      Last Updated: 10/30/2025

      What is the definition of IgG4-Related Disease?

      IgG4-related disease (IgG4-RD) is an autoimmune disorder in which patients have elevated blood levels of IgG4, the most common form of immunoglobulin that circulates in the blood. Increased levels of IgG4 can cause inflammation in a single organ or in multiple organs, such as the meninges (tissue surrounding brain and spinal cord), the eye sockets, lacrimal (tear duct) glands, salivary glands, thyroid gland, lungs, aorta, kidneys, bladder, pancreas, and bile ducts. IgG4-related disease most often affects middle-aged and elderly males, and rarely, children.

      When should I see an IgG4-Related Disease doctor in Illinois, US?

      There are various reasons why you may want to see a specialist, such as: 

      • Your primary care provider recommends it. 
      • Your condition requires expert knowledge and specialized care. 
      • Your symptoms persist or worsen despite treatment. 
      • You need specialized testing or procedures. 
      • You want a second opinion.  

      What should I consider when choosing an IgG4-Related Disease doctor in Illinois, US?

      It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

      How do I find the best IgG4-Related Disease doctor in Illinois, US?

      You can find an IgG4-Related Disease doctor in any of the 10 largest U.S. cities by clicking below:

      IgG4-Related Disease doctor near New York, NY
      IgG4-Related Disease doctor near Los Angeles, CA
      IgG4-Related Disease doctor near Chicago, IL
      IgG4-Related Disease doctor near Houston, TX
      IgG4-Related Disease doctor near Phoenix, AZ
      IgG4-Related Disease doctor near Philadelphia, PA
      IgG4-Related Disease doctor near Atlanta, GA
      IgG4-Related Disease doctor near Boston, MA
      IgG4-Related Disease doctor near Dallas, TX
      IgG4-Related Disease doctor near San Jose, CA

      How does MediFind rank IgG4-Related Disease doctors in Illinois, US?

      MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

      What types of insurance are accepted by IgG4-Related Disease doctors in Illinois, US?

      Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

      How can I book an appointment online with an IgG4-Related Disease doctor in Illinois, US?

      MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the IgG4-Related Disease doctor search results page. 

      Why is it important to get a second opinion from a different IgG4-Related Disease doctor?

      Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

      How can I prepare for my appointment with an IgG4-Related Disease doctor in Illinois, US?

      Prepare for your appointment by gathering the following items: 

      • Copies of medical records (dating back at least one year) 
      • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
      • Family history of disease 
      • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
      • Allergies to medications, food, latex, insects, etc.  
      • List of questions and concerns 
      • Your insurance card 

      You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

      What questions should I ask my IgG4-Related Disease doctor?

      Here are some sample questions: 

      • Can you explain in simple terms what this condition is and how it’s treated? 
      • What symptoms or side effects should I watch for? 
      • What tests will be involved, and when can I expect results? 
      • Are there other specialists I need to see? 
      • What’s the best way to reach you if I have follow-up questions? 

      How can I learn about the latest clinical trials and research advances my IgG4-Related Disease doctor may know about?

      MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

      MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

      Can I filter my search to show male or female IgG4-Related Disease doctors in Illinois, US?

      Look for the filter feature on the left side of the IgG4-Related Disease doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

      Can I filter my search to find an IgG4-Related Disease doctor that offers video calls?

      Look for the filter feature on the left-side of the IgG4-Related Disease doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
