Can Young Adults in the UK Get High Blood Pressure?
While high blood pressure is often associated with older age, it is increasingly being diagnosed in young adults across the UK. Modern lifestyle changes, including more sedentary habits and diets high in processed foods, have contributed to this shift. Because hypertension rarely causes symptoms, many young people remain unaware of their status, which can lead to long-term cardiovascular strain. This article explores why young adults are at risk, what the numbers mean for a younger demographic, and the importance of early detection to ensure long-term heart health.
What We’ll Discuss in This Article
- The rising prevalence of high blood pressure among UK young adults.
- Why hypertension is often missed in younger age groups due to a lack of symptoms.
- Primary lifestyle factors, such as diet and inactivity, affecting young people.
- The role of underlying medical conditions (secondary hypertension) in youth.
- Common triggers for temporary pressure spikes in university and workplace settings.
- Key differences between hypertension in young adults versus older populations.
- When and how young adults should seek blood pressure screenings.
High Blood Pressure Risk Among Younger Adults in the UK
Yes, young adults in the UK can and do get high blood pressure. While it is more common in those over 40, data suggests that a growing number of people aged 16 to 34 are being diagnosed with hypertension. In younger people, high readings are often linked to lifestyle factors like obesity and high salt intake, or occasionally to underlying health issues like kidney or hormonal disorders.
In the UK, the clinical definition of high blood pressure 140/90 mmHg in a clinic or 135/85 mmHg at home applies to all adults. For many young people, high blood pressure is discovered incidentally during a visit for another issue, such as a sports physical or a contraceptive pill review. Because the arteries of young adults are generally more elastic, they may tolerate high pressure for some time without symptoms, but the internal damage to the heart and blood vessels begins immediately.
Causes of High Blood Pressure in Young Adults
The causes of hypertension in young adults are typically split between lifestyle-driven factors and underlying medical conditions. While primary hypertension is increasingly common due to rising obesity rates, younger patients are statistically more likely than older adults to have secondary hypertension, where the high pressure is a symptom of another condition, such as a kidney problem.
Common causes for high readings in younger UK populations include:
- Overweight and Obesity: Carrying excess weight is the most significant modifiable risk factor for young people.
- Dietary Habits: High consumption of ultra-processed foods, fast food, and energy drinks often leads to salt intakes far exceeding the recommended 6g per day.
- Physical Inactivity: Spending long hours sitting for study or office-based work reduces cardiovascular fitness.
- Excessive Alcohol Consumption: Frequent ‘binge drinking’ can lead to sustained increases in blood pressure.
- Family History: Genetics play a strong role; if parents have hypertension, offspring are more likely to develop it early.
Common Triggers for Pressure Spikes in Young People
Young adults often encounter specific environmental and lifestyle triggers that cause temporary, sharp increases in blood pressure. While a single spike is not the same as chronic hypertension, frequent exposure to these triggers can make it difficult to get an accurate clinical reading and may contribute to long-term vascular stress.
Specific triggers common in the 18 to 35 age group include:
- Stress and Anxiety: Academic pressure, early-career stress, or financial worries can trigger the ‘fight or flight’ response.
- Caffeine and Stimulants: High intake of coffee or energy drinks during late-night study sessions or long shifts.
- Vaping and Smoking: Nicotine is a potent stimulant that causes immediate blood vessel constriction.
- Recreational Substances: Some substances can cause dangerous, acute elevations in blood pressure.
- The Contraceptive Pill: Some types of hormonal contraception can slightly increase blood pressure in some women.
Primary vs. Secondary Hypertension in Young Adults
In older adults, the vast majority of cases are primary hypertension (no single cause). However, in young adults especially those under 30 doctors are more likely to investigate for secondary hypertension. This is because high blood pressure in a young, otherwise fit person often points to an underlying issue that, if treated, could cure the hypertension.
| Feature | Primary (Essential) | Secondary (Underlying Cause) |
| Prevalence in Youth | Rising due to lifestyle factors | More common in youth than in elderly |
| Typical Causes | Weight, salt, inactivity, genetics | Kidney disease, heart defects, thyroid issues |
| Blood Pressure Level | Often moderately high | Can be very high and resistant to tablets |
| Management | Lifestyle changes and standard meds | Treating the underlying medical condition |
Conclusion
High blood pressure is no longer a condition that only affects the elderly. Young adults in the UK are increasingly at risk due to changing lifestyle patterns and environmental stressors. Because the condition is almost always symptomless, it is vital for young people to know their numbers, especially if they have a family history or are living with obesity. Early detection allows for lifestyle adjustments that can prevent serious heart issues in later life.
If you experience severe, sudden, or worsening symptoms such as chest pain, a sudden change in vision, or an unusual, severe headache, call 999 immediately.
How often should a 20-year-old check their blood pressure?
If you are healthy and have a normal reading, once every few years is usually enough, but you should have it checked whenever you visit a GP or pharmacy.
Can stress from university cause high blood pressure?
Stress can cause temporary spikes, but it usually only leads to long-term hypertension if it causes you to adopt unhealthy habits like poor diet or smoking.
Does vaping affect blood pressure in young adults?
Yes, the nicotine in vapes causes an immediate rise in heart rate and blood pressure and can damage artery walls over time.
Can the contraceptive pill cause high blood pressure?
Yes, some combined hormonal pills can raise blood pressure, which is why your GP or pharmacist will always check your pressure before prescribing them.
Is 130/80 mmHg high for a 25-year-old?
Can I grow out of high blood pressure?
You don’t usually ‘grow out’ of it, but if it is caused by being overweight or a poor diet, losing weight and eating less salt can often return your pressure to normal.
