Pediatric gastroenterologists specialize in diagnosing and treating a wide range of issues that require knowledge in multiple areas of pediatric medicine and medicine in general. They have deep knowledge of nutrition, including baby formulas, gastrostomy, and nasogastric tube feeds. They work with children with failure to thrive, liver issues, metabolism problems, infections, and autoimmune inflammation. The spectrum of pediatric gastroenterology expertise is broader than just luminal/intestinal issues such as constipation, diarrhea, vomiting, gastritis, enteritis, and colitis.

The key to proper diagnosis is a methodical work-up that parents must respect and follow. Lab work, including blood work and stool samples, is ordered and sent directly to the laboratory indicated by the family. It may require fasting if it includes cholesterol or sugar-related evaluation. Stool containers are picked up by laboratory technicians with instructions on how to collect and store them. Blood and stool studies provide essential information about infectious, absorptive, genetic, and inflammatory processes inside the body.

Radiology studies, such as x-ray, CT scan, MRI, and ultrasound, allow for the viewing of hollow organs’ (stomach and intestine) structure, muscle and nerve function, solid organs’ (liver, kidneys, pancreas) damage, congenital anatomical issues, and inflammation. Endoscopy is only done if indicated by clinical picture, laboratory, and/or radiological studies.

If any of the above studies have been done by the emergency room, pediatrician, or gastroenterologist before your appointment with our pediatric GI specialist, please fax it to 866-586-6011 at least 24 hours before the appointment. This will help us provide the best care for your child in the most efficient way.

Dr. Treskova took her time getting to know our son's GI situation. She gave practical home remedies along with sound nutritional advise. It took a few months of dedicated work on our end plus continued follow up with the doctor for him to ultimately improve. Thank you Dr. Treskova for hanging in there with us!

Dr Treskova is incredibly thorough, competent, and kind. She leaves no stone unturned when trying to figure out what is causing your child's GI issues. We really enjoy our visits with her and know my daughters are getting the best care possible. I would highly recommend her to anyone looking for a pediatric gastroenterologist/hepatologist.

Our first visit was very reassuring. It worked out that the initial was a virtual for our situation. Dr. Treskova was that perfect mix of compassionate, factual, and reassuring. She listened and gave helpful feedback. When the appointment ended I felt like we might finally be on the path to get answers for my little one. He is a 6 year old boy on the spectrum with no verbal communication. It can be very difficult to find doctors that understand the level of patience that is needed. I wish I could find this in every specialty.

Dr. Treskova comes highly recommended at this time. My son has been struggling with learning challenges for quite some time. Through her dedication and diagnostic testing, we were able to get to the root cause of his gastrointestinal issue. She recommends food based and supplements (holistic approach), in conjunction with medicine, to achieve the highest and safest outcomes. This is so important as a parent of a young one, to be able to treat them safely. Because of Dr. Treskova, for the first time, we feel optimistic our son is on his way to recovery. She also is very patient and takes the time to view and discuss the patient as a whole. Her guidance, knowledge, and commitment are truly amazing. I’m so grateful to be working with her.

My daughter loves Dr Treskova and how she has clearly listened to her, understands her complaints and has given her so many natural ways of handling her Gastro issues. Dr. Treskova communicates one on one with my daughter on a level that my daughter understands. Dr. keeps her explanations simple for her to understand her digestive system health and how the brain , gut and bowels are all interconnected with each other She has been through with asking questions wanting feedback has to what is or has not been working for my daughter. Dr Treskova is professional but most importantly sincerely cares about her young patients. As a parent that is so important and so reassuring that my child is being well taken care of.

Dr Treskova is a very knowledgeable gastroenterologist, who keeps up with the newest treatments protocols and medical updates. Despite the pandemic and being limited to providing virtual exams, she was very thorough in obtaining a medical history (one of the most important part of making the diagnosis) and doing her best to perform the exam. She understands the challenges of being a mother and is very realistic with the goals she sets for children. I truly appreciated the tips that she provided me with to help my kids feel better.
