Is My Blood Pressure Normal? Low Blood Pressure Symptoms

Is my blood pressure normal?

I often feel dizzy, and when I measure my blood pressure at home, my diastolic pressure is only in the 90s.
Is this considered low blood pressure? Should I see a doctor? Does your clinic offer health check-ups? Are they available on Saturdays? How are the costs calculated? Thank you for your help, doctor!

Hello,
1.
A systolic blood pressure greater than 140 mmHg and a diastolic blood pressure greater than 90 mmHg is considered hypertension.
Both high and low blood pressure can cause dizziness, so it is important to measure blood pressure regularly and keep a record.
It is essential to determine whether the systolic pressure is only in the 90s (indicating lower blood pressure) or if the diastolic pressure is greater than 90 (indicating higher blood pressure).

Our hospital is Taoyuan General Hospital, which has a health examination center.
You can call to inquire about the tests available and their costs.
The hospital's phone number is 03-3699721, extension 6026.
Wishing you good health,
Dr.

When it comes to understanding blood pressure and its implications for your health, it's essential to grasp the basics of what constitutes normal blood pressure and the symptoms associated with low blood pressure. Blood pressure is measured in millimeters of mercury (mmHg) and is expressed as two numbers: systolic (the top number) and diastolic (the bottom number). Normal blood pressure is generally considered to be around 120/80 mmHg.
In your case, you mentioned that your diastolic pressure is in the 90s. If your systolic pressure is significantly lower than normal (for example, below 90), this could indicate low blood pressure (hypotension). However, if your systolic pressure is within the normal range but your diastolic pressure is elevated, it may not necessarily mean you have low blood pressure. Instead, it could suggest a condition known as isolated diastolic hypertension, which is less common and often requires further evaluation.

Symptoms of low blood pressure can include dizziness, fainting, fatigue, and in some cases, confusion. If you are frequently experiencing dizziness, it is crucial to take this symptom seriously. Dizziness can be a sign that your brain is not receiving enough blood flow, which can happen if your blood pressure is too low. Other factors, such as dehydration, prolonged bed rest, or certain medications, can also contribute to low blood pressure and its symptoms.

Given your symptoms of frequent dizziness and the readings you provided, it would be advisable to consult a healthcare professional. A doctor can perform a thorough evaluation, which may include a physical examination, blood tests, and possibly an electrocardiogram (ECG) to assess your heart's function. They can also help determine if there are any underlying conditions contributing to your symptoms, such as anemia or autonomic dysfunction.

Regarding your inquiry about health checks at your clinic, many clinics offer routine health screenings, including blood pressure monitoring. It's best to contact your clinic directly to inquire about the availability of health check-ups, especially on weekends, and to understand the associated costs. Health check-ups can provide valuable insights into your overall health and help identify any potential issues early on.

In summary, while your diastolic pressure being in the 90s does not automatically indicate low blood pressure, your symptoms of dizziness warrant further investigation. Consulting with a healthcare provider is the best course of action to ensure that any potential health issues are addressed promptly. Regular monitoring of your blood pressure and maintaining a healthy lifestyle, including proper hydration and nutrition, can also help manage your symptoms.
