Can generalised anxiety disorder cause white coat hypertension?

White coat hypertension describes blood pressure that is higher in a healthcare setting than during usual daily life. Worry about the appointment, unfamiliar surroundings, conversation, or the cuff itself can activate the body's stress response and temporarily raise the reading. Generalised anxiety disorder may make this response more likely, but a single high reading cannot show whether the pattern is limited to the clinic. Some people with high clinic readings also have raised pressure outside appointments, so the distinction needs careful checking.

Arrive with time to settle, sit with your back supported and feet on the floor, and avoid talking during the measurement. Use a correctly sized cuff on a bare arm supported at heart level. Your clinician may repeat the reading after rest or recommend home monitoring, with readings taken at agreed times and recorded with notes about symptoms or stress. Do not change blood-pressure medicine based on one reading. Share your home record so treatment decisions reflect your usual pattern as well as clinic measurements.

Arrange a review for repeated high readings, headaches that keep returning, or concerns about anxiety affecting appointments. Seek urgent help for a very high reading accompanied by chest pain, severe breathlessness, weakness on one side, confusion, fainting, or sudden vision changes. Anxiety should not be assumed to explain symptoms that could indicate an acute medical problem.

Ask whether home monitoring or ambulatory monitoring would clarify your readings, how to prepare for measurement, whether anxiety treatment could help, and which blood-pressure symptoms require emergency care.
