Understand High Blood Pressure Symptoms, Causes, Treatment
Hypertension, or high blood pressure(HTN), occurs when arterial pressure is consistently 130/80 or higher. Often symptomless, it can be managed with regular check-ups and proper medication.
High Blood Pressure Symptoms
Individuals with extremely high blood pressure may experience symptoms such as:
- Headaches: Particularly severe or persistent headaches.
- Dizziness: Feeling lightheaded or unsteady.
- Nosebleeds: Unexplained or frequent nosebleeds.
- Shortness of Breath: Difficulty breathing or feeling short of breath.
- Chest Pain: Pain or pressure in the chest.
- Vision Problems: Blurred vision or seeing spots.
- Fatigue: Unusual tiredness or fatigue.
- Irregular Heartbeat: Palpitations or an irregular heartbeat.

Treatment often involves a combination of lifestyle changes and medication. Here are some common treatments for high blood pressure:
Lifestyle Changes
- Dietary Modifications:
- Reduce Sodium Intake: Aim for less than 2,300 mg per day, or even lower if advised by a doctor.
- DASH Diet: Focus on fruits, vegetables, whole grains, and low-fat dairy products.
- Limit Alcohol: Men should have no more than two drinks per day, and women should limit to one drink per day.
- Exercise:
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking.
- Weight Management:
- Healthy Weight: Losing even a small amount of weight if overweight can help reduce blood pressure.
- Quit Smoking:
- Smoking Cessation: Quitting smoking improves overall heart health and helps lower blood pressure.
- Stress Management:
- Reduce Stress: Techniques such as yoga, meditation, and deep breathing exercises can help manage stress levels.
Medications
Doctors may prescribe medication if lifestyle changes are insufficient to lower blood pressure. The types of medications include:
- Diuretics: Help kidneys remove excess sodium and water from the body.
- Beta-Blockers: Reduce the workload on the heart and open blood vessels.
- ACE Inhibitors: Help relax blood vessels by blocking the formation of a natural chemical that narrows blood vessels.
- Angiotensin II Receptor Blockers (ARBs) Help relax blood vessels by blocking the action of a natural chemical that narrows blood vessels.
- Calcium Channel Blockers: Help relax the muscles of blood vessels.
- Renin Inhibitors: Slow down the production of renin, an enzyme produced by the kidneys that starts a chain of chemical steps that increases blood pressure.
Monitoring and Follow-Up
Regular monitoring and follow-up with a healthcare provider are essential to ensure the effectiveness of the treatment plan. Blood pressure should be regularly checked, and adjustments to the treatment plan should be made as necessary.
Some people may also explore complementary therapies, such as:
- Acupuncture
- Herbal Supplements: Always consult a doctor before using any supplements, as they can interact with medications.
Causes of High Blood Pressure(Hypertension)
Unknown Primary Cause: The leading cause of high blood pressure is often unknown, but several factors contribute.
- Smoking: Damages arteries and temporarily raises blood pressure.
- Overweight: Increases blood volume, putting pressure on arteries.
- Lack of Physical Activity: Leads to weight gain and higher heart rate.
- Excessive Sodium Intake: Raises blood pressure and can harm kidneys. Limit salt intake.
- Alcohol Consumption: Regular drinking raises blood pressure and affects heart rate.
- Stress: Stress Increases blood pressure; manage with meditation or exercise.
- Family History: Genetic predisposition to high blood pressure.
- Chronic Kidney Disease: Damages kidneys, impairing waste removal and increasing pressure.
- Adrenal and Thyroid Disorders: Hormonal imbalances from these conditions raise blood pressure.
- Sleep Apnea: Disturbs normal blood pressure regulation during sleep.
Blood Pressure Range
Blood pressure categories include normal, low, and high, each with specific values and treatments.
| Blood Pressure Category | Systolic/Diastolic Value (mm Hg) | Description |
|---|---|---|
| Low Blood Pressure | 90/60 or less | This situation is considered low blood pressure. |
| Healthy and Ideal | More than 90/60 and less than 120/80 | This condition is considered healthy and ideal. |
| Normal Blood Pressure | 120/80 to 139/89 | This condition is considered normal blood pressure. |
| High Blood Pressure | 140/90 and above | In this condition, see your doctor immediately and start taking medications. |
Diagnosis of High Blood Pressure (Hypertension)
- Blood pressure is commonly measured using a sphygmomanometer, which includes a stethoscope, cuff, dial, pump, and valve. It's recorded as two numbers: systolic and diastolic pressure.
- Systolic blood pressure is the maximum pressure during a heartbeat when the heart sends blood.
- Diastolic blood pressure is the lowest pressure between heartbeats when the heart is filled with blood.
- Blood tests are essential for diagnosing secondary hypertension caused by underlying health issues. These tests aid in identifying the condition's cause and severity.
- Electrolyte levels
- Blood glucose
- Thyroid function tests
- Kidney function tests: blood urea nitrogen (BUN) and creatinine levels
- Urine tests: Urinalysis can detect underlying causes like diabetes, kidney failure, or drug use contributing to high blood pressure.
- Imaging Tests: Imaging tests aid in diagnosing hypertension and related complications by assessing heart and kidney function.
- Electrocardiogram (EKG): An EKG assesses heart rhythm, which can be affected by anomalies or long-term changes due to hypertension.
- Ultrasound: An ultrasound evaluates kidneys and blood vessels, which is helpful if your doctor suspects blood flow issues, such as vessel narrowing.
- CT scan or MRI: If a tumor is suspected as the cause of high blood pressure, imaging tests like CT scans or MRIs may be needed to assess the kidneys or adrenal glands.

Book an AppointmentWhen to see a Doctor?
- High blood pressure often doesn't present symptoms, but sudden severe headaches or nosebleeds should prompt a blood pressure check.
- Severe symptoms like chest pain, shortness of breath, or visual difficulties require urgent medical attention, potentially indicating a hypertensive crisis.
- Medications for hypertension may cause dizziness; if persistent or affecting daily activities, consult a doctor.
Prevention of High Blood Pressure(Hypertension)
- Eat healthy food: To help control your blood pressure, you should restrict the amount of sodium (salt) you eat and increase the amount of potassium in your diet.
- Exercise regularly: You can maintain a healthier weight and lower your blood pressure by exercising.
- Have a healthy weight: Being overweight increases hypertension risk. Maintaining a healthy weight can help control hypertension and reduce other health risks.
- Avoid alcohol Drinking: too much liquor can raise your blood pressure. It also includes extra calories, which can lead to weight gain.
- No smoking: Smoking cigarettes raises blood pressure and increases your risk of heart attack and stroke.
- Cut the caffeine: Caffeine raises blood pressure temporarily, especially for regular consumers of caffeine-containing beverages.
- Lose weight: Being overweight raises blood pressure and increases the risk of conditions like sleep apnea. Losing weight can help control blood pressure and mitigate these risks.
