Hypotension, or low blood pressure, occurs when systolic pressure is below 90, and diastolic pressure is below 60. Low blood pressure indicates inadequate blood flow to the vital organs, including the heart and brain. For healthy people, low blood pressure is typically not an issue. Causes of low blood pressure include loss of blood, low body temperature, sepsis, heart disease, medication, dehydration, or an allergic reaction. The following are signs of low blood pressure.
Do you feel dizzy or lightheaded when you stand up too quickly? A sudden drop in blood pressure causes this feeling. Low blood pressure indicates insufficient oxygen flow to the vital organs. When the brain is cut off from its oxygen supply, it cannot function properly. This feeling is known as orthostatic hypotension or postural hypotension. If the lightheadedness persists, see a doctor.
