MIL Update

MIL is having a little visit at the hospital.  Yesterday, while out walking at the mall, she had chest pressure and trouble breathing, enough to make her sit down and stop walking altogether.  She figured it was enough to get checked out - because it's something new and not normal for her.  (Quick background, she had roux-en-Y gastric bypass back in the summer, has lost 100+ lbs. and had previously been dealing with high blood pressure, diabetes, and other obesity-related health issues.)  So, she gets to the ER, her pulse is low - blood pressure normal.  I have no clue as to what this means - and why she's had pain - so she was admitted and is undergoing all the related cardiac testing.  Also, something else, when attempting to draw blood for testing, her blood is very slow to come out and someone mentioned "clotting" on the way out?  I wondered if she may be very dehydrated or something, but I have no medical knowledge... so, that's all I know right now.  I'll update her condition, because of course I'd like to know if this is in any way related to the previous weight loss surgery or complications of, since she's had a few of the complications already.  She feels alright now, but they've kept her for testing further today, and we'll know more later.
