For centuries, lead toxicity has been one of the most significant preventable causes of neurologic morbidity from an environmental toxin. A heavy metal, lead is ubiquitous in our environment but has no physiologic role in biological systems.
In adults, exposure to lead may be short-term or chronic. Repeated or chronic exposure can cause lead to accumulate in your body, leading to lead poisoning. Lead poisoning can cause metallic taste, poor appetite, weight loss, colic, upset stomach, nausea, vomiting, and muscle cramps. Short-term exposure to lead can irritate the eyes on contact and cause high blood pressure, headache, irritability, reduced memory, disturbed sleep, and mood and personality changes.
