Kodi pyloric sphincter ndi chiyani?

Mmimba muli china chotchedwa pylorus, chomwe chimalumikiza m'mimba ndi duodenum. Duodenum ndiye gawo loyamba la m'matumbo ang'onoang'ono. Pamodzi, pylorus ndi duodenum zimagwira gawo lofunikira pothandiza kusuntha chakudya kudzera munjira yogaya chakudya.

Pyloric sphincter ndi gulu losalala lomwe limayendetsa mayendedwe azakudya zopukutidwa pang'ono ndi timadziti kuchokera ku pylorus kupita ku duodenum.

Kodi ili kuti?

Pyloric sphincter ili pomwe pylorus imakumana ndi duodenum.

Onani zowonera 3-D pansipa kuti mudziwe zambiri za pyloric sphincter.

Ntchito yake ndi yotani?

The pyloric sphincter imagwira ntchito ngati njira yolowera pakati pamimba ndi m'mimba. Amalola zomwe zili m'mimba kudutsa m'matumbo ang'onoang'ono. Zimatetezeranso chakudya chopukusidwa pang'ono ndi timadziti ta m'mimba kuti tisabwerenso m'mimba.

Mbali zakumunsi zam'mimba zimalumikizana ndi mafunde (otchedwa peristalsis) omwe amathandiza kuwononga chakudya ndikusakaniza ndi timadziti. Kusakaniza kwa chakudya ndi timadziti timene timagaya timatchedwa chyme. Mphamvu ya zopendekera izi imakulira kumunsi kwam'mimba. Ndi funde lililonse, pyloric sphincter imatseguka ndikulola pang'ono chyme kuti ilowe mu duodenum.

Pamene duodenum imadzaza, imapanikiza pyloric sphincter, ndikupangitsa kuti izitseka. Kenako duodenum imagwiritsa ntchito peristalsis kusuntha chyme kupyola m'matumbo onse. Duodenum ikakhala kuti ilibe kanthu, kupanikizika kwa pyloric sphincter kumatha, kulola kuti itsegulenso.

Ndi zikhalidwe ziti zomwe zimakhudza izi?

Reflux wamadzi

Reflux yamadzimadzi imachitika ndulu ikamabwerera m'mimba kapena m'mimba. Bile ndi madzi am'mimba opangidwa m'chiwindi omwe nthawi zambiri amapezeka m'matumbo ang'onoang'ono. Pyloric sphincter ikakhala kuti siyigwire bwino ntchito, bile imatha kukwera m'mimba.

Zizindikiro za bile reflux ndizofanana kwambiri ndi asidi Reflux ndipo zimaphatikizapo:

• kupweteka kwa m'mimba
• kutentha pa chifuwa
• nseru
• masanzi obiriwira kapena achikasu
• chifuwa
• kuonda kosadziwika

Matenda ambiri a bile reflux amayankha bwino mankhwala, monga proton pump inhibitors, ndi maopaleshoni omwe amagwiritsidwa ntchito pochizira acid reflux ndi GERD.

Pyloric stenosis

Pyloric stenosis ndi chikhalidwe mwa makanda omwe amaletsa chakudya kulowa m'matumbo ang'onoang'ono. Ndi zachilendo zomwe zimakonda kuyenda m'mabanja. Pafupifupi 15% ya makanda omwe ali ndi pyloric stenosis ali ndi mbiri ya banja la pyloric stenosis.

Pyloric stenosis imaphatikizapo kukulira kwa pylorus, komwe kumalepheretsa chyme kudutsa pyloric sphincter.

Zizindikiro za pyloric stenosis ndi izi:

• kusanza mwamphamvu mutadyetsa
• njala itatha kusanza
• kusowa kwa madzi m'thupi
• chimbudzi chaching'ono kapena kudzimbidwa
• kuonda kapena mavuto onenepa
• kupweteka kapena ziphuphu pamimba mutatha kudyetsa
• kupsa mtima

Pyloric stenosis imafuna kuchitidwa opaleshoni kuti ipange njira yatsopano yomwe imalola kuti chyme idutse m'matumbo ang'onoang'ono.

Gastroparesis

Gastroparesis imalepheretsa m'mimba kutulutsa bwino. Mwa anthu omwe ali ndi vutoli, mafunde ofanana ndi mafunde omwe amasuntha chyme kudzera munjira yogaya chakudya amafowoka.

Zizindikiro za gastroparesis ndi monga:

• nseru
• kusanza, makamaka chakudya chosagayidwa mukangodya
• kupweteka m'mimba kapena kuphulika
• Reflux ya asidi
• kumva kukhuta mutadya pang'ono
• kusinthasintha kwa shuga wamagazi
• kusowa chakudya
• kuonda

Kuphatikiza apo, mankhwala ena, monga opioid ululu amachepetsa, amatha kukulitsa zizindikilo.

Pali njira zingapo zochizira gastroparesis, kutengera kukula kwake:

• kusintha kwa zakudya, monga kudya kangapo patsiku kapena kudya zakudya zochepa
• kuwongolera kuchuluka kwa magazi m'magazi, mwina ndi mankhwala kapena kusintha kwa moyo
• kudyetsa chubu kapena michere yolowa mkati kuti muwonetsetse kuti thupi limapeza ma calories ndi michere yokwanira

Mfundo yofunika

Pyloric sphincter ndi mphete yosalala yolumikizira m'mimba ndi matumbo ang'onoang'ono. Amatsegula ndikutseka kuti azitha kuyendetsa zakudya zopukusidwa pang'ono ndi timadziti m'mimba kuchokera ku pylorus kupita ku duodenum. Nthawi zina, pyloric sphincter imakhala yofooka kapena siyigwira bwino ntchito, zomwe zimabweretsa mavuto am'mimba, kuphatikizapo bile reflux ndi gastroparesis.
