High blood pressure (hypertension; ICD-10 I10) is a chronic condition where the force of blood against artery walls stays elevated over time. Per the 2017 ACC/AHA guideline, normal is below 120/80 mmHg, Stage 1 is 130-139/80-89 mmHg, and Stage 2 is 140/90 mmHg or higher. About 1 in 3 U.S. adults — roughly 47% — has hypertension (CDC 2024), and only about 1 in 4 of those have it controlled. At Viva Medical Center in Doral, FL, we evaluate blood pressure with confirmed in-office plus home readings, screen for secondary causes when the pattern is unusual, and build a treatment plan that fits your goals, your work schedule, and what your insurance covers.
What hypertension is and how it is diagnosed
Hypertension is diagnosed from multiple readings, not a single elevated value at one visit. The ACC/AHA 2017 guideline asks for two or more readings on two or more separate occasions, and the U.S. Preventive Services Task Force recommends confirming high office readings with out-of-office monitoring (home or 24-hour ambulatory) before starting medication. We follow that two-step approach. At your visit we use a validated automated cuff with correct sizing, give you a quiet 5 minutes before the reading, and take an average — not a single number. If readings are inconsistent, we send you home with a home BP log or order ambulatory monitoring before committing to a long-term medication plan.
Symptoms — usually silent, which is why screening matters
- Most cases have no symptoms — high blood pressure is called the silent killer for this reason
- Morning headaches that resolve once BP is controlled (only in markedly elevated cases)
- Vision changes, nosebleeds, or pounding in the chest with severe hypertension (>180/120)
- Reduced exercise tolerance and fatigue in long-standing untreated cases
- Symptoms of complications — chest pressure, shortness of breath, leg swelling — when end-organ damage develops
How we treat hypertension at Viva Medical Center in Doral
Treatment is layered. We start with the lifestyle changes that have the strongest evidence — DASH-pattern eating, sodium reduction, weight management when relevant, regular activity, sleep, and limiting alcohol. When medication is needed, your physician will recommend a class based on your age, kidney function, other conditions, and what you tolerate. Common first-line classes per the 2017 ACC/AHA guideline include ACE inhibitors, angiotensin receptor blockers (ARBs), calcium channel blockers, and thiazide diuretics, with beta-blockers reserved for specific indications such as coronary disease, arrhythmia, or post-heart-attack care. We do not name specific brands here — choice is individual and your physician will review options, side effects, and cost during your visit.
- Confirmed-diagnosis workup including kidney function, electrolytes, fasting lipids, glucose, and an EKG
- Lifestyle plan — DASH-pattern eating, sodium reduction toward the AHA 1,500-2,300 mg/day target, structured activity
- Medication from FDA-approved antihypertensive drug classes when lifestyle alone is not enough
- Home blood pressure monitoring with teach-back so your readings actually count
- Periodic lab and kidney monitoring on schedule for whichever class you are on
- Coordination with cardiology for resistant hypertension, secondary causes, or evidence of organ damage
DASH diet, sodium, and the lifestyle changes that move the numbers
Lifestyle change is not a substitute for medication when blood pressure is high — but it routinely lowers systolic BP by 5-11 mmHg in clinical trials and can let many patients use a lower medication dose. The DASH eating pattern emphasizes vegetables, fruit, whole grains, legumes, nuts, low-fat dairy, and limited red and processed meat. Sodium reduction is the lever with the biggest blood-pressure effect for most patients; the AHA recommends an ideal limit of 1,500 mg/day for most adults with hypertension, with 2,300 mg/day as a reasonable interim target. We give you a plain-language plan and a Cuban/Latin-American food adaptation list so this is realistic in a Doral or Miami household, not an abstract diet sheet.
Home blood pressure monitoring — how to do it correctly
- Use a validated upper-arm cuff (wrist cuffs read inaccurately for most people)
- Sit quietly for 5 minutes before taking the reading, feet flat, back supported, arm at heart level
- Take two readings 1 minute apart, twice a day, for at least 5 days, and bring the log to your visit
- Avoid caffeine, exercise, or smoking for 30 minutes before measuring
- If a reading is >180/120 with symptoms — chest pain, shortness of breath, vision change, weakness — call 911
Complications if hypertension is left untreated
Hypertension is one of the leading preventable causes of heart attack, stroke, kidney failure, and vascular dementia. Per CDC and AHA data, controlling blood pressure to target reduces stroke risk by roughly 35-40% and heart-attack risk by 20-25%. The complications that build over years — left ventricular hypertrophy, chronic kidney disease, peripheral artery disease, retinopathy — are the reason we treat numbers that feel completely fine. Early treatment changes the long-term trajectory; we screen for early organ damage with lab work and EKG so the plan matches your actual risk, not just a generic protocol.
