Environmental enteropathy ( EE ma ọ bụ tropical enteropathy ma ọ bụ gburugburu ebe obibi n'adighi nke ọma ) bụ nsogbu nke mbufụt nke eriri afọ na-adịghị ala ala.

Environmental enteropathy (EE) na-emetụtakarị ụmụaka bi na mba ndị nwere obere ego na nke etiti (LMIC). [17] Achọpụtara ụmụaka ndị bi na mba ndị a ka ha nwere nje nje metụtara EE na sistemu ha n'ime oge niile ha bụ nwata.

[18] [19] Ọdịiche dị otú ahụ na-etolite mgbe ọkara nke mbụ nke ndụ na-adịghị adị na ụmụ ọhụrụ. [18]

Kemgbe ụwa, environmental enteropathy gburugburu ebe obibi agbasawo na LMICs. [19] Nkesa ala dum nke enteropathy gburugburu ebe obibi egosila mmụba nke ọnọdụ na mpaghara ndị dị otú ahụ nke adịghị ọcha na ịdị ọcha. [17] E bu ụzọ kọwaa EE na nyocha sitere n'afọ 1960-70 nke emere na Asia, Africa, subcontinent India, na Central America, n'oge a chọpụtara na akara EE dị elu n'etiti ndị okenye na ụmụaka nwere ahụike. [20] A na-akpọkarị ọmụmụ ihe sitere n'afọ 1971 na-esote ndị ọrụ afọ ofufo US Peace Corps dị ka ihe ọmụmụ mbụ gosipụtara ikike iji nweta na ịgbake na EE dịka gburugburu ebe obibi. [19] Ndị sonyere na-enweta ihe mgbaàmà nke ọrịa enteric na-adịghị ala ala n'oge na obere oge ka ha lọtachara na ntinye ha na mba ndị na-akpata obere ego na etiti.

[19] Nsonaazụ ndị a na-eduga na aro nke gburugburu ebe obibi bụ ihe kpatara EE, na ọmụmụ ihe mechara na Zambia nwere ike nweta nkwubi okwu yiri nke ahụ. [19] Ka ọ na-erule mmalite mgbe afọ 1990s, a chọpụtara na enteropathy gburugburu ebe obibi bụ nsogbu zuru ebe niile na-emetụta ụmụ ọhụrụ na ụmụaka.
