Cov kua qaub , kua txiv plab los yog plab acid , yog ib tug digestive kua tsim nyob rau hauv lub plab thiab yog tsim los ntawm hydrochloric acid (HCl), potassium chloride (KCl) thiab sodium chloride (NaCl). Cov hlwb no kuj tsim cov hnoos qeev, uas ua rau lub cev tsis muaj zog tiv thaiv cov kua qaub los ntawm lub plab.
Hauv qhov no, kuv tuaj yeem txo qis cov kua qaub hauv plab li cas?
Qhov no tuaj yeem tshem tawm cov tsos mob cuam tshuam nrog lub plab acid qis thiab pab tswj qib zoo hauv koj lub plab
- Txwv cov zaub mov tiav. Kev noj zaub mov zoo uas muaj txiv hmab txiv ntoo thiab zaub tuaj yeem ua rau koj cov qib acid ntau ntxiv.
- Noj zaub fermented.
- Haus kua txiv apple cider vinegar.
- Noj qhiav.
Tsis tas li ntawd, lub plab acid nyob hauv koj lub plab li cas? Cov plab yog acidic heev thiab zom cov zaub mov mus rau hauv ib qho ntxiv acidic paste hu ua chyme. Chyme txav los ntawm plab mus rau hauv duodenum (thawj ntu ntawm txoj hnyuv me) los ntawm pyloric sphincter. Qhov tseem ceeb, acidity ntawm chyme yog dab tsi ua rau pyloric sphincter qhib.
Kuj paub yog, ua li cas plab acid tsim?
Lub ntsiab lus tseem ceeb ntawm gastric acid yog hydrochloric kua qaub uas yog ua los ntawm parietal cells (tseem hu ua oxyntic cells) hauv plab hnyuv cov kab mob hauv lub cev plab . Lub cell parietal tso bicarbonate rau hauv cov hlab ntshav hauv cov txheej txheem, uas ua rau nce ib ntus ntawm pH hauv cov ntshav, paub tias yog cov dej alkaline.
Yuav ua li cas txaus ntshai yog mob plab?
Yog tsis kho, GERD tuaj yeem ua rau muaj teeb meem loj hauv lub sijhawm ntev, suav nrog kev pheej hmoo pheej hmoo ntawm mob qog noj ntshav. Raug raug rau plab acid tuaj yeem ua rau txoj hlab pas puas, ua rau: Txoj hlab pas: cov hlab ntawm txoj hlab pas tau ua paug, ua rau khaus, los ntshav, thiab ua rau mob hauv qee kis.
