By the following definition, you are within normal limits and should not be concerned. Read on:

In most healthy people, blood pressure remains above 90/60 (or, 90 over 60). However, blood pressure varies from person to person; what is considered borderline low for one person may be normal for another.
Chronic low blood pressure is almost never serious. But health problems occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. It most commonly occurs in someone who's rising from a prone or sitting position to a standing position. In such cases, it is known as postural hypotension, orthostatic hypotension or neurally mediated orthostatic hypotension. Clinically, postural hypotension is defined as a 20mm Hg–reduction in systolic blood pressure or a 10mm Hg–reduction in diastolic blood pressure within three minutes of standing.
Postural hypotension is considered a failure of the autonomic nervous system -- the part of the nervous system that controls involuntary vital actions, such as the heartbeat -- to react appropriately to sudden changes. When you stand up, some blood pools in your lower extremities. Uncorrected, this would cause your blood pressure to fall. However, normally your body compensates by sending messages to your heart to beat faster and to your blood vessels to constrict. This offsets the drop in blood pressure. If this does not happen, or happens too slowly, postural hypotension results.
The incidence of both low and high blood pressure normally increases with age, due in part to normal physiologic changes. In addition, blood flow in the brain declines with age, often as a result of plaque buildup in blood vessels. So the prevalence of postural hypotension also increases with age; an estimated 10 percent to 20 percent of elderly people have postural hypotension.
Symptoms of postural hypotension include:
Dizziness
Lightheadedness
Unsteadiness
Dimming or blurring of vision
Weakness
Fatigue
Cognitive impairment
Nausea
Head or neck discomfort
Postural hypotension, particularly in the elderly, may increase the risk of falls, leading to the potential for bone fractures and other injuries.

You should exercise MODERATELY (like walking) during induction.... don't start any vigorous program until after.
Hope that helps! |
