Every day in practice, women present with high lead levels in their blood. The source is not always external.
Lead gets stored in bone over decades of exposure. When bone turnover increases, whether from perimenopause, postmenopause, or the persistent inflammation seen in complex chronic illness, that stored lead gets released back into circulation. Women can become their own source of lead toxicity.
Testing should include markers for bone turnover to understand the mechanism. Treatment requires stopping bone loss first before beginning lead detoxification.

The impact of metal toxicity on your body extends far beyond brain fog. Many people experience changes in their personality or emotional responses that they might not initially connect to metal toxicity. You might find yourself more irritable, anxious, or experiencing mood swings that seem out of character.
When metals affect your nervous system, the implications go beyond simple cognitive changes. Some people notice changes in their handwriting, balance, or fine motor skills. Sleep patterns often become disrupted, not just in terms of difficulty falling asleep, but also in the quality and depth of sleep.
Metal toxicity can impact every aspect of health in ways that might not be obviously connected to toxic exposure, which is why comprehensive testing with practitioners trained in environmental medicine is critical.

Foods considered healthy can still carry a metal burden. The source, soil, and processing all matter.
Fish like tuna and salmon accumulate mercury. Rice absorbs arsenic from soil and water. Chocolate, apple juice, spinach, sweet potatoes, and bone broth have all tested for lead or cadmium depending on origin.
A clean diet does not automatically mean a low metal diet. Understanding where metals hide is the first step in reducing exposure.

Metal toxicity is often overlooked in chronic illness, yet it acts as a significant contributor to health challenges. Most patients aren't dealing with just one metal. Several different metals accumulate simultaneously from water, food, dental work, and the environment, each affecting health in different ways.
When metals accumulate, they don't sit passively. They interact with biological systems and disrupt normal functions, creating a cascade effect where one system's dysfunction leads to problems in others. This explains why symptoms seem unrelated but stem from the same underlying causes.
Basic metal testing only shows current circulating levels in blood or urine. Metals stored deeper in tissues require challenge testing administered by practitioners trained in proper chelation therapy to reveal true toxic burden.

Patients with high mercury levels very often report eating a pristine diet. Then they mention they eat a lot of fish.
Even fish once a week can produce unacceptably high levels. Most people know tuna and sea bass are high in mercury. But salmon, the fish considered safer and lower in mercury, is still showing up for high mercury on labs. Patients eating salmon regularly are testing with elevated blood levels that need to be addressed.
What is considered a clean diet does not necessarily equate to a mercury free diet.

Heavy metal exposure doesn't come from a single source. It accumulates from multiple places in your daily environment, from the cosmetics you apply every morning to the water you drink, the cookware you use, and the buildings where you work.
Personal care products imported from countries with different safety standards can contain lead, mercury, arsenic, and cadmium. Traditional medicines and supplements that aren't properly tested add to the burden. Even homes built before the 1970s contribute through lead paint and old pipes that leach metals into filtered water.
The challenge with metal toxicity is that most patients are dealing with several different metals at once, each coming from various sources in their environment. These exposures add up over time, creating a toxic load that your body struggles to eliminate through natural detoxification pathways.

The connection between chronic infections and craniocervical instability is one of the most under-discussed topics in complex chronic illness, and it is affecting far more patients than most clinicians realize.
On February 19th at 3 PM PST / 6 PM EST, Dr. Eric Gordon and Dr. Centeno are going live on Facebook and YouTube on Centeno-Schultz Clinic to break this down, what the research shows, what they are seeing clinically, and what options are being explored.
There will be an extensive Q and A so bring your questions directly to both doctors. Set your reminder now.

Most doctors do not test for heavy metals. And when they do, the approach is often incomplete.
Unprovoked blood and urine testing should come first, with results compared against the CDC NHANES population data. A patient at the 75th percentile is likely experiencing some pathological effect from that metal. At the 90th percentile, acute exposure is indicated and the source must be identified and removed before provoked testing even enters the conversation.
Without this baseline, treatment decisions are built on incomplete information.

Each exposure to heavy metals adds to your body's total toxic burden. Mercury from dental fillings, lead from old paint and pipes, arsenic from contaminated water, cadmium from pesticides. Over time, these can accumulate faster than your body may be able to eliminate them.
When your detoxification pathways are compromised, whether due to genes of detoxification or chronic inflammation, the burden becomes even heavier. The container fills, and your body can no longer disperse the toxins effectively.
This accumulation leads to brain fog, sleep disruption, hormonal imbalance, autoimmune flares, and chronic disease. The symptoms seem unrelated, but they share the same underlying cause: a toxic load your body wasn't designed to handle.

Patients with mast cell reactions and food sensitivities often turn to restrictive diets for relief. While minimizing gut inflammation matters, these diets frequently continue for months or even years.
The problem is nutrient depletion. Trace minerals and vitamins are essential for mitochondrial function. Without them, it does not matter how much injectable NAD you take. NAD works through recycling, and that process requires trace minerals. When those run low, mitochondria cannot function appropriately. Fatigue increases. The immune system loses control. Patients get sicker.
Three weeks of restriction is one thing. Three months, maybe. But beyond that, it is critical to ensure you are not starving your mitochondria of what they need to produce energy.
