Doctors just don’t know enough about the long term issues faced by those who are born with Ea and TEF. This is why this survey was created.  The first ever world survey for Ea and TEF.


With the long term issues faced by those who are born this way being so uncertain, please share this survey with ANYONE. Even those not affected can forward this to help children and adults survive. The survey will provide vital information for doctors worldwide to help them treat our babies and help them survive.

So please share this and get your friends to share it too. I don’t want my son or anyone else’s son or daughter to die as a result of doctors just not knowing how to treat them.
