Blood pressure is the amount of pressure exerted by the blood on the walls of the blood vessels when flowing through them. As per the World Health Organization (WHO), the normal blood pressure is 120/80 mm Hg, and it rises and falls several times in a single day.
Fluctuations in blood pressure can be seen due to physical activity, emotional events, body posture, high salt diet, excessive alcohol consumption and sleep deprivation. However, if the blood pressure fluctuates regularly and far more than usual, it may be an indication of labile hypertension. Due to the lack of enough studies on this topic, there is no clear definition or standard criteria to determine the range of abnormal fluctuations.
What are the signs of labile hypertension?
There are no definite signs of labile hypertension as people may or may not show symptoms. The symptoms associated with labile hypertension include:
Who is at increased risk of labile hypertension?
Anyone can experience labile hypertension as the blood pressure spikes in response to stressful events, such as an accident, physical exertion or minutes before an interview. However, some people are at increased risk of experiencing labile hypertension, these include:
What causes labile hypertension?
The causes of labile hypertension include:
Is labile hypertension a sign of an underlying disease?
Some medical conditions may trigger labile hypertension, such as:
What is the difference between labile hypertension and paroxysmal hypertension?
Paroxysmal hypertension is one other type of hypertension marked with fluctuation in the blood pressure between normal and high levels. While it may seem similar to labile hypertension, both of these are different from each other. The differences include:
How is labile hypertension diagnosed?
To diagnose labile hypertension, the blood pressure of the affected person is monitored using an ambulatory blood pressure monitor. This device is worn by the person on their arm for 24 hours, the machine measures the blood pressure every 15 to 30 minutes during the day and every 30 to 60 minutes at night. The readings of the entire day would allow the doctor to identify the reason for the blood pressure spikes.
What can be done to manage labile hypertension?
Since there are no specific criteria for managing labile hypertension, the management of the condition would be done based on the underlying cause:
High-risk groups must reduce their consumption of processed foods and take up moderate-intensity exercise (brisk walking, cycling or swimming) for at least 30 minutes every day to reduce their risk of developing labile hypertension.
High blood pressure or hypertension is a major contributor to various cardiovascular diseases including heart failure and stroke. A 20-year biennial follow-up study of Framingham including more than 5000 participants concluded that labile hypertension is an exaggerated response of the body to a stressful situation and is considered a less threatening event occurring before fixed hypertension.
To evaluate the risk of the potential damage that can be caused by high blood pressure, it is necessary to assess the amount of spike, the number of cardiovascular risks (diabetes, smoking, high cholesterol and others) present in the person and if any specific organ is getting damaged due to the spike. It is important to get an accurate diagnosis and proper treatment early enough to prevent any major damage.
For any questions relating to heart health including labile hypertension, you can consult a cardiologist.

Recent studies say that climbing 60 steps in one minute is a sign of good heart health. It was found that the longer time taken to ascend stairs corresponds with a higher risk of cardiac problems later.
People with diagnosed heart conditions as well as healthy individuals to get themselves tested for hidden heart diseases that may not often have clear warning signs.
According to a new study, higher levels of stress can increase one’s risk of high blood pressure and cardiovascular events such as heart attack or stroke.
