Iyo Virus, Kwamunogara Izvo, Simba Rako Rokuzvidzivirira, uye DNA Yako Inobatanidzwa
Hapana anoziva zvinonyatsokonzera multiple sclerosis (MS). Izvozvo zvichiti, zvinhu zvina zvakakosha zvakabuda kuedza kutsanangura kuti nei vamwe vanhu vachikudziridza MS uye vamwe havaiti. Kunyange zvazvo chimwe nechimwe chezvinhu izvi chinogona kutsanangura chikamu cheSMS puzzle, hapana anogona kutsanangura zvose. Izvi zvinokonzera zvina zvinosanganisira:
- the immune system
- nzvimbo
- zvirwere zvinotapukira
- genetics
Immune System uye MS
Kunyange pasina munhu anoziva chikonzero nei, vazhinji vanotsvakurudza vanobvumirana kuti MS inokonzerwa nehutachiona hunorwisa muviri. Kunyanya, masero ezvirwere zvemasimba anokonzera masero muuropi nemumutsipa wepelinha , achikuvadza kunze kweheati (myelin) yemitsipa. Kukanganisa kunokonzera kuti mishonga iyoyo inoshanda zvakadini-iyo inokonzera zviratidzo zveSMS nekuremara. Zvirwere zvinoshandiswa nehutano zvinoshanda nekushandisa nzira dzakasiyana-siyana kudzivirira muviri wemuviri wezvirwere kuti urege kurwisa hurongwa hwenheyo.
Environment uye MS
Vanhu mune dzimwe nzvimbo uye nzvimbo dzine njodzi yakakura yeMS kune dzimwe. Nokudzidza vanhu vanobva kune imwe nzvimbo kuenda kune imwe, vatsvakurudzi vakadzidza kuti mumwe munhu anotengesa kuchinja kubva panzvimbo.
Ichokwadi, MS inowedzera kune dzimwe nzvimbo dziri kure neEricator. Vakawanda vanotsvakurudza vanodavira kuti vitamini D inogona kubatanidzwa mukutsanangura ichi chiitiko. Vitamini D inogadzirwa nemuviri kana ganda rinosvikirwa nezuva.
Munzvimbo dziri kure neEquator, mhepo inosvina kunze kwemazuva ezuva anoita kuti utachiona D hugadzike mumuviri.
Kutsvakurudza kutsva kunoratidza kuti mazinga epamusoro e vitamini D anogona kudzivirira munhu kubva mukurudzira MS, uye kunyange kudzivirira munhu anenge atova neWS kubva pakudzoka zvakare.
Kune dzimwe mamiriro ezvinhu ezvezvakatipoteredza izvo masayendisiti akacherechedza sezvingave zvinokonzera MS zvinosanganisira:
- kusvuta
- imwe yakadyiwa yemunyu
- kuneta (kunyanya mukuyaruka)
Zvirwere uye MS
Zvimwe mavharusi anozivikanwa kuti anokonzera kukanganisa kwakafanana neakaonekwa muMS. Vamwe vatsvakurudzi vanotenda kuti zvirwere zvinogona kuita kuti maitiro ezvirwere zvemusununguko arwise masero. Chaizvoizvo, hutachiona (kana mabhakitiriya) anokonzera utachiona hwekutanga "hunotarisa" sewesero resimbi. Mune maitiro ezvirwere mumuviri anotanga T-seli kuti varwise utachiona. Izvozvo T-masero anoramba ari mumuviri wako mushure mokunge utachiona hwaenda uye hukavhiringidzika pavano "ona" masero esero, achizvifungidzira kuti uri muvengi. Chigumisiro ndechokuti maune immune system anorwisa hurongwa hwako hwemagetsi.
Rimwe girasi rinowanzobatanidzwa neMS ndiyo Epstein-Barr virus-iyo inokonzera "mono." Iyi ndiyo hutachiona hunowanzosangana nehuwandu hwevanhu pane imwe nguva muupenyu hwavo. Kutanga kufanana nehutachiona kunogona kuita basa mukuvandudza kweSMS, asi nyanzvi hazvizivikanwe panguva ino.
Panguva ino, hapana chirwere chinotapukira (utachiona, mabhakitiriya, kana fungus) yakawanikwa kujekesa kukonzera MS.
DNA yako ne MS
Vanotsvakurudza vanodavira kuti mamwe masangano ekugadzirwa kwemagenho anowedzera mikana yemunhu anovhura MS. Kutaura zvazviri, masayendisiti ave akaisa mazita ejena anoonekwa achibatanidza neMS, akawanda ari pedyo nemagenene anowanikwa nemunhu wesimba remuviri.
Mukuwedzera pakuvandudza MS, zvinokwanisika kuti mazamu ako anogonawo kufanidzira rudzi rweMS iwe une, chirwere chako chakanyanya sei, uye iwe unopindura zvakanaka kumishonga ekurapa zvirwere zve MS.
Izvi zvinotaurwa, zvakakosha kunzwisisa kuti MS haisi "chirwere chetachiona" -kucherechedza kuti hapana gara rimwe chete rakagara nhaka kana sarudzo dzakawanikwa dzinoratidza kuti munhu achawana MS. Pane kudaro, zvinoratidzika kuti majini ndeimwe chinhu, pakati pevakawanda, izvo zvinogadzirisa njodzi yemunhu yeMS.
Mikana yako yekuvandudza MS inowedzera kana uine hama na MS-imwe nyanzvi iyo genetics inoita basa mukuvandudzirwa kweSMS.
Mikana yako yekuvandudza MS inenge:
- 1 mu 750 kana usina hama dze MS
- 1 muna 50 kana uine mubereki ane MS
- 1 mu20 kana iwe uine mukoma wako ane MS
- 1 muna 4 kana iwe wakafanana nemapatya ane MS
