Hard science has uncovered a mechanism whereby the same collagen abnormalities in EDS that make joints especially flexible seem to affect blood vessels, making those with it prone to accumulation of blood in the veins of the legs, an effect that may lead to exaggerated cardiovascular responses to maintain the output of blood from the heart. This and other foibles, which I feel are versions of the same response, put those of us with this issue under immense pressure and strain, all the time, as our version of "normal" so just imagine how much we then react to any additional triggers, to which we tend to be hypersensitive (I share my about theory about that too...), setting off our nervous system at regular intervals in a way that has nothing inherently to do with mental health...although, no surprise, it can start to manifest as anxiety over time. Joining some dots and celebrating just how much people with hypermobility type EDS deal with as their daily benchmark...plus some practical ways of making it better.
