You have high blood pressure if readings average140/90 or higher -- for either number -- though you may still have no symptoms. At 180/110 and higher, you may be having a hypertensive crisis. Rest for a few minutes and take your blood pressure again. If it is still very high, call 911. A hypertensive crisis can lead to a stroke, heart attack, kidney damage, or loss of consciousness. Symptoms of a hypertensive crisis can include a severe headache, anxiety, nosebleeds, and feeling short of breath.
Hypotension (HI-po-TEN-shun) is abnormally low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is measured as systolic (sis-TOL-ik) and diastolic (di-a-STOL-ik) pressures. Systolic refers to blood pressure when the heart beats while pumping blood. Diastolic refers to blood pressure when the heart is at rest between beats. You most often will see blood pressure numbers written with the systolic number above or before the diastolic number, such as 120/80 mmHg.
