Frequently asked questions

Dr. Shustina specializes in complex digestive and inflammatory conditions, including IBS, IBD, SIBO, bloating, reflux, food sensitivities, autoimmune-related gut disorders, and chronic gastrointestinal symptoms. Her work focuses on identifying root causes rather than managing symptoms alone.

Each consultation includes a comprehensive review of your medical history, prior testing, and records. Dr. Shustina provides personalized recommendations that may include advanced testing, nutrition and dietary guidance, supplements, lifestyle optimization, and mind-body strategies. You will receive a clear, individualized protocol and have ample time for questions.

Standard Consultation: 90 minutes (sufficient for most patients). Comprehensive Consultation: 105 minutes (recommended for complex medical histories or extensive records). This extended time allows for a thorough, integrative evaluation uncommon in traditional gastroenterology visits.

Dr. Shustina is an out-of-network provider and does not participate with commercial insurance plans, Medicare, or Medicaid. Payment is required at the time of scheduling. This model allows for longer visits, personalized care, and a true functional medicine approach.

Yes. Telehealth visits are available for patients who are physically located in New York, New Jersey, or Florida at the time of their appointment. You do not need to be a resident of these states, but you must be present in one of them during the visit.

Patients outside these states have several options: travel to an in-person visit (many patients choose the Miami location); travel temporarily to New York, New Jersey, or Florida for a telehealth visit; or schedule an educational visit for guidance and information to share with a local physician.

An educational visit provides detailed insight into your condition and Dr. Shustina's holistic approach to gut health. While medical advice, prescriptions, testing, and treatment orders cannot be provided, the information may help guide care with your local physician. Collaboration may be possible depending on state regulations.

Dr. Shustina combines board-certified gastroenterology with functional medicine, nutrition, nervous system regulation, and mind-body healing. Her approach is highly personalized, time-intensive, and focused on long-term healing rather than symptom suppression.
