Uvavanyo lokukhuthaza ngasese

Uvavanyo lokukhuthaza ukhuselo lwe-secretin lulinganisa amandla epancreas okuphendula kwihomoni ebizwa ngokuba yi-secretin. Amathumbu amancinci avelisa i-secretin xa ukutya okwetyiswe ngokwesisu esisuka kwisisu kungena kuloo ndawo.

Umboneleli wezempilo ufaka ityhubhu ngeempumlo nakwisisu sakho. Umbhobho uhanjiswa kwinxalenye yokuqala yamathumbu amancinci (duodenum). Unikwa i-secretin ngomthambo (ngaphakathi). Amanzi aphuma kwi-pancreas aya kwi-duodenum asuswa ngombhobho ngaphezulu kwe-1 ukuya kwiiyure ezimbini.

Ngamanye amaxesha, ulwelo lunokuqokelelwa ngexesha le-endoscopy.

Uya kucelwa ukuba ungatyi okanye usele nantoni na, kubandakanya amanzi, iiyure ezili-12 ngaphambi kovavanyo.

Unokuba nemvakalelo yokugunxa njengoko ityhubhu ifakwa.

I-Secretin ibangela ukuba i-pancreas ikhuphe i-fluid equlethe i-enzymes yokugaya. Ezi enzymes ziqhekeza ukutya kwaye zinceda umzimba ukuba uthathe izondlo.

Uvavanyo lwe-secretin lokukhuthaza lwenziwa ukujonga umsebenzi wokugaya ukutya kwepancreas. Ezi zifo zilandelayo zinokuthintela i-pancreas ekusebenzeni ngokufanelekileyo:

• I-pancreatitis engapheliyo
• Icystic fibrosis
• Umhlaza wepancreatic

Kule meko, kunokubakho ukungabikho kwee-enzyme zokugaya ukutya okanye ezinye iikhemikhali kulwelo oluvela kwi-pancreas. Oku kunganciphisa amandla omzimba okwetyisa ukutya kunye nokufunxa izondlo.

Amaxabiso esiqhelo ahluka kancinci kuxhomekeka kwilebhu eyenza uvavanyo. Thetha nomboneleli wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Ixabiso elingaqhelekanga linokuthetha ukuba i-pancreas ayisebenzi kakuhle.

Kukho umngcipheko omncinci wokuba ityhubhu ibekwe ngombhobho kunye nasemiphungeni, endaweni yokungena kwi-esophagus nakwisisu.
