Low Diastolic Blood Pressure
Blood pressure refers to the pressure that blood exerts against artery walls as it flows. The causes of hypertension are not as clearly understood and known as the causes of low blood pressure. In as much as the causes of hypotension are known, doctor diagnosis is essentially dependent on the manifestation of specific known symptoms of low blood pressure.
Digital blood pressure equipment such as the Omron blood pressure monitors [pictured] and many such others display two figures when measuring blood pressure. The bigger top number (120mm Hg) is the systolic blood pressure and the bottom smaller number (80mm Hg) is the diastolic pressure reading. As a matter of observed pattern, both these readings change overtime with systolic pressure shown to raise right through the life of an individual.
In the case of malignant hypertension a specific hypertension subtype, systolic and diastolic blood pressure are excessively high to the damaging of arteries and internal organs. The pattern mentioned above also shows that diastolic blood pressure has a tendency to raise until about 50 years old or midlife in general before leveling off. Thereafter if falls.
In general the elder members of society have the problem of a falling diastolic blood pressure broadening the gap between systolic and diastolic blood pressure readings. This gap is known as the pulse rate which doctors use to access risk of heart attack, stroke and heart disease as it continues to widen.
The forgoing makes it a correct conclusion to say low diastolic pressure is essentially associated with old age and more prevalent in the older members of society. Left to continue falling, low diastolic pressure will lead to death as a result of occurrences of stroke, heart failure, kidney failure and heart attack.
Low diastolic blood pressure causes
The causes of low diastolic pressure mainly relate to the natural causes of age. Age naturally results in the stiffening of the aorta which causes less blood to be available to facilitate diastolic blood pressure at the relaxation of heart muscles during the pumping work of the heart. When heart muscles contract they create systolic blood pressure. When they relax they create diastolic blood pressure. Low diastolic pressure may also be as a result of ant-hypertensive therapy especially when trying to lower high systolic blood pressure. This is however uncommon yet possible.
The elderly have particularly a double challenge of dealing with isolated systolic blood pressure and a falling diastolic blood pressure. Usually stabilizing diastolic pressure during hypertension treatment is much easier than high systolic blood pressure. Doctors will aim to bring a low diastolic blood pressure up to about 90mm Hg whilst at the same time being careful to avoid pushing systolic blood pressure up any further.
Specific hypertension medications will achieve this goal guided by specific hypertension guidelines a standard in the world of hypertension management. The use of other natural remedies especially to do with lifestyle modifications such as following a hypertension dietwill also become necessary depending on how a doctor leads the patient.
Low diastolic blood pressure symptoms will include the development of cardiovascular disease or at least increased risk when diastolic blood pressure is lowered to below 70mm Hg. Patients who reach diastolic blood pressure levels of 55-60mm Hg during isolated systolic hypertension need accompanying treatment of other possible cardiovascular risk factors.
Low diastolic blood pressure during pregnancy may occur during the middle of the pregnancy at which point both systolic and diastolic pressure will reach its lowest point. Pregnant women will suffer symptoms of low blood pressure which will including feeling dizzy, lightheaded and weak. Under a doctor's guidance a diet rich in salt will be required until blood pressure comes up again. Drinking lost of fluids will also improve the situation as increased volume of fluids in the blood also raises blood pressure levels.
