the body's polite warning before it stages a full revolt.

means Feeling slightly nauseous or uneasy, as if your stomach might turn at any moment.

from A late-medieval English word, originally something like 'coisy' or 'queisy,' meaning unsettled or unsteady. Its deeper roots are murky — possibly tied to Old French 'coisier' (to wound or hurt) or related to a Scandinavian word for bruise or hurt. The spelling wobbled for centuries before settling, which feels fitting for a word about not feeling quite right.
