What causes a 50 point drop in blood pressure in diabetic patients? -

My uncle was taken to the hospital for a spike in his bp (he is currently being treated for hypertension) on Friday. {He is diabetic and has also suffered a heart attack in the past 2 years.} His bp was high all weekend and they finally got it down last night and were going to release him today and suddenly it dropped to 85/53. Anyone know what this may possibly be a sign of? Any help at all would be much appreciated. Thank you!

The diabetes in and of itself doesn t cause BP fluctuations. Having diabetes over time does greatly increase the risk of heart attack, stroke, and other cardiovascular events, so perhaps it was a stroke, and the stroke caused the dip in BP? Fluctuating BP is caused by a number of things, but not diabetes per se.
