Etymologically, the entry records: From Middle English sik, sike, seek, seke, seok, from Old English sēoc (“sick, ill”), from Proto-West Germanic *seuk, from Proto-Germanic *seukaz, from Proto-Indo-European *sewg- (“to be troubled or grieved”). See also West Frisian siik, Dutch ziek, German … Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is sick, spelled S-I-C-K, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
