    La colestasi è una condizione in cui la secrezione o il trasporto della bile si riducono o si arrestano completamente. Come spiegato da Nia e Miles, il fegato funge da centrale logistica e, se questo ingranaggio si blocca, l'intero sistema va in tilt. Il problema può originarsi direttamente negli epatociti, le cellule che producono la bile, oppure lungo le vie biliari che trasportano il liquido verso l'intestino, compromettendo la corretta funzionalità epatica.

    La distinzione dipende da dove si verifica l'intoppo nel flusso biliare. Si parla di colestasi intraepatica quando il danno o il malfunzionamento avviene all'interno del parenchima epatico, coinvolgendo direttamente le cellule del fegato. Al contrario, la colestasi extraepatica è causata da un ostacolo fisico situato fuori dal fegato, come un calcolo o un tumore che preme sulle vie biliari, impedendo meccanicamente il passaggio della bile verso l'intestino.

    No, contrariamente a quanto si pensa comunemente, colestasi e ittero non sono sinonimi. Sebbene l'ittero, ovvero il colorito giallastro della pelle, sia un segnale tipico, Nia sottolinea che è possibile soffrire di una colestasi incompleta senza accorgersene visivamente per molto tempo. Questo rende la condizione particolarmente subdola, poiché il blocco della bile può persistere in modo silente prima che si manifestino sintomi evidenti o cambiamenti cromatici della cute.
