The top number (systolic) is the pressure when your heart beats. The bottom (diastolic) is the pressure between beats. The American College of Cardiology lowered the threshold from 140\/90 to 130\/80 in 2017 because research showed damage begins at lower levels.<\/p>\n
Why It Matters<\/h2>\n
High blood pressure damages blood vessels over years, leading to:<\/p>\n
- \n
- Heart attack:<\/strong> Narrowed arteries reduce blood flow to the heart muscle.<\/li>\n
- Stroke:<\/strong> A weakened vessel bursts or a clot blocks blood flow to the brain.<\/li>\n
- Heart failure:<\/strong> The heart muscle thickens and weakens from working too hard.<\/li>\n
- Kidney disease:<\/strong> Damaged vessels in the kidneys reduce filtration.<\/li>\n
- Vision loss:<\/strong> Blood vessels in the retina rupture.<\/li>\n
- Sexual dysfunction:<\/strong> Reduced blood flow.<\/li>\n
- Peripheral artery disease:<\/strong> Leg pain while walking.<\/li>\n<\/ul>\n
Risk Factors You Cannot Change<\/h2>\n
- \n
- Age:<\/strong> Risk rises after 65; systolic pressure often climbs.<\/li>\n
- Family history:<\/strong> Genetics account for about 30-40% of risk.<\/li>\n
- Race:<\/strong> Black adults develop hypertension earlier and more severely.<\/li>\n
- Sex:<\/strong> Men under 55 are at higher risk; women after menopause catch up.<\/li>\n<\/ul>\n

The DASH (Dietary Approaches to Stop Hypertension) trial showed that this eating plan lowers BP by 8-14 mmHg \u2014 comparable to some medications. Key principles:<\/p>\n
- \n
- 4-5 servings of fruit per day.<\/li>\n
- 4-5 servings of vegetables per day.<\/li>\n
- 2-3 servings of low-fat dairy.<\/li>\n
- Whole grains instead of refined.<\/li>\n
- Lean protein: fish, poultry, beans (limited red meat).<\/li>\n
- Low saturated fat, added sugar and sodium.<\/li>\n
- 4-5 servings of nuts per week.<\/li>\n<\/ul>\n
Exercise and Blood Pressure<\/h2>\n
The ACSM recommends 150 minutes per week of moderate aerobic exercise. Benefits:<\/p>\n
- \n
- Lowers resting BP by 5-8 mmHg within a few weeks.<\/li>\n
- Improves blood vessel elasticity.<\/li>\n
- A single 30-minute walk lowers BP for hours afterward.<\/li>\n
- Combine with 2 days of strength training (which also helps).<\/li>\n<\/ul>\n
Monitoring at Home<\/h2>\n
Home blood pressure monitors cost $40-80 and are more accurate than clinic readings (which can spike due to white-coat hypertension). Tips:<\/p>\n

<\/p>\n- \n
- Sit quietly for 5 minutes before measuring.<\/li>\n
- Arm supported at heart level, feet flat on floor.<\/li>\n
- No caffeine, exercise or smoking 30 minutes before.<\/li>\n
- Take 2 readings 1 minute apart; record the average.<\/li>\n
- Measure at the same time each day (morning and evening).<\/li>\n
- Bring the log to your doctor.<\/li>\n<\/ul>\n
Medication<\/h2>\n
Lifestyle changes work, but many people also need medication. Common classes: diuretics, ACE inhibitors, ARBs, calcium channel blockers. Take them as prescribed \u2014 even if you feel fine. High BP has no symptoms, but untreated it silently damages organs. Do not stop medication without talking to your doctor.<\/p>\n
Common Myths<\/h2>\n
Myth:<\/strong> High blood pressure causes headaches or nosebleeds.
\nReality:<\/strong> Usually no symptoms at all. Severe hypertension may cause headaches, but mild-to-moderate levels are silent.<\/p>\nMyth:<\/strong> I would know if my blood pressure was high.
\nReality:<\/strong> One in 7 adults with high BP does not know they have it.<\/p>\nMyth:<\/strong> Once it is controlled, I can stop medication.
\nReality:<\/strong> Blood pressure rises again without treatment. Medication is a long-term management tool, not a cure.<\/p>\nFrequently Asked Questions<\/h2>\n
Q: What should my blood pressure be?<\/strong>
\nBelow 120\/80 mmHg. If your reading is consistently 130\/80 or higher, see your doctor.<\/p>\nQ: Is it normal for BP to fluctuate?<\/strong>
\nYes, throughout the day. Stress, caffeine, exercise and sleep affect it. What matters is the average over many readings.<\/p>\nQ: Can I reverse high blood pressure without medication?<\/strong>
\nMild hypertension (130-139\/80-89) may improve with lifestyle changes. Stage 2 usually requires medication plus lifestyle.<\/p>\nQ: Does caffeine raise blood pressure permanently?<\/strong>
\nIt causes a temporary spike (5-10 mmHg for a few hours). Regular drinkers develop tolerance. Limit to 2-3 cups\/day.<\/p>\nQ: What about decongestants?<\/strong>
\nMany cold medicines (pseudoephedrine, phenylephrine) raise BP. Ask your pharmacist for BP-safe alternatives.<\/p>\nQ: How often should I check?<\/strong>
\nNormal: every 1-2 years. Elevated: every 3-6 months. On medication: as your doctor recommends, often weekly.<\/p>\nReferences<\/h2>\n
