Introduction

Lead poisoning is a serious health concern that can affect people of all ages, especially children. Since lead is a toxic metal, exposure to even small amounts over time can cause harmful effects on the body. Recognising the symptoms early can help prevent long-term damage.

In this article, we’ll discuss: What is lead poisoning, common symptoms in adults and children, causes and risk factors, how to prevent and manage lead exposure and when to seek medical help

What is Lead Poisoning?

Lead poisoning occurs when lead builds up in the body over time, usually through repeated exposure to lead-contaminated substances. Lead can enter the body through:

Inhalation (breathing in lead dust or fumes), Ingestion (eating or drinking contaminated food, w

later, or objects)

Once inside the body, lead travels through the bloodstream and gets stored in bones, teeth, and soft tissues, leading to various health problems.

Symptoms of Lead Poisoning

Lead poisoning often develops slowly, and symptoms may not appear immediately. In some cases, people may not realise they’ve been exposed until severe symptoms arise.

Symptoms in Children

Children are more vulnerable to lead poisoning because their bodies absorb lead more easily. Even low levels of lead exposure can affect a child’s growth and brain development. Common symptoms include:

  • Learning difficulties (trouble focusing, lower IQ)

  • Behavioural problems (hyperactivity, irritability, aggression)

  • Fatigue and sluggishness

  • Loss of appetite and weight loss

  • Abdominal pain and vomiting

  • Constipation

  • Hearing loss

  • Delayed growth

  • Seizures (in severe cases)

Symptoms in Adults

Adults exposed to lead may experience:

  • High blood pressure

  • Joint and muscle pain

  • Headaches

  • Memory and concentration problems

  • Mood disorders (depression, irritability)

  • Abdominal cramps

  • Reduced sperm count (in men)

  • Miscarriages or premature births (in pregnant women)

Causes and Risk Factors

Lead poisoning usually occurs due to exposure in everyday environments. Common sources include:

  • Old lead-based paint (common in homes built before 1978)

  • Contaminated water (from lead pipes or plumbing)

  • Certain jobs (battery manufacturing, construction, painting)

  • Traditional remedies or cosmetics (some contain lead)

  • Imported toys, jewellery, or ceramics (may have lead-based paint or glaze)

  • Soil contamination (near highways or industrial areas)

Children are at higher risk because they often put objects in their mouths and absorb lead more easily.

How to Prevent Lead Poisoning?

Preventing lead exposure is the best way to avoid poisoning. Here’s what you can do:

For Homes with Lead Paint

  • If your home was built before 1978, get it tested for lead.

  • Keep painted surfaces in good condition (peeling paint increases exposure).

  • Use wet cleaning methods to reduce dust.

Safe Drinking Water

  • Run cold water for 30 seconds before drinking if pipes are old.

  • Use a water filter certified to remove lead.

Healthy Diet

  • Eating foods rich in iron, calcium, and vitamin C can help reduce lead absorption.

  • Examples: Milk, yoghurt, leafy greens, citrus fruits, beans, and lean meats.

Workplace Safety

  • If you work with lead, follow safety guidelines (wear masks, wash hands, change clothes before going home).

When to See a Doctor?

If you or your child experiences symptoms of lead poisoning, consult a doctor immediately. A simple blood test can confirm lead levels in the body. Early detection helps prevent complications.

Treatment Options

  • Mild cases: Remove the source of lead and monitor health.

  • Severe cases: Chelation therapy (medication to remove lead from the blood).

Final Thoughts

Lead poisoning is preventable with awareness and precautions. If you suspect exposure, getting tested is crucial, especially for children, as lead can cause irreversible damage to their development.
