Introduction
Hypertension, commonly known as high blood pressure, has traditionally been associated with older adults. However, recent trends indicate a disturbing rise in hypertension among young adults, particularly millennials aged 29 to 44 (people born between 1981 and 1996). This shift is attributed to various lifestyle factors, including increased consumption of processed foods and beverages high in added sugars. This article explores the underlying causes of this trend, emphasizing the role of hidden sugars in contributing to heart disease and hypertension. It also summarises an article which was published on BBC website in 2023, which described a problem of elevated blood pressure even in younger people, age 16 to 24 (https://www.bbc.co.uk/news/health-65410018). Finally, it also answers several interesting questions about blood pressure for instance if salt and liquorice have impact on our blood pressure levels.
Understanding Hypertension
Hypertension is a condition characterized by persistently elevated blood pressure levels, which can lead to severe health complications such as heart disease, stroke, and kidney failure. Blood pressure is measured in millimetres of mercury (mm Hg) and recorded with two numbers: systolic pressure (pressure during heartbeats) over diastolic pressure (pressure between heartbeats). A normal reading is typically around 120/80 mm Hg. Definition of hypertension below.
What is Sustained (Real) Hypertension?
Sustained hypertension—also known as real hypertension—is a long-term condition where an individual consistently has elevated blood pressure, both in clinical settings and during everyday life. Unlike White Coat Hypertension, which occurs only in medical environments due to anxiety, sustained hypertension reflects a constant strain on the cardiovascular system.
Accurate diagnosis is essential, as this form of hypertension significantly increases the risk of heart disease, stroke, and other serious health complications.
Understanding Blood Pressure Categories
✅ Normal Blood Pressure
- Optimal: Between 90/60 mmHg and 120/80 mmHg.
- For individuals over 80, ideal readings are:
- Below 150/90 mmHg in a clinic setting
- Below 145/85 mmHg at home
(This accounts for age-related changes, like stiffening of arteries.)
⚠️ High-Normal (Pre-Hypertension)
- Ranges from 120/80 mmHg to 140/90 mmHg
- Not yet classified as hypertension but considered a warning sign
- A healthy lifestyle at this stage can prevent progression to full-blown hypertension
High Blood Pressure (Hypertension) Stages
🔴 Stage 1 Hypertension
- Clinic reading: 140/90 to 160/100 mmHg
- Home reading: 135/85 to 150/95 mmHg
🔴 Stage 2 Hypertension
- Clinic reading: 160/100 to 180/120 mmHg
- Home reading: Over 150/95 mmHg
🔴 Stage 3 Hypertension (Severe)
- Systolic: Over 180 mmHg
- Diastolic: Over 120 mmHg

Rising Prevalence Among Millennials
Recent studies have shown an alarming increase in hypertension cases among young adults. This demographic shift is concerning because early-onset hypertension can lead to prolonged exposure to high blood pressure, increasing the risk of cardiovascular diseases over time. Factors contributing to this trend include sedentary lifestyles, poor dietary habits, increased stress levels, and higher consumption of processed foods and sugary beverages.
The Role of Hidden Sugars in Heart Disease
One of the significant contributors to hypertension and heart disease is the high intake of added sugars, often hidden in processed foods and beverages. These “hidden sugars” can be found in items not typically associated with sweetness, such as bread, sauces, and canned soups. Excessive sugar intake has been linked to various health issues, including obesity, insulin resistance, and increased blood pressure—all risk factors for heart disease.
A study published in the Journal of Clinical Endocrinology & Metabolism found that adults consuming high levels of fructose or high-fructose corn syrup exhibited increased levels of LDL cholesterol, triglycerides, and apolipoprotein-B, all of which are associated with an elevated risk of cardiovascular disease.

Sugar Intake and Heart Health
The relationship between sugar intake and heart health is well-documented. High consumption of added sugars can lead to increased blood pressure, inflammation, weight gain, diabetes, and fatty liver disease, all of which are linked to an elevated risk of heart attack and stroke.
The American Heart Association recommends that women limit their intake of added sugars to no more than 100 calories per day (about 6 teaspoons), and men to no more than 150 calories per day (about 9 teaspoons). However, many individuals exceed these recommendations, often unknowingly, due to the prevalence of hidden sugars in processed foods. The American Heart Association’s official page on added sugars has more detailed information.

