What is a common symptom of arsenic poisoning?

Arsenic poisoning is associated with a range of acute and chronic symptoms, and one of the hallmark signs of acute arsenic exposure is gastrointestinal distress. Vomiting and abdominal pain often occur shortly after ingestion of arsenic and can be quite severe. These symptoms arise because arsenic irritates the lining of the stomach and intestines, leading to inflammation and discomfort.

While nausea and headaches, constipation, or fatigue may also occur due to arsenic toxicity, they are not as commonly recognized as symptoms of acute poisoning. The gastrointestinal symptoms like vomiting and abdominal pain are more characteristic, making them a key indicator of arsenic exposure. This distinction helps in diagnosing arsenic poisoning effectively and allows for timely medical intervention to prevent further complications.
