For the past 3 weeks my husband has been experiencing extra low blood pressure (e.g. 73/48, 88/67 and this am 72/28.) The highest reading for the last week was 112/64 with most of the other readings in the 90s. The past two days the lower reading keeps dropping. For the past 1-1/2 mos. he has had some problem with diarreah(sp). He has been both to the ER and to his doctor. They told him he was dehydrated and advised to drink lots of Gatorade. He had congestive heart failure in 1998, but the heart doctor has been pleased with his recovery and his EF is now almost normal. He does take various heart medicines and only occasionally(like once a year) had trouble with low blood pressure. He is scheduled for his semi-annual visit to the heart doctor the end of this month. My question is: Other than the risk of fainting and falling, what other risks could be involved with this low blood pressure problem? He is 74 years old, 6'1" 145lb
