Chirwere chevafambisi vengarava avo vaingodya chikafu chemumagaba panguva yekuyambuka kwavo mugungwa, chirwere cheBeriberi chakabatana nekushomeka kwevhitamini B1. Inokosha kumuviri, kushomeka uku ndiko kwakatangira kusagadzikana kwetsinga uye nemoyo, dzimwe nguva isingadzokere shure. Kuwedzera kwaro kwekutanga kuburikidza nechikafu uye kurapwa kunoitendera kuti irapwe. 

Chirwere chekushomeka chinozivikanwa kubvira kuMabvazuva kubva muzana ramakore regumi nemanomwe muzvidzidzo zveAsia vaingodya mupunga chena chete, zvakaonekwawo kune vafambisi vengarava vaingodya chikafu chemumagaba panguva yerwendo rwavo rwakareba mugungwa vasati vanzwisisa kuti kudzivirira kwavo kwakapfuura nekudya kwakapfumisa mavitamini, kunyanya vhitamini B1. Naizvozvo zita rekuti Beriberi revhitamini B. 

Muviri wemunhu zvechokwadi haukwanise kugadzira vhitamini iyi uye inoda mipiro yakakwana yekudya kuti metabolism ishande nenzira yakaenzana uye inoshanda.

Iyi vhitamini zvakadaro iripo mune zvakawanda zvigadzirwa zvechikafu chikafu senge zviyo, nyama, nzungu, nyemba kana mbatatisi.

Kushomeka kwayo kuchiri kunetsekana nanhasi kunyanya nyika dzichiri kusimukira dzinotambura nekushaya kudya zvinovaka muviri uye dzinofarira kudya kunobva pakunatswa makabhohaidhiretsi (mupunga muchena, shuga chena, sitachi chena…). 

Asi zvinogona zvakare kuitika mukudya zvisina kuenzana senge vegan dhayeti, kana mune zviitiko zveanorexia nervosa mune vechidiki vakuru. Zvimwe zvirwere zvinogona zvakare kuve chikonzero chekushomeka kwevhitamini B1 senge hyperthyroidism, kuwedzerwa kwemudumbu kwenguva refu senge panguva yechirwere chisingaperi kana kutadza kwechiropa. Inowanikwa chete muvarwere vanorwara nedoro kupindwa muropa uye cirrhosis yechiropa.

Vitamin B1 kushomeka kunotungamira mukudzikira kwehutachiona hwemitsipa (neuropathy), yemamwe matunhu ehuropi (thalamus, cerebellum, nezvimwewo) uye inoderedza kutenderera kwehuropi nekuwedzera kuramba kweiyo cerebral midziyo yeropa kutenderera kweropa. Inokanganisawo moyo, unowedzera uye hauite mushe pombi basa kubvumira kutenderera kweropa mumuviri (moyo kutadza). 

Chekupedzisira, kushomeka uku kunogona kukonzera kuwedzera kwemidziyo (vasodilation) ichikonzera edema (kuzvimba) kwetsoka nemakumbo.

Kana kushomeka kuri kwakadzikama, chete mashoma mashoma-asina chaiwo zviratidzo anogona kuitika senge kuneta (nyoro asthenia), kusagadzikana, kukanganisika kwendangariro uye kurara.

Asi kana ichinyanya kududzwa, zviratidzo zvinoverengeka zvinobva zvavapo nenzira yematafura maviri:

Mune fomu yakaoma ne 

• symmetrical peripheral neuropathies (polyneuritis) pamativi ese ezasi emakumbo, nekunzwa kurira, kupisa, kupwanya, kurwadziwa mumakumbo;
• kuderedzwa kunzwisisika kwemakumbo ezasi (hypoaesthesia) kunyanya kudengenyeka, kunzwa kwekushaya simba;
• kuderedzwa kwemhasuru (atrophy) uye simba remhasuru zvichikonzera kunetseka mukufamba;
• kuderedzwa kana kunyange kubviswa kwetendon reflexes (Achilles tendon, patellar tendon, nezvimwewo);
• kunetsekana kusimuka kubva pakukwikwidza kuenda kunzvimbo yakamira;
• neurological zviratidzo nekuremara kwekufamba kwemaziso (Wernicke's syndrome), kunetseka kufamba, kuvhiringidzika kwepfungwa, kunetseka kutora matanho (abulia), amnesia nekuzivikanwa kwenhema (Korsakoff syndrome).

Mune fomu nyoro

• kukuvara kwemoyo nekutadza kwemoyo, kuwedzerwa kwemoyo (tachycardia), saizi yemoyo (cardiomegaly);
• yakawedzera jugular vein kumanikidza (mumutsipa);
• kupfupika kwemweya pakushanda (dyspnea);
• edema yemakumbo epasi (tsoka, gumbo, mhuru).

Kune aya zvakare zviratidzo zvekugaya mumhando dzakakomba idzi nemarwadzo emudumbu, kuda kurutsa, kurutsa. 

Chekupedzisira, muvacheche, mwana anorasikirwa nehuremu, akashoshoma kana kuti asingataure (haachemi kana kuchema zvishoma), anorwara nemanyoka uye kurutsa uye anonetseka kufema.

Kuwedzera bvunzo kunoitwa kana fungidziro yeBeriberi yekusimbisa kuongororwa uye kutora chiyero chekushomeka (thiamine mono uye diphosphate). Magnetic Resonance Imaging (MRI) yeuropi inogona zvakare kunyorerwa kuti zvionekwe zvisirizvo zvakabatana neVit B1 kushomeka (maronda ari maviri etalamus, cerebellum, cerebral cortex, nezvimwewo).

Kurapa kwechirwere cheBeriberi vhitamini B1 yekuwedzeredza nekukurumidza sezvazvinogona kudzivirira zvingangogadziriswa sequelae. Drug prophylaxis inogona zvakare kuiswa muzvinhu zviri munjodzi (nyaya dzinotambura nekugara uchinwa doro uye cirrhosis, varwere vasina kudya vane chirwere cheAIDS, kushaya zvinovaka muviri, nezvimwewo)

Chekupedzisira, kudzivirira kwezuva nezuva kunosanganisa kudya kwakasiyana-siyana nemarunda (pizi, bhinzi, nhokwe, nezvimwewo), zviyo (mupunga, chingwa uye gorosi rose, nezvimwewo), mbiriso dzakapfuma muVitamin B1 nembeu (walnuts, hazelnuts, glitches …). Iwe unofanirwa kudzivirira mupunga chena uye chero chinhu chakanatswa kwazvo seshuga chena uye kuona kugadzirira mukicheni kusingaparadze mavitamini akawandisa mukati.
