Sometimes, it can take a day of disaster to help people with diabetes to realize they need to be more communicative with those around them about the possibility of hypoglycemia.

That was the case for “Dr. P”, a diabetes blogger and English professor who runs the website Diagnosednotdefeated.com. Dr. P, who prefers to go by a pseudonym because she hasn’t told her co-workers about her condition, had a hypoglycemic event that ruined a day of sightseeing in Normandy, France. She hadn’t wanted to tell her traveling companions she was feeling off in Normandy, and events spiraled out of control.
