Čo ak nič necítim? Čuch po covide sa musí trénovať štyrmi vôňami, radí expert

Aké dôležité sú pre nás chuť a čuch?

Čuch a chuť patria medzi zmysly, ktoré nás majú upozorniť na nebezpečné látky prítomné v ovzduší, na riziko požitia pokazenej stravy a čuch sa výrazne uplatňuje aj v sociálnej komunikácii, napríklad pri výbere partnera. Tieto zmysly často plnia svoju funkciu bez toho, aby sme si to plne uvedomovali. Teda žiť bez čuchu je obmedzujúce.

Poruchy čuchu a chuti boli zo začiatku pandémie veľmi častým prejavom covidu. Ako veľmi sa tento symptóm vyskytoval?

V jednej z prvých štúdií zameraných na poruchu čuchu a chuti u pacientov s covidom boli tieto príznaky popisované takmer u deväťdesiatich percent chorých, v neskorších štúdiách potom u šesťdesiatich percent.

Ide o úplnú stratu čuchu? Teda že človek necíti vôbec nič?

Spočiatku áno, následne je typická čiastočná strata a zmenené vnímanie pachových látok, ktoré označujeme ako parosmia. Ľudia síce vône a zápachy cítia, ich kvalita je ale zmenená – veľmi často cítia nepríjemné pachy. Pri čuchu a chuti je to rovnako ako s inými príznakmi, teda nemusia sa vyskytovať u všetkých pacientov. Úlohu hrá vek, pohlavie a tiež genetická predispozícia.
