145 90 Blood Pressure While On Medication
Blood pressure is the force of the blood against the walls of the arteries as it goes around a person's body. Sometimes, it can become too high, which can be dangerous.
According to the Centers for Disease Control and Prevention (CDC), roughly
In this article, we explore the myths surrounding high blood pressure symptoms. We also discuss when to see a doctor and how to manage hypertension.
Most of the time, high blood pressure has no symptoms. It is known as
Symptoms people may think are due to high blood pressure include:
- headaches
- difficulty sleeping
- nosebleeds
- sweating
- facial flushing
- nervousness
- blood spots in the eyes
- dizziness
However, these symptoms may not be due to high blood pressure, and anyone experiencing them should speak to a doctor as they may also be signs of other health conditions or side effects of medications.
People cannot rely on only physical symptoms to alert them of high blood pressure. To diagnose or monitor hypertension, a person should measure their blood pressure regularly.
A person can measure their blood pressure at home.
Blood pressure readings are in millimeters of mercury (mm Hg). The top number (systolic) indicates the pressure in the arteries as the heart beats. The lower number (diastolic) indicates the pressure as the heart rests between beats.
As long as a person measures their blood pressure correctly, the results are just as reliable as a doctor's measurement.
The following table, from the
| Normal blood pressure | Elevated blood pressure | Stage 1 hypertension | Stage 2 hypertension | Hypertensive crisis | |
| Systolic blood pressure | less than 120 mm Hg | 120–129 mm Hg | 130–139 mm Hg | 140 mm Hg or higher | 180 mm Hg or higher |
| Diastolic blood pressure | less than 80 mm Hg | less than 80 mm Hg | 80–89 mm Hg | 90 mm Hg or higher | 120 mm Hg or higher |

Although high blood pressure does not usually cause symptoms, anyone experiencing a sudden, severe headache or nosebleed should check their blood pressure.
If their blood pressure is above 180/120 mm Hg, they should stay rested for 5 minutes and recheck their blood pressure. If the blood pressure is still higher than 180/120 mm Hg, they need to seek medical help at their doctor's office.
If a person is experiencing severe symptoms, such as chest pain, shortness of breath, or visual difficulty, they need to call 911 for emergency medical treatment as they may be experiencing a hypertensive crisis.
Medications to reduce blood pressure can cause side effects such as dizziness. If this side effect does not go away or affects a person's daily activities, they should speak with their family doctor.
Researchers have shown a clear relationship between higher systolic and diastolic blood pressure and increased risk of cardiovascular disease.
In an analysis of 61 studies, researchers found that a 20 mm Hg higher systolic and a 10 mm Hg higher diastolic blood pressure were each associated with a doubling of the risk of:
- stroke
- heart disease
- other vascular diseases
Another study including
- increased risk of cardiovascular disease incidence
- angina
- heart attack
- heart failure
- stroke
- peripheral arterial disease
- abdominal aortic aneurysm
Genetics
According to the
One review states that a person's chance of inheriting high blood pressure is roughly 30–50%. The review also notes that although researchers have isolated genes that control blood pressure, these gene variants accounted for only 2–3% of genetic variations in blood pressure.
Lifestyle factors
The following environmental factors may influence a person's blood pressure:
- Excessive salt intake: The National Heart, Lung, and Blood Institute (NHLBI) recommend that people consume no more than
2.4 grams (g) of sodium per day, which is about 1 teaspoon (tsp) of table salt per day. - Low potassium intake: Potassium helps the body remove sodium. The AHA recommend a person consumes
4,700 milligrams (mg) per day. - Weight: According to a comprehensive report by the American College of Cardiology and the AHA Task Force, people can expect to lower their blood pressure by around 1 mm Hg per 1 kilogram (2.2 pounds) of weight loss.
- Exercise: A 2015 study indicated that aerobic exercise could reduce blood pressure by
5–7 mm Hg .
Since there is a strong connection between environmental factors and blood pressure, healthcare professionals have been promoting hypertension prevention.
The
- eating a healthful diet low in salt
- limiting alcohol intake
- enjoying regular physical activity
- managing stress
- maintaining a healthy weight
- quitting tobacco smoking
A
- fruits
- vegetables
- whole grains
- low fat dairy products
- skinless poultry and fish
- nuts and legumes
- non-tropical vegetable oils
People who follow a healthful diet to prevent hypertension and cardiovascular disease should also avoid or limit:
- saturated and trans fats
- sodium
- red meat
- sweets and sugar-sweetened beverages
People who eat well, stop smoking, lower their stress, and exercise regularly may see benefits in their general health.
The DASH diet (Dietary Approaches to Stop Hypertension) may be beneficial in helping to prevent or treat high blood pressure.

Doctors and health professionals often refer to high blood pressure as a silent killer, and it is a risk factor associated with cardiovascular disease.
People who have high blood pressure may not experience any physical symptoms and may not be aware that their blood pressure is high.
During a hypertensive crisis, people with a blood pressure above 180/120 mm Hg may experience symptoms such as chest pain, shortness of breath, blurry vision, headache, or nosebleed.
People experiencing a hypertensive crisis require emergency medical attention.
The most reliable way to detect high blood pressure is by regularly checking blood pressure measurements.
