High blood pressure, or hypertension, is often thought of as something that happens to people over 50. The reality is different. Hypertension in young adults between the ages of 18 and 40 is becoming more common, driven by changing lifestyles, rising rates of obesity, and increased stress. Because it causes no obvious symptoms in most cases, it frequently goes undiagnosed for years, quietly damaging the heart, kidneys, and blood vessels.
What blood pressure reading is considered high?
Blood pressure is measured in millimetres of mercury (mmHg) as two numbers. A reading below 120 over 80 is normal. A reading of 130 to 139 over 80 to 89 is classified as Stage 1 hypertension. A reading of 140 or above over 90 or above is Stage 2 hypertension. A reading of 180 over 120 or higher is a hypertensive crisis that requires immediate medical attention.
What causes high blood pressure in young people?
- Overweight and obesity: excess body fat increases the workload on the heart and raises blood pressure
- High salt intake from ultra-processed foods, fast food, and packaged snacks
- Chronic stress from work, academic pressure, or relationship difficulties
- Sedentary lifestyle with little or no regular physical activity
- Excessive alcohol consumption
- Smoking or tobacco use in any form
- Secondary causes including kidney disease, thyroid disorders, or hormonal conditions such as polycystic ovary syndrome (PCOS) or adrenal gland problems
- A family history of hypertension or early heart disease
Does high blood pressure cause symptoms?
Most of the time, no. Hypertension is called the silent killer because the majority of people with it feel completely normal. When symptoms do occur they may include headaches at the back of the head, particularly in the morning, dizziness, visual changes, or a feeling of pressure behind the eyes. These symptoms typically appear only when blood pressure is very high. The only reliable way to know your blood pressure is to measure it.
Why is hypertension dangerous even without symptoms?
Sustained high blood pressure damages arteries over time, increasing the risk of heart attack, stroke, heart failure, kidney failure, and vision loss. Young adults who develop hypertension and leave it untreated have decades of arterial damage ahead of them. Early detection and management significantly reduce these risks.
How is hypertension managed in young adults?
For young adults with Stage 1 hypertension and no other risk factors, the first approach is lifestyle change: reducing salt, increasing exercise, losing weight if needed, quitting tobacco, and limiting alcohol. If blood pressure does not respond adequately after three to six months, or if Stage 2 hypertension is present, medication is typically recommended alongside lifestyle measures. Your doctor will also look for secondary causes that may be treatable.
How often should young adults check their blood pressure?
Adults from the age of 18 should have their blood pressure checked at least once every two years if it is normal. If you have a family history of hypertension, heart disease, or kidney disease, annual checks are more appropriate. If you have any risk factors or a reading above 120 over 80, more frequent monitoring is recommended.
