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

Nausea and vomiting are common symptoms of pesticide poisoning due to the toxic effects that many pesticides have on the human body. When someone is exposed to these chemicals, whether through ingestion, skin contact, or inhalation, they can irritate the gastrointestinal tract and affect the brain's ability to regulate nausea, leading to these symptoms. Symptoms of pesticide poisoning can vary depending on the specific chemical involved and the level of exposure, but nausea and vomiting are frequently reported reactions in many cases.

In contrast, excessive thirst might be associated with dehydration but is not a direct symptom of pesticide exposure. Increased appetite usually indicates good health and digestive function, rather than a reaction to toxins. Relief from allergies does not correlate with pesticide exposure; in fact, exposure may lead to adverse health effects. Understanding the typical reactions to pesticide exposure helps in identifying symptoms early and seeking appropriate medical attention.
