High blood pressure, or hypertension, is characterized by consistently elevated blood pressure levels in the arteries, increasing the risk of serious health conditions, including heart disease and stroke. It often develops over time, influenced by factors like poor diet, lack of physical activity, obesity, and genetics. Monitoring and managing blood pressure through lifestyle modifications or medication can help reduce the likelihood of complications. Regular exercise, a balanced diet low in sodium, and stress management are vital strategies to control hypertension effectively.
