Labile hypertension causes your blood pressure to fluctuate from high to normal frequently. If blood pressure fluctuations aren't within normal range and occur regularly, you may have labile hypertension. If it's connected to a certain activity or situation and resolution of the problem normalizes the blood pressure, you may not need medical assistance. So you may not even notice a spike when it occurs.Īlthough sudden increases in blood pressure might seem concerning, this may not always be the case. It's worth noting that many people don't experience any symptoms of high blood pressure. When you measure it again in half an hour, the blood pressure goes down to 120/80. You measure the blood pressure and see 140/90mm Hg. For example, you suddenly start experiencing symptoms of high blood pressure that can include: Temporarily high blood pressure is a blood pressure spike. Hypertensive crisis – over 180mm Hg systolic and/or over 120mm Hg diastolic (if these levels hold, the person requires immediate medical attention).Ī hypertensive crisis warrants immediate medical attention. Hypertension (stage II) – at least 140mm Hg systolic or at least 90mm Hg diastolic Hypertension (stage I) – 130–139mm Hg systolic or 80–89mm Hg diastolic However, it could signal a problem when blood pressure remains high for many hours.Īccording to American Heart Association, there are five blood pressure ranges:²Įlevated – 120–129mm Hg systolic and less than 80mm Hg diastolic Second (lower) number – diastolic pressure – pressure in the arteries when the heart is resting between beats.īlood pressure can rise and fall throughout the day. The blood pressure is recorded by two numbers:įirst (higher) number – systolic pressure – pressure in the arteries when the heart contracts. Blood pressure is the force exerted by your blood within your arteries, and the contraction of the heart muscle creates it.
