Understanding your blood pressure numbers

What 130/85 actually means, why one high reading is not a diagnosis, and when to see a cardiologist.

Blood pressure is written as two numbers. The first, systolic, is the pressure in your arteries when the heart beats; the second, diastolic, is the pressure between beats. A reading of 120/80 mmHg is the classic reference point, but what matters is your pattern over time, not a single measurement taken after climbing the stairs to the clinic.

The categories

Most guidelines used in the Gulf and Egypt follow similar bands. Normal is below 120/80. Elevated, or high-normal, is 120–129 systolic with diastolic under 80. Stage 1 hypertension starts at 130/80 and stage 2 at 140/90. Anything above 180/120 with symptoms such as headache, chest pain or vision change is a hypertensive emergency and needs immediate care.

Why one reading is not enough

Blood pressure rises with pain, anxiety, caffeine, a full bladder and talking during the measurement. "White-coat hypertension", where readings are high only in the clinic, is common. That is why doctors ask for home readings before diagnosing: sit quietly for five minutes, feet flat, arm supported at heart level, cuff on bare skin, and take two readings a minute apart in the morning and evening for seven days. Discard the first day and average the rest.

Why it matters even when you feel fine

Sustained high pressure quietly damages the arteries of the heart, brain, kidneys and eyes. It is the leading modifiable risk factor for stroke and a major contributor to heart failure and kidney disease. Because it rarely causes symptoms, the only way to know is to measure.

What brings it down

Losing five kilograms can lower systolic pressure by around five points. Reducing salt to under five grams a day, limiting processed foods, thirty minutes of brisk walking most days, cutting back on alcohol and stopping smoking each make a measurable difference. When lifestyle changes are not enough, modern medicines are safe, inexpensive and usually taken once a day. Many people need two medicines at low doses rather than one at a high dose, which reduces side effects.

When to book a cardiologist

See a doctor if your home average is 135/85 or higher, if readings vary widely, if you have diabetes or kidney disease, or if you are under forty with high readings, because a treatable underlying cause is more likely. Bring your home log; it is the most useful thing you can hand over.
