Sonke sijwayelene nomuzwa wobuhlungu emizimbeni yethu, ikakhulukazi imisipha yethu, ngemva kosuku olunzima lokuzivocavoca noma ngemva kokusebenza kanzima endlini. Abantu abaningi bacabanga ukuthi imbangela yalokhu buhlungu ukuqongelela kwamakhemikhali okuthiwa 'i-lactic acid' emzimbeni. Kodwa ingabe kunjalo ngempela? Namuhla, ake sifunde ngqo nge-lactic acid, abantu abaningi abangayiqondi kahle.
Kalula nje, iyini i-lactic acid?
I-lactic acid iyikhemikhali ekhiqizwa umzimba wakho lapho amaseli akho ephula ama-carbohydrate ukuze athole amandla. Ngezinye izikhathi ibizwa ngokuthi i-lactate. Ivame ukukhiqizwa amaseli emisipha yakho namaseli abomvu egazi, kodwa empeleni ingakhiqizwa yinoma yisiphi izicubu emzimbeni wakho.
Abantu abaningi bazi kuphela nge-lactic acid njengento eyenzeka ngesikhathi sokuzivocavoca. Yebo, uma usebenza kanzima, wenza umsebenzi wasegcekeni, noma uphakamisela umngane umthwalo, imisipha yakho ikhiqiza i-lactic acid eningi. Lokho kungenxa yokuthi umzimba wakho awukwazi ukusebenzisa umoya-mpilo ukukhiqiza amandla njengoba ubungawenza ngokuvamile.
Cabanga ngakho, umzimba wakho unezindlela ezimbili zokukhiqiza amandla. Enye iwukukhiqiza amandla usebenzisa umoya-mpilo (i-aerobic). Enye iwukukhiqiza amandla ngokushesha ngaphandle komoya-mpilo (i-anaerobic). Uma ngokuzumayo wenza into efana nokugijima noma ukuphakamisa isisindo, umzimba wakho awukwazi ukunikeza umoya-mpilo ngokushesha njengoba udinga. Yilapho umzimba wakho ushintshela endleleni yesibili. Umphumela ongemuhle wale ndlela yesibili yi-lactic acid.
Kodwa lokhu kwanda kwesikhashana kwamazinga e-lactic acid akulona ingozi nhlobo . Ngokuvamile akubangeli zimpawu. Isibindi nezinso zakho zihlunga le lactic acid eningi egazini lakho bese ziyiguqula ibe ushukela, obizwa ngokuthi i-glucose, ongasetshenziswa njengamandla.
Ngakho-ke i-lactic acid akuyona into embi?
Lutho neze! I-lactic acid iyinto ebaluleke kakhulu emzimbeni wethu. Akuyona nje imfucuza. Yenza imisebenzi eminingana ebalulekile.
| Imisebenzi eyinhloko ye-lactic acid | Okunye kumane nje... |
|---|---|
| Ukunikeza amandla | Uma amangqamuzana akho esebenza kakhulu, njengasesikhathini sokuzivocavoca, i-lactic acid iyasiza ekuhlinzekeni amandla asheshayo awadingayo. |
| I-Gluconeogenesis | I-lactic acid ekhiqizwa emisipheni ihamba ngegazi iye esibindini nasezinso, lapho iguqulwa khona ibe ushukela bese igcinwa emzimbeni ukuze isetshenziswe kamuva njengamandla. |
| Isebenza njenge-molecule yokubonisa | I-lactic acid ifana nesiginali ethwala imiyalezo emzimbeni wonke. Cabanga ngayo njengokumaka umgwaqo ngamafulegi lapho usebenza. Uma kukhona ukulimala noma ukutheleleka, i-lactic acid yiyona etshela amasosha omzimba ukuthi "eze lapha" ukuzophulukisa leyo ndawo. |
Ngakho-ke, akuyona yini ngempela i-lactic acid ebangela ubuhlungu bemisipha?
Lona umbono ongalungile omkhulu phakathi kwabantu abaningi. Cha, i-lactic acid ayiyona imbangela yobuhlungu bemisipha obuvela ngosuku noma ezimbili ngemva kokuzivocavoca.
Esikhathini esidlule, ngisho nodokotela babecabanga ukuthi i-lactic acid iyona imbangela yalobu buhlungu. Kodwa ucwaningo olusha luthole ukuthi i-lactic acid isuswa emisipheni ngemizuzu embalwa yokuzivocavoca. Ngakho ayinaso isikhathi sokulimaza amangqamuzana noma ukubangela ubuhlungu.
