Which symptom is commonly associated with lead poisoning?

Flu-like symptoms without fever are commonly associated with lead poisoning due to the physiological effects of lead on the body. In children, in particular, lead exposure can lead to symptoms such as irritability, loss of appetite, fatigue, and abdominal pain, which can mimic flu-like symptoms. The absence of fever is significant because it distinguishes these symptoms from typical viral or bacterial infections that generally present with an elevated body temperature.

Lead poisoning often leads to symptoms that are nonspecific and can be mistaken for other conditions, but the combination of gastrointestinal discomfort, malaise, and neurological effects like irritability aligns well with flu-like manifestations. This helps in recognizing lead poisoning as a potential cause of unexplained symptoms, especially in environments where lead exposure is a concern.
