Weight Loss & Increased Lead Levels

More than half the adults in the United States are overweight. Losing weight has many benefits, including a decreased risk for diabetes, heart attack and stroke. However, it is possible for weight loss, particularly rapid weight loss, to cause elevated lead levels. Conversely, poor appetite and weight loss are common symptoms of lead poisoning.

RISK

Rapid weight loss can negatively affect your health in several ways, with the possibility of lead toxicity being one of them. Your body stores heavy metals such as lead in fat tissues to prevent accumulation in your organs where damage can occur. Losing weight causes a redistribution of lead that can possibly elevate your levels. An animal study published in the August 1999 issue of the journal "Environmental Health Perspectives," found that rats with prior lead exposure were at an increased risk for weight loss-induced lead toxicity.

POISONING

Lead is a toxic metal. Excess exposure can cause reproductive problems in men and women, high blood pressure, muscle and joint pain, difficulty concentrating and nerve disorders. Lead is found in batteries, pipes, roofing materials and older homes painted with lead-based paint. Elevated levels can cause loss of appetite and weight loss. If you've noticed these symptoms and other lead poisoning symptoms, such as weakness and abdominal pain, your doctor can perform a test to measure your lead levels.

RAPID WEIGHT LOSS

If you are on a weight-loss regimen and you are concerned that it might place you at an increased risk for elevated levels, consult your dietitian. Losing weight at a slow and steady pace can help reduce your risk. Gastric bypass is a weight loss procedure that results in rapid weight loss. If you have undergone this type of weight loss measure, your doctor can monitor your lead levels over the course of your weight loss.

CONSIDERATIONS

Trace minerals such as cobalt, which is found in B-12, zinc and copper, exert a protective effect against lead toxicity, according to nutritionist Eric Dicyan, author of "A Beginner's Introduction to Trace Minerals." Maintaining adequate amounts of these minerals might help protect your liver and kidneys against the effects of elevated lead levels. If you are starting a weight loss regimen, your physician can measure your levels of these important minerals.
