First, if a diver knows he's diabetic, does he have an obligation to tell his buddy? Or is it a right to privacy issue and you could be put in an iffy situation by not knowing? What if the stress of handling an emergency has put your buddy in low sugar mode and now 2 people are in danger? Does a dive boat have the right to ask for an additional waver that the diver is aware that his condition may present more complications? My mom and 2 brothers are type 2 - I'm just waiting for my turn. I think that I would have to take a pass when the time comes. That is because my first husband who actually worked as a volunteer on a sheriff's dive team quit when he became insulin dependent- which is the same time he found out he was diabetic- it's not always caught early on. And he loved diving more than anything else in the world- but he wasn't willing to put the rest of the team at risk. Having known 3 people who were all 'in control' of their diabetes (besides my mom or brothers) who all died from complications of shock, or heart etc., I have to say it does happen fast and can come on even without giving a 'not feeling right' warning soon enough. I would want to know if there was someone on the boat or in my buddy team that had an extra risk. Same goes for heart attacks, etc. People who are compromised - do they need to tell or keep it quiet?
