White coat syndrome (also called white coat hypertension) is when a person’s blood pressure reads high in a clinical setting (hospital, clinic, GP surgery etc) but is normal at home or in everyday life.
Why it happens
Anxiety or stress when seeing healthcare professionals
Fear of diagnosis or bad news
Past negative medical experiences
The body’s stress response → adrenaline raises BP temporarily
Key features
High BP in clinic 📈
Normal BP outside clinic 📉
No symptoms most of the time
More common in older adults, pregnant women, and people with anxiety
Why it matters
It can lead to misdiagnosis of hypertension
Some people with white coat syndrome have a higher future risk of developing true hypertension
Important not to over-treat with medication unnecessarily
How it’s diagnosed
Home blood pressure monitoring (HBPM)
24-hour ambulatory blood pressure monitoring (ABPM) – gold standard
Multiple readings over time, not a single clinic reading
How to reduce it (practical tips)
Sit quietly for 5 minutes before BP is taken
Avoid caffeine, smoking, or exercise 30 minutes before
Take slow deep breaths during measurement
Ask for BP to be taken at the end of the appointment
Use a validated home BP monitor and keep a log
Treatment
Usually no medication if home/ambulatory readings are normal
Focus on lifestyle: low salt, exercise, weight management, stress reduction
Regular follow up
