Onset of gastrointestinal symptoms after exposure to ciguatera toxin?

Explanation:
Ciguatera toxin affects the gut quickly, so GI symptoms tend to appear within a few hours after ingestion. The typical window is about three to five hours. This aligns with how the toxin stimulates enteric nerves and the vomiting center, leading to nausea, vomiting, and diarrhea soon after exposure. While some variability exists, immediate onset is uncommon, and delays like 12–18 hours or 24–48 hours are later than the usual GI presentation.
