THE jekiseni ndiwo hormone zvakasikwa zvinogadzirwa ne rwatata mukupindura kuwedzera kwehuwandu hweshuga (glucose) muropa.

Insulin ine chiito " hypoglycemiante ", Kureva, inoderedza huwandu hweshuga yeropa, shuga dzeropa. Muchokwadi, "inotaurira" masero emuviri kutora glucose, iyo inobatsira kudzikamisa mwero unotenderera muropa.

Iyo ine inopesana nemhedzisiro kune glucagon, imwe pancreatic hormone iyo inokonzera kuwedzera ropa glucose (hyperglycaemic basa). Insulin uye glucagon zvinoshanda pamwechete kuchengetedza shuga zveropa dzakatenderedza 1g / L nguva dzese.

Mune chirwere cheshuga, ichi chiyero chakatsamwa. Insulini inogadzirwa mune mashoma huwandu, uye / kana maseru haanyanye kuifarira (mhedzisiro yacho saka haina simba).

Muyero we insulin muropa (insulinemia) haishandisirwe kuongororwa kana kuongorora chirwere cheshuga (chinoenderana nekuongororwa kweshuga yeropa uye glycated hemoglobin).

Nekudaro, zvinogona kubatsira kuyedza iyo insulini muropa kuti uzive kugona kwepancreas kuburitsa insulin (izvi zvinogona kubatsira chiremba pane mamwe matanho echirwere cheshuga).

Kuongorora uku kunogona kuitwawo muchiitiko chekudzokorora hypoglycaemia. Inogona kubatsira kuona insulinoma (isina kujairika endocrine pancreatic bundu), semuenzaniso.

Kazhinji, chiremba anorayira "pancreatic assessment", ndiko kuti, kuongororwa kwemahomoni epancreatic anosanganisira insulin, C-peptide, proinsulins uye glucagon.

Insulin inoedzwa nekutora ropa murabhoritari yekuongorora yekurapa. Izvo zvakakosha kuti utsanye kuitira kuongororwa kweropa kuti uzive iyo "basal" muyero.

Nekudaro, iyi ongororo kazhinji haina kukwana. Sezvo kuvharika kwe insulin kuchishanduka kwazvo mumunhu mumwe chete mukati mezuva, chiyero chakasarudzika chinonetsa kududzira. Insulin kuyedza saka kunowanzoitwa mushure meyesimba bvunzo senge yemuromo hyperglycemia (OGTT), uko murwere anopiwa mhinduro inotapira yekumwa kuti aone kuti muviri wavo uri kupindura sei.

Mhedzisiro yacho inopa chiremba kutungamira pane iyoinsulinosécrétion, kureva kuti secretion ye insulin ne rwatata, kunyanya mushure mekutapira "kudya".

Segwara, pane isina chinhu mudumbu, insulinemia kazhinji iri pasi pe25 mIU / L (µIU / mL). Icho chiri pakati pe30 uye 230 mIU / L maminetsi makumi matatu mushure mekuitiswa kweglucose.

Kana iri insulinoma, semuenzaniso, ichi chinyadzo chichava chakakwira zvisina kujairika, zvichiramba zvichikonzera kudzokororwa kwehypoglycaemia.

Chiremba chete ndiye anogona kududzira zvabuda uye akupe chirwere.
