Ciguatera fish poisoning typically presents with a range of gastrointestinal, neurological, and cardiovascular symptoms. The onset of symptoms can vary, often appearing within a few hours to several days after consuming contaminated fish. Key symptoms include:

• Gastrointestinal Symptoms:
• Nausea
• Vomiting
• Diarrhea

• Abdominal pain

• Neurological Symptoms:

• Paresthesia (tingling or numbness)
• Reversal of hot and cold sensation (a hallmark symptom)
• Headaches
• Dizziness

• Muscle weakness

• Cardiovascular Symptoms:

• Bradycardia (slow heart rate)
• Hypotension (low blood pressure)
• Palpitations

Severity and Duration

The severity of symptoms can vary widely among individuals, with some experiencing mild symptoms while others may have severe reactions requiring hospitalization. Symptoms can persist for days to weeks, and in some cases, chronic symptoms may develop, including persistent neurological issues[2][5].
