When we’re talking about the term in a medical sense, it means when an additional disease or disorder is present at the same time as another. This is important because many in the medical world are taught to look for a single underlying cause. Think to many of the episodes of the TV series House. “She has low blood pressure, elevated white blood cells, seizures, migraines….what is the one cause?” But EDS patients aren’t your run of the mill patients and we come with quite the laundry list of cormorbid conditions.

Why Is This Important?

Awareness is one of the greatest tools in your arsenal. The more we are aware of potential problems, the more we can hopefully catch them before they progress. This is also important because EDS patients can’t safely take the approach of “one core cause” when it comes to our health. We must treat each individual illness that may decide to tag along with that base diagnosis of EDS.

It is so important thatThe Ehlers-Danlos Society even has a whole Coalition of physicians dedicated to researching cormorbids! EDS is so much more than being hypermobile or flexible, it means a whole range of potential problems that we face every day throughout our lives.

Unofficial List of Comorbidities Associated with EDS

The bulk of this list is from the wonderful site Oh Twist!, though I’ve added just a few that I’ve seen within the community. Please make sure to check out their site as there’s a lot of really wonderful information there so we can support others in the Dazzle! Please keep in mind that this list is not the official list of comorbidity conditions, they are a list that has been gathered from members within the EDS community and is not meant to be used as a diagnostic criteria.