Lobuhlungu empeleni bubangelwa ukudabuka okuncane (ama-microtears) emicu yemisipha yakho uma uzivocavoca kanzima. Lokhu kuyinto enhle. Ngoba njengoba umzimba ulungisa lokhu kudabuka okuncane, imisipha ikhula ibe mikhulu futhi ibe namandla kunangaphambili. Kodwa-ke, uma uzwa ubuhlungu obukhulu , kungaba yisimo esibizwa ngokuthi ukucindezelwa kwemisipha. Ezimweni ezinjalo, kubalulekile ukuphumula nokufuna iseluleko sikadokotela uma kudingeka.
I-lactic acidosis ingaba yisimo esiyingozi.
Kunezinhlobo ezimbili zezimo ezingabangela ukwanda kwesikhashana kwamazinga e-lactic acid ngesikhathi sokuzivocavoca: i-lactic acidosis.
I-Lactic acidosis yisimo lapho izinga le-lactic acid egazini liba phezulu ngendlela eyingozi lapho umzimba ungakwazi ukususa kahle i-lactic acid eningi ekhiqizwayo. Lesi yisimo esibi kakhulu, ngezinye izikhathi esisongela ukuphila.
Lokhu kuvame ukwenzeka njengenkinga yesinye isimo sezokwelapha esiyisisekelo.
- Ukwehluleka kwezinso
- Ukwehluleka kwesibindi noma i-cirrhosis
- Ukwehluleka kwenhliziyo
- Ukutheleleka okukhulu kanye ne-sepsis
- Ezinye izimo zomdlavuza
| Izimpawu ezivamile ze-lactic acidosis | |
|---|---|
| Isicanucanu nokuhlanza | Umzimba uzama ukususa i-asidi eningi ngokushesha okukhulu. |
| Ubuthakathaka | Ukuzizwa ungenampilo, ikakhulukazi emisipheni. |
| Isisu esibuhlungu | Ubuhlungu besisu noma ukungakhululeki. |
Into ebaluleke kakhulu ukuthi akufanele neze uzishaye indiva lezi zimpawu, ikakhulukazi uma unezinye izimo zezokwelapha ezifana nesifo sikashukela noma isifo sezinso. Lesi yisimo esiphuthumayo sezokwelapha. Kufanele uye eMnyangweni Wezimo Eziphuthumayo wesibhedlela (ETU) ngokushesha okukhulu.
Amazinga e-lactic acid alinganiswa kanjani?
Uma udokotela wakho esola ukuthi une-lactic acidosis, uzokwenza ukuhlolwa kwegazi ukuqinisekisa ukuxilongwa. Lokhu kuzolinganisa inani le-lactic acid egazini lakho. Udokotela uzobe esenquma ukuthi yiluphi ukwelashwa okudingekayo ngokusekelwe emiphumeleni.
Ngaphezu kwalokho, kukhona ukuhlolwa okukhethekile kwabadlali okubizwa ngokuthi 'i-Lactate Threshold Test'. Lokhu kwenzelwa ukusiza umdlali ukuthi azi umkhawulo wakhe omkhulu wokukhuthazela futhi aqeqeshe ngokuphephile. Lokhu kuhlolwa kumele kwenziwe ngaphansi kokuqashwa ngudokotela.
Ingabe i-lactic acid iyindlela yokulawula ukukhulelwa?
Lokhu kuhle futhi ukwazi. Ezinye izindlela zokuvimbela inzalo zincoma ijeli ekhethekile yesitho sangasese sowesifazane equkethe i-lactic acid, i-citric acid, kanye ne-potassium bitartrate. Lokhu kuyinto efakwa esitho sangasese sowesifazane ngaphambi kocansi. Kodwa-ke, lokhu kuhluke ngokuphelele ku-lactic acid ekhiqizwa ngumzimba wakho ngokwemvelo.Amazinga ajwayelekile e-lactic acid akhiqizwa emzimbeni awathinti ukukhulelwa.
Umlayezo Wokuya Nawe Ekhaya
- I-lactic acid akuyona into elahlwayo, kodwa iwuphethiloli kanye nesignali enikeza umzimba amandla, isize ukuthi ululame, futhi iyisandulela sokuzivocavoca.
- Ubuhlungu bemisipha obuvela ezinsukwini ezimbalwa ngemva kokuzivocavoca akubangelwa yi-lactic acid, kodwa ukudabuka okuncane okwakheka emisipheni.
- I-Lactic acidosis yisimo esibi sezokwelapha esingase senzeke nakwezinye izimo zezokwelapha. Akufanele ididaniswe nokuzivocavoca okuvamile.
- Uma unezimpawu ezifana nokucanuzela kwenhliziyo, ukuhlanza, noma ubuthakathaka obukhulu, ikakhulukazi uma unezinye izifo, bona udokotela ngokushesha .
- Indlela engcono kakhulu yokuzivikela ekulimaleni kwemisipha iwukuzifudumeza kahle ngaphambi kwanoma yikuphi ukuzivocavoca nokuzibandakanya njalo ekuzilolongeni umzimba .
