Isikhumba esimnyama ngokungaqhelekanga okanye ukukhanya

Ulusu olumnyama ngokungaqhelekanga okanye olukhanyayo lulusu olujike lwaba mnyama okanye lube lula kunesiqhelo.

Ulusu oluqhelekileyo luqukethe iiseli ezibizwa ngokuba yimelanocytes. Ezi seli zivelisa i-melanin, into enika ulusu umbala wayo.

Isikhumba esine-melanin eninzi sibizwa ngokuba sisikhumba esi-hyperpigmented.

Ulusu olune-melanin encinci lubizwa ngokuba yi-hypopigmented. Ulusu olungenayo i-melanin konke kuthiwa lubonakalisiwe.

Iindawo zolusu eziluhlaza ngenxa ye-melanin encinci okanye ii-melanocytes ezingasebenziyo. Iindawo ezimnyama zolusu (okanye indawo ethambisa ngokulula) yenzeka xa une-melanin engaphezulu okanye ii-melanocytes ezingaphezulu.

Ukuqaqamba kolusu ngamanye amaxesha kunokuphosakela njenge-suntan. Ukujika kombala kuhlala kukhula kancinci, ukuqala kwiingqiniba, amaqhina, kunye namadolo nokusasazeka ukusuka apho. Ukwenza ibronzing kunokubonwa kwangaphantsi kweenyawo kunye neentende zezandla. Umbala wobhedu unokuhluka ukusuka ekukhanyeni uye kubumnyama (kubantu abanesikhumba esihle) ngenqanaba lobumnyama ngenxa yesizathu esingunobangela.

Oonobangela bokubengezela kubandakanya:

• Ukudumba kolusu (i-hyperpigmentation yasemva kokuvuvukala)
• Ukusetyenziswa kwamachiza athile (anje nge-minocycline, iichemotherapies ezithile zomhlaza kunye neepilisi zolawulo lokuzalwa)
• Izifo zenkqubo yehormone ezinje ngesifo iAddison

• Ezinye izifo ezithathelwanayo (ezifana ne-tinea versicolor)
• Pityriasis alba
• Vitiligo
• Amayeza athile
• Imeko yesikhumba ebizwa ngokuba yi-idiopathic guttate hypomelanosis kwiindawo ezivezwe lilanga ezifana neengalo

Ulusu olumnyama ngokungaqhelekanga lungaqhubeka nasemva konyango.

Fowunela umboneleli wakho wezempilo ukuze abekho xa:

• Ukutshintsha kwesikhumba okubangela inkxalabo ebalulekileyo
• Ukuqhubela phambili, ubumnyama obungachazwanga okanye ukukhanya kwesikhumba
• Nasiphi na isikhumba esibuhlungu okanye isilonda esiguqula ubume, ubungakanani, okanye umbala kunokuba luphawu lomhlaza wolusu

Uvavanyo olunokwenziwa lunokubandakanya:

• Uvavanyo lokukhuthaza iadrenocorticotrophin
• Ulusu lwe-biopsy
• Izifundo zomsebenzi we-thyroid
• Uvavanyo lwesibane somthi

Umboneleli wakho unokucebisa iikhrimu, ioyile, uqhaqho, okanye ukufotowa, ngokuxhomekeke kuhlobo lwesikhumba onaso. Izithambisi ezibomvu zinokunceda ekukhanyiseni iindawo ezimnyama zolusu.
