The International Society for Environmentally Acquired Illness

ISEAI is a nonprofit professional medical society that aims to raise awareness of the environmental causes of inflammatory illnesses and to support the recovery of individuals affected by these illnesses through the integration of clinical practice, education, and research.


It is no secret that many patients today are sicker and their illnesses are more complex than they were even 20 years ago. Even so, doctors are expected to diagnose and treat patients in less time and with more restrictions. Medical appointments are so brief that patients can present only one or two complaints at a visit. Few doctors have the time or ability to look at a patient’s whole health picture. Our chronically ill patients are sick, exhausted, in pain, anxious, not sleeping, digesting, or thinking properly.  They have been misdiagnosed or told their problems were “in their heads.” ISEAI aims to help the medical community to better serve these patients.

ISEAI Can Help

If you’re frustrated by the challenges of caring for your complex patients or are unsure how to coordinate the different treatment approaches for environmental toxins, persistent infections such as Lyme disease, and patients’ symptoms such as fatigue, brain fog, pain, and intestinal problems, ISEAI can help.

ISEAI offers the resources to help you to provide effective medical care to chronically ill patients. The ISEAI community of collaborative, open-minded clinicians and scientists will provide training and tools to help you optimize your own blueprint for managing complex patients with environmentally acquired illness (EAI).

“Whether we realize it or not, we are ALL treating diseases that are the results of toxic environmental exposures! ISEAI has been an invaluable resource to collaboratively tackle the difficult terrain of evaluating and treating biotoxin illness and complex chronic disease. We need a village of like minded individuals across many different fields to help solve these monumental public health challenges – ISEAI has created that village! ”

“I am so grateful to have this access to the brain trust that is the ISEAI membership. It’s an invaluable clinical resource. It has been enormously useful to pose questions on the forum to clinicians who have such breadth and depth of experience treating environmentally acquired illness. More very sick patients than ever are now seeking my help and it’s been a blessing be able to consult with such knowledgable and responsive colleagues. I am looking forward to the inaugural conference in Phoenix in May.”
