    What is the definition of Chronic Idiopathic Constipation (CIC)?

    Chronic idiopathic (of unknown cause) constipation is a persistent condition that mainly affects females and older adults and is characterized by infrequent, hard, and lumpy stools that are extremely difficult to pass. This creates a buildup of stool in the colon that causes extreme abdominal and pelvic pain. While the cause is unknown, chronic idiopathic constipation may be triggered by reduced fluid and fiber intake; the use of certain medications, such as antihistamines, antipsychotic medications, opioids, general anesthetics, and antiparkinsonian drugs; changes in the colon; rectocele (rectum bulging into vagina); rectal prolapse (rectum protrudes through the anus); or dyssynergic dysfunction (disorder of muscles and sphincters that control defecation).

    When should I see a Chronic Idiopathic Constipation (CIC) doctor in Japan?

    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 a Chronic Idiopathic Constipation (CIC) doctor in Japan?

    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 Chronic Idiopathic Constipation (CIC) doctor in Japan?

    How does MediFind rank Chronic Idiopathic Constipation (CIC) doctors in Japan?

    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 Chronic Idiopathic Constipation (CIC) doctors in Japan?

    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 a Chronic Idiopathic Constipation (CIC) doctor in Japan?

    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 Chronic Idiopathic Constipation (CIC) doctor search results page. 

    Why is it important to get a second opinion from a different Chronic Idiopathic Constipation (CIC) 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 a Chronic Idiopathic Constipation (CIC) doctor in Japan?

    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 Chronic Idiopathic Constipation (CIC) 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 Chronic Idiopathic Constipation (CIC) 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 Chronic Idiopathic Constipation (CIC) doctors in Japan?

    Look for the filter feature on the left side of the Chronic Idiopathic Constipation (CIC) 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 a Chronic Idiopathic Constipation (CIC) doctor that offers video calls?

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