Uyu Muviri Ndiwo Unowanikwa Mavhithamini Akawanda neMaminari Akabviswa Zvokudya
Utumbo hudiki hutachiona hwakareba mamita makumi maviri, humwe chikamu chemuviri wekudya uye unobatanidza mudumbu uye mumukati mukuru . Nemhaka yokuti yakareba kwenguva refu, inofanira kushandura uye kutendeuka mudumbu. Mucheche muduku iyo inowanzochera kudya: mavhithamini akawanda nemaminerari, pamwe nemafuta uye mamwe mvura, anowanikwa mudumbu duku.
Tsvina yezvipfeko, inonzi peristalsis, shandisa zvokudya kuburikidza nemukati muduku sezvo ichigadzirwa.
Masikirwo mumukati maduku anoita basa rokuputsa zvokudya kune chikafu chemutengo. Izvozvo zvinokonzerwa nedzimwe nhengo uye zvino zvinopinda mumucheche maduku, kana dzakavanzwa nemukati mudumbu. Kana chikafu chikaputsika, chinogona kupinza uye kupinda ropa.
Zvikamu zveChipfuva Chediki
Utumbi muduku hwakakamurwa kuva zvikamu zvitatu zvikuru, uye zvakasiyana-siyana zvinotanga kuitika mune imwe neimwe. Zvikamu zvemukati mudumbu ndizvo:
- Duodenum: Chikamu chekutanga uye chiduku, chakangofanana ne "C." Zvokudya zvinopfuura kubva mudumbu kusvika kune duodenum kuburikidza nemusefu unonzi pyloric sphincter. Iron inopinza mu duodenum.
- Jejunum: Sug Sugar, amino acids, uye fatty acids zvinowanikwa munharaunda iyi yemukati muduku.
- Ileum: Ichi chikamu chokupedzisira chemukati mudumbu ndiko kunowanikwa vitamini B12, bile acids, nezvimwe zvinokonzera.
Zvokudya Zvakagadziriswa sei neChipfuva Chine Utachi
Ipakreas ndiyo inokonzerwa nemakemikari ekugadzirisa, uye inopfuudzwa nechitsiko kupinda mumukomana muduku.
Izvi zvinokonzera zvokudya kuitira kuti zvikwanise kugadziridzwa uye kushandiswa nemuviri. Mapuroteni, mafuta, uye mahydrohydrates zvinosvibiswa muzvikamu zvadzo uye zvakatorwa nevilli inowanikwa mu jejunum uye neyeum. Iyo villii zvivako zvinoputika kubva mukati memadziro emukati maduku seminwe kana vhudzi uye kutora mishonga.
Chirwere cheCrohn cheMucheche Muduku
Apo chirwere cheCrohn (chimwe chimiro chechirwere chirwere chinoputika, kana IBD ) chinokanganisa utumbo muduku, kunwa mavhithamini nemaminera zvinogona kuchinjwa.
Ileocolitis ndiyo inowanzozivikanwa yeCrohn's disease , uye ndiyo iyo chikamu chekupedzisira chemukati mudumbu uye mumukati mukuru zvinosanganiswa. Ileitis ndiyo iyo ya Crohn's disease iyo inokonzera ileum, uye ndiyo yechipiri inowanzojairika yeCrohn's disease. Vanhu vane ileocolitis kana ileitis vangave vasina kukwana mu vitamini B12 nokuti kuvhiringidza kunogona kudzivirira kupindira kwayo mueileum. Aya marudzi eCrohn's disease anogonawo kukonzera kushayikwa kwamavitamine ane mafuta (A, D, E, uye K), nokuti bile salts iyo inobatsira kutora mavhithamini aya anowanikwawo mueileum.
Jejunoileitis rudzi rwemhando shomanana rwechirwere chaCrohn chinokanganisa jejunum. Nemhaka yekuti kunyanya kudya kwevhitamini, zvicherwa, mapuroteni, mafuta, uye mahydrohydrates zvinowanikwa mu jejunum, kuputika mune chikamu chemukati mudumbu kunogona kutungamirira kuwandu hwakawandisa hwekudya.
Chirwere cheGastroduodenal Crohn ndechimwe chimiro chisina kujairika chechirwere chinokonzera duodenum (pamwe chete nedumbu).
Maminerari anogona kuchinjwa anosanganisira iron, calcium, uye magnesium, nokuti zvose zvinoputirwa mu duodenum.
Icho Chidiki Chinyanya uye I-J-Pouch
J-pouch chirurgic (inonziwo yeal pouch kana anal anastomosis (IPAA) kuvhiyiwa) inoitwa kurapa ulcerative colitis kana yemhuri adenomatous polyposis (FAP). Mukuvhiya uku, koni yacho inobviswa uye ileamu inoshandiswa kugadzira chikwama chakaumbwa se "J" (dzimwe nguva "S" kana "W" ingasikwawo). Nemhaka yokuti j-pouch yakasikwa kubva payeeum, kana ikazoguma yakazara (yakadai nemhaka ye pouchitis), zvirwere zve vitamini uye zvicherwa zvinogona kuitika.
Zvimwe Zvirwere uye Mamiriro Ezvakawanda zveAtestine
Kunze kwechirwere chaCrohn, zvirwere zvakasiyana siyana uye mamiriro ezvinhu zvinogona kukanganisa utumbo muduku, kusanganisira:
- Bowel obstructions
- Chirwere cheCeliac
- Gastroenteritis
- Zvirwere
- Kanzo dzomukumbo
- Utumbo hunokanganisa-kuvhiringidza
- Lactose kusawirirana
- Polyps
- Ulcers
