High blood pressure: the problem you cannot feel
High blood pressure is now one of the most common conditions we see in adults, and it is the one people find hardest to take seriously. That is because of one uncomfortable fact: for most people, it causes no symptoms at all until it has already done damage.
The short version: you cannot feel high blood pressure. The only way to know is to have it measured. If you are over 30, have it checked at least once a year.
What the numbers mean
A blood pressure reading has two numbers, for example 130/80. The first is the pressure when the heart beats, the second is the pressure when it rests between beats.
| Reading | What it means |
|---|---|
| Below 120/80 | Normal |
| 120–139 / 80–89 | Raised — worth changing habits and re-checking |
| 140/90 or above | High blood pressure, if it stays there on repeat visits |
| 180/110 or above | Go to a facility the same day |
One high reading does not mean you have hypertension. Blood pressure rises when you are anxious, in pain, or have just walked a long way. A diagnosis is made from readings taken on more than one occasion, sitting and rested.
Why it matters
Untreated high blood pressure quietly damages the blood vessels over years. It is a leading cause of stroke, heart failure and kidney failure. The person feels perfectly well the whole time — until the day they do not.
What helps
Salt
Most of the salt people eat is added during cooking or at the table. Reducing it is one of the most effective changes available and costs nothing. Watch for the hidden sources too: stock cubes, soup powders, crisps and preserved or tinned foods.
Weight and movement
Losing even a small amount of weight lowers blood pressure measurably. Thirty minutes of brisk walking most days is enough to make a difference — it does not require a gym.
Alcohol and tobacco
Both raise blood pressure. Stopping tobacco has the fastest effect on your overall risk of stroke and heart attack of anything on this list.
Medicine, if it is prescribed
Some people can control their pressure through habits alone. Many cannot, and need medication. Neither is a failure.
The mistake we see most often
Do not stop your medicine because you feel fine. Feeling fine is what the medicine is doing. Blood pressure treatment is usually for life.
People often stop when the tablets run out, when they feel well, or when money is short. Blood pressure then climbs back up silently within weeks. If cost or side effects are the problem, say so at the clinic — there are usually alternatives. Stopping without telling anyone is the worst option.
Get checked if
- You are over 30 and have not had a reading in the last year
- A parent or sibling has high blood pressure, diabetes, or had a stroke
- You are pregnant — blood pressure is checked at every antenatal visit for good reason
- You get frequent headaches, blurred vision, or shortness of breath on light activity
