Environmental Health & Allergy Center St. Louis is a medical practice with a different approach to understanding and treating chronic illnesses.

Our approach is to identify and treat the underlining cause of chronic illnesses. As a result, we reduce patient reliance on medications that simply mask their symptoms.

Environmental Health & Allergy Center is dedicated to treat patients suffering from a wide range of chronic ailments. This one stop facility is for the entire family. Dr. Sultan and his team focus on treating the genuine source of your symptoms. We teach our patients that by treating the core cause of their illnesses, they will become part of upstream medical care and can look forward to not only a reduction in symptoms, but an increase in overall wellness.  By applying the Principles of Functional Medicine, we provide the most effective and affordable care for our patients. Surprisingly, most people do not even know this option exists. Therefore, we wish to educate our patients, and provide them with the appropriate treatments and guidance to reach their healthcare goals.

As members of The Institute of Functional Medicine, the illnesses we commonly treat are asthma, hay fever, sinus problems, arthritis, colitis, digestive problems, chronic fatigue, fibromyalgia, depression, anxiety, OCD, hyperactivity in children and autism.
