga obukulu kwe kusigala ng’okwatagana n’omusawo wo buli kiseera n’okumutegeeza ku nkyukakyuka yonna mu bubonero bwo.
Obubaka Obutwala Awaka
- Ensigo ya pituitary eringa "master controller" y'omubiri gwaffe. Obusimu bwe bufulumya bufuga emirimu mingi emikulu mu mubiri gwaffe.
- Singa endwadde eno ekola ekisusse, endwadde ez’enjawulo nga hyperpituitarism, Cushing’s syndrome, ne acromegaly zisobola okubaawo.
- Bw’olaba enkyukakyuka ez’amangu, ezitali za bulijjo mu bintu ng’obuzito bw’omubiri, enkula ya ffeesi, obutonde bw’olususu oba okugenda mu nsonga, kifaayo.
- Bw’oba olina obubonero buno, tosattira. Laba omusawo nga bukyali ofune amagezi.
- Singa embeera zino zizuuliddwa bulungi n’okuzijjanjaba, embeera zino nnyingi zisobola okufugibwa obulungi era abantu ne basobola okubeera mu bulamu obwa bulijjo.
