Frequently Asked Questions
Blood pressure is the force of blood pushing against the walls of your arteries. It is measured in two numbers: systolic (when your heart beats) over diastolic (when your heart rests between beats), expressed in mmHg.
High blood pressure (hypertension) can be caused by a poor diet (high sodium), lack of exercise, obesity, smoking, excessive alcohol, stress, age, genetics, and certain medical conditions. Lifestyle changes and medication can help manage it.
If your reading consistently falls in Stage 1 or Stage 2 hypertension, consult your doctor. A hypertensive crisis (above 180/120) requires immediate medical attention, especially if accompanied by chest pain, shortness of breath, or severe headache.
