Which of the following is a common symptom of copper poisoning?

Copper poisoning is characterized by several symptoms, with nausea and vomiting being particularly common. When copper accumulates in the body, it can irritate the gastrointestinal tract, leading to these symptoms as the body attempts to expel the excess copper. This reaction can be quite severe, often resulting in acute abdominal pain along with nausea and vomiting.

In contrast, while drowsiness, headache, and rapid heartbeat can occur in various types of poisoning or health issues, they are not hallmark symptoms of copper poisoning specifically. Understanding these symptoms is crucial for identifying and responding to copper toxicity effectively.
