Hypertension-1, also known as Stage 1 Hypertension, is a condition where blood pressure consistently ranges between 130-139 mmHg systolic or 80-89 mmHg diastolic. It is an early stage of high blood pressure and a significant risk factor for heart disease, stroke, and other cardiovascular complications. Common causes include stress, obesity, high salt intake, lack of exercise, smoking, and genetic predisposition. While it may not cause noticeable symptoms, prolonged hypertension can damage blood vessels and organs over time. Management typically involves lifestyle changes such as a healthy diet, regular physical activity, stress reduction, and, in some cases, medication. Early detection and control are crucial to prevent progression to Stage 2 Hypertension or severe complications. Regular monitoring and medical guidance are recommended for maintaining optimal blood pressure levels.
