Hypertension, also known as high blood pressure, refers to a condition where the pressure of the blood against the walls of the arteries remains consistently elevated. Blood pressure is measured in millimeters of mercury (mmHg) and is recorded with two numbers: systolic pressure (during a heartbeat) over diastolic pressure (between heartbeats). A normal reading is usually around 120/80 mmHg, while hypertension is generally defined as having readings of 130/80 mmHg or higher (National Heart, Lung, and Blood Institute, 2024).

High blood pressure can be caused by various factors, including genetic predisposition, unhealthy lifestyle choices (such as poor diet, lack of exercise, and smoking), obesity, excessive alcohol consumption, stress, and certain medical conditions (such as kidney disease and hormonal disorders). In many cases, the exact cause is not identified, which is referred to as primary hypertension (National Kidney Foundation, 2024).

High blood pressure often goes unnoticed because it typically has no readily apparent symptoms. This is why it’s known as the “silent killer.” While some individuals might report headaches, difficulty breathing, or nosebleeds, these symptoms typically occur only when blood pressure reaches critically high levels. Regular monitoring is essential for detection (Felman, 2023).

High blood pressure is diagnosed using a blood pressure cuff and a sphygmomanometer during a medical examination. A healthcare professional will take several readings over time to confirm the diagnosis, as blood pressure can fluctuate throughout the day (Mayo Clinic, 2024).

High blood pressure can lead to serious health problems, including heart disease, stroke, kidney damage, and vision loss. It may also lead to additional cardiovascular problems and raise the likelihood of developing metabolic syndrome, type 2 diabetes, and various other chronic illnesses (Alabama Public Health, 2021).

Managing high blood pressure usually requires lifestyle modifications and, in certain situations, the use of medication. Lifestyle modifications may include adopting a healthier diet (such as the DASH diet), increasing physical activity, reducing sodium intake, limiting alcohol consumption, quitting smoking, and managing stress. Medications may include diuretics, ACE inhibitors, beta-blockers, or calcium channel blockers, depending on individual needs (Mayo Clinic, 2024).

While not all cases of high blood pressure can be prevented, many risk factors can be managed through healthy lifestyle choices. Maintaining a balanced diet, exercising regularly, maintaining a healthy weight, managing stress, and avoiding tobacco use can help reduce the risk of developing hypertension (Medline Plus, 2019).

Adults ought to have their blood pressure assessed at least once every two years if their measurements are within the normal range (below 120/80 mmHg). Those with higher readings or risk factors for hypertension should check their blood pressure more frequently, as recommended by their healthcare provider (Heart-Healthy Living – Get Your Blood Pressure and Cholesterol Checked | NHLBI, NIH, n.d.).

Yes, there are many home blood pressure monitors available that are easy to use. It is crucial to adhere to the manufacturer’s guidelines diligently and to take measurements at the same time each day for the most precise results. Regularly tracking your blood pressure at home can help you and your healthcare provider manage your condition effectively.

You should consult a healthcare professional if you have consistently elevated blood pressure readings (130/80 mmHg or higher) or if you experience any unusual symptoms such as severe headaches, dizziness, or chest pain. Regular check-ups can also help in early detection and management of high blood pressure.
