What is white coat syndrome? We explore the definition, symptoms, and causes. Plus, learn how to prevent, treat, and manage white coat syndrome with our 7 tips.
Going to the doctor can be stressful, of course, but does your blood pressure spike before you even see your physician? Perhaps as soon as you pull into the parking lot, take a seat in the waiting room, or even when the nurse puts the blood pressure cuff on your arm, you can feel your heart begin to race.
If this sounds familiar, you may struggle with white coat syndrome, also known as white coat hypertension. People with white coat syndrome experience unusually high blood pressure readings when they’re having a medical exam. These readings aren’t typical and are caused by the anxiety and stress associated with doctor visits.
What is white coat syndrome?
White coat syndrome’s name comes from the traditional white lab coats that doctors sometimes wear, but, of course, this anxiety can be triggered whether your doctor, nurse, dentist, or any medical professional, is wearing scrubs, a uniform, or even ordinary clothes.
It’s important to note that white coat syndrome is different from chronic hypertension, where you have consistently high blood pressure that doesn’t fluctuate based on your environment. Those with white coat syndrome experience a temporary increase in blood pressure that’s different from usual levels, which are often normal at home.
Because high blood pressure readings seen in a clinical environment might suggest a condition that isn't present in a more relaxed, everyday setting, white coat syndrome can lead to misdiagnosis of hypertension.
What causes white coat syndrome?
White coat syndrome primarily occurs due to anxiety. Many people feel nervous or stressed during medical appointments, and this can stimulate the body’s stress pathways. Anxiety can cause a surge in heart rate and blood pressure, which then shows as a higher than normal reading when the doctor takes your blood pressure.
Some people may be more susceptible to white coat syndrome than others, and there may be several factors involved:
Anxiety: A general predisposition to anxiety, especially in new or uncomfortable situations
Trauma: Negative past experiences in medical settings, which may contribute to expecting stressful outcomes
Fear of needles or medical exams: General nervousness about being examined by a medical professional
Fear of a negative diagnosis: Fear of medical results or a doctor finding something wrong with you can lead to white coat syndrome.
Lack of experience: Lack of familiarity with medical procedures, which can enhance feelings of vulnerability or fear

What are the symptoms of white coat syndrome?
When some people enter a clinical setting, anxiety can trigger a stress response in their body, which is a natural reaction designed to prepare us to handle what our bodies perceive as a threat or a challenging situation.
During this stress response, several physiological changes occur. The body releases stress hormones like adrenaline, which, in turn, increase the heart rate and constrict blood vessels. This process is meant to boost blood flow and oxygen to key areas of the body, preparing us to face potential challenges. Of course, this doesn’t happen at the doctor’s office, so instead, this heightened state can lead to an increase in blood pressure, as our bodies aren’t able to tell the difference between a harmful environment where we need protecting and a perceived dangerous environment.
How to prevent, treat & manage white coat syndrome: 7 tips
Preventing, treating, and managing white coat syndrome involves a combination of practical steps aimed at reducing anxiety, improving your comfort, and ensuring accurate blood pressure monitoring.
Preventing white coat syndrome
Practice relaxation techniques: Before and during your doctor's appointments, try to relax by using deep breathing exercises, meditation, or listening to calming music. These techniques can help lower your heart rate and reduce stress.
Establish a good relationship with your healthcare provider: Make an appointment with a doctor or nurse you know and feel comfortable with. If your appointment is with someone you haven’t met before, tell them about any fears or concerns you have, so they can help put you at ease.
Bring a friend or family member: Have someone you trust with you to provide emotional support during medical visits.

Treating and managing white coat syndrome
Monitor your blood pressure at home: Regularly take readings in a more familiar environment to give a more accurate reflection of your blood pressure over time. This can help you and your healthcare provider understand how much your blood pressure might change in response to a clinical environment.
Lifestyle changes: Adopt a healthy lifestyle to help improve your overall cardiovascular health. This might include a balanced diet, regular physical activity, and managing stress through hobbies or social activities.
Consider psychological interventions: If your anxiety is significant, try therapies like cognitive behavioral therapy (CBT) to help manage the thoughts and feelings that contribute to your stress and anxiety.
Consult your doctor about medication: If lifestyle adjustments and coping strategies don’t sufficiently control your anxiety, or if your blood pressure is elevated even outside of clinical settings, talk to your doctor for treatment options.
💙 Create Rest and Relaxation by tensing and releasing your muscles, which can help create a sense of safety and ease.
White coat syndrome FAQs
Is white coat syndrome dangerous?
While white coat syndrome itself is not directly harmful, it can lead to complications if it’s not appropriately addressed. The primary concern is that it may mask or be mistaken for chronic hypertension. High blood pressure readings in a clinical setting could lead to unnecessary treatment with medications if misdiagnosed. But they might also prevent the detection of actual hypertension if the high readings are dismissed as merely stress-related. Monitoring your blood pressure while you’re in different settings can help ensure accurate diagnosis and treatment.
Can white coat syndrome lead to permanent hypertension?
White coat syndrome doesn’t necessarily lead to permanent hypertension. However, people who consistently experience high blood pressure in medical settings may be at an increased risk of developing sustained hypertension over time. This could be due to underlying anxiety or stress mechanisms that—if frequently activated—may contribute to long-term changes in cardiovascular function. Regular monitoring and management of stress and blood pressure can help prevent the progression to chronic hypertension.
How often should someone with white coat syndrome monitor their blood pressure at home?
For people diagnosed with white coat syndrome, daily monitoring at home can help establish a baseline and understand the typical patterns of their blood pressure. Once a stable pattern is observed, the frequency of monitoring can be reduced. The data collected can help healthcare providers make more informed decisions about whether there’s a need for further evaluation or treatment.
What role does anxiety play in white coat syndrome?
Anxiety is often the primary trigger for the temporary spikes in blood pressure seen in clinical settings. The anticipation of medical procedures or receiving health news can activate the body's stress response, leading to elevated blood pressure readings. Managing anxiety through relaxation techniques, psychological therapies, or simply having a supportive conversation with a healthcare provider can help mitigate these effects.
Are there specific populations more prone to white coat syndrome?
White coat syndrome can affect anyone, but certain populations may be more susceptible:
People with a history of anxiety disorders
Those who’ve had negative experiences in medical settings
Patients who generally feel anxious about their health
Elderly patients
People who don’t visit the doctor often
