The Practice

Manhattan Integrative Gastroenterology is a full service digestive disease health and wellness practice. We provide complete digestive care with standard, functional, nutritional, and holistic evaluations in order to get to the core of the problem. Conventional medicine has excelled in advanced diagnostic technology treating acute medical problems and emergencies. Chronic illness has not been adequately addressed with conventional methods. Functional and integrative medicine has been able to tackle chronic conditions in a holistic and safe way. It is therefore, imperative that all modalities are available.

Similar symptoms do not mean the root cause is the same. Each patient is unique with a distinct profile and we customize each treatment to each patient’s unique and special needs.

The digestive system is the entry point for disease and for health and is an integral barrier to maintain health in all systems. A healthy digestive system is vital to avoid and treat autoimmune conditions, hormonal imbalances, maintain a healthy immune system, and a healthy metabolic profile.

The practice is located in the heart of downtown Manhattan in the Flatiron district. It is the only Integrative Gastroenterology practice in the Metro area.
