Low blood pressure is a condition in which the blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through arteries and veins. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney; the organs do not function normally and may be permanently damaged. Unlike high blood pressure, which is defined on the basis of blood pressure alone, low blood pressure is defined primarily by signs and symptoms of low blood flow. In fact, some individuals may have a blood pressure of 90/50 and have no signs or symptoms of low blood pressure, and, therefore, not have low blood pressure while others who normally have a blood pressure of 130/80 may develop Low Blood Pressure Symptoms and signs of low blood pressure if their blood pressure drops to 100/60.
Some people with low blood pressure are in good physical condition with strong cardiovascular systems and a reduced risk of heart attack and stroke. But low blood pressure can also signal an underlying problem, especially when it drops suddenly or is accompanied by signs and symptoms such as:
o Dizziness or lightheadedness
PRESSURE
o Fainting (syncope)
o Lack of concentration
o Blurred vision
o Nausea
o Cold, clammy, pale skin
o Rapid, shallow breathing
o Fatigue
o Depression
o Thirst
There are two main mechanisms, or causes, of low blood pressure. The most common mechanism is reduced blood volume, which can have many different causes. Hemorrhage, or massive blood loss; not drinking enough fluids such as water or juice; or persistent diarrhea or vomiting can all cause reduced blood volume. Another cause of hypovolemia is excessive diuretics use. This causes the body to produce excessive amounts of urine, which can reduce the amount of fluid in the body very quickly. Another mechanism that causes low blood pressure is decreased cardiac output. This is usually caused by heart failure of some type. This cause of hypotension can quickly lead to cardiogenic shock, or shock caused by a lack of blood circulation.
Low blood pressure can accompany anemia especially when you change positions from sitting to standing. Anemia is from a low blood count that can be brought on by excessive bleeding or iron deficiency. There are some natural treatments you could also try if your blood pressure is mildly low and if you have moderate symptoms.
