Hi...My mom has had 3 falls in the past 1 1/2 mos. The first we attributed to her tripping on a rug but now we are not so sure that happened. She fell in the bathroom getting up off the toilet and fell getting off of a chair. She has no warning. She says she does nto lose consciousness but we think she may for a second or two before realizing that she is falling. The last fall she hit her head and shattered a window. We are seeing a cardio this week. She does not take medication. Her carotid artery was 82% blocked last year and cardio said to wait till its 90%. Could a clog carotid cause this? Also her blood pressure taken in succession was lying 160/80 sitting on end of bed 145/80 and then standing 132/72. A quick decrease in bp. any thoughts?
