At times patients of postural hypotension, a type of low blood pressure, all of a sudden might feel dizzy and drowsy which may cause an accident.



Normally when a person springs up from a sitting or lying position, his blood vessels have to contract in order to maintain normal blood pressure in the new posture and this process is carried out automatically by reflex action of the nervous system. However, if a person has postural hypotension, the reflex action in some way gets defective. With the result, the blood pressure falls and the flow of blood to the brain is temporarily reduced by a sudden change of posture. The result is dizziness or even brief loss of consciousness.

Nutritional hypotension, the other type of low blood pressure, is due to unbalanced nutrition.



This faulty nutrition allows the tissues forming the walls of the blood vessels to become over-relaxed to the point of being flabby or overstretched which reduces their capacity to absorb adequate amount of oxygen and nutrients from blood. As a result, the person with low blood pressure from fatigue, usually lacks endurance, becomes oversensitive to cold and heat, requires more sleep than healthy individuals and develops a rapid pulse on exertion. Such persons invariably feel more tired when they get up in the morning than they felt when they had retired to bed the previous day.

Hypotension is not as alarming a condition as it is disturbing and causing irritating discomfort.
