Ngokwemvelo, kubhekwa njengobisi lwebele, kodwa, ngeshwa, hhayi kubo bonke abantwana. Umzimba wezingane ezinesifo se-lactase asikwazi ukungena futhi uthathe wonke amavithamini awusizo kanye nokulandelela okutholakala ebisi lwebele. Ngaphezu kwalokho, ukudla okunjalo kubangela ubuhlungu emanzini, izifo zesibalo kanye nezimpawu eziningi ezingathandeki. Masikhulume kabanzi mayelana nezimpawu zokuntuleka kwe-lactase ezinganeni ezisanda kuzalwa, ukuze sikwazi ukubona izibonakaliso ze-alamu ngesikhathi futhi hhayi ukukhulisa isimo semvuthuluka.
Izimpawu zokuntuleka kwe-lactase ezinganeni ezisanda kuzalwa
Ubisi lomama ngu-60% lactose. Ukuze uqonde, ama-pancreas izimpukane kufanele akhiqize i-enzyme ebizwa ngokuthi i-lactase. Uma lokhu kukhishwa kungenani okwanele, odokotela bakhuluma ngokuntuleka kwe-lactase. Lokhu ukwephulwa kungaba okuyisisekelo nesekondari. Izimpawu zokuntuleka kwe-lactase eyinhloko emntwaneni osanda kuzalwa kubonakala ngokushesha ngemva kwesicelo sokuqala esifubeni. Izimpawu eziphazamisayo kulokhu ziyi:
- ukuphindaphinda njalo nokuhlanza;
- isihlalo sobuhlaza obuhlaza okwesibhakabhaka nokungcola okwenziwe amhlophe, kuyilapho inani lokuphuma lingase lifinyelele izikhathi ezingu-10-12 ngosuku;
- ukwanda kwe-gassing ne-colic okubangelwa ukuvutshelwa esiswini;
- ukunyuka okuncane kwesisindo, kwezinye izimo, ukugoba ekuthuthukisweni.
Ukuvela ngisho nezibonakaliso ezimbalwa zokuntuleka kwe-lactase ezinsana kuyisenzakalo sokuhlolwa okuphelele futhi kuthathe izinyathelo eziphuthumayo.
Ukwelashwa kokuntuleka kwe-lactase ezinsana ezisanda kuzalwa
Ukutholakala "kokuntuleka kwe-lactase" akufanele kuzwakala abazali, njengombhalo. Ngokuvamile, ifakwa ngokushesha futhi isho ukwehlisa okwesikhashana umsebenzi we-enzyme. Iqiniso liwukuthi lesi sifo sinamafomu amaningi:
- Okuyinhloko - i-innate, noma i-pathology eqondile ngokwemvelo - iyinto engavamile kakhulu futhi ayikwazi ukuqedwa. Izingane ezinjalo ziboniswa: izingxube ezingenalo i-lactose; ubisi oluphansi lwe-lactose; amalungiselelo nge-enzyme engenamaphutha. Kodwa-ke, ngisho nalapho esekhulile, izingane ezinale ndlela yokugula ziyophoqeleka ukuba zishiye imikhiqizo yobisi.
- Izimpawu zokuntuleka kwe-lactase yesibili ezinsana zivela ngenxa yokutheleleka emathunjini, ama-virus, imithi, noma yiziphi ezinye iziphazamiso endleleni yokugaya, ngemva kokuthatha ama-antibiotic. Okunye nobufakazi bokuthi i-lactose engafanelekile ingenzeka ngenxa yokudla ngokweqile ubisi "obusweni". Lesi simo sishintshwa njengoba ugula oluyinhloko luphathwa noma umama ubeka indlela efanele yokudla. Ngakho-ke, ezimweni lapho umntwana enezibonakaliso zokuntuleka kwe-lactase, into yokuqala okudingeka uyilalele umama wakho ukuthi ngabe usebenza kahle yini esifubeni, kungakhathaliseki ukuthi umntanami uphonsa isifuba esisodwa ekupheleni, noma ubisi lwebele kuphela kusuka kokubili. Uma ukungabi khona kwe-enzyme kubangelwa ezinye izimbangela, odokotela bangakwazi ukubeka izidakamizwa eziqukethe i-lactobacilli ekhethekile eveza lactase.
Amalungiselelo enzyme nawo ayamukelekile. Ngokuvamile, ukungakwazi ukusebenza okwesikhashana kuyesikhashana futhi kuyanyamalala ngemuva kokuqeda imbangela ebalulekile. - Ukuntuleka kwe-lactase ehlala kancane emantwaneni, njengombuso, kubonakala kusenesikhathi sokubeletha. Lokhu kungenxa yokuthi imvelo ye-crumb ayisakalungiselelwa ngokwanele ukuphila ngaphandle kwesibeletho sikamama, ngakho-ke ayikhiqizi ama-enzyme adingekayo ekudleni kokudla. Ngokuhamba kwesikhathi, isimo, esizalwa ngaphambi kwesikhathi sezingane, siqinisa, futhi i-lactase iqala ukukhiqizwa ngokwanele.
