Understanding Heavy Metals Toxicity
Heavy metals are elements found naturally in our environment. Some like zinc or copper are essential in small amounts, while others such as lead, mercury, arsenic, cadmium and aluminum are harmful even at low levels. Exposure can occur through water, food, air, dust or everyday products.
Sources of Exposure
- Water: Old plumbing, industrial runoff, contaminated wells
- Food: Certain fish, shellfish, imported produce or crops grown in polluted soil
- Air: Industrial emissions, traffic-related particulates, smelting byproducts
- Consumer goods: Imported toys, ceramics, jewelry, some cosmetics or supplements
Symptoms of Heavy Metal Toxicity
Symptoms vary by the type of metal, exposure level and individual susceptibility.
Common symptoms
- Headaches, dizziness, tremors, memory loss, confusion, numbness or tingling in hands or feet
- Nausea, vomiting, diarrhea, abdominal pain
- Fatigue, mood changes, weight loss, impaired immunity
- Shortness of breath, coughing, chest tightness
- Muscle weakness, joint pain, rashes, itching, skin discoloration
- Irregular heartbeat, high blood pressure
- Kidney stress or altered urine output
- Anemia or bleeding tendencies
Why Functional Medicine Testing Matters
Standard blood or urine tests often only detect recent exposure and may miss the cumulative “body burden” stored in tissues. In functional medicine we use a more comprehensive strategy that balances accuracy with patient safety.
- Blood panels: Measure current levels of metals such as lead, mercury, arsenic, cadmium
- Urine testing without provocation: We use non-provoked urine collection to reduce patient stress and risk. This helps assess ongoing exposure and excretion without burdening the body
- Expanded functional labs: When indicated we also evaluate detox pathways, oxidative stress markers, thyroid and nutrient status to see how metals are affecting broader systems
How We Approach Treatment
- Remove exposure sources: Filter water, avoid contaminated foods, replace toxin-laden items
- Support natural detox pathways: Use diet, nutrients, hydration and lifestyle measures to optimize liver, kidney and skin function
- Targeted Chelation (when clinically appropriate): EDTA or other agents may be used under supervision to support safe excretion of metals and to address cardiovascular risk
- Targeted nutrient and antioxidant support: Zinc, selenium, vitamins C and E, B complex and minerals to reduce oxidative stress and replenish deficiencies
- Functional follow up: Re-test and adjust the plan based on lab trends and how symptoms improve
Prevention & Lifestyle Measures
- Use certified water filters for lead and mercury
- Favor home-cooked meals with low-toxin ingredients
- Avoid aluminum cookware, unregulated supplements or imported products of uncertain safety
- Incorporate sweating through regular sauna, infrared therapy or exercise to support toxin elimination
- Maintain a nutrient-dense diet rich in vegetables, fruits and whole foods for detox and antioxidant support
In Summary
Heavy metal toxicity can present subtly and overlap with many other health concerns. At Glendale Whole Health we identify hidden exposures, assess body burden through safe testing, and create personalized detox and resilience plans.
