Lactase deficiency yog dab tsi? Qhov no yog ib yam mob ntawm lub cev (tau los yog congenital) nyob rau hauv uas lub lactase enzyme nyob rau hauv txoj hnyuv muaj ib tug tsis muaj zog ua hauj lwm. Yog li ntawd, lactose (disaccharide, mis nyuj qab zib) tsis tuaj yeem tawg thiab nqus tau. Tab sis nws yog ib qho tseem ceeb rau kev loj hlob ntawm tus me nyuam lub cev nyob rau hauv thawj lub hlis
s ntawm lub neej, vim nws yog lub hauv paus ntawm lub zog (muab txog 40% ntawm qhov xav tau). Cov mis nyuj muaj qhov siab ntawm lactose - txog 85%.
Yog tias lactose intolerance tshwm sim hauv cov menyuam yug tshiab, cov tsos mob tsis zoo. Lawv qhov xwm txheej yog dab tsi? Lactase yog ib qho enzyme tshwj xeeb uas muaj peev xwm zom cov lactose. Enterocytes (cov cell ntawm plab hnyuv epithelial cov ntaub so ntswg) pab tswj nws cov haujlwm siab. Yog tias cov mucosa puas lawm, yog li ntawd, kev ua haujlwm lactase yuav qis thiab kev nqus lactose yuav tsis zoo. Cov undigested lactose ces nkag mus rau hauv txoj hnyuv loj. Thiab yuav ua rau muaj kev tsis sib haum xeeb hauv microflora. Thiab qhov no yuav ua rau pom cov tsos mob tsis zoo ntawm tus kab mob, qaug zog ntawm lub cev nrog cov organic acids (methane, carbon dioxide, hydrogen), thiab kev tsim tawm ntawm cov kab mob pathogenic..
Lactose intolerance tuaj yeem yog ib nrab (hypolactasia) lossis ua tiav (alactasia). Kuj tseem muaj cov ntaub ntawv zoo li no ua thawj thiab theem nrab. Nyob rau hauv thawj rooj plaub, lub pathology yog vim ib tug genetic predisposition rau tus kab mob, tsis muaj feem xyuam rau kev sib deev ntawm tus me nyuam. Hauv qhov thib ob (nws yog ntau dua), qhov ua rau yog qhov ua rau tsis zoo ntawm txoj hnyuv plab enzymes hauv cov menyuam mos ntxov ntxov, kev siv tshuaj hormones, tshuaj tua kab mob, kab mob plab hnyuv, ua xua.
Lactose deficiency hauv cov menyuam mos: cov tsos mob
- High degree of gas formation.
- plab hnyuv.
- Ntse regurgitation tom qab noj.
- -plab hnyuv (colic).
- Teeb meem quav (defaecation): cem quav, "ua npuas ncauj" quav.
- Nyob qhov hnyav nce.
- pw tsis tsaug zog, kua muag.
- Delayed psychomotor development.
Lactase deficiency hauv cov menyuam mos: kev kho mob
Tam sim no txoj hauv kev tseem ceeb ntawm kev kho cov kab mob no yog kev noj zaub mov. Nws muab kev cais tawm ntawm lactose los ntawm tus menyuam noj. Tab sis li cas txog cov me nyuam mos? Tseeb, nyob rau hauv cov poj niam cov mis nyuj thiab sib tov, carbohydrates yog sawv cev precisely los ntawm lactose. Yog li ntawd, nyob rau hauv feem ntau, cov me nyuam tsuas yog muab tshuaj lactase enzyme, uas tso cai tsis taucuam tshuam kev pub niam mis, zam cov tsos mob tsis zoo. Thiab nyob rau hauv cov ntaub ntawv ntawm cov khoom noj khoom haus, sib tov nrog ib feem me me ntawm lactose los yog lactose-dawb (nrog rau tag nrho intolerance) yog sau.
Thaum kuaj pom tias tsis muaj lactose intolerance nyob rau hauv cov menyuam mos, cov tsos mob yuam kom hloov kev noj haus kom sai li sai tau. Feem ntau, nws yuav siv sijhawm 2-3 hnub los hloov tus menyuam mus rau qhov sib xyaw tshwj xeeb. Txhawm rau kho tus qauv pub niam mis tshiab, 1/3 ntawm cov zaub mov yuav tsum tau hloov.
Txhawm rau kom paub tseeb tias muaj lactose tsis txaus hauv cov menyuam yug tshiab, cov tsos mob yuav tsum tau lees paub los ntawm kev xeem dhau qhov tsim nyog:
- kawm txog quav rau qib carbohydrates, lactic acid, pH;
- noj cov qauv provocative nrog lactose (kom txiav txim siab npaum li cas ntawm hydrogen nyob rau hauv exhaled cua).
