Low diastolic blood pressure can indicate heart problems, endocrine problems, dehydration, Allergies, blood loss, infection, or pregnancy. It can cause dizziness and fainting.
When a blood vessel (like an elastic pipe) is empty there is no pressure on its wall. When there is blood flowing in a blood vessel it exerts pressure on the walls of the blood vessel (pipe). This is the basal pressure called the Diastolic pressure (The lower of the two numbers). When the heart pumps blood it drives the blood with force and this exerts higher pressure on the walls of the blood vessel. This is called the Systolic pressure, the higher number in the blood pressure measurement. Thus, Blood Pressure of 120/70 means the systolic pressure is 120 and the diastolic pressure is 70.
A dogs normal blood pressure is 140mm systolic, 100 mean, and 75mm Diastolic. Just like in humans pets that are overweight or on poor diet can suffer from high blood pressure.
Use a blood pressure cuff (sphygonometer, or something). The reading will be something like 120/90 where the higher number is the pressure of the heartbeat (systolic) and the lower number is the pressure between beats (diastolic).
If you are wondering what blood pressure is measured in its Millimeters of Mercury or mmHg cubed. Looks like this 120/80 mmHg
Normal blood pressure is 120/80 mm Hg . The ranges being 90-140mmHg systolic(top number)(peak heart contraction pressure) and 60-90 diastolic (botom number)(heart relaxed pressure). A persistently high blood pressure over 140/90 is diagnosed as Hypertension. The two numbers indicate your systolic and diastolic pressure. Systolic (the first number) indicates the pressure exerted when your heart contracts to pump out blood. Diastolic (second number) indicates the pressure exerted when your heart muscles relax. Normal blood pressure is 120/ 80 mm Hg. But everyone knows that pressure does not remain at that normal level throughout the day. It can go high or low depending on many factors such as activity, stress, after meals, etc. Normal fluctuations for systolic pressure range from 100 to 140 and for diastolic from 60 to 90. You should check with a doctor about your diastolic pressure since it is close to being below normal range. Ask your doctor whether it is advisable to take blood pressure supplements like Blood Pressure Matrix which consist of a blend of nutrients like Vitamin D, Folic acid, Potassium citrate, hawthorn leaves, taurine and natto-kinase. These nutritionally support the body's natural ability to regulate normal blood pressure.
The top number in the blood pressure fraction is the Systolic pressure, or the amount of pressure put on the walls of the arteries during the contraction and ejection of blood from the left ventricle. The bottom number is called the Diastolic Pressure and it means the lowest pressure in an artery in the moments between beats when your heart is resting.
Blood pressure at or above 140/90 is considered high blood pressure. Conversely, pressures below 100/60 (or in some cases, 90/60) are considered low blood pressure.
Hypertension- high blood pressure. (Hypotension- low blood pressure) High blood pressure is the pressure that is placed in your arteries when the heart pumps your blood. High blood pressure is an above average pressure that could eventually lead to things like strokes or heart attacks. Blood pressure is broke down by systolic and diastolic. Systolic readings are normally the higher of the two pressures when getting your blood pressure taken. If your systolic is lower than your diastolic then you probably aren't reading this and maybe in the hospital or even dead. Diastolic is the pressure left over in the arterie after the heart refills for another pump. Giving you a lower reading. Normal blood pressure should range around 140/80. If it is higher than that it would be a good idea to start an exercise program and diet.
The best place to get a low blood pressure chart would be from your doctor. The charts are very general, and your doctor will be able to tell you how well it fits you based on your specific health factors.
Blood pressure of 140/73 might not require medication, but it does require some attention. Some simple lifestyle alterations, such as a minor change to your diet, or slightly adjusting your exercise routine could be all you need. Run "high blood pressure" through your favourite search engine. You'll come up with plenty of information. Check your blood pressure regularly at one of those machines you often see in drug stores, and have your doctor check it a few times a year as well.
Abnormally high blood pressure is called "Hypertension" (Hyper-= above, over, or excess; Tension= to strain or stretch)In essence blood pressure is the force(stretch or strain) on the blood vessels' walls. Thus abnormally high blood pressure would be an excess strain on the vessels' walls.
As we age, our arteries lose the elasticity that allows the systolic/diastolic to be within the norms. Without that flexibility, the differences between systolic & diastolic will be greater. Such as the diastolic will decrease. The normal upper limit of pulse pressure is 60 mm. In example: 120/80 would be only 40. Well within. With hardening of the arteries, the difference might be something like 120/50-60, and so forth. This explains the differences between age groups. Different genders don't make any difference.
