Ukungondleki noma Ukungabi namsoco isimo esidalwa ukudla okungenazo izakhimzimba ezanele noma okunezakhamzimba eziningi zize zibange izifo. Izakhamzimba ezibalwayo zingabandakanya: amakhalori, amaprotheni, isitashi, amavithamini noma amaminerali. Kuvamise ukusetshenziselwa ukubiza ukudla okungenazo izakhamzimba ezanele uma amakhalori, iphrotheni noma izakhamzimba ezincane ezibalulekile engenele; kodwa, kuphinde kubandakanye ukudla okunezakhamzimba eziningi ngokweqile.Uma ukushoda kwezakhamzimba kwenzeka ngesikhathi ukhulelwe noma ngaphambi kweminyaka emibili yobudala kungase kudale izinkinga zesikhathi eside ekukhuleni ngokomzimba nangokwengqondo. Ukungabi nawo kakhulu umsoco, okwaziwa ngendlala, kungaba nezimpawu ezibandakanya: ukuba mfishane, umzimba owondile, amazinga aphansi kakhulu omdlandla, kanye nokuvuvukala kwemilenze kanye nesisu.Abantu futhi bavamise ukuthola izifo kanti futhi bajwayele ukugodola. Izimpawu zokungabi nazo izakhamzimba ezincane ezibalulekile kuya ngokuthi yisiphi isakhamzimba esishodayo. Ukungabi nawo umsoco imvamisa kudalwa ukungatholi ukudla okusezingeni eliphezulu esingakudla. Lokhu kuvamise ukudalwa amanani aphezulu okudla kanye nenhlupheko. Uma ungazange uncelise ubisi lwebele kungase kube nomthelela, ngoba eziningi zezifo ezithelelanayo ezifana: ne-gastroenteritis (ukuvuvukala kwesisu namathumbu), inyumoniya, umalaleveva kanye nesimungumungwana okukwenyusa isidingo somsoco wezakhamzimba. Kukhona izinhlobo ezimbili zokungabi namsoco: ukungabi namsoco wephrotheni yamandla kanye nokungabi namsoco ekudleni esikudlayo. Ukungabi namsoco wephrotheni yamandla kunezindlela ezimbili ezimbi kakhulu: i-marasmus (ukuntuleka kwephrotheni nekhalori) kanye nekhwashu (ukuntuleka kwephrotheni).
