What the Two Numbers Mean<\/em><\/h2>\n

A blood pressure reading is written as two numbers, one over the other. Each number measures something different about how your heart is working.<\/p>\n\n

\n Systolic<\/b> (the top number) measures the pressure in your arteries when your heart beats and pumps blood out. Diastolic<\/b> (the bottom number) measures the pressure in your arteries while your heart rests between beats. Both matter, a reading isn’t complete with just one.\n <\/div>\n <\/section>\n\n \n
\n

The Blood Pressure Categories<\/em><\/h2>\n

Once you have a reading, here’s what each range generally means:<\/p>\n\n

\n
\n

\u6b63\u5e38<\/p>\n

Systolic below 120 and<\/em> diastolic below 80. In practice: keep up your regular check-ins.<\/p>\n <\/div>\n

\n

\u5347\u9ad8\u5497<\/p>\n

Systolic 120\u2013129 and<\/em> diastolic below 80. In practice: this is a signal worth acting on early. Small, sustained changes now (activity, sodium, sleep) can help keep it from progressing.<\/p>\n <\/div>\n

\n

Stage 1 Hypertension<\/p>\n

Systolic 130\u2013139 or<\/em> diastolic 80\u201389. In practice: worth discussing with your care team. Lifestyle changes are typically the first step, sometimes alongside medication depending on your overall risk.<\/p>\n <\/div>\n

\n

Stage 2 Hypertension<\/p>\n

Systolic 140 or higher or<\/em> diastolic 90 or higher. In practice: your care team may recommend starting treatment, usually combining lifestyle changes with medication.<\/p>\n <\/div>\n

\n

\u9ad8\u8840\u58d3\u5371\u6a5f<\/p>\n

Systolic above 180 and\/or<\/em> diastolic above 120. In practice: if you have symptoms like chest pain, shortness of breath, or vision changes, this needs emergency care right away.<\/p>\n

\n

Why Both Numbers Matter<\/em><\/h2>\n

More attention is often given to the systolic (top) number, since it’s a stronger predictor of heart disease risk for people over 50, as arteries naturally stiffen with age. But high diastolic pressure carries risk too, and a diagnosis is based on whichever number, systolic or diastolic, falls into the higher category.<\/p>\n

A single reading also isn’t the full picture. Blood pressure naturally fluctuates through the day, so a diagnosis is usually based on the average of two or more readings taken on separate occasions, not one number in isolation.<\/p>\n <\/section>\n\n \n
