stdClass Object ( [id] => 1207488 [title] => Muškarac završio u bolnici zbog pretjeranog unosa dodataka prehrani, jedan vitamin ga je skoro koštao života [alias] => muskarac-zavrsio-u-bolnici-zbog-pretjeranog-unosa-dodataka-prehrani-jedan-vitamin-ga-je-skoro-kostao-zivota [catid] => 264 [published] => 1 [introtext] => [fulltext] =>

Priča o Britancu koji se je predozirao vitaminom D upozoravajuća je priča za ljude koji razmišljaju o dodavanju dodataka prehrani u svoje živote, piše CNN.

Nakon posjeta privatnom nutricionistu, muškarac je počeo uzimati više od 20 dodataka prehrani bez recepta svaki dan, uključujući 50.000 međunarodnih jedinica (IU) vitamina D tri puta dnevno. To je doza stotinama puta veća od standardnih prehrambenih preporuka.

U roku od mjesec dana, muškarac je počeo patiti od mučnine, bolova u trbuhu, proljeva i opetovanih napadaja povraćanja, zajedno s grčevima u nogama i zujanjem u ušima.

Čovjek, čije ime nije objavljeno, čuo je za suplemente iz radio talk showa i nakon toga je kontaktirao nutricionista u emisiji, rekao je dr. Alamin Alkundi, koautor izvješća i endokrinolog u bolnici William Harvey u East Kentu u UK, koji je liječio čovjeka.

-Registracija od strane regulatora nije obavezna za nutricioniste u Ujedinjenom Kraljevstvu i njihova titula nije zaštićena, tako da svatko može raditi kao nutricionist, rekao je Alkundi u e-mailu.

Za razliku od vitamina topivih u vodi, koje tijelo može lako eliminirati, vitamin D pohranjuje se u jetri i masnim stanicama tijela dok ne zatrebaju. Konzumiranje znatno veće od dnevne preporučene doze može povećati toksične razine.

Muškarac u studiji slučaja uzimao je dnevnu dozu od 150.000 IU vitamina D, što je bilo "375 puta više od preporučene količine", rekao je Alkundi. Nacionalna zdravstvena služba Ujedinjenog Kraljevstva obično preporučuje 400 IU vitamina D dnevno za djecu stariju od 1 godine i odrasle.

Čovjek je prestao uzimati dodatke prehrani kad su mu se pojavili simptomi, ali stanje mu se nije popravilo. Do trenutka kada je dva mjeseca kasnije upućen u bolnicu, izgubio je skoro 13 kilograma i bubrezi su mu bili propadali. Testovi su pokazali da se predozirao vitaminom D, upao je u stanje koje se naziva hipervitaminoza D.

Organizmu je potreban vitamin D. Njegov glavni posao je da pomaže tijelu apsorbirati kalcij iz crijeva – tijelo ne može apsorbirati kalcij bez vitamina D. On također igra ulogu u imunitetu, aktivnosti moždanih stanica i funkciji mišića.

Američki instituti za zdravstvo preporučaju 600 IU vitamina D dnevno za odrasle do 69 godina starosti. Za starije od toga, preporučena doza je 800 IU vitamina svaki dan. Za novorođenčad, djecu i tinejdžere, Američka akademija za pedijatriju nedavno je povećala preporuku na 400 IU dnevno.

Studija iz 2017. pokazala je da tri posto Amerikanaca uzima više od gornje granice od 4.000 IU dnevno za odrasle, što povećava rizik od predoziranja. Oko 18 posto uzima više od 1.000 IU vitamina D dnevno.

Previše vitamina D u krvi dovodi do hiperkalcemije, odnosno povećane razine kalcija u krvi. Muškarcu u studiji dijagnosticirana je upravo hiperkalcemija, koja može oslabiti kosti, stvoriti bubrežne kamence i poremetiti rad mozga i srca.

Muškarac je u bolnici ostao osam dana, gdje su mu dani lijekovi za spuštanje razine kalcija u krvi. Oni su došli do gotovo normalnih razina tek dva mjeseca kasnije.

Dok se razina vitamina D u muškarčevom organizmu značajno smanjila, ona je ipak ostala visoka, kaže dr. Alkundi.

-Osmislili smo plan da periodično provjeravamo oba paramentra kako bismo pratili spuštanje razina na normalne. U kontaktu smo s pacijentom, kaže nam da se osjeća mnogo bolje, ali još uvijek nije potpuno zdrav,” dodaje Alkundi.

Znakovi predoziranja vitaminom D uključuju pospanost, zbunjenost, letargiju i depresiju, a može doći i do problema s vidom i sluhom. U ozbiljnijim slučajevima predoziranje može dovesti do otupjelosti ili čak kome. I srčani organ može biti pogođen jer dolazi do porasta krvnog tlaka i srce počinje nekontrolirano lupati. U teškim slučajevima dolazi do zatajenja bubrega.

Tijelo generira dovoljne doze vitamina D preko izloženosti suncu. Boravak na otvorenom u kupaćem kostimu na tek 10 ili 15 minuta dnevno ljeti je dovoljno za proizvodnju 10.000 do 20.000 IU vitamina D u organizmima odraslih ljudi sa svjetlijom kožom.

