Lead poisoning

Lead can be absorbed directly from blood into soft tissue and bone, where it can accumulate over time. Lead in bones can re-enter the bloodstream due to stress, pregnancy, menopause or prolonged immobilisation. Lead has the ability to inhibit basic enzyme function and promote free radical damage. In toxic quantities, lead can also damage the heart, kidneys, liver and nervous system. Children born to women with lead intoxication usually have growth retardation and nervous system problems.

Sources of lead exposure: lead-based paints, leading containing glassware, lead piping, lead petrol, canned fruit, Garden vegetables and insecticides.

Symptoms: gastrointestinal colic, muscle weakness, change in colour of the gums to blue, anxiety, confusion, arthritis, chronic fatigue, learning disabilities, loss of appetite, a metallic taste in the mouth, seizures, tremors and vertigo. Symptoms can develop over the course of weeks in adults and days in children.

Who to consult: chelation therapist, dietician, GP, herbalist, homoeopath, naturopath, paediatrician, psychologist.
