What are early signs indicating lead poisoning in a patient?

Behavior changes are a key early sign indicating lead poisoning, particularly in children and, although less commonly, in adults. Lead exposure can affect the central nervous system, leading to various neurobehavioral effects. These changes may manifest as irritability, aggressive behavior, or decreased attention span. Early detection of these behavioral changes is crucial, as they can signal the impact of lead on cognitive and emotional development.

Weight gain and increased appetite are not associated with lead poisoning; rather, affected individuals may experience decreased appetite and weight loss. Severe headaches can occur with lead exposure but are often not the initial symptoms. Frequent urination is not a typical sign of lead poisoning and is more reflective of other medical conditions. Recognizing behavioral changes allows for timely intervention and management of lead exposure.
