Which Diseases/Conditions Are Connected?

I was disappointed that the connection list didn't include either stroke or heart disease, or CV - cardiovascular. But look for connections to your other diseases/conditions. It doesn't look like they covered any brain problems; Alzheimers, Huntingtons, Parkinsons

Do you suffer from asthma as well as allergies? Is your insomnia coupled with chronic pain? It turns out that two (or more) is company when it comes to diseases and symptoms. But which conditions are most strongly connected to each other?

This graph shows connections* between conditions reported by members of CureTogether, a free resource for patients to share information about diseases and treatments. Connections are only shown if they are stronger than would be expected by chance based on how common the two conditions are.
