A low blood pressure is typically defined as readings below 90/60mm Hg. The upper reading is termed the systolic blood pressure, and the lower reading is termed the diastolic blood pressure. Think of the systolic blood pressure as the amount of pressure that heart generates with each contraction, to cause forward flow of blood through the major vessels in the body. The diastolic blood pressure, on the other hand, can be considered the ongoing pressure causing continued circulation when the heart has stopped contracting, and is generally thought to represent the stiffness of arteries, supplied by the heart.
We often look at high blood pressure much more frequently, with general advice to the public to immediately tackle it and seek medical advice. It is a very important condition which has long-term cardiovascular effects and is important to identify the conditions main causes and symptoms.
However, low blood pressures can be highly symptomatic causing symptoms which are generally related to inadequate blood flow to the brain, manifesting as dizziness, light-headedness, fainting, and other more unusual symptoms such as palpitations, chest pain, nausea and brain fog.
