Blood pressure issues?


Hello, doctor.
I recently started measuring my blood pressure regularly and found that my readings are mostly elevated, with systolic pressure around 140 and heart rate around 85.
My systolic pressure sometimes drops to 120 but can also go as high as 155.
I am 20 years old, usually sleep from 1 to 3 AM, and I have a smoking habit.
My father has hypertension.
My height and weight are 180 cm and 70 kg.
I would like to know if my blood pressure is normal or if I need to seek medical attention.

More Info


At 20 years old, monitoring your blood pressure is a wise decision, especially given your family history of hypertension. Your reported blood pressure readings, with systolic values mostly around 140 mmHg and occasional peaks at 155 mmHg, indicate that you may be experiencing elevated blood pressure. According to the American Heart Association, normal blood pressure is typically defined as less than 120/80 mmHg, while elevated blood pressure is categorized as systolic readings between 120-129 mmHg and diastolic readings less than 80 mmHg. Hypertension is diagnosed when systolic pressure is 130 mmHg or higher or diastolic pressure is 80 mmHg or higher.

Given your readings, it would be prudent to seek medical advice. Here are several factors to consider:
1. Family History: Since your father has high blood pressure, you may be genetically predisposed to developing hypertension. Family history is a significant risk factor for cardiovascular diseases, including hypertension.

2. Lifestyle Factors: Your smoking habit and irregular sleep schedule (going to bed between 1-3 AM) can contribute to elevated blood pressure. Smoking is known to damage blood vessels and increase heart rate, leading to higher blood pressure. Additionally, poor sleep patterns can affect your body's ability to regulate blood pressure effectively.

3. Weight and Height: Your height of 180 cm and weight of 70 kg give you a Body Mass Index (BMI) of approximately 21.6, which is within the normal range. Maintaining a healthy weight is beneficial for blood pressure control.

4. Heart Rate: A resting heart rate of 85 beats per minute is on the higher side of the normal range (60-100 bpm). Elevated heart rates can be associated with stress, anxiety, or other underlying health issues.

5. Monitoring: It’s essential to continue monitoring your blood pressure regularly. Consider measuring it at different times of the day and under various conditions (e.g., after resting, after exercise, etc.) to get a comprehensive view of your blood pressure patterns.

6. Consultation: Given your elevated readings and risk factors, it would be advisable to consult a healthcare professional. They can perform a thorough evaluation, including a physical examination and possibly additional tests, to determine if you have hypertension or if your readings are influenced by other factors such as anxiety or lifestyle habits.

7. Lifestyle Modifications: If you are diagnosed with elevated blood pressure or hypertension, lifestyle changes can be very effective. These include:
- Quitting smoking: This will significantly improve your cardiovascular health.

- Improving sleep hygiene: Aim for 7-9 hours of quality sleep each night.

- Regular physical activity: Aim for at least 150 minutes of moderate aerobic exercise each week.

- Healthy diet: Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while reducing sodium intake.

- Stress management: Techniques such as mindfulness, meditation, or yoga can help lower stress levels.

In summary, while your blood pressure readings suggest that you may be at risk for hypertension, it is crucial to consult a healthcare provider for a comprehensive assessment. They can guide you on the best course of action, which may include lifestyle modifications and, if necessary, medication. Taking proactive steps now can help you maintain healthy blood pressure levels and reduce your risk of cardiovascular disease in the future.
