352: Dermatitis Herpetiformis (Celiac Gluten Rash) Symptoms + Treatment w/ Dr. Peter Lio

Are you struggling with a super itchy skin rash that looks like eczema? If gluten seems to be a trigger – you might be dealing with dermatitis herpetiformis!Dermatitis herpetiformis (DH) is a rare skin rash that starts off as incredibly itchy, small blisters that eventually start to become open sores due to constant scratching.This rash is generally considered to be MORE ITCHY than eczema, and is commonly found in the creases of elbows, knees, and buttocks.What causes DH, you might ask? The answer is surprising: Gluten. Yes, dermatitis herpetiformis is a gluten rash – the skin manifestation of celiac disease. In fact, eliminating gluten from your diet and skincare is necessary to find relief.Joining me to talk about the link between gluten, dermatitis herpetiformis, and celiac disease is fan-favorite guest Dr. Peter Lio, who is a Clinical Assistant Professor of Dermatology & Pediatrics at Northwestern University Feinberg School of Medicine.He received his medical degree from Harvard Medical School, completed his internship in Pediatrics at Boston Children’s Hospital, and his Dermatology training at Harvard where he served as Chief Resident in Dermatology.

They can be going nuts where they're scratching. And again, it's these funny areas, elbows, knees, buttocks, and they're so uncomfortable. They can't really seem to get to the itch. I find it's even more intense and deeper in general than atopic dermatitis.”LinksFind Dr. Lio online | Twitter | FacebookHealthy Skin Show ep. 216: Could Your Rash Be A Sign Of Lymphoma? w/ Dr. Peter LioHealthy Skin Show ep. 246: Everything You Need To Know About Skin Tests (Done By Your Dermatologist) w/ Dr. Peter LioHealthy Skin Show ep. 275: Why You're So Itchy (HINT: It's Probably Not Histamine) w/ Dr. Shawn KwatraDermatitis Herpetiformis (NIDDK)Dermatitis Herpetiformis (NIH)Dermatitis Herpetiformis: Novel Perspectives
