Chelation therapy

Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. Chelation therapy has a long history of use in clinical toxicology and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks.

History

The concept of chelation therapy began in the early 20th century with the development of ethylene diamine tetraacetic acid (EDTA), a synthetic amino acid and chelating compound. EDTA was first used in the 1940s for the treatment of lead poisoning.

Mechanism of action

Chelation therapy works by forming a chemical bond with certain metals in the body, allowing them to be easily filtered out by the kidneys and excreted in urine. The chelating agent may be administered intravenously, intramuscularly, or orally, depending on the agent and the type of poisoning.

Uses

Chelation therapy is used as a treatment for acute and chronic heavy metal poisoning, such as lead poisoning or iron overload. It is also used in the treatment of heart disease and autism, although these uses are controversial and not widely accepted in the medical community.

Risks and side effects

Chelation therapy can have serious side effects, including kidney damage, irregular heartbeat, and low blood pressure. It can also cause a severe allergic reaction. Because of these risks, chelation therapy should only be administered under the supervision of a medical professional.
