Looks like we missed this one:
"What if everybody in the world farted at the same time?"
We were all supposed to fart at 4 PM Pacific time today. Oops. I forgot.
I was given a gift a few months ago by a family with several young children: The Gas We Pass. It's a very funny book. Perfect for the waiting room.
Lactose intolerance is probably the most common cause of frequent farting:
Between 30 and 50 million Americans are lactose intolerant. Certain ethnic and racial populations are more widely affected than others. As many as 75 percent of all African Americans and American Indians and 90 percent of Asian Americans are lactose intolerant. The condition is least common among persons of northern European descent.
Here's a nice patient handout on Lactose Intolerance. Patients have usually heard of lactaid, but I usually make sure that they know that they don't need to spend $8.00 for lactase. Wal-Mart, CVS and several of our local supermarkets carry generic versions of lactase for much less.
