“Low blood pressure” means many serious problems, let us see what are all involved with our blood & its pressures
The force exerted by blood circulation on the blood vessels’ walls is known as ‘Blood Pressure’. This is the most important side of our body’s sign system or can be said as the vital signs of our body-systems.
Our body signs or the vital signs of our body-systems
The signs of our body system are breathing, heart rate and body temperature.
Generation of blood pressure
Heart pumps blood throughout our body by taking the routes of the arteries. The process is fully dependent on the responses of the arteries flowing of blood. This process is known as ‘blood pressure generation’.
How blood pressure is expressed?
Blood pressure is expressed through the terms 1) systolic and 2) diastolic blood pressure.
The systolic blood pressure or high blood pressure
The top number or systolic blood pressure is 120/80 that is the pressure generated in the arteries.
The characteristics of the system: Some pressures are exerted by our heart through arteries, which results in contractions of the heart and pumping blood into them. Systolic blood pressure means the heart is pumping blood.
The diastolic blood pressure or low blood pressure
The bottom number or the diastolic blood pressure is the pressure in the arteries due to the relaxation of the heart muscles following a contraction.

The characteristics of the system: Diastolic blood pressure means the heart is relaxing after pumping blood to the arteries.
Low blood pressure
Low blood pressure becomes so low that it causes some signs and symptoms; the reason being the low blood flow to the veins and arteries. If the blood flow is too low to carry required nutrients and oxygen to the important organs like kidney, heart and brain, the organs will fail to function properly, which in turn will either permanently or temporarily damage the organs.
Signs and symbols are the main specifications for measuring low blood pressure
Unlike the measurement of high blood pressure, low blood pressure is measured by the signs and symbols. Although 90/50 blood pressure number is considered as the low blood pressure, but many normal persons have continuous blood pressure reading as 90/50 without any symptoms, proving that they do not have the problem of low blood pressure. But the irony of the fact is those who have high blood pressure, may also develop the signs and symptoms of low blood pressure, in case there blood pressure drops down to 100/60.
Normally, pregnant women may experience decreased blood pressure during their gestation period. In some cases, the blood pressure may go down below 100/60. Hence it is always advised that a pregnant woman must be constantly under the observation of an obstetrician.
Generation of blood pressure
During diastole or the relaxation of the heart, the blood from the heart gets filled in the left ventricles. In this position, the left ventricle not only contracts but also pumps blood to the systole or arteries. During contraction of the systolic pressure or of the ventricle, the blood pressure in the arteries is higher; the reason is active ejection of blood in the arteriesIn most of the cases, elderly people are the victims of this condition.
8) Syndrome of Sick sinus means failure of generation of electrical signal by the heart’s electrical system for maintaining normal heart rate. (Fast is the criteria).
9) Heart block is the result of the blockage in the specialized tissues which are responsible for transmitting electrical current to the heart. The problem is due to degeneration from medications, atherosclerosis and heart attacks. In case of heart block, all or sometimes some of the electrical signals are prevented by the heart blockage. In this condition, the normal contraction of heart gets disturbed.
10) Drug abuse or toxicity of drug. The examples are beta blockers or Lanoxin (digoxin) , used for treating high blood pressure can cause the slowing down of the electricity transmission to the heart due to chemical reaction that lead to hypo-tension or bradycardia
11) In case of tachycardia which is known as abnormality in the heart rate’s fastness. This condition can be responsible for low blood pressures. Atrial fibrillation is known to be the most common example of tachycardia. The disease atrial fibrillation is heart disorder. The characteristics of which are irregular and rapid electrical discharges from the heart muscle, causing contractions in the ventricles’ electrical discharges in an irregular and rapid way. This is a usual condition. Because of rapid contraction of ventricles, maximum filling of blood dos not happen. Other than this, even with faster contraction (due to the faster heart rate), the amount or volume of blood which was to be pumped gets decreased. Ventricular tachycardia is the other type of disorder due to abnormal heart rhythms, which can cause low blood pressure. Some of the patients get life threatening shocks.
Your overall health and low blood pressure
Low blood pressure means lower risks of heart disease, kidney disease and strokes. People with low blood pressure are the people who have the ideal body weight, people who exercise in regular way, athletes and non-smokers. Low blood pressure is not alarming as long as it does not become too low to cause symptoms and become the cause for organ damages.
