High blood pressure, or hypertension, is a prevalent condition affecting millions globally, often without obvious symptoms. Dr. Dhruv Zutshi, Additional Director of Neurology at Fortis Hospital Vasant Kunj, emphasizes that hypertension is a 'silent killer' because it can lead to severe complications like stroke and heart disease before any warning signs appear. The condition develops gradually, allowing the body to adapt to rising blood pressure levels, which can mask symptoms for years. Many individuals only discover their hypertension after experiencing serious health issues, such as heart attacks or kidney disease. Risk factors include age, obesity, diabetes, and a sedentary lifestyle. Regular blood pressure monitoring is vital, especially for those at higher risk, as it is the only reliable method for early detection. Experts recommend lifestyle modifications, including a balanced diet, regular exercise, and stress management, to maintain healthy blood pressure levels. Overall, awareness and proactive health checks are essential to combat the silent threat of hypertension.
