[IP] scuba and the pump

Oh boy... what a miserable experience.  Vertigo could happen to anyone, 
but being diabetic, there are many things that you'll have to be 
particularly careful about when diving.  The first couple of times out, 
you might want to stay fairly close to the surface just so that you can 
check yourself periodically.  The exercise, and the the exposure could 
keep your BG running low, but the adrenaline, and pressure changes may 
well elevate your BG.  After a few times out, you'll have a better idea.  
Some things that might help...

1) Your infusion site will probably come out if you're soaking for over 
an hour.  Most adhesives just won't hold that long.  Make sure that you 
bring an extra set along as well as syringes in case you need insulin 
but aren't ready to get out of the water yet.

2) If you tend to get low during a dive make sure to eat a high protein 
meal before diving.  Although this would not be recommended to a 
non-diabetic... in your case it is mandatory in order to keep your BG 
levels up.  Also... take along some of those sealed gel-glucose packs.  
The tablets won't take the moisture of a dive, but you might just need 
some sugar FAST.  Remember that on dives (particularly deep dives) the 
change in pressure and the sluggish feeling that the water can leave you 
with may mask signs of a low BG.  By the time you feel low... you might 
be too low to make it back to the boat.

3)  If you tend to get high during a dive, you might want to try eating 
(once again) a high protein meal before the dive, and bolusing with 
regular insulin rather than humalog via a syringe.  The regular will 
stay in your system longer and in combination with the rigorous workout 
of diving, this will probably prevent you BG from rising too far.

4) YMMV.  There are so many different factors, that it can be difficult 
(but not impossible) to predict how you will react.  Take it slowly 
until you realize how you are reacting to this new activity.

5)  MOST IMPORTANT!!!!!!  Make sure that your dive partner has a good 
understanding of your diabetes and how to react if something goes wrong.  
You don't need some moron giving you an injection of insulin if you wind 
up unconscious due to low BG.  People will panic if you start acting a 
little odd... especially under the water.  You need someone who can 
think clearly and react appropriately.

6) Have fun.  Hope you enjoy diving.
