Normal blood pressure falls in the range of 90/60 mm Hg to 130/80 mm Hg.

Your blood is termed as low blood pressure when your systolic pressure and diastolic pressure are lower than the normal levels. It is possible that some individuals may have blood pressure levels at 90/50 mm Hg and show no symptoms of low blood pressure, while others who have normally have blood pressure levels at 130/80 mm Hg may show symptoms of low blood pressure when blood pressure falls down to 100/60 mm Hg.

So it is clear that the low blood pressure varies from person to person. When the blood pressure is low, there is not sufficient flow of the blood to deliver enough oxygen and nutrients to vital organs such as brain, heart, and kidney and as a result of that the organs do not function normally and may be damaged permanently.

Sometimes it is possible that one is with low blood pressure and show no sign and symptoms at all. But here are some of the general signs and symptoms of low blood pressure.

1) Dizziness
2) Palpitations
3) Confusion
4) Nausea
5) Tiredness
6) General weakness
7) Light-headedness and fainting
8) Blurred vision
9) Temporary loss of consciousness.

There are some more factors that can cause low blood pressure in you:

1) Advanced diabetes
2) Alcohol
3) Medications used for surgery
4) Anti-anxiety agents
5) Dehydration
6) Changes in heart rhythm
7) Treatment for high blood pressure
8) Diuretics
9) Heart medicines
10) Anaphylaxis
11) Some antidepressants

To measure your blood pressure on own, you can use Automatic Blood Pressure Monitors recording machine.

The pressure of the blood against the walls of the arteries is known as blood pressure. Low blood pressure occurs when the blood pressure level is much lower than the normal levels of blood pressure. The normal levels of blood pressure vary from person to person. Generally, normal blood pressure falls in the range of 90/60 mm Hg to 130/80 mm Hg.

Mainly there are two types of low blood pressure conditions:

1) Orthostatic Hypotension,
2) Neurally Mediated Hypotension,

a) Dizziness,
b) Lightheadedness
c) Headache
d) Blurred or dimmed vision
e) Syncope

There are some anti-depressant drugs that can also cause orthostatic hypotension. Diabetes, Addison's disease, atherosclerosis, and certain neurological disorders are also believed to be the cause of this condition.

Blood Pressure Products:

Some sort of medication can also be used to treat the condition such as fludrocortisone (Florinef), erythropoietin and midodrine.

Apart from the medication, with some changes in lifestyle the condition can also be healed. Here is the list of desired lifestyle changes:

a) Check blood pressure regularly.
b) Stand slowly rather than quickly.
c) Maintain an elevated salt intake.
d) Maintain a proper fluid intake to prevent the effects of dehydration.
e) Eat multiple smaller meals rather than fewer larger meals.
f) Take extra care when standing after eating.

neurally mediated hypotension. Neurally mediated hypotension is also known as the fainting reflex and neurocardiogenic syncope.

a) Recurrent lightheadedness
b) Fainting
c) Prolonged fatigue after a modest amount of physical activity
d) Chronic fatigue
e) Muscle aches (or fibromyalgia)
f) Headaches
g) Mental confusion
h) Mental fog.

a) Fludrocortisone (Florinef),
b) Beta-blockers (Atenolol),
c) Disopyramide (Norpace),
d) Fuoxetine (Prozac),
e) Sertraline (Zoloft),
f) Ephedrine
g) Pseudoephedrine,
h) Theophylline, methylphenidate (Ritalin), and
i) Midodrine.

Your doctor will determine the best possible combination for your personal situation. But again I will say, the adequate intake of fluid is very necessary.

Generally, normal blood pressure of a person falls in the range of 90/60 mmHg to 120/80 mmHg. Low blood pressure is a condition in which the blood pressure of a person is lower than the normal BP levels. When the blood pressure is low, there is insufficient flow of blood in the body.

Low blood flow means low deliverance of oxygen and nutrients to vital organs such as the brain, heart, and kidney. In such a case, the first organ to malfunction is the brain. And when the blood pressure falls too low, all the organs of the body start malfunctioning and may get damaged permanently.

It is possible that some individuals may have a blood pressure of 90/50 mmHg and still not show any symptoms of low blood pressure. On the other hand, it is also possible that a person, who has a normal blood pressure of 130/80 mmHg will show symptoms of low blood pressure if his blood pressure falls down to 100/60 mmHg, which in itself is not exactly low blood pressure problem.

In the first case, the person did not show any symptoms of low blood pressure as the blood pressure recorded was his normal and constant blood pressure level. But in the second case, the person showed symptoms of low blood pressure because his body was used to a blood pressure level of 130/80 mmHg. And when his blood pressure fell down to 100/60 mmHg, it was considered as low blood pressure by his body.

Some other causes of low blood pressure include:

1) Advanced diabetes
2) Alcohol
3) Medication used for surgery
4) Anti-anxiety agents
5) Dehydration
6) Changes in heart rhythm
7) Treatment for high blood pressure
8) Diuretics
9) Medication used for heart disorders
10) Anaphylaxis
11) Some antidepressants

Treatment for low blood pressure: Low blood pressure in itself is not treated. What is treated is the underlying reason that causes low blood pressure.
