Blood pressure is the force of your blood pushing against your artery walls. It’s measured in millimetres of mercury (mmHg) and written as two numbers — for example, 120/80 mmHg.
Systolic pressure (top number): the pressure when your heart beats.
Diastolic pressure (bottom number): the pressure when your heart rests between beats.
Blood Pressure Ranges (Adults)
| Category | Systolic (mmHg) | Diastolic (mmHg) | What It Means |
|---|---|---|---|
| Low (Hypotension) | Below 90 | Below 60 | Blood pressure is lower than normal. Some people feel fine, but if you're dizzy, lightheaded, or fainting, contact your provider. |
| Normal | 90–119 | 60–79 | Healthy blood pressure. |
| Elevated | 120–129 | Below 80 | Early sign of risk. |
| High (Hypertension Stage 1) | 130–139 | 80–89 | May need monitoring and possibly treatment. |
| High (Hypertension Stage 2) | 140 or higher | 90 or higher | Often requires medication and close follow-up. |
| Hypertensive Crisis | Over 180 | Over 120 | Seek medical help right away. |
Blood Pressure and Gender-Affirming Care
Some factors related to gender-affirming care can influence blood pressure:
Hormone therapy: Oestrogen or testosterone may cause slight changes in blood pressure.
Binding, tucking, or packing: These practices can sometimes increase physical stress on your body so it can be helpful to take breaks.
Mental health and stress: Stress can affect blood pressure. Accessing supportive, affirming care and mental health resources can make a real difference.
Lifestyle Suggestions for Healthy Blood Pressure
Try to eat a balanced diet.
Try to stay active.
Maintain a healthy weight.
Limit alcohol and avoid smoking.
Manage stress and get enough sleep.
Take your medications (including hormones) exactly as prescribed.
