The Lactose Intolerance Clearinghouse Has Moved.

My old website can be found at I am no longer updating the site, so there will be dead links. The static information provided by me is still sound.

For quick offline reference, you can purchase Planet Lactose: The Best of the Blog as an ebook on or or or a whole lot of other places that Smashwords is suppose to distribute the book to. Almost 100,000 words on LI, allergies, milk products, milk-free products, and the genetics of intolerance, along with large helpings of the weirdness that is the Net.

I suffer the universal malady of spam and adbots, so I moderate comments here. That may mean you'll see a long lag before I remember to check the site and approve them. Despite the gap, you'll always get your say. I read every single one, and every legitimate one gets posted.

Report from the LI Conference, part 7

The sensitivity of our insides means that diarrhea is a symptom of about a zillion causes. Some of them may be food related, some may be from diseases. If you go a doctor, he or she has to sort through your entire pattern of symptoms to make a proper diagnosis.

Clinical Presentation and Approach: But What if It Is Not Lactose Intolerance?

Dr. Chang had a handy chart to show the common disorders that can be confused with or for lactose intolerance.

That's not six disorders. That's six entire classes of disorders that have to be sorted through.

I don't diagnose people myself, but it's apparent that many of those who write to me don't have lactose intolerance but something else entirely. It's the doctor's job to figure out what, but you can see that's not always the easiest decision to make.
