Blood pressure can tell your doctor a lot about your health. A number that’s a little low or a little high may be a sign of potential issues. Changes in your blood pressure between visits can be an indication of health issues, too.
Your blood pressure is a reading of the force with which blood is passing through your circulatory system. Blood pressure changes naturally many times a day. Most changes are normal and predictable. When these spikes and valleys in your blood pressure occur, you may not experience unusual signs or symptoms. These fluctuations may be brief and fleeting.
Fluctuating blood pressure can be caused by several issues.
Stress
Emotional stress and anxiety can temporarily increase blood pressure. Over time, excess stress can take a toll on your cardiovascular system and might lead to permanent blood pressure problems. Find out more about the effects of stress on your body.
White-coat syndrome
White-coat syndrome occurs when worry or stress from a doctor’s appointment causes a temporary spike in blood pressure. At home, you may find your reading is normal. This high blood pressure reading doesn’t mean you have hypertension (high blood pressure). However, people with white-coat hypertension are more likely to develop high blood pressure.
Medication
Both over-the-counter and prescription medications can impact your blood pressure. Some medications, like diuretics and blood pressure pills, are designed to lower your blood pressure numbers. Others, like cold and allergy medications, can increase your blood pressure.
Activity
Exercise, talking, laughter, and even sex can cause blood pressure fluctuations.
Food and drink
What you eat or drink might impact your blood pressure reading. Foods high in tyramine, a substance found in aged foods, can increase blood pressure. This includes foods that are:
- fermented
- pickled
- brined
- cured
Drinks with caffeine can boost blood pressure numbers temporarily, too.
Adrenal issues
Your adrenal system is responsible for hormone production. Adrenal fatigue occurs when your hormone production is low. Your blood pressure may fall as a result. An overactive adrenal system can cause sudden spikes in blood pressure and hypertension.
Pheochromocytoma
This rare tumor develops in the adrenal glands and impacts hormone production. It can cause sudden bursts of irregular blood pressure readings with normal spans in between
