Well, there are thirteen different types of EDS (most of them are REALLY rare, though), based on which connective tissue they impact the most. The most common are hypermobile, classical, and vascular. I have the hypermobile type, which mostly impacts joints. Classical EDS can have skin issues, and vascular is the type where it can cause your blood vessels to rip open inside of you. hEDS is the least likely to kill you, but most likely to negative impact your quality of life.
