FROM OUR EXPERTS
Over the last few weeks we’ve been focusing on high blood pressure and the difficulties this can cause. But, having low blood pressure, or hypotension, can also be problematic.
A normal blood pressure reading is usually in the range of 120/80 (systolic/diastolic); low blood pressure is less than 90/60.
If you’re an athlete, low blood pressure is usually a sign of good cardiovascular health. But, in the elderly for example, it may be a sign of an underlying problem. Low blood pressure is however, only a medical concern if it causes signs or symptoms, such as dizziness, fainting, or in extreme cases, shock.
Some of the causes of low blood pressure include:
Acute illnesses which leads to severe blood loss or damage to the heart
Diseases involving the nerves controlling the veins in the legs
Hormonal problems such as an underactive thyroid, overactive thyroid, or diabetes
Loss of blood, or loss of fluid
Low or high body temperature
I suffer form Migraines during my menstruation. Sometimes my blood pressure rises 160's and 90's for about 20 minutes followed by shivers and then it goes down. Normally my blood pressure tends to be on the low side 110/70. Can a migraine cause temporary high blood pressure? Veronica.
Yes, Migraine can cause blood pressure to rise. Please be sure that your doctor is aware of this.
Good luck, John Claude Krusz and Teri Robert

Today I would like to review some of the primary causes of High Blood Pressure .
In most cases, there is no clear cause of high blood pressure. The term “essential hypertension” is used in these instances. Doctors can often treat the high blood pressure but never cure it. However, there are some causes of high blood pressure which can not only be treated, but also be cured.
The body sometimes needs to increase blood pressure to maintain adequate flow of blood to the brain and other vital organs. For example, if the kidneys sense a decrease in blood flow they assume it is due to low blood pressure. The kidneys then produce a hormone to elevate the blood pressure. In reality, the cause of decreased blood flow may have nothing to do with low blood pressure at all. A blockage in the pipes through which the blood is delivered to the kidneys (renal arteries) may cause less blood. The kidneys may thus raise blood pressure unnecessarily. This type of high blood pressure is difficult to treat...