Ipak, boravak na jakom podnevnom suncu ne preporuča se zbog rizika od raka kože, objavio je CNN.

Priča o Britancu koji se je predozirao vitaminom D upozoravajuća je priča za ljude koji razmišljaju o dodavanju dodataka prehrani u svoje živote, piše CNN.

Nakon posjeta privatnom nutricionistu, muškarac je počeo uzimati više od 20 dodataka prehrani bez recepta svaki dan, uključujući 50.000 međunarodnih jedinica (IU) vitamina D tri puta dnevno. To je doza stotinama puta veća od standardnih prehrambenih preporuka.

U roku od mjesec dana, muškarac je počeo patiti od mučnine, bolova u trbuhu, proljeva i opetovanih napadaja povraćanja, zajedno s grčevima u nogama i zujanjem u ušima.

Čovjek, čije ime nije objavljeno, čuo je za suplemente iz radio talk showa i nakon toga je kontaktirao nutricionista u emisiji, rekao je dr. Alamin Alkundi, koautor izvješća i endokrinolog u bolnici William Harvey u East Kentu u UK, koji je liječio čovjeka.

-Registracija od strane regulatora nije obavezna za nutricioniste u Ujedinjenom Kraljevstvu i njihova titula nije zaštićena, tako da svatko može raditi kao nutricionist, rekao je Alkundi u e-mailu.

Za razliku od vitamina topivih u vodi, koje tijelo može lako eliminirati, vitamin D pohranjuje se u jetri i masnim stanicama tijela dok ne zatrebaju. Konzumiranje znatno veće od dnevne preporučene doze može povećati toksične razine.

Muškarac u studiji slučaja uzimao je dnevnu dozu od 150.000 IU vitamina D, što je bilo "375 puta više od preporučene količine", rekao je Alkundi. Nacionalna zdravstvena služba Ujedinjenog Kraljevstva obično preporučuje 400 IU vitamina D dnevno za djecu stariju od 1 godine i odrasle.

Čovjek je prestao uzimati dodatke prehrani kad su mu se pojavili simptomi, ali stanje mu se nije popravilo. Do trenutka kada je dva mjeseca kasnije upućen u bolnicu, izgubio je skoro 13 kilograma i bubrezi su mu bili propadali. Testovi su pokazali da se predozirao vitaminom D, upao je u stanje koje se naziva hipervitaminoza D.

Organizmu je potreban vitamin D. Njegov glavni posao je da pomaže tijelu apsorbirati kalcij iz crijeva – tijelo ne može apsorbirati kalcij bez vitamina D. On također igra ulogu u imunitetu, aktivnosti moždanih stanica i funkciji mišića.

Američki instituti za zdravstvo preporučaju 600 IU vitamina D dnevno za odrasle do 69 godina starosti. Za starije od toga, preporučena doza je 800 IU vitamina svaki dan. Za novorođenčad, djecu i tinejdžere, Američka akademija za pedijatriju nedavno je povećala preporuku na 400 IU dnevno.

Studija iz 2017. pokazala je da tri posto Amerikanaca uzima više od gornje granice od 4.000 IU dnevno za odrasle, što povećava rizik od predoziranja. Oko 18 posto uzima više od 1.000 IU vitamina D dnevno.

Previše vitamina D u krvi dovodi do hiperkalcemije, odnosno povećane razine kalcija u krvi. Muškarcu u studiji dijagnosticirana je upravo hiperkalcemija, koja može oslabiti kosti, stvoriti bubrežne kamence i poremetiti rad mozga i srca.

Muškarac je u bolnici ostao osam dana, gdje su mu dani lijekovi za spuštanje razine kalcija u krvi. Oni su došli do gotovo normalnih razina tek dva mjeseca kasnije.

Dok se razina vitamina D u muškarčevom organizmu značajno smanjila, ona je ipak ostala visoka, kaže dr. Alkundi.

-Osmislili smo plan da periodično provjeravamo oba paramentra kako bismo pratili spuštanje razina na normalne. U kontaktu smo s pacijentom, kaže nam da se osjeća mnogo bolje, ali još uvijek nije potpuno zdrav,” dodaje Alkundi.

Znakovi predoziranja vitaminom D uključuju pospanost, zbunjenost, letargiju i depresiju, a može doći i do problema s vidom i sluhom. U ozbiljnijim slučajevima predoziranje može dovesti do otupjelosti ili čak kome. I srčani organ može biti pogođen jer dolazi do porasta krvnog tlaka i srce počinje nekontrolirano lupati. U teškim slučajevima dolazi do zatajenja bubrega.

Tijelo generira dovoljne doze vitamina D preko izloženosti suncu. Boravak na otvorenom u kupaćem kostimu na tek 10 ili 15 minuta dnevno ljeti je dovoljno za proizvodnju 10.000 do 20.000 IU vitamina D u organizmima odraslih ljudi sa svjetlijom kožom.

Ipak, boravak na jakom podnevnom suncu ne preporuča se zbog rizika od raka kože, objavio je CNN.
