cause of low diastolic blood pressure
ANSWER: Two circumstances typically can result in extremely low diastolic blood pressure. The condition may be associated with severe hypotension, or it could be caused by profoundly stiff arteries that occur due to aging, diabetes or fatty buildup in the arteries (atherosclerosis).
Heart Problems. MayoClinic.com says that low blood pressure can be caused by a number of heart problems or defects. A low heart rate, also known as bradycardia, can cause a drop in blood pressure. Diastolic pressure can also be affected by heart valve problems, a heart attack or heart failure. In these situations, the heart cannot circulate the amount of blood that is needed.
