Cardio Activity and Your Heart II

Apart from the technical interpretation, low blood pressure is a sort of disease that saps energy from all parts of your body and mind. Your spirits are down and your body starts shivering. You get a feeling of sinking — and you need a rescue mission immediately!!

Blood pressure is the pressure of blood within the arteries of the body. Blood pressure is the driving force that causes blood to flow through the body from the arteries (where the pressure is high), through organs, and into the veins (where the pressure is low). Blood pressure is generated by the pumping of blood by the heart into the arteries as well as by the resistance to the flow of blood by the arteries. The systolic blood pressure (the top number) represents the pressure in the arteries as the muscle of the heart contracts and pumps blood into the arteries. And the diastolic blood pressure (the bottom number) represents the pressure in the arteries as the muscle of the heart relaxes after it contracts.

Systolic blood pressure for most healthy adults falls between 90 and 120 millimeters of mercury (mm Hg). Normal diastolic blood pressure falls between 60 and 80 mm Hg. (By convention, an individual’s blood pressure is written as systolic/diastolic blood pressure, e.g., 120/80). Current guidelines define normal blood pressure as lower than 120/80. Blood pressures between 120/80 and 140/90, which used to be considered “pre-hypertension,” are now considered too high. High blood pressure increases the risk of developing heart disease, kidney disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke.

When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney, it is referred to as Low Blood Pressure. When this happens, the organs are unable to function normally and can be permanently damaged. It should be noted that unlike high blood pressure, which is defined on the basis of blood pressure alone, low blood pressure is defined primarily by signs and symptoms of low blood flow. In fact, some individuals may have a blood pressure of 90/50 and have no signs or symptoms of low blood pressure, and, therefore, not have low blood pressure while others who normally have a blood pressure of 130/80 may develop symptoms and signs of low blood pressure if their blood pressure drops to 100/60.

There are certain traditional medicines that can help to cure low blood pressure. Butter milk is good for both high and low blood pressure. Using asafetida in various articles of food regularly, also helps to cure low blood pressure.

When someone talks of blood pressure problems, in most cases they refer to issues of high blood pressure. But low blood pressure is also a fairly common condition and it needs attention.

What are the causes of low blood pressure? It turns out there are quite a few of them.

Unearthing the causes of hypotension is important because they have to be dealt with before treating the clinical conditions of low blood pressure.

Anti-hypertensive drugs are one possible cause. If someone with high blood pressure continues to take such drugs without adequate supervision, it can result in a buildup of the drug in the body which can cause blood pressure to drop below acceptable levels.

That is why patients on beta-blockers must be monitored closely to ensure that they do not end up with adverse effects like hypotension.

Diuretic medications can cause this problem if the drugs are overused. In fact, they can lower blood pressure to dangerous levels if not taken correctly.

Cardiac problems can, of course, cause low blood pressure. Problems like tricuspid regurgitation, which is a valve-related issue, can result in the condition.

Traumas such as severe burns can lower blood pressure drastically. Burns affect the permeability of blood vessels which triggers the problem. Heat stroke is another possible cause of lowered pressure because it disrupts the fluid mechanism in the body.

Inflammation to organs like the pancreas may result in hypotension. So can respiratory problems like pneumothorax, as well as dysentery and other severe gastro intestinal problems.

Patients on nitrate medication may have a tendency to suffer from this condition. This is particularly true if they consume alcohol. For this reason, doctors usually advice against alcohol consumption when the patient takes nitrate drugs.

In reality, what constitutes low blood pressure often depends on the patient. There is a fine line between healthy low pressure and clinical hypotension.

As you can see, there are many possible causes of low blood pressure. Your health care giver’s judgment is crucial in deciding if you have hypotension and what treatment it requires.