Sugar Consumption and Heart Disease
Several studies have established a direct link between sugar consumption and heart disease. BMC Medicine Study on Free Sugars and Cardiovascular Risk: A large-scale study published in BMC Medicine analyzed data from over 110,000 UK participants aged 37 to 73 over nine years. The researchers found that for every 5% increase in total energy intake from free sugars, there was a:
- 7% higher risk of total cardiovascular disease
- 6% higher risk of heart disease
- 10% higher risk of stroke These findings highlight the significant impact of free sugar consumption on cardiovascular health.
JAMA Internal Medicine Study on Added Sugar and Heart Disease Mortality: A study published in JAMA Internal Medicine examined the relationship between added sugar intake and cardiovascular disease mortality among U.S. adults. The study concluded that individuals consuming 25% or more of their daily calories from added sugars had a 2.75 times higher risk of dying from heart disease compared to those who consumed less than 10%. This research underscores the critical importance of moderating added sugar intake to reduce the risk of cardiovascular mortality.

Lifestyle Factors Contributing to Hypertension in Millennials
Sedentary Lifestyle
The modern lifestyle, characterized by prolonged periods of sitting due to desk jobs and screen time, contributes to the development of hypertension. Physical inactivity can lead to weight gain, reduced insulin sensitivity, and increased blood pressure.
Poor Dietary Habits
Millennials often rely on convenience foods, which are typically high in sodium, unhealthy fats, and added sugars. These dietary choices contribute to the development of hypertension and other cardiovascular diseases.
Stress and Mental Health
Chronic stress, common among young adults due to work pressures and financial concerns, can lead to unhealthy coping mechanisms such as overeating, smoking, or excessive alcohol consumption—all risk factors for hypertension.
Preventive Measures and Recommendations
Dietary Changes
- Reduce Added Sugar Intake: Be vigilant about reading food labels to identify hidden sugars. Choose natural sweeteners and limit consumption of sugary beverages.
- Adopt the DASH Diet: The Dietary Approaches to Stop Hypertension (DASH) diet emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy, while limiting foods high in saturated fat and sugar.
Increase Physical Activity
Engage in at least 150 minutes of moderate-intensity aerobic activity per week, such as brisk walking, cycling, or swimming. Regular exercise helps lower blood pressure and improves overall cardiovascular health.
Manage Stress
Incorporate stress-reducing practices into daily routines, such as mindfulness meditation, deep breathing exercises, or yoga. Seeking professional help when needed can also be beneficial.
Regular Health Screenings
Regular monitoring of blood pressure and cholesterol levels can aid in early detection and management of hypertension. Early intervention is crucial in preventing long-term health complications.
Undiagnosed Hypertension in Young People
This section is based on the article published on the BBC website in April 2023, https://www.bbc.co.uk/news/health-65410018. It informed the public about the fact that thousands of young people in England live with undiagnosed high blood pressure.
A significant number of young people in England—approximately 170,000 individuals aged 16 to 24—are unknowingly living with dangerously high blood pressure, according to analysis by the Office for National Statistics (ONS).
This translates to around five in every 100 young men and one in every 100 young women, highlighting a growing but often overlooked public health concern. Despite the absence of immediate symptoms in many cases, hypertension—the medical term for high blood pressure—places continuous strain on the heart and blood vessels. Over time, this silent condition can lead to life-threatening complications such as heart attacks, strokes, kidney disease, and vascular dementia.
In fact, hypertension is responsible for nearly half of all heart attacks and strokes in the UK, making early detection and management critical. What’s particularly concerning is that high blood pressure can develop at any age, contradicting the common belief that it only affects the elderly.
Approximately one in three adults in the UK has high blood pressure, yet many remain unaware of their condition, according to health experts.
Several lifestyle factors contribute to elevated blood pressure, including being overweight, following an unhealthy diet, physical inactivity, excessive alcohol consumption, and smoking. These risk factors can place additional strain on the heart and arteries, often without producing noticeable symptoms—making routine blood pressure checks essential for early detection and prevention.
This lack of awareness among young people is a major barrier to early intervention. The new ONS findings, derived from the Health Survey for England, included at-home blood pressure readings taken from more than 20,000 participants, including 1,500 young people. Readings were taken on multiple occasions by nurses to ensure accuracy, providing one of the most reliable assessments to date.
Startling Statistics: The Hidden Epidemic
The analysis found that:
- 7% of men (roughly 210,000) and 4% of women (around 110,000) aged 16–24 in England have high blood pressure.
- Of these, a staggering 66% of young men and 26% of young women were completely unaware of their condition.
- Comparatively, only 17% of men and 21% of women aged 75 and over were undiagnosed—underscoring the younger population’s vulnerability due to limited healthcare engagement.
This data paints a clear picture: young people are not exempt from cardiovascular risk. In fact, their lack of symptoms and interaction with healthcare services makes them even more vulnerable to undetected and unmanaged hypertension.

A Global Perspective on Hypertension
- Global Prevalence: The World Health Organization (WHO) reports that approximately 1.28 billion adults aged 30–79 years worldwide have hypertension. Notably, about 46% of these individuals are unaware of their condition.
- Paraguay’s High Rates: In 2019, Paraguay had one of the highest hypertension prevalence rates globally, with 62% of men and 51% of women affected.
- Lower Rates in Canada and Peru: Countries like Canada and Peru have some of the lowest hypertension prevalence rates, with 20% or fewer adults affected.

