jnc 7 guidelines hypertension

Hypertension is a prevalent chronic condition. As per the JNC 7 guidelines, hypertension is typically diagnosed in adults when their blood pressure consistently exceeds 140/90 millimeters of mercury (mmHg). Diagnosis involves multiple blood pressure readings and an assessment that includes the patient's clinical symptoms and physical signs.

Hypertension is categorized into mild, moderate, and severe stages:

- Mild hypertension is defined as systolic blood pressure (SBP) between 140 and 159 mmHg and diastolic blood pressure (DBP) between 90 and 99 mmHg.

- Moderate hypertension is characterized by SBP between 160 and 179 mmHg and DBP between 100 and 109 mmHg.

- Severe hypertension is indicated by SBP of 180 mmHg or higher and DBP of 110 mmHg or higher.

Additionally, there is a specific condition known as isolated systolic hypertension, where SBP is 140 mmHg or higher and DBP is below 90 mmHg.

For individuals with hypertension, it is important to manage blood pressure through a low-sodium diet, regular physical activity, and stress reduction. Regular monitoring of blood pressure is crucial, and the use of antihypertensive medications should be under the guidance of a healthcare provider. Self-adjustment of medication or discontinuation without consultation is not advised. Persistent symptoms such as headaches and blurred vision should prompt a timely medical evaluation.
