Comorbidity is a medical term that you may have heard your doctor use. It describes the existence of more than one disease or condition within your body at the same time. Comorbidities are usually long-term, or chronic. They may or may not interact with each other. Below we have compiled pages on some of the most common comorbid conditions for Ehlers-Danlos Syndrome. This is not a complete list, and more will be added over time as we compile the information.

Each page contains information about the condition as well as links to official charities and foundations for each condition. We have also added links to New Zealand Aotearoa charities, organisations and support groups where applicable.