Frequently Asked Questions About Hypertension: What the Latest Research Tells Us
1. How Many People Globally Are Affected by High Blood Pressure?
According to a 2023 World Health Organization (WHO) report, an estimated 1.3 billion people worldwide are currently living with hypertension—a number that has doubled over the past 30 years. Alarmingly, 78% of those affected reside in low- and middle-income countries, where access to healthcare and preventive strategies may be limited.
Despite its prevalence, only about 20% of diagnosed individuals have their blood pressure adequately controlled. While high blood pressure is often asymptomatic, it can occasionally manifest with headaches, chest pain, dizziness, breathlessness, or blurred vision. Left untreated, it significantly raises the risk of heart attacks, strokes, heart failure, kidney disease, peripheral vascular disease, and vascular dementia.
https://jamanetwork.com/journals/jama/article-abstract/2810574
2. Does Frequent Mobile Phone Use Increase the Risk of Hypertension?
Surprisingly, yes. A 2023 study published in European Heart Journal – Digital Health linked prolonged mobile phone use to elevated hypertension risk. Using UK Biobank data from over 200,000 participants without prior hypertension, researchers observed a trend: those who spent 30+ minutes per week on phone calls had significantly higher risks of developing high blood pressure.
Key findings included:
- 30–59 mins/week: 8% higher risk (HR 1.08)
- 1–3 hrs/week: 13% higher risk (HR 1.13)
- 4–6 hrs/week: 16% higher risk (HR 1.16)
- 6+ hrs/week: 25% higher risk (HR 1.25)
https://academic.oup.com/ehjdh/article/4/3/165/7131479?login=false
3. Is Ultra-Processed Food Linked to High Blood Pressure?
Yes. A 2022 meta-analysis in the American Journal of Hypertension reviewed data from 111,594 participants across nine international studies. The analysis found that ultra-processed food consumption was associated with a 23% higher risk of developing hypertension (Odds Ratio 1.23; 95% CI: 1.11–1.37; p=0.034).
Ultra-processed foods include:
- Packaged snacks
- Pastries and cakes
- Frozen pizzas
- Processed meats and fast food
https://academic.oup.com/ajh/article/35/10/892/6617679
4. Does Duration of Hypertension Matter?
Yes, the longer you live with high blood pressure, the higher your risk of cardiovascular complications—even if your blood pressure is currently controlled. A large-scale UK study (n = 450,000) published in Frontiers in Cardiovascular Medicine found a linear relationship between hypertension duration and risk of heart attack, stroke, or death from any cause.
“These associations were independent of the blood pressure levels achieved,” the authors noted.
https://www.frontiersin.org/articles/10.3389/fcvm.2022.948707/full
5. How Does Salt Intake Affect Blood Pressure?
A 2023 JAMA clinical trial demonstrated that even one week on a low-sodium diet (500 mg/day) significantly reduced blood pressure by 8 mmHg compared to a high-sodium diet (2,200 mg/day). The study included over 200 adults aged 50–75, with diverse blood pressure statuses.
Notably, 75% of participants saw improvements—similar to the effect of a first-line antihypertensive drug.
https://jamanetwork.com/journals/jama/article-abstract/2811931
6. Can Liquorice Raise Your Blood Pressure?
Yes. A 2024 study in the American Journal of Clinical Nutrition found that consuming 100 mg of glycyrrhizic acid (GA) from liquorice significantly raised blood pressure in healthy young adults.
Key results:
- BP increased by 3.1 mmHg in the liquorice group
- Control group showed no significant change
- Hormonal changes included suppressed renin and aldosterone and elevated NT-proBNP in some participants
Researchers suggest revising the WHO safety limit for GA intake.

7. Is Snoring Linked to High Blood Pressure?
Yes, according to a 2024 study in NPJ Digital Medicine, frequent snoring—even without sleep apnea—is linked to significantly higher risks of uncontrolled hypertension. Data from over 12,000 adults (average age 50) showed that those who snored regularly had:
- A 1.9x higher risk of uncontrolled hypertension
- Average increases of 3 mmHg systolic and 4 mmHg diastolic pressure
This association was independent of age, BMI, and apnea severity.

Conclusion
The increasing prevalence of hypertension among millennials and even younger adults is a pressing public health concern. Lifestyle factors, particularly the consumption of hidden sugars, play a significant role in this trend. By making informed dietary choices, engaging in regular physical activity, and managing stress effectively, young people can mitigate the risk of developing hypertension and associated cardiovascular diseases. Awareness and proactive measures are key to reversing this alarming trend and promoting heart health among the younger population.
