A toxin is a substance that can cause harm to the body, particularly when present in excessive amounts. It can interfere with normal physiological processes and may place stress on the body’s regulatory systems.
Types of potentially harmful exposures
- Environmental chemicals and pollutants, such as heavy metals (e.g. lead, mercury) and industrial compounds
- Biological agents, including bacteria, viruses, and their by-products
- Diet-related substances, including food additives or metabolic by-products formed during digestion
- Medications and drugs, which can have side effects when misused or taken in excess
- Agricultural and household chemicals, such as pesticides or cleaning agents
- Radioactive substances, in rare or occupational exposure scenarios
- Foreign proteins, which may trigger immune responses in some individuals
- Emotional toxin, non-physical factors such as chronic psychological stress can influence overall health, although these are not classified as toxins in a strict medical sense
How the body manages these substances
The body has well-established systems for processing and eliminating potentially harmful substances. Key organs and systems involved include:
- The liver, which metabolises and neutralises many compounds
- The kidneys, which filter waste products from the blood
- The gastrointestinal system, which processes and excretes waste
- The immune system, which defends against biological threats
