It’s normal to occasionally feel dizzy when you stand up, but if it occurs frequently or lasts longer than a few seconds, see your doctor. They will do a physical exam and take a medical history, check your blood pressure, and possibly do some lab tests or an ECG to try to figure out a cause. See your doctor right away if you become so dizzy upon standing that you pass out. Often, your regular doctor can figure out what is causing your orthostatic hypotension with a blood test. They can check your blood sample to see if there’s a problem with your thyroid, adrenal gland, or nervous system, and to see if you’re anemic. If you notice that you have symptoms of hypotension – dizziness, lightheadedness, nausea, confusion, blurry vision, weakness, or passing out – start to keep a journal. Record what symptoms you experience and how long they last. Note what you were doing right beforehand and earlier that day, such as exercising or being in the sun. Take this record with you to your doctor’s office. Some people get low pressure after they eat. Take note if your symptoms occur after a meal. It’s normal to experience low blood pressure when you’re pregnant because of the changes your body goes through to accommodate for the baby. Usually, your blood pressure will return to normal after you give birth. Talk to your doctor about it if your symptoms last longer than a few seconds or make you so dizzy you feel like you might faint or fall. Sometimes, postural hypotension can be a sign that something is wrong with how your heart is working. Valve problems, slow heart rate, heart failure, and a history of heart attack can all limit how well your heart works and cause low blood pressure when you stand up. Ask your doctor for a referral to a heart specialist, or cardiologist. Cardiologists can do special tests to check your heart valves and see how well your heart pumps blood.
