Enzyme Replacement Therapy (ERT) is a medical treatment designed to provide patients with specific enzymes that their bodies are unable to produce. This therapy is commonly used for genetic disorders, such as Gaucher disease and Fabry disease, where the lack of certain enzymes leads to harmful substance accumulation in the body. By administering these enzymes, ERT helps to alleviate symptoms and improve the quality of life for affected individuals. The treatment is typically delivered through intravenous infusions and may require ongoing sessions depending on the patient's needs. While ERT can significantly enhance health outcomes, it does not cure the underlying genetic condition. Patients often work closely with healthcare providers to monitor their progress and adjust treatment as necessary.
