"Infusion" or "infusion therapy" refers to administering medications and/or fluids directly into a person's vein. It is also known as intravenous or IV infusion. Infusion, intravenous, or injectable methods of medication delivery are generally used when oral/pill medications are insufficient, unavailable, or inappropriate. Many of the newest medications are derived or made from living cells (biologic), which cannot be taken orally, like a pill, because they are no longer effective once exposed to the gastrointestinal system. Biologic medications are often used to treat inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis, along with other autoimmune disorders. To find a provider who offers infusion therapy in St. Louis, MO, request a consultation at a local Specialists in Gastroenterology in your community.

Other than being incredibly bright, Dr Root is refreshingly kind and compassionate. He communicates clearly so that you understand your diagnosis and treatment options. He is consistently a personable doctor. He actually listens and seems to genuinely care about you. He answers questions in a clear fashion. He calls with lab results in a timely manner., with clear guidance for follow up. I feel fortunate to have him as a GI provider for my family member.
