What is high blood pressure?

High blood pressure (hypertension) usually has no symptoms but significantly increases the risk of heart attack, stroke, and kidney disease. It's often found during routine checks. Lifestyle changes — reducing salt, exercising, losing weight, and limiting alcohol — can lower blood pressure. Medication may be needed if lifestyle changes aren't enough.

When NHS resources suggest seeing a GP

  • You think you might have high blood pressure or are at risk.
  • You're aged 40 or over and haven't had your blood pressure checked in the last 5 years.
  • You have a family history of high blood pressure, heart disease, or stroke.
  • You're taking blood pressure medication and experiencing side effects.
  • Your home readings are consistently above 135/85 mmHg.

Self-care information from NHS

  • Reduce salt — aim for less than 6g a day (about a teaspoon).
  • Eat a balanced diet rich in fruit, vegetables, and wholegrains.
  • Exercise regularly — at least 150 minutes of moderate activity a week.
  • Lose weight if overweight — even a small loss makes a difference.
  • Limit alcohol to no more than 14 units a week.
  • Stop smoking — it raises blood pressure and damages arteries.
  • Reduce stress where possible and get enough sleep.

Common questions

What counts as high blood pressure?

A consistent reading of 140/90 mmHg or higher at a GP surgery (or 135/85 at home) is considered high. Blood pressure is usually checked several times to confirm, as single readings can be misleading.

Can I lower blood pressure without medication?

Yes — many people lower it through diet, exercise, weight loss, reducing salt, and limiting alcohol. If these changes aren't enough or your risk is high, medication (usually starting with a single tablet) may be recommended.

Do I need blood pressure medication for life?

Many people take it long-term, but some can reduce or stop after significant lifestyle changes. Never stop medication without your GP's advice — they'll review and adjust based on your readings.
