    For me, trust is the keystone upon which I form the relationships with my patients. Trust is important when asking a patient to share details of problems that can often be embarrassing. And trust is important when asking a patient to let me help them solve their problems, some of which may have been ongoing for years. In order to build that trust, I show my patients warmth and compassion, I listen fully and intently, and I show my patients a warmer side of medicine. My parents immigrated from El Salvador and made it a point to raise me bilingual. This helps me connect more deeply with a group of patients who might not otherwise be completely understood.I enjoy the clinical variety that Gastroenterology provides. The complexity of the health and disease of the GI tract challenges my mind. At the same time, I always enjoy the hands-on element that the procedures provide. I am methodical and detail-oriented on the one hand, yet warm and friendly on the other. I always make sure to educate my patients fully, so they can make informed decisions and take an active role in their own care.Born and raised in Los Angeles, Dr. Castillo drags her family to the beach as often as possible.

    What is the definition of Lactose Intolerance?

    Lactose is a type of sugar found in milk and other dairy products. An enzyme called lactase is needed by the body to digest lactose.

    Lactose intolerance develops when the small intestine does not make enough of this enzyme.

    When should I see a Lactose Intolerance doctor in Arizona, 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 a Lactose Intolerance doctor in Arizona, 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 does MediFind rank Lactose Intolerance doctors in Arizona, 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 Lactose Intolerance doctors in Arizona, 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 a Lactose Intolerance doctor in Arizona, 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 Lactose Intolerance doctor search results page. 

    Why is it important to get a second opinion from a different Lactose Intolerance 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 Lactose Intolerance doctor in Arizona, 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 Lactose Intolerance 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 Lactose Intolerance 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 Lactose Intolerance doctors in Arizona, US?

    Look for the filter feature on the left side of the Lactose Intolerance 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 Lactose Intolerance doctor that offers video calls?

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