Red flags & when to go in person for High Blood Pressure (Reading)

Audience: adult

High blood pressure (hypertension) is a common condition that often has no symptoms but can increase the risk of serious health problems like heart attack and stroke. Telemedicine can help you monitor your blood pressure readings, discuss lifestyle changes, and adjust medications safely in many cases. However, certain warning signs or very high readings require prompt in-person evaluation to prevent complications. Knowing when to seek urgent care is important for your safety. This guide explains red flags to watch for, what telemedicine can and cannot do for high blood pressure, and how to prepare for and follow up after a telemedicine visit.

Red flags — go in person / ER

• Blood pressure reading above 180/120 mm Hg — go to emergency care immediately.
• Sudden chest pain, severe headache, or difficulty breathing — seek urgent in-person evaluation.
• New weakness, numbness, confusion, vision changes, or difficulty speaking — get emergency medical attention.

What telemedicine can do

• Reviewing and discussing home blood pressure readings.
• Medication management and adjustments for stable hypertension.
• Providing lifestyle advice and education on blood pressure control.
• Monitoring symptoms and side effects related to hypertension treatment.

What telemedicine cannot do

• Evaluating hypertensive emergencies or crises.
• Performing physical exams or urgent diagnostic tests.
• Managing severe symptoms such as chest pain or neurological deficits.
• Administering emergency treatments or procedures.

Understanding High Blood Pressure Readings

Blood pressure measures the force of blood against your artery walls. It is recorded as two numbers: systolic (pressure when your heart beats) over diastolic (pressure when your heart rests). Normal readings are typically below 120/80 mm Hg. Elevated or high readings may require lifestyle changes or medication to reduce health risks.

When to Use Telemedicine for High Blood Pressure

Telemedicine visits can help you review your home blood pressure readings, discuss symptoms, adjust medications, and get advice on diet and exercise. If your readings are mildly elevated or well-controlled, a virtual visit may be sufficient for routine care and monitoring.

FAQs

Can I rely on home blood pressure monitors for accurate readings?

Home blood pressure monitors can be accurate if they are validated and used correctly. Follow the manufacturer's instructions carefully, measure at the same time daily, and sit quietly for 5 minutes before measuring. Bring your monitor to your healthcare provider occasionally to check its accuracy.

What should I do if my blood pressure is high but I feel fine?

High blood pressure often has no symptoms but can still cause damage. If your readings are elevated, discuss them with your healthcare provider. They may recommend lifestyle changes or medication to lower your risk. However, if your readings are extremely high (above 180/120 mm Hg), seek urgent care even if you feel well.

How often should I have my blood pressure checked?

The frequency depends on your individual health and blood pressure control. Many people with hypertension have check-ins every 3 to 6 months, but your provider may recommend more frequent monitoring, especially if you are adjusting medications or have other health conditions.

Can telemedicine replace all in-person visits for high blood pressure?

Telemedicine is helpful for many routine visits but cannot replace all in-person care. Physical exams, blood tests, or urgent evaluations require in-person visits. Always follow your provider's advice about when to come in person.
