In physiology and medicine, hypotension is abnormally low blood pressure condition.
This is not a disease, but rather a physiologic state. The opposite is hypertension, or high blood pressure. Blood pressure is the force of blood gushing through the walls of the arteries as the heart pumps out blood. When the pressure is below 90/60mmHg, which is considered low, this condition is known as low blood pressure or hypotension.
Blood pressure is continuously regulated by the autonomic nervous system, using an elaborate networks of receptors, nerves and hormones to balance the effects of the Sympathetic nervous sysytem, which tends to raise blood pressure, and the parasympathetic nervous system, which lowers the blood pressure, The vast and rapid compensation abilities of the autonomic nervous system allow normal individuals to maintain an acceptable blood pressure over a wide range of activities and emotions.
Symptoms of hypotension:
The symptoms of hypotension is light headedness or dizziness.If the pressure is too low, fainting and seizures will occur.Among others,low blood pressure or hypotension is associated with the following sympotoms, which are not effects of hypotension, rather related to causes of low blood pressure.
a]Chest pain
b]shortness of breath
c]high fever
d]stiff neck
e]foul-smelling urine.
Causes:
Low blood pressure causes can be due to, among others,
1]Hormonal changes
2]widening of the blood vesseles
3]Medicine side effects
4]Heart and endocrine problems
Types:
1]Orthostatic hypotension, also kown as 'postural hypotension', is common.It occurs when the body
changes its position after a while, like standing up from a seated or lying position.Even antidepressants can have this side effect.If there is a drop of 20/10mmHg in blood pressure,this will indicate hypotension.
2]Another, but very rare type is called postprandial hypotension, which occurs 30-60 minutes after eating a substancial meals.Here a huge quantity of blood is diverted to the intestines, thus negating blood to other vital parts,such as brain.
Treatment:
The treatment for ypotension depends on its cause. Adding electrolytes to a diet can relieve symptoms of mild hypotension.For rare and severe cases hospitalisation is recommended.

The biggest cause behind that is hormonal changes,and It is often associated with shock, though not necessarily indicative of it.
