Mercury poisoning can occur through various means of exposure to mercury or its compounds. Here are the primary ways a person can be exposed:
- Inhalation of mercury vapors: This can happen in occupational settings where elemental mercury is used, such as in laboratories, battery manufacturing, or recycling processes. Inhaling mercury vapor can lead to neurological and respiratory problems.
- Consumption of contaminated food: One of the most common sources of mercury exposure is through eating fish and seafood that contain high levels of methylmercury, a toxic form of mercury. Large predatory fish, such as shark, swordfish, and king mackerel, tend to accumulate higher levels of mercury in their tissues.
- Exposure to mercury in dental amalgams: Dental fillings made from amalgam contain about 50% mercury. While the mercury in amalgams is generally considered safe, there is ongoing debate about potential long-term exposure, especially with excessive dental work.
- Skin contact: Some forms of mercury (like mercuric chloride) can be absorbed through the skin, although this is less common.
- Environmental exposure: Mercury can be released into the environment through industrial processes, waste incineration, and mining. Contaminated air, water, or soil can lead to indirect exposure.
- Accidental release: Lesser-known sources include breakage of thermometers, barometers, or other mercury-containing devices, leading to potential exposure from vapors or liquid mercury spills.
- Cosmetic products, vaccinations: Certain vaccinations and skin-lightening products may contain mercury, leading to exposure.
Exposure to high levels of mercury can lead to serious health issues, including neurological damage, cognitive impairments, and kidney problems. If mercury poisoning is suspected, it is essential to seek medical attention promptly.
Common symptoms associated with mercury toxicity include:
Neurological Symptoms:
- Cognitive dysfunction (memory problems, difficulty concentrating)
- Mood changes (irritability, anxiety, depression)
- Tremors or shaking
- Numbness or tingling in extremities
- Headaches
Physical Symptoms:
- Fatigue or weakness
- Muscle pain or weakness
- Gastrointestinal issues (nausea, diarrhea, abdominal pain)
- Respiratory problems (shortness of breath, cough)
Dermatological Symptoms:
- Rashes or skin irritation
- Changes in complexion or color
Sensory Symptoms:
- Vision problems (blurred or tunnel vision)
- Hearing loss or tinnitus (ringing in the ears)
- Altered taste or smell
Cardiovascular Symptoms:
- Increased heart rate (tachycardia)
- Blood pressure changes
Mercury toxicity may arise from various sources, including consumption of contaminated fish, exposure in industrial settings, dental amalgams (even during the process of removal).
When HTMA results show exposure to mercury or a person exhibits symptoms associated with mercury toxicity, it is crucial that we work together with a tailored functional nutrition plan and supplementation for at least 3 months before retesting with HTMA.
