"Gqirha, umhlobo wam uthe wachacha emva kwesiqingatha seyure emva kokusela ipilisi eyayinikwe ngugqirha ngenxa yentloko yakhe ebuhlungu. Kamva, kwafumaniseka ukuba yayiyi-placebo equlethe iswekile nomgubo kuphela. Ipilisi yomgubo inganyanga njani isifo? Ingaba ngumlingo?" URuwan oneminyaka engama-30 ubudala wabuza uGqirha Priya emangalisiwe kwikliniki yethu.
UGqr. Priya wancuma kancinci waza wachaza, "Ruwan, oko kubizwa ngokuba yiPlacebo Effect. Oku akuyomilingo. Inkolelo eqinileyo kunye nolindelo lokuba unyango oluthile okanye iyeza liza kuzisa unyango ludala utshintsho lweekhemikhali engqondweni yethu. Elo nyango lwenzeka kuba ingqondo ngokwendalo ikhupha iihomoni eziphelisa iintlungu ezifana nee-endorphins."
Iingcinga neenkolelo zethu zingaphilisa njani imizimba yethu? Kweli nqaku, siza kuxoxa ngokufutshane ngemfihlo yezonyango neyesayensi engasemva kwePlacebo Effect kunye nophando olumangalisayo olwenziwe zizazinzulu kwiYunivesithi yaseMcGill eKhanada.
Yintoni i-Placebo Effect?
Iqela lezazinzulu kwiRaz Lab edumileyo kwiYunivesithi yaseMcGill eMontreal, eKhanada, lenze uphando olumangalisayo. Injongo yayikukuhlola amandla omzimba okuziphilisa ngokwawo ngonyango olungelulo olwemithi.
I-placebo lunyango olungeyonyani olungenazo izithako ezisebenzayo zonyango, ngokuqhelekileyo ipilisi eyenziwe ngeswekile okanye ngomgubo, inaliti esekwe emanzini, okanye isixhobo esingeyonyani.
Isiphumo se-placebo sifumaneka xa isigulane sinikwa iyeza ekuthiwa liyeza lokwenyani, size isigulane sikholelwe ukuba liyeza lokwenyani size silisebenzise, kwaye iimpawu ziyaphucuka ngokwenene.
Kwenzeka njani oku? Umxholo wophuhliso
Izazinzulu zithi oku kusenokuba ngumphumo wokuvela komntu. Kumaxesha amandulo, xa indoda igula, yayifumana unyango kunye nonyango kwamanye amalungu.
Xa ufumana olu nyango, inkqubo yokuzikhusela yomzimba iyakhuthazwa kwaye amathuba okuphiliswa kwesi sifo ayanda. Ke ngoko, ingqondo yomntu yenzelwe ukukhawulezisa inkqubo yendalo yokuphiliswa komzimba xa ifumana uphawu lokuba kukho umntu oyinyangayo.
Isiphumo sonyango siyahluka ngokuxhomekeke kwimilo, umbala, kunye nendlela (Amandla okuqonda)
Impumelelo yonyango lwe-placebo iyahluka ngokuxhomekeke kwindlela olubamba ngayo izivamvo ezintlanu zesigulana:
- Umbala wepilisi: Ipilisi ye-placebo enikwa njengepilisi yokulala isebenza kakuhle xa iluhlaza okwesibhakabhaka, kwaye ipilisi ye-placebo enikwa njengepilisi yokuvuselela isebenza ngcono xa ibomvu okanye ityheli.
- Ubungakanani kunye nokuma: Ipilisi yobuxoki ekwimo yekhaphu inamandla ngakumbi kunepilisi eqhelekileyo.
- Indlela yokusetyenziswa: Inaliti ye-placebo iya kunyanga isifo ngokukhawuleza kuneepilisi ezimbini ze-placebo.
🏥 Uphononongo lweMcGill Sham MRI: Uphononongo oluyintshatsheli lwabantwana olwenziwe ngoososayensi beMcGill
Izazinzulu kwiYunivesithi yaseMcGill zenze uphando zisebenzisa iqela labantwana abanengxaki yezifo ezifana ne-asthma, i-migraine, kunye ne-attention deficit hyperactivity disorder (ADHD).
Baxelele abantwana abagulayo ukuba banyangwa kusetyenziswa umatshini we-MRI wanamhlanje (uMatshini we-MRI weSham) onokutshintsha ukusebenza kwengqondo kwaye unyange esi sifo. Kodwa esi sixhobo sasisixhobo sobuxoki esasingenamsebenzi kwaye sikhupha izandi ngaphakathi kuphela.
Abantwana bafakwa kulo matshini baza banikwa unyango lokuskena olungekho mthethweni kangangeeveki ezi-6. Okumangalisayo kukuba, emva kweeveki ezi-6, ngaphezulu kwe-70% yeempawu zabantwana zaphela. Abantwana babekholelwa ukuba baphiliswe ngumatshini wokwenyani, kodwa eneneni baphiliswe ngamandla eengqondo zabo.
