Peptide C, izwi kandi nka peptide ihuza, ni aside amine y'ingenzi mu gukora insuline. Irekurwa na pancreas hamwe na insuline kandi ikaba ikimenyetso cy'ingenzi cyo gusuzuma imikorere ya pancreas. Nubwo insuline igenzura urugero rw'isukari mu maraso, C-peptide igira uruhare rutandukanye kandi ni ingenzi mu gusobanukirwa indwara zitandukanye, cyane cyane diyabete. Mu gupima urugero rwa C-peptide, abakora mu buvuzi bashobora gutandukanya diyabete yo mu bwoko bwa 1 n'iya 2, kuyobora ibyemezo byo kuvura, no kugenzura imikorere y'ubuvuzi.

Gupima urugero rwa C-peptide ni ingenzi mu gusuzuma no kuvura diyabete. Abantu barwaye diyabete yo mu bwoko bwa 1 bakunze kugira urugero ruto rwa insuline na C-peptide bitewe n’uko ubudahangarwa bw’umubiri bwibasiye uturemangingo twa beta dukora insuline. Ku rundi ruhande, abantu barwaye diyabete yo mu bwoko bwa 2 bashobora kugira urugero rusanzwe cyangwa ruri hejuru rwa C-peptide kubera ko imibiri yabo ikora insuline ariko ikaba idashobora guhangana n’ingaruka zayo. Gukurikirana urugero rwa C-peptide mu barwayi, nk’abakorerwa ishinya ry’uturemangingo, bishobora gutanga ubumenyi bw’ingirakamaro ku ntsinzi y’ubuvuzi.

Ubushakashatsi bwanasesenguye ingaruka zishobora guterwa na C-peptide ku mubiri w’umuntu. Ubushakashatsi bumwe bwerekana ko C-peptide ishobora kugira ubushobozi bwo kurwanya ububyimbirwe bushobora gufasha kugabanya ingorane ziterwa na diyabete, nko kwangirika kw’imitsi n’impyiko. Nubwo C-peptide ubwayo itagira ingaruka ku rugero rwa glucose mu maraso, ikora nk'ikimenyetso cy’agaciro mu gucunga diyabete no guhuza gahunda zo kuvura n’ibyo umuntu akeneye. Niba ushaka gusesengura cyane diyabete, komeza umenye byinshi kuriamakuru y'ubucuruzibifitanye isano n'ubuvuzi n'iterambere ry'ubuvuzi bishobora gutanga ubumenyi bw'ingirakamaro ku banyamwuga ndetse n'abarwayi.
