High blood pressure can increase strain on the heart, kidneys, brain, and blood vessels if it remains uncontrolled for a long time. Stress, excess salt intake, obesity, poor sleep, smoking, alcohol, lack of exercise, diabetes, and family history commonly contribute to persistently raised blood pressure. Blood pressure control usually improves with a combination of medicines and lifestyle changes. Reducing salt, packaged foods, fried food, smoking, and alcohol may help lower blood pressure gradually. Regular walking, weight control, stress reduction, proper sleep, and eating fruits, vegetables, whole grains, and potassium-rich foods may also support better heart health. Taking blood pressure medicines regularly and monitoring readings at home can help maintain more stable control. Sudden severe headache, chest pain, breathlessness, dizziness, blurred vision, or very high blood pressure readings can suggest the pressure is affecting the body more significantly and may need proper medical attention and treatment adjustment.
