jnc 8 hypertension classification

The United States Hypertension Prevention and Treatment Guidelines (JNC 8) classify blood pressure into four categories: normal, elevated, stage 1 hypertension, and stage 2 hypertension. Normal blood pressure is characterized by a systolic pressure below 120 mm Hg and a diastolic pressure below 80 mm Hg. Elevated blood pressure is defined as a systolic pressure ranging from 120 to 129 mm Hg with a diastolic pressure under 80 mm Hg. Stage 1 hypertension is diagnosed when the systolic pressure is between 130 and 139 mm Hg or the diastolic pressure is between 80 and 89 mm Hg. Stage 2 hypertension is identified by a systolic pressure of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher.

To prevent and manage hypertension in daily life, individuals should adopt a healthy lifestyle, which includes regular physical activity, a balanced diet, limiting salt and alcohol consumption, abstaining from smoking, and maintaining a healthy weight. Patients diagnosed with hypertension must adhere to lifestyle modifications and follow their physician's recommendations, including taking antihypertensive medications as prescribed and monitoring their blood pressure regularly. It is crucial not to discontinue or alter the dosage of medications without medical advice to prevent blood pressure fluctuations and the associated risk of cardiovascular events.

In conclusion, being aware of one's blood pressure status and taking appropriate preventive and therapeutic actions is essential. If you have any inquiries or concerns regarding hypertension, promptly seek advice from a healthcare professional to ensure you receive accurate guidance and support.
