Causes of low blood pressureYour blood pressure can vary depending on the time of day. It gradually increases throughout the day. What you're doing and how you're feeling can also affect it. There are many possible causes of low blood pressure. It may be low because you're fit and healthy, or you may have inherited it from your parents. Low blood pressure is not always a sign of a problem. But if you have symptoms of low blood pressure, your doctor can diagnose the condition and uncover the cause. Symptoms of dizziness and lightheadedness when you stand up from sitting or lying down -- with a decrease in your blood pressure -- may indicate a condition called postural hypotension. A wide range of underlying conditions may also cause your symptoms. It's important to identify the cause of low blood pressure so appropriate treatment can be given. The doctor will look at your medical history, age, specific symptoms, and the conditions under which the symptoms occurred. They will do a physical exam and may repeatedly check your blood pressure and pulse rate -- after you've been lying down for a few minutes, right after you stand up, and within a few minutes after you stand quietly. Other tests may be performed, such as an ECG (electrocardiogram) to measure heart rate and rhythm and an echocardiogram (an ultrasound test to visualize the heart). You may also have blood tests to look for anemia or problems with your blood sugar levels. More sophisticated home ECG monitoring (a Holter monitor or "event" monitor) may be necessary to check for heart problems that come and go or an irregular heart beat that can cause your blood pressure to drop suddenly. An exercise stress test or, less commonly, an electrophysiology test (EP test) may also be helpful. Some forms of postural hypotension may require a test called a "tilt table" test. This test evaluates the body's reaction to changes in position. The person lies on a table, is safely strapped in, and the table is raised to an upright position for up to an hour. Blood pressure, heart rate, and symptoms are recorded. Often, medications are given to help guide treatment.

What happens if your blood pressure drops too low?A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg — a drop from 110 mm Hg systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting. And big drops, such as those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening.
What causes sudden drop in low BP?Sudden drops in blood pressure most commonly occur in someone who's rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time.
