Intoleran\u021ba la lactoz\u0103 este un semn al incapacit\u0103\u021bii de a digera zah\u0103rul (lactoza) care este prezent în lapte. Intoleran\u021ba la lactoz\u0103, cunoscut\u0103 \u0219i ca absorb\u021bia proast\u0103 a lactozei, cauzeaz\u0103 diareea, gaze \u0219i balonarea dup\u0103 consumarea produselor din lapte.<\/p>\n

Deficien\u021ba de lactaz\u0103 (enzima produs\u0103 de intestinul sub\u021bire) este cauza intoleran\u021bei la lactoz\u0103. Deficien\u021ba de lactaz\u0103 duce la apari\u021bia simptomelor dup\u0103 consumarea produselor din lapte. Boala nu este periculoas\u0103, dar simptomele pot provoca disconfort.<\/p>\n

În cele mai multe cazuri, boala poate fi administrat\u0103 eficient f\u0103r\u0103 a renun\u021ba la produsele din lapte.<\/p>\n

 <\/p>\n

Simptome<\/h2>\n

Simptomele intoleran\u021bei la lactoz\u0103 includ:<\/p>\n

Diaree<\/p>\n

Grea\u021b\u0103 \u0219i vom\u0103<\/p>\n

Balonare<\/p>\n

Gaze<\/p>\n

Crampe abdominale<\/p>\n

 <\/p>\n

Cauze<\/h2>\n

Intoleran\u021ba la lactoz\u0103 este rezultatul produc\u021biei insuficiente de enzime lactaz\u0103 de c\u0103tre intestinul sub\u021bire. Lactaza este folosit\u0103 pentru a digera zah\u0103rul din lapte (lactaz\u0103) prin transformarea acestuia în zaharuri simple (glucoz\u0103 \u0219i galactoz\u0103)<\/p>\n

Deficien\u021ba de lactaz\u0103 provoac\u0103 mutarea lactozei din alimente în colon unde lactoza nedigerat\u0103 interac\u021bioneaz\u0103 cu bacteriile normale provocând simptomele de intoleran\u021b\u0103 la lactoz\u0103.<\/p>\n

Intoleran\u021ba la lactoz\u0103 poate fi clasificat\u0103 în trei categorii. Factorii diferi\u021bi cauzeaz\u0103 deficien\u021ba de lactaz\u0103 din fiecare categorie.<\/p>\n

 <\/p>\n

Intoleran\u021ba primar\u0103 la lactoz\u0103<\/p>\n

Intoleran\u021ba primar\u0103 la lactoz\u0103 este cel mai întâlnit tip. Oamenii cu intoleran\u021b\u0103 primar\u0103 la lactoz\u0103 produc suficient\u0103 lactaz\u0103 la începutul vie\u021bii. Totu\u0219i, produc\u021bia de lactaz\u0103 descre\u0219te odat\u0103 cu vârsta, \u0219i asta poate duce la intoleran\u021ba primar\u0103 la lactoz\u0103 unde produc\u021bia de lactaz\u0103 scade. Ca \u0219i rezultat, produsele din lapte devin din ce în ce mai greu de digerat la maturitate.<\/p>\n

Intoleran\u021ba primar\u0103 de lactoz\u0103 este predeterminat\u0103 genetic \u0219i în cele mai multe cazuri apare la oamenii din Africa, Asia sau Spania.<\/p>\n

 <\/p>\n

Intoleran\u021ba secundar\u0103 la lactoz\u0103<\/p>\n

Intoleran\u021ba secundar\u0103 la lactoz\u0103 este rezultatul produc\u021biei sc\u0103zute de lactaz\u0103 dup\u0103 boal\u0103, opera\u021bie sau r\u0103nirea care implic\u0103 intestinul sub\u021bire. Principalele boli asociate cu acest tip de intoleran\u021b\u0103 la lactoz\u0103 sunt supracre\u0219terea bacterian\u0103, boala celiac\u0103 \u0219i boala Crohn. Tratamentul bolii de baz\u0103 poate ameliora simptomele intoleran\u021bei la lactoz\u0103 \u0219i poate reda nivelul de lactaz\u0103.<\/p>\n

Intoleran\u021ba la lactoz\u0103 congenital\u0103 sau de dezvoltare<\/p>\n

Acest tip de intoleran\u021b\u0103 la lactoz\u0103 este mo\u0219tenit\u0103 de la p\u0103rin\u021bi printr-un model autozomal recesiv, care provoac\u0103 absen\u021ba complet\u0103 a activit\u0103\u021bii de lactaz\u0103.<\/p>\n

 <\/p>\n

Factori de risc<\/h2>\n

Factorii de risc pentru intoleran\u021ba de lactoz\u0103 includ:<\/p>\n

Vârsta: Intoleran\u021ba la lactoz\u0103 apare la maturitate.<\/p>\n

Etnicitate: cele mai multe cazuri de intoleran\u021b\u0103 la lactoz\u0103 sunt înregistrate la oamenii din Africa, Asia, Spania.<\/p>\n

Na\u0219terea prematur\u0103: copiii prematuri au un risc crescut de intoleran\u021b\u0103 la lactoz\u0103 din cauza nivelul sc\u0103zut de lactaz\u0103. Nivelul sc\u0103zut de lactaz\u0103 este rezultatul celulelor subdezvoltate de lactaz\u0103 din intestinul sub\u021bire.<\/p>\n

Bolile care afecteaz\u0103 intestinul sub\u021bire: Supracre\u0219terea bacterian\u0103, boala celiac\u0103 \u0219i boala Crohn poate duce la intoleran\u021ba la lactoz\u0103.<\/p>\n

Tratamentele pentru cancer: Terapia cu radia\u021bii pentru cancerul abdominal sau complica\u021biile intestinale de la chimioterapie pot provoca intoleran\u021ba la lactoz\u0103.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-70757","disease","type-disease","status-publish","hentry"],"yoast_head":"\nIntoleran\u021b\u0103 la lactoz\u0103 - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"ro_RO\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Intoleran\u021b\u0103 la lactoz\u0103 - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Intoleran\u021ba la lactoz\u0103 este un semn al incapacit\u0103\u021bii de a digera zah\u0103rul (lactoza) care este prezent în lapte.
