A clear guide to what hypertension is, its risk factors, how to check your blood pressure, lifestyle steps to lower it, and when to seek medical help.
What is Hypertension?
Hypertension, commonly called high blood pressure, is a condition where the force of blood against the artery walls is consistently too high. Over time, this can damage blood vessels and increase the risk of heart disease, stroke, and kidney problems.
Causes and Risk Factors
Most cases develop gradually and are linked to lifestyle and genetic factors.
- Age – risk rises after 45 years
- Family history of hypertension
- Excess salt intake
- Physical inactivity
- Obesity
- Stress and excessive alcohol consumption
Symptoms
High blood pressure often has no noticeable symptoms, which is why it is called the “silent killer.” Some people may experience headaches, shortness of breath, or nosebleeds, but these are not reliable indicators.
How to Measure Blood Pressure
Regular monitoring helps detect hypertension early.
- Use a validated cuff (manual or automatic)
- Sit quietly for 5 minutes before measurement
- Place the cuff on a bare upper arm at heart level
- Take two readings a minute apart and record the average
Lifestyle Changes to Lower Blood Pressure
Simple daily habits can make a big difference.
- Reduce salt: Aim for less than 5 g of salt per day.
- Eat a balanced diet: Include plenty of fruits, vegetables, whole grains, and low‑fat dairy (the DASH diet).
- Stay active: At least 150 minutes of moderate exercise weekly.
- Maintain healthy weight: Even a modest weight loss can lower pressure.
- Limit alcohol: No more than two drinks per day for men, one for women.
- Quit smoking: Tobacco raises blood pressure and damages vessels.
- Manage stress: Practice deep breathing, yoga, or meditation.
When to Seek Medical Help
If your readings consistently stay above 140/90 mm Hg, or you experience symptoms such as severe headache, chest pain, or vision changes, contact a doctor promptly.
