    Philosophy of care | I strongly believe health care access should be for all. Regardless of their socio-economic status, religious background and beliefs, every person should have access to quality health care. I try to participate in free clinics set up by my mosque and eagerly supervise residents and fellows at Lehigh Valley Hospital clinics serving indigent patients. | Why I entered medicine | The field of medicine has the pulse of society. A caring doctor not only knows a patient's medical problems, but also is closely aware of the patient's circumstances and living environment. I entered medicine because I love science and for the dignity and respect doctors carry in society. | Community involvement | During more than two decades in the Lehigh Valley area, I have been involved through my mosque in community projects such as free clinics and soup kitchens. I have participated in LVHN charity walks and colorectal cancer awareness events. I also have been an active member of the Association of Physicians of Pakistani Descent of North America, which undertakes educational and legislative campaigns. | Personal interests | I am interested in reading world history, enjoy listening to music and watching cricket. I enjoy long walks and pickleball. Dr. Imam is rated as an Advanced provider by MediFind in the treatment of Diarrhea.

    Philosophy of care | For health to work, it truly needs to be individualized and centered on you. Everyone is different and it's hard to fit everyone into a medical textbook mold. I believe many things can be achieved by understanding disease processes, and sometimes less is more. Medications and procedures all have risks and benefits and deciding what truly needs to be prescribed or done is a discussion between me and you. Just because something can be done doesn't always mean it should be done. | Why I entered medicine | I entered medicine to help people take control of their health, feel empowered and make positive life changes based on informed decisions with me as a guide. Understanding the human body is challenging and it’s my job to translate all the medical jargon so you understand what is happening to you, why it is happening and what options you have. I've always viewed medicine as a partnership with patients and not a dictatorship; most people enjoy being in control of their own bodies and health. | Personal interests | I spend most of my free time outside with my husband and daughters hiking, biking, jogging or snowboarding and just living and being in the moment. Dr. Patek is rated as an Advanced provider by MediFind in the treatment of Diarrhea. Her top areas of expertise are Gastroesophageal Reflux Disease (GERD), Gastritis, Chronic Erosive Gastritis, Endoscopy, and Colonoscopy.

    What is the definition of Diarrhea?

    Diarrhea is when you pass loose or watery stool.

    When should I see a Diarrhea doctor near Allentown, PA?

    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 Diarrhea doctor near Allentown, PA?

    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 Diarrhea doctors near Allentown, PA?

    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 Diarrhea doctors near Allentown, PA?

    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 Diarrhea doctor near Allentown, PA?

    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 Diarrhea doctor search results page. 

    Why is it important to get a second opinion from a different Diarrhea 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 Diarrhea doctor near Allentown, PA?

    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 Diarrhea 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 Diarrhea 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 Diarrhea doctors near Allentown, PA?

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

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