From the Guidelines

Lead poisoning symptoms can vary depending on the level of exposure, but early detection is crucial to prevent long-term complications, and blood tests measuring lead levels are essential for confirmation 1.

Symptoms of Lead Poisoning

The symptoms of lead poisoning can affect multiple body systems and may include:

  • Fatigue, irritability, abdominal pain, headaches, and difficulty concentrating
  • Persistent vomiting, muscle weakness, seizures, and encephalopathy at higher levels of exposure
  • Developmental delays, learning difficulties, hearing loss, and behavioral problems in children
  • High blood pressure, joint pain, reproductive issues, and kidney dysfunction in adults

Importance of Early Detection

Symptoms can appear gradually and may be mistaken for other conditions, making diagnosis challenging 1.

Treatment and Prevention

Treatment involves removing the source of exposure, chelation therapy with medications like succimer (DMSA), EDTA, or dimercaprol for high levels, and supportive care 1.

High-Risk Groups

Lead poisoning is particularly dangerous for children and pregnant women as it can cause permanent neurological damage and developmental issues 1.

Recommendation

If you suspect lead exposure, seek immediate medical attention, as early intervention is crucial to prevent long-term complications 1.
