Hi there. Newly-registered reformed lurker here. ;)
I've suffered from Geographic Tongue, or benign migratory glossitis if you prefer fancier sounding terms for yucky but ultimately harmless conditions (according to conventional wisdom) for as long as I can remember.
After approximately 2-3 months eating Paleo, the condition has completely resolved itself.
Now, while I'm not entirely surprised by this, I wondered if anyone else has had a similar experience, or can shed any light on the whys and wherefores?
Well, check out the "cause" section on wikipedia: http://en.wikipedia.org/wiki/Geographic_tongue
They even link it to a correlation with celiac disease. This shows up time and time again in the paleo literature: many seemingly unrelated diseases (Type I diabetes, eczema, rheumatoid arthritis, and so on) show up more in people with celiac than without.
My interpretation of this is that there's a third thing (gluten) that's the core cause of all of this. In some people gluten may cause only one of those things (T1 diabetes, for example) or it may cause many of them.
So it makes complete sense to me that paleo has cured this for you.
Side note: if anyone has anything wrong with them that often shows up correlated with anything that paleo is known to cure, I bet that paleo could cure that other thing two because it's probably fixing the underlying cause not the symptoms.
Mine hasn't gone away after 1 year paleo. It my case it's hereditary, my mom had it, I have it, and one of my daughters. All three of us have a genetic syndrome, and it seems to be very common in people with this syndrome, as well.
It doesn't bother us until we've eaten a certain amount of acidic food, and then all of the sudden it becomes painful.
That and when my daughter's preschool had an outbreak of hand, foot mouth disease (which she had as an infant) they wanted to send her home because they thought she had "lesions" on her tongue.
When I strictly follow a grain free diet, my geographic tongue (which I've suffered from since childhood) clears up completely. When I go back to grains, It comes back again like a house afire. Must be a connection.
After 18 months of living a Paleo lifestyle, I'm doing a 6-week gluten challenge in prep for my endoscopy to check for Celiac. I've definitely had more geographic tongue flare-ups since reintroducing gluten. Came across this articlelink text