🚨 Imida kunye neeMpawu eziBomvu zoNyango lwePlacebo
Nangona isiphumo se-placebo sinamandla kakhulu, ukusetyenziswa kwaso kufuna ulwalathiso olusondeleyo lwezonyango:
- Umhlaza kunye nosulelo olunzima: Unyango lwe-placebo alunakusetyenziswa kwizifo ezifuna unyango lomzimba, njengomhlaza, usulelo lweebhaktheriya, okanye isifo sentliziyo.
- Intlungu kunye neempawu zengqondo: Ii-placebos zinokunyanga kuphela iimpawu ezilawulwa ziimpawu zobuchopho, ezinje ngentlungu, ukudinwa, uxinzelelo kunye nokucaphuka.
- Ukungawunaki ulwalathiso lwezonyango: Ukuthembela kuphela kwii-placebos okanye kunyango olungelulo olunye endaweni yonyango lokwenyani kunokuba yingozi ebomini.
🛠️ Amanyathelo Okusebenza okuphuhlisa amandla engqondo kunye nobuhle bengqondo
- Inyathelo Lokuqala: Xa ugula, phuhlisa ingcinga enamandla eyakhayo, "Ndiza kuphila kungekudala," ngelixa usela amayeza owanikwe ngugqirha.
- Inyathelo lesiBini: Themba ugqirha onyangayo. Ubudlelwane obuhle phakathi kogqirha nesigulana bunceda ekuvuseleleni isiphumo se-placebo.
- Inyathelo Lesithathu: Zibandakanye kwimisebenzi efana nokucamngca, ukuzilolonga okulula, okanye i-yoga ukunciphisa uxinzelelo kunye nexhala. Le misebenzi inceda ekuveliseni i-dopamine yehomoni emnandi emzimbeni.
- Inyathelo Lesine: Sela amayeza akho ngexesha elifanelekileyo nangedosi efanelekileyo. Ukusela amayeza akho njengesiqhelo kuqinisa ithemba lokuchacha engqondweni.
📊 Uhlu lwePlacebo kunye neNocebo
| Unyango (Uhlobo) | Impembelelo emzimbeni | Umzekelo |
|---|---|---|
| Isiphumo sePlacebo | Ukulindela okuhle kubangela ukuba ingqondo ikhuphe ii-endorphin kwaye izive kamnandi. | Ukuphelisa intloko ebuhlungu ngokuthatha iipilisi zeswekile. |
| Isiphumo sikaNocebo | Ukulindela okubi okanye uloyiko olukhokelela kwimiphumo emibi. | Ukugabha emva kokuthatha ipilisi yobuxoki, ucinga ukuba iza kubangela iziphumo ebezingalindelekanga. |
| Utyando lweSham | Isigulana siyathomalaliswa kwaye kuphela umphezulu wesikhumba osikiweyo nothungelweyo. | Ukunciphisa iintlungu ngokwenza utyando lobuxoki ngexesha lotyando lwe-arthritis edolweni. |
❓ Eminye imibuzo onokuba nayo (FAQ)
Ngaba ukuthatha ipilisi ye-placebo kuyawenza umahluko emzimbeni wakho ?
Ewe. Isiphumo se-placebo sibangela ukuba ingqondo ikhuphe iikhemikhali zendalo ezifana nee-endorphins kunye ne-dopamine, kwaye isantya sentliziyo kunye noxinzelelo lwegazi zibuyela kwisimo esiqhelekileyo. Oku akusiyongcinga nje, kodwa lutshintsho lokwenyani lwe-physiological olwenzeka emzimbeni.
Yintoni iNocebo Effect? ▼
Oku kuchasene nesiphumo se-placebo. Ukuba isigulane asinathemba malunga nonyango okanye sinoloyiko olukhulu lweziphumo ebezingalindelekanga, sinokufumana iimpawu ezimbi ezifana nesicaphucaphu, isiyezi, okanye iintlungu zesisu nokuba sithatha ipilisi ye-placebo engenazo izithako ezisebenzayo.
Kutheni ii-placebos zisetyenziswa kuphando lwezonyango lwanamhlanje?
Xa kufunyaniswa iyeza elitsha, kusetyenziswa i-placebo ukulinganisa impembelelo yalo yokwenyani kwezonyango. Izigulane zahlulwe zibe ngamaqela amabini kwaye elinye iqela linikwa iyeza lokwenyani kwaye elinye iqela linikwa ipilisi ye-placebo. Eli yeza lithathwa njengelisebenzayo kuphela ukuba iqela elithatha iyeza lokwenyani liphucuka kakhulu kuneqela elithatha i-placebo.
Ngaba kulungile ukunika ii-placebo kuphela kwizifo zokwenyani ?
Kwimisebenzi yesiqhelo yezonyango, akulunganga ukunika izigulana ii-placebos ngobuqhetseba. Nangona kunjalo, kukho iimeko apho oogqirha ngamanye amaxesha banika izigulana izinto ezifana neepilisi zeevithamini njengee-placebos, nokuba bazisiwe okanye bengazixelelwanga, ukulawula iimpawu ezingezizo ezinzulu okanye ezibangelwa luxinzelelo.
