Lead Poisoning: Causes, Symptoms, Prevention, and Treatment of a Serious Health Problem

Overview Types Causes & Risk Factors Symptoms Preventions Treatment

Overview

Lead poisoning occurs when lead builds up in the body, often over months or years. Even small amounts of lead can cause serious health problems. Children younger than 6 years are especially vulnerable to lead poisoning, which can severely affect mental and physical development. At very high levels, lead poisoning can be fatal.

Types of Lead poisoning

There are several types of lead poisoning, including:

Acute lead poisoning: This occurs when a person is exposed to a large amount of lead in a short period.
Chronic lead poisoning: This occurs when a person is exposed to small amounts of lead over a long period.
Subacute lead poisoning: This occurs when a person is exposed to a moderate amount of lead over a period of weeks or months.

Causes of Lead poisoning

The most common causes of lead poisoning are:

Lead-based paint and lead-contaminated dust in older buildings.
Contaminated air, water, and soil.
Workplace exposure to lead (e.g., battery manufacturing, construction).
Home renovation activities that disturb lead-based paint.

Risk Factors of Lead poisoning

Certain individuals may be more at risk of developing lead poisoning due to:

Age (children under 6 years are most vulnerable).
Exposure to known sources of lead.
Family history of lead poisoning.
Poor nutrition and inadequate diet.
Certain medical conditions (e.g., anemia).
