I suppose the people I knew were exactly the opposite.

They actually used to play the severity of their diabetes down, then when they had a hypo at work all hell used to break loose, because in a lot of cases the employer really didn't know what was going on.

For some people, the problems it causes and the subsequent stigma that is attached to it, makes them hide it. A catch22 really, because eventually it did come out and a lot of them used to lose their jobs because they didn't declare it in the first place.
