Blood pressure is a measurement of the force of the blood against the walls of the blood vessels during and after each beat of the heart. Low blood pressure (hypotension) means that your blood pressure is much lower than normal. Some people, especially young, slim women, may have slightly low blood pressure without symptoms. However, in many people, low blood pressure can cause symptoms such as dizziness or light-headedness. When your blood pressure is too low, your heart, brain, and other organs do not get enough blood.
Low blood pressure can be caused by many things, including heart problems and some medicines. Uncontrolled diabetes can cause your blood pressure to drop, and so can a severe allergic reaction or infection. Another cause is dehydration, which is when your body loses too much fluid.
Treatment for low blood pressure depends on the cause.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
