The exact cause of dermatitis herpetiformis is not fully understood, but it is believed to be related to gluten intolerance. The following are some of the most common triggers for dermatitis herpetiformis:
- Gluten: The consumption of gluten, a protein found in wheat, barley, and rye, is one of the most common triggers for dermatitis herpetiformis. When people with this condition eat gluten, it can cause an autoimmune reaction that triggers skin inflammation and blistering.
- Stress: Stress can trigger outbreaks of dermatitis herpetiformis in some people.
- Hormonal changes: Hormonal changes, such as those that occur during puberty, pregnancy, or menopause, can trigger outbreaks of dermatitis herpetiformis in some people.
- Certain medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), can trigger outbreaks of dermatitis herpetiformis.
- Skin injuries: Trauma to the skin, such as cuts or abrasions, can trigger outbreaks of dermatitis herpetiformis.
- Environmental factors: Exposure to environmental irritants, such as harsh soaps, detergents, or chemicals, can trigger outbreaks of dermatitis herpetiformis.
It is important to note that triggers can vary from person to person, and what triggers an outbreak in one person may not trigger an outbreak in another. Keeping a journal of triggers and symptoms can help you identify what triggers your outbreaks and avoid them in the future.