Secondary and resistant hypertension — when the workup matters
Most hypertension is essential — there is no single cause and treatment is empiric. But about 5-10% of adults with hypertension have a secondary cause that needs identification. Per ACC/AHA 2017 guidance, we evaluate for secondary hypertension when blood pressure is severe, sudden in onset, resistant to three medications including a diuretic, or appears in patients under 30. Common causes include obstructive sleep apnea, primary aldosteronism, renal artery disease, thyroid disorders, and certain medications including some non-prescription supplements. We screen with a structured workup — basic labs, urine studies, a sleep questionnaire — and refer to nephrology, endocrinology, or sleep medicine when the picture warrants it.

Frequently Asked Questions
What is hypertension and how is it diagnosed?
Hypertension (ICD-10 I10) is consistently elevated blood pressure. Per the 2017 ACC/AHA guideline, normal is <120/80, Stage 1 is 130-139/80-89, and Stage 2 is 140/90 or higher. Diagnosis requires multiple readings on separate days, ideally confirmed with home or 24-hour ambulatory monitoring before starting medication, as recommended by the U.S. Preventive Services Task Force.
Does high blood pressure cause symptoms?
Usually not. Most people with hypertension feel completely fine until a complication — heart attack, stroke, kidney damage — develops, which is why CDC calls it the silent killer. Headaches, vision changes, or nosebleeds typically appear only with severe elevations above 180/120. The only reliable way to know your numbers is to measure them.
How is hypertension treated at Viva Medical Center?
Treatment combines lifestyle change with medication when needed. Lifestyle covers DASH-pattern eating, sodium reduction toward 1,500-2,300 mg/day, weight and activity goals, and limiting alcohol. Medication classes we use follow the 2017 ACC/AHA guideline — ACE inhibitors, ARBs, calcium channel blockers, and thiazide diuretics as first-line, with beta-blockers for specific indications. Your physician will recommend a class based on your full profile.
How should I take my blood pressure at home?
Use a validated upper-arm cuff, not a wrist cuff. Sit quietly for 5 minutes first, feet flat, back supported, arm at heart level. Take two readings a minute apart, twice a day, for at least 5 days, and bring the log to your visit. Avoid caffeine, exercise, or smoking for 30 minutes before measuring. We coach this teach-back style at every visit.
When should I call you same-day vs. go to the ER?
Call us same-day for a home BP consistently above 140/90, a medication side effect, missed doses, or a new diagnosis you want explained. Go to the ER or call 911 for BP above 180/120 with chest pressure, shortness of breath, slurred speech, one-sided weakness, sudden vision change, severe back pain, or any pregnancy-related BP above 140/90.
Does insurance cover hypertension visits?
Yes. Viva Medical Center is in-network with Oscar Health, Aetna, Cigna, Humana, Medicare Advantage, Ambetter, and UnitedHealthcare. Office visits, lab work, EKG, and follow-up are covered under your primary care benefit. The front desk verifies your specific plan before the first visit and gives you a written estimate for anything not fully covered.
Do I need to lose weight to lower my blood pressure?
Not necessarily — but if you carry extra weight, losing even 5-10 pounds typically lowers systolic blood pressure by several points and can let you use a lower medication dose. The DASH-pattern diet, sodium reduction, and consistent activity move the numbers independently of weight. Your physician will set a realistic plan that fits your starting point.
Is bilingual care available?
Yes. Intake, the visit itself, telehealth follow-ups, lab review, and discharge instructions are all available in English and Spanish. Our blood pressure logs, DASH food lists, and home-monitoring teach-back materials are bilingual so the plan works in a real Doral or Miami household.
Will I be on blood pressure medication for life?
Not always. Some patients with newer Stage 1 hypertension control their numbers with lifestyle alone or come off medication after sustained weight loss and dietary change. Others with Stage 2 hypertension, kidney disease, diabetes, or a strong family pattern will benefit from long-term medication. Your physician sets realistic expectations at the first visit and revisits the plan at every follow-up.
Can I be seen by telehealth?
The first visit is typically in-person so we can confirm an accurate baseline reading, perform an exam, and order labs. Follow-ups, medication adjustments, and lab review work well by telehealth for most patients once your home BP log is established. Telehealth follow-ups are bilingual and HIPAA-compliant.
