The pharmacy kiosk shows 168/104, and the home cuff you bought for your father reads even higher. A high blood pressure reading is unsettling, and the next step depends first on whether anyone feels unwell, then on how high the numbers are. Here is how families in National City can tell an emergency from a visit that can happen soon, and how to get a reading you can trust.
Blood Pressure Numbers Explained
The top number (systolic) is the pressure in your arteries when your heart beats. The bottom number (diastolic) is the pressure between beats. The National Heart, Lung, and Blood Institute (NHLBI) groups adult readings this way:
- Normal: top number below 120 and bottom number below 80
- Elevated: 120 to 129 on top and below 80 on the bottom
- Stage 1 high blood pressure: 130 to 139 on top, or 80 to 89 on the bottom
- Stage 2 high blood pressure: 140 or higher on top, or 90 or higher on the bottom
- Hypertensive crisis: higher than 180 on top, or higher than 120 on the bottom
Only one number has to fall in a range for the reading to count. The CDC reports that nearly half of U.S. adults (48.1%) have high blood pressure, and about 1 in 6 of them do not know it. Because it usually has no symptoms, a number on a screen is often the first clue.
Emergency Symptoms With High Blood Pressure: Call 911
Call 911 right away, without waiting to recheck, if you have sudden chest pain, trouble breathing, numbness or weakness, trouble speaking, a sudden change in vision or a sudden severe headache, whatever your reading. These can be warning signs of a heart attack or a stroke, and the CDC says to call 911 right away for either one. Watch for:
- Sudden chest pain or discomfort, or sudden severe pain in the back or abdomen
- Trouble breathing or shortness of breath
- Numbness or weakness in the face, arm or leg, especially on one side
- Trouble speaking or understanding speech
- A sudden change in vision
- A sudden, severe headache
The NHLBI names these symptoms as reasons to call 911 when blood pressure is very high, and warns that pressure this high can damage your organs. Do not stop to recheck, and call 911 rather than driving yourself. These symptoms need emergency care, not urgent care. For other situations, our guide to urgent care vs. the emergency room walks through common examples.
High Blood Pressure Reading Without Symptoms: Recheck and Get Evaluated
Most high numbers arrive with no warning signs. If you feel fine but the top number is 180 or higher, or the bottom number is 120 or higher (either one alone counts), the NHLBI recommends waiting five minutes and checking again. If the second reading is still that high, call your healthcare provider right away. They may recommend starting a medicine or changing your dose. If any symptom from the list above appears while you wait, call 911.
Below crisis level, for example 150/95, one reading is not a diagnosis. MedlinePlus notes that blood pressure normally varies with the time of day, and the NHLBI says a diagnosis takes two or more readings at separate appointments. Repeated stage 2 numbers still deserve a prompt visit, so log careful home readings and bring them in.
How to Take an Accurate Reading at Home
MedlinePlus says home readings may be a better measure of your current blood pressure than office readings, but technique matters. The CDC and MedlinePlus recommend these steps:
- For 30 minutes beforehand, skip food, drinks, caffeine, smoking and exercise.
- Empty your bladder.
- Sit with your back supported, both feet flat and legs uncrossed, and rest for at least five minutes.
- Use an upper-arm cuff on bare skin, snug but not tight, with its lower edge about 1 inch above the bend of your elbow.
- Rest your arm on a table so the cuff sits at chest height.
- Stay quiet while the cuff inflates.
- Take at least two readings, 1 or 2 minutes apart, at the same time each day, and write every result in a log.
Bring the log and the monitor to your visit. MedlinePlus suggests asking your provider to compare home and office readings to confirm your device is accurate.
What a Diagnostic Visit Includes
A blood pressure check in National City for a high number should go beyond one squeeze of the cuff. Expect:
- Repeat readings taken after you rest, using the right cuff and position.
- Your history: the NHLBI notes that providers ask about eating patterns, physical activity, sleep, weight, stress and family health history.
- A physical exam focused on the heart, lungs and signs of complications.
- Lab testing: MedlinePlus lists a basic metabolic panel, a urinalysis and cholesterol testing among the tests providers may order.
- A plan: lifestyle steps, whether medicine makes sense, and when to recheck.
The kidney checks matter. The National Institute of Diabetes and Digestive and Kidney Diseases reports that high blood pressure is the second leading cause of kidney failure in the United States, after diabetes. A GFR blood test and a urine albumin test show how well your kidneys are holding up. See our full list of services.
Family History, Salt and Blood Pressure in National City Households
National City brings together Filipino and Spanish-speaking families, Navy households tied to the nearby base, and working families across the South Bay. If a parent or grandparent has high blood pressure, mention it at your visit: the CDC lists family history as a risk factor.
Research also points to a higher burden for Filipino Americans. In a study of more than 1.8 million Northern California adults, Filipino adults had higher hypertension rates than South Asian, Chinese, Hispanic and White adults at every age from their 30s through their 70s, tracking closely with Black adults. A national analysis of death records found that Filipino men had the highest rate of hypertension-related cardiovascular deaths among the Asian American groups studied. Among Hispanic adults nationally, the CDC puts the share with high blood pressure at 44.9%. A group statistic is no one's personal diagnosis, but it is a good reason to check.
Salt hides in soy sauce, fish sauce, cured meats, canned goods and takeout, in kitchens of every background. The CDC notes that Americans average more than 3,300 mg of sodium a day, above the recommended limit of less than 2,300 mg, and that too much sodium can raise blood pressure. Taste before adding sauce, build flavor with garlic, vinegar, citrus and herbs, and save the saltiest dishes for special occasions.
Frequently Asked Questions
Should I go to urgent care or the ER for high blood pressure?
Call 911 right away, without waiting to recheck, if you have sudden chest pain, trouble breathing, numbness or weakness, trouble speaking, a sudden change in vision or a sudden severe headache, whatever your reading. With no symptoms, recheck after five minutes if the top number is 180 or higher or the bottom number is 120 or higher, and call your provider right away if it stays that high. Readings below that level, without symptoms, can be evaluated at urgent care.
Can urgent care treat high blood pressure?
Without emergency symptoms, yes, as a starting point. Urgent care can recheck your pressure, screen for warning signs, order lab tests and discuss treatment and follow-up.
Is one high blood pressure reading a diagnosis?
No. The NHLBI says a diagnosis requires two or more readings at separate appointments. A single high number means recheck and get evaluated.
What are hypertensive crisis symptoms?
The NHLBI lists a sudden severe headache, difficulty breathing, sudden severe chest, back or abdominal pain, numbness or weakness, a sudden change in vision and problems talking. Any of these means call 911 right away, whatever your reading.
