Chelation therapy refers to the medical practice of using chelating chemicals to eliminate harmful metals from the body. Toxic metals are bound to these agents, and the resulting complex is then excreted in the urine or feces. Heavy metal toxicity from substances like lead, mercury, and arsenic have been treated with chelation therapy, among other medical issues. Chelation therapy can be given intravenously (IV), orally (orally), or topically (on the skin). IV chelation, in which a chelating chemical is administered into the circulation, is the most prevalent kind of chelation therapy. After being absorbed into the bloodstream, the chelating agent travels throughout the body in search of hazardous metals to bind to. For many years, doctors have employed chelation therapy to treat patients who had been exposed to toxic levels of metals. Atherosclerosis (hardening of the arteries), peripheral arterial disease (PAD), and other cardiovascular disorders are among those for which it has been investigated as a potential alternative therapy. Chelation treatment has been advocated by some medical professionals and people as a way to treat cardiovascular disease and its associated symptoms including poor circulation and plaque buildup in the arteries.
