What if Sleep Apena goes untreated? Can it cause low blood pressure?

It actually causes *high* blood pressure. Also heart disease and apparently diabetes. It's really no big deal to have a sleep study--I've done it. You go in and they hook you up to machines and you sleep. If you have apnea, you go back again and try it again, but this time with a breathing mask. The masks feel weird at first, but you get used to it. It's better than having heart problems!
