Chelation therapy is a medical treatment that involves the administration of chelating agents to remove heavy metals and other toxins from the body. These agents bind to harmful substances, allowing them to be excreted through urine. It is often used to treat heavy metal poisoning, such as lead or mercury exposure. In addition to treating poisoning, some people use chelation therapy for other health conditions, including cardiovascular disease and autism. However, its effectiveness for these uses is still debated, and it is important to consult a healthcare professional before undergoing this treatment.
