How rare is dermatographia? It is a question many of us have asked once we find out that our annoying itching and redness is actually a medical condition. However, getting the best information is harder than you might think.
According to the Mayo Clinic, dermatographia affects 5% of people worldwide. However, I feel like the number is higher based on scientific data I have seen. If you look at a 15-year trend line based on Google trends, you will see that searches have doubled or tripled each year over the last 10 years or so. There are now Reddit pages and Pinterest boards, all specifically focused on dermatographia.
If you look at the searches related to skin itching and inflammation that happen every day online, combined with the trends globally, it is clear that dermatographia is no longer a “rare” condition. After all, the word rare means highly uncommon, sparse, and infrequent.
