As Health Union has evolved from launching our first community, Migraine.com in 2010, to 19 online health communities and counting today, one thing has remained the same: bigger has to mean better. Serving the needs of people impacted by chronic health conditions and reaching more than 10,000,000 people each month yields a unique opportunity not only to understand the challenges associated with a specific chronic condition but also to gain a clear understanding of the bigger picture surrounding the full scale of a person’s challenges. In many cases, this includes experience with co-morbid conditions.
