What is high blood pressure?

Blood pressure is the force of blood against the walls of your arteries. It is written as two numbers: the top (systolic) and the bottom (diastolic), for example 120/80 mm Hg.

Most people with high blood pressure feel nothing. That is why many don’t know they have it, and over the years it can damage the heart, kidneys, eyes and brain without warning. The only way to know is to measure it. According to MedlinePlus, repeated nosebleeds can be a sign of another condition, such as high blood pressure: see nosebleed. These categories apply to adults who are not taking blood pressure medicine and are not ill:

  • Normal: under 120 and under 80.
  • Elevated: 120 to 129 and under 80.
  • Stage 1 high blood pressure: 130 to 139, or 80 to 89.
  • Stage 2 high blood pressure: 140 or higher, or 90 or higher.
  • Hypertensive crisis: higher than 180, or higher than 120. Get medical care right away.

How we treat high blood pressure by video

You see Dr. Diana Nieves Castro, a Puerto Rico–licensed general practice physician with several years of emergency-department experience, in English or Spanish. We evaluate, diagnose and treat: the doctor reviews your home readings, history, medicines and side effects, and helps you with lifestyle changes.

If blood or urine tests are needed, for example to check your kidneys, blood sugar or cholesterol, we give you a lab order for a lab near you and go over the results with you. If appropriate, the doctor prescribes and we send your prescription to your pharmacy. For long-term follow-up, see chronic care. Your online primary care doctor also checks your blood pressure along with the rest of your health.

You need to be physically in Puerto Rico during the visit; if you have just moved here or are visiting, we see you too.

What a blood pressure visit costs

New or uncontrolled high blood pressure is handled in a US$79 doctor visit. If you already take a blood pressure medicine and only need a refill, it is a US$49 follow-up visit: see prescription refills. If a follow-up turns out to need a full visit, the doctor explains why and, with your consent, you pay the difference.

The same price for every age, with no membership. You pay by card when you request the visit, and you get a full refund if the visit can’t take place. A doctor’s note is included. We do not bill insurance; the lab and the pharmacy charge separately. See all prices. The service is run by The Health Initiative, a nonprofit.

Symptoms of very high blood pressure

High blood pressure usually causes no symptoms. But extremely high blood pressure (malignant hypertension) is an emergency and can cause:

  • Severe headache
  • Nausea and vomiting
  • Confusion
  • Vision changes
  • Nosebleeds

Treatment, and when lab tests are ordered

Treatment usually starts with lifestyle changes: a heart-healthy diet with less salt (under 1,500 mg of sodium a day), at least 150 minutes of exercise a week, a healthy weight, limiting alcohol and quitting smoking.

If that isn’t enough, or if you have stage 2 blood pressure, diabetes or heart disease, medicines are added. The most used types are diuretics, ACE inhibitors, angiotensin II receptor blockers (ARBs) and calcium channel blockers. Many people need more than one. Never change your dose or stop a medicine on your own; if you have dizziness, cough or tiredness, tell the doctor: there is almost always another option.

The doctor gives you a lab order when you start or change a medicine, to check your kidneys and electrolytes, and to look for other conditions that raise your risk, such as diabetes and high cholesterol.

How to measure your blood pressure at home

Home readings can be a better measure of your real blood pressure than office readings. Use a digital upper-arm monitor with a cuff that fits you and follow these CDC steps:

  • Don’t eat or drink anything for 30 minutes before.
  • Empty your bladder.
  • Sit with your back supported for at least 5 minutes first.
  • Keep both feet flat on the floor, legs uncrossed.
  • Rest your arm on a table at chest height.
  • Put the cuff on bare skin, not over clothing.
  • Don’t talk during the reading.
  • Take at least two readings 1 or 2 minutes apart, at the same time every day, and write them down.

According to the CDC, Puerto Rico had the highest rate of diagnosed diabetes among adults of any U.S. state or territory in 2021: 14.4%, and diabetes raises the risk of high blood pressure. During hurricane season, plan ahead so you don’t run out of your pills: read medications and hurricanes.

High blood pressure in children and teens

In children and teens, blood pressure is not compared with adult numbers but with norms for age, height and sex. The doctor evaluates your child by video with you on camera, reviews readings taken with a correctly sized cuff and, if needed, gives you a lab order for a lab near you.

We see children of all ages. Patients under 21 need a parent or legal guardian on camera with ID.

When to go to the ER

For your safety, call 911 or go to the emergency room if your blood pressure is above 180/120 with symptoms, or if you have any of these signs. See when to go to the ER.

  • Chest pain or pressure
  • Shortness of breath
  • Weakness, numbness or drooping on one side of the body

How we care for you

  • If appropriate, the doctor prescribes and we send your prescription to your pharmacy. We do not prescribe controlled substances.

Frequently asked questions

What are the symptoms of high blood pressure?

Usually none, which is why it should be checked regularly. When blood pressure rises to extreme levels it can cause a severe headache, nausea, confusion, vision changes or nosebleeds, and that is an emergency.

What blood pressure is dangerous?

Above 180/120 is a hypertensive crisis and needs medical care right away. If you also have chest pain, shortness of breath, weakness or trouble speaking, call 911.

Can I get my blood pressure medicine refilled by video in Puerto Rico?

Yes, if the doctor considers it appropriate after reviewing your readings and history. It is a US$49 follow-up visit. If tests are needed, we give you an order for a lab near you. You must be physically in Puerto Rico during the visit.

What should I bring to the visit?

Your home blood pressure readings from the last few days, a list or the boxes of your medicines, and any recent lab results. The doctor reviews them with you by video.
