What to tell us about your symptoms

High blood pressure often has no obvious symptoms. A single reading is not the whole picture, and feeling well does not by itself tell you whether blood pressure is controlled.

What the video visit can help with

Share the actual readings, when you took them and which medicines you use. Explain whether the concern is a new measurement, a change from your usual pattern or a question about an established treatment plan.

When an examination or testing may be needed

Accurate measurements and sometimes laboratory tests or an examination are part of blood pressure care. A video call cannot produce a reliable blood pressure measurement without appropriate equipment.

Discussing treatment

Our physicians and nurse practitioners can discuss your plan and whether further assessment or prescription review is appropriate. Do not change or double a medicine on your own because of one reading.

When to get care in person

Chest pain, severe shortness of breath, weakness, trouble speaking or other stroke-like symptoms need emergency help. A severely elevated reading also requires prompt professional guidance, even when you feel well.

Before your visit

Have your medication list and a few recent readings ready, including the time and circumstances. Mention missed doses plainly; the information helps the clinical discussion.

Questions about this care

Can you measure my blood pressure through the camera?

No. Bring readings from appropriate equipment. The visit can help interpret the history and choose the next step, but it is not a substitute for obtaining a measurement.

Your next step

Let’s talk about getting you care.

Start with a video visit. Your clinician can help you understand what can be addressed online and what needs care in person.
