Low Blood Pressure Chart

Considering low blood pressure chart in context of women, for men, during pregnancy and by age

Low blood pressure is defined as blood pressure that is below the normal expected for a person in a given environment. You may look at the blood pressure definition for a broader definition of blood pressure. The following low blood pressure chart is applicable to adult men and women. This is because both adult male and females are expected to have a similar normal blood pressure on average of 120/80mmHg.

This chart in discussion here may not be efficiently applicable on children because infants and children specifically have significantly lower blood pressure compared to adult men and women.

High blood pressure which is also known as hypertension is often presented with the aid of a high blood pressure chart showing the various stages of hypertension congruent with particular blood pressure numbers. Several challenges present when attempting to do the same for low blood pressure in the form of a low blood pressure chart.



Chief amongst these challenges is the widely agreed and understood relativity of a low blood pressure condition. The chart above summarizes known data of low blood pressure readings in some individuals and accompanying symptoms of low blood pressure.

Unlike high blood pressure, low blood pressure diagnosis relies to a very large extent on presentation of symptoms and signs of low blood pressure. In most cases when there are no symptoms showing of low blood pressure doctors simply put the concerned patient under observation.

At the top of the low blood pressure table above is the normal blood pressure reading values of 120/80mmHg. When blood pressure readings begin to fall as shown in the chart for low blood pressure they reach a reading of 100/60mmHg called a low normal. There are various reasons for low blood pressure readings in men and women. Causes of low blood pressure will include pregnancy for women and dehydration and loss of fluids even through vomiting or diarrhea. Heat and allergic reactions are also known causes of low blood pressure.

In particular allergic reactions are known to cause deadly sharp drops in blood pressure to very low levels. Blood pressure medication side effects such as that of diuretics for high blood pressure can also cause very low blood pressure readings. This can also be in the form of low diastolic reading.

As shown in the low blood pressure chart above, a low blood pressure reading of 100/60mmHg can be normal for children and athletes. In particular, athletes are known to have relatively low blood pressure than the rest of the population. However this does not suggest anything negative about their health.

The chart for blood pressure illustrated above confirms what is generally agreed amongst doctors that a low blood pressure reading of 90/60mmHg marks the setting in of hypotension. This is however, as mentioned highly relative. A reading of 90/60mmHg is of greater concern in an individual who usually has higher blood pressure numbers. It is less worrying when it happens in an person who has chronic low blood pressure with no symptoms.

Blood pressure can continue to fall from a reading of 90/60mmHg until signs of low blood pressure shown in the chart start showing. Typically blood pressure can fall to low levels due to sickness or an emergency such as blood loss. Were there has been massive blood loss, blood pressure can rapidly fall as shown in the low blood pressure chart to a point of coma and death.

When blood pressure continues to fall and symptoms are showing and there is no remedy administered, a patient may suffer shock which is the complete shut down of major organs leading to death. Dizziness and confusion in a patient of low blood pressure such as a pregnant woman is as result of lack of oxygen to the brain.
