Blood pressure is the pressure or force of blood exerted upon the walls of the arteries as the heart pumps out blood. Blood pressure is measured as systolic and diastolic. Normal value of blood pressure in adults is 120/80 mm.Hg. (120-systolic, and 80- diastolic). When the circulation of blood is too low to supply sufficient oxygen and nutrients to organs or tissues of the body, it is referred as low blood pressure. Although low blood pressure is not a common cause of concern but if blood pressure is markedly low, it can produce many abnormal symptoms, low blood pressure can be a result of any disorders. Such as hemorrhage, endocrine disorders, dehydration, cardiovascular diseases. There is no specific threshold for defining low blood pressure, it is considered too low when it produces abnormal symptoms. Usually when it reaches below 90/60 mmHg considered as low blood pressure.
Causes of low blood pressure
Hemorrhage – excessive bleeding due to any injury or accident reduces amount of blood in the body, causes severe reduction in the blood flow and ultimately leads to low blood pressure

Hypotension due to infections – when infection reaches to flowing blood it produces septicemia which can cause severe and life threatening fall in blood pressure.
Anemia – in which there is lack of production of red blood cells, and lack of oxygen to the tissues of organs which ultimately leads to low blood pressure.
