Uma ungumama ozoba nomntwana, cishe usuvele uqaphele izinguquko eziningi emzimbeni wakho. Phakathi kwalezi, cishe usuqaphele umugqa omnyama, oqondile owela phakathi kwesisu sakho, ikakhulukazi kusuka enkabeni yakho. Abanye abantu bakubiza nangokuthi 'umugqa wokukhulelwa'. Kujwayelekile ukuthi abanye omama bazizwe besaba futhi befuna ukwazi lapho bebona lokhu. Imibuzo efana nokuthi "Kuyini lokhu? Ingabe lokhu kuyingozi? Ingabe kuzothinta ingane?" kumele ukuthi ifike engqondweni yakho. Ngakho ungakhathazeki, namuhla sizoxoxa ngalo mugqa, owaziwa ngokwezokwelapha ngokuthi 'i-Linea Nigra'.
Kalula nje, iyini le Linea Nigra?
I-Linea Nigra igama lesiLatini elisho "umugqa omnyama." Lona umugqa omnyama oqondile ovela esikhumbeni sesisu sakho ngesikhathi sokukhulelwa. Lo mugqa uvame ukuhamba kusukela enkabeni yesisu sakho uye esiswini sakho esingezansi. Kodwa-ke, kwabanye abantu, ungasuka enkabeni yesisu sakho uye esifubeni sakho.
Njengoba ukukhulelwa kwakho kuqhubeka, okusho ukuthi ingane yakho ikhula, lo mugqa uzoba mnyama futhi ubonakale kakhulu. Futhi, abantu abanesikhumba esimnyama bangase bawubone kahle lo mugqa kunalabo abanesikhumba esikhanyayo. Lokhu kungenxa yokuthi inani le-pigment elinikeza isikhumba umbala waso liyakhula.
Into ebalulekile ukuthi lokhu kujwayelekile futhi akunangozi. Ngeke kukulimaze wena noma ingane yakho.
Liphuma nini leli langa? Ingabe belilokhu likhona?
Ungase umangale ukuzwa lokhu, kodwa lo mugqa ubulokhu usesiswini sakho. Kodwa ngaphambi kokukhulelwa, ubizwa ngokuthi 'uLinea Alba', okusho ukuthi "umugqa omhlophe". Ngaleso sikhathi, ukhanya kakhulu kangangokuthi amehlo ethu awakwazi nokuwubona.
Ngesikhathi sokukhulelwa, 'umugqa omhlophe' uba mnyama kancane kancane bese ubonakala 'njengomugqa omnyama' noma 'uLinea Nigra' ngenxa yezinguquko zamahomoni emzimbeni. Kubantu abaningi, lo mugqa uvame ukubonakala ngokucacile ku-trimester yesibili yokukhulelwa, cishe emavikini angama-20 okukhulelwa.
Ingabe le Linea Nigra iyenzeka kubo bonke abesifazane abakhulelwe?
Lo mugqa uvela cishe ku-80% wabesifazane abakhulelwe, noma cishe ku-8 kwabayishumi. Kodwa njengoba ngishilo ngaphambili, ukuthi ubonakala ngokucacile kangakanani kuncike esikhumbeni sakho.
Cabanga ngakho, isikhumba sethu sinombala we-pigment ebizwa ngokuthi i-Melanin. Abantu abanesikhumba esimnyama ngokwemvelo banalo mbala omningi emizimbeni yabo. Ngakho-ke, lapho ukukhiqizwa kwe-melanin kwanda ngenxa yethonya lama-hormone ngesikhathi sokukhulelwa, i-Linea Nigra yabo iba sobala kakhulu futhi ibe mnyama. Kubantu abanesikhumba esikhanyayo, kungase kungabi sobala kangako, ngezinye izikhathi kungase kubonakale kunsundu kancane.
| Izinto okudingeka uzazi nge-Linea Nigra | Incazelo |
|---|---|
| Kuyini lokhu? | Umugqa omnyama ogeleza phakathi nesisu ngesikhathi sokukhulelwa. |
| Izovela nini? | Ngokuvamile ku-trimester yesibili (ngemuva kwamasonto angama-20). |
| Iyini imbangela? | Ukukhiqizwa okwandisiwe kwe-pigment yesikhumba (i-melanin) ngenxa yokwanda kwama-hormone okukhulelwa. |
| Ingabe lokhu kuyingozi? | Cha, akulona neze ingozi. Lesi yisimo esijwayelekile. |
| Ulahlekile? | Yebo, kancane kancane iyanyamalala ngemva kwamasonto noma izinyanga ezimbalwa ngemva kokubeletha umntwana. |
Kungani lo mugqa uvela ngesikhathi sokukhulelwa? Iyini isizathu sesayensi?
Nakuba imbangela eqondile yalokhu ingakaziwa ngokuphelele, odokotela bakholelwa ukuthi imbangela eyinhloko izinguquko ezinkulu emazingeni ama-hormone ezenzeka emzimbeni ngesikhathi sokukhulelwa.
Kalula nje, i-placenta ikhiqiza i-hormone ebalulekile ekukhuleni komntwana. Le hormone ivuselela amangqamuzana akhiqiza umbala obizwa ngokuthi 'i-melanin', onikeza umbala wesikhumba sethu. Lokhu kwandisa ukukhiqizwa kwe-melanin, okubangela ukuba ezinye izindawo zesikhumba zibe mnyama.
Njengoba nje uthola amabala amnyama ebusweni bakho (abizwa ngokuthi i-melasma) kanye nesikhumba esimnyama esizungeze amakhwapha akho, imbobo, kanye nezingono ngesikhathi sokukhulelwa, noLinea Nigra uba njalo. Konke lokhu kungenxa yenqubo efanayo yamahomoni.
Kodwa kungani lo mzimba okhethekile ?Akukacaci ukuthi amabala kuphela azoba mnyama. Ogogo bethu babevame ukubheka lo mugqa bese bebikezela ubulili bomntwana, kodwa akukho sisekelo sesayensi salokho, akunjalo? Ngakho-ke ningazikholelwa izindaba ezinjalo.
Ayikho indlela yokuvimbela noma yokuqeda lokhu?
Lena inkinga ebhekene nomama abaningi. Kodwa iqiniso liwukuthi, awukwazi ukuvimbela i-Linea Nigra ukuthi ivele. Ngoba ihlobene ngokuphelele nenqubo yamahomoni eyenzeka emzimbeni wakho.
