Dermatitis herpetiformis can be very itchy and is a rash that can also include water blisters. They are often on elbows, butt, knees, waist and back. They will scab but you will probably get new spots as well. Unfortunately, it is chronic though DH - dermatitis herpetiformis can be controlled via nutrition according to some. It’s an allergy to gluten so you need to be fastidious in your eating to keep it away.

Cut back on iodine as that is important to get the rash going. Yes this means chips but also our diets are generally high in iodine. There are salt substitutes available in health food stores and supermarkets.

Some people with this may also have celiac disease but not necessarily. Gse can be separate from dermatitis herpetiformis. To stay away from gluten means be very careful of restraurant food as well plus items you may not even think of. There is also a medication called dapsone that is quite effective. Due to side effects, some people prefer the gluten free route and this has to be a personal decision. Dapsone users need to take regular blood tests to monitor the effects on the body.
