Ectodermal dysplasia arthrogryposis diabetes mellitus is a rare genetic condition that affects a person’s hair, skin, teeth, and sweat glands, along with them having diabetes. People with ectodermal dysplasia are usually born with wiry, brittle, and pale hair with milky white nails. Their skin is often dry, wrinkled, and darker in color around their joints. People with ectodermal dysplasia usually have missing teeth, or teeth that are small and pointed. Their sweat glands may not work like other peoples causing them to easily overheat. This is because they cannot sweat like other people, and therefore cannot cool off the same way. In diabetes mellitus, an individual is unable to produce insulin, which is the chemical messenger which helps the body to breakdown sugars. Symptoms of diabetes mellitus include frequent urination, increased thirst, dry mouth, increased hunger, fatigue, and weight loss. Treatment for diabetes mellitus typically includes a daily regimen of insulin injections. Talk with your doctor to find the best treatment for you if you have been diagnosed with ectodermal dysplasia arthrogryposis diabetes mellitusis.
