Hypertension: Causes, Risks, and Management for Seniors

Hypertension issues?

Hello Doctor: My mother is over fifty years old and often experiences rapid heartbeat and dizziness.
We took her to a clinic for examination, and upon measuring her blood pressure, we discovered it was alarmingly high, with a systolic pressure of 180 mmHg and a diastolic pressure of 100 mmHg.
The doctor diagnosed her with hypertension.
Previously, my friend's mother also went for a check-up due to high blood pressure, and the doctor told him it was caused by menopause, which led to hypertension.
Therefore, I asked the doctor if my mother's condition was related to menopause since she is over fifty, but he said it was hereditary rather than related to menopause.
My grandmother also had a stroke due to high blood pressure, and the doctor informed us that her stroke was caused by left ventricular hypertrophy, which led to hypertension.
The doctor mentioned that eighty percent of hypertension cases are related to the heart.
I am a bit confused and would like to ask the doctor, what are the causes of hypertension? Is it really unrelated to menopause? Do people with hypertension need to take medication long-term to manage it? Thank you...

Dr. Lin Changqi reply Cardiology

There are many causes of hypertension, with approximately 90% classified as essential hypertension (of unknown origin) and the remaining 10% as secondary hypertension (such as renal, endocrine, and vascular hypertension).
Due to the various causes of hypertension, initial cases require certain examinations for differential diagnosis.
Menopause, due to changes in physical condition, may affect hypertension, but other factors must be ruled out before making a determination.
Pharmacological treatment for hypertension should first focus on modifying diet and lifestyle.
If blood pressure remains elevated, long-term medication management may still be necessary, but this should be determined based on the individual case.

More Info

Hypertension, or high blood pressure, is a common condition that affects many individuals, particularly seniors. Understanding its causes, risks, and management strategies is crucial for maintaining health and preventing complications.

Causes of Hypertension
Hypertension can be classified into two main categories: primary (essential) hypertension and secondary hypertension.
1. Primary Hypertension: This is the most common form, accounting for about 90-95% of cases. The exact cause is often unknown, but several factors contribute to its development:
- Genetics: A family history of hypertension increases the likelihood of developing the condition.

- Age: Blood pressure tends to rise with age due to changes in blood vessel elasticity.

- Lifestyle Factors: Poor diet (high in salt, saturated fats, and sugar), lack of physical activity, obesity, excessive alcohol consumption, and smoking can all contribute to hypertension.

2. Secondary Hypertension: This type is caused by an underlying condition, such as:
- Kidney Disease: Conditions affecting the kidneys can lead to fluid retention and increased blood pressure.

- Hormonal Disorders: Disorders such as hyperthyroidism or adrenal gland tumors can cause secondary hypertension.

- Medications: Certain medications, including NSAIDs, decongestants, and some prescription drugs, can raise blood pressure.

In your mother's case, her age and symptoms, such as rapid heartbeat and dizziness, may indicate hypertension, which can be exacerbated by lifestyle factors and possibly genetic predisposition. While menopause can influence blood pressure due to hormonal changes, it is not the sole cause of hypertension.

Risks Associated with Hypertension
Uncontrolled hypertension poses significant health risks, particularly for seniors. These include:
- Cardiovascular Disease: High blood pressure can lead to heart disease, heart failure, and stroke.

- Kidney Damage: Hypertension can damage blood vessels in the kidneys, leading to chronic kidney disease.

- Vision Loss: High blood pressure can cause damage to the retina, leading to vision problems.

- Cognitive Decline: There is evidence linking hypertension to cognitive impairment and dementia.

Given your family history of hypertension and stroke, it is particularly important for your mother to manage her blood pressure effectively.

Management of Hypertension
Managing hypertension typically involves a combination of lifestyle changes and medication. Here are some strategies:
1. Lifestyle Modifications:
- Diet: Encourage a heart-healthy diet rich in fruits, vegetables, whole grains, and low-fat dairy products. The DASH (Dietary Approaches to Stop Hypertension) diet is often recommended.

- Physical Activity: Regular exercise can help lower blood pressure. Aim for at least 150 minutes of moderate aerobic activity each week.

- Weight Management: Maintaining a healthy weight can significantly impact blood pressure levels.

- Limit Alcohol and Quit Smoking: Reducing alcohol intake and quitting smoking can improve overall cardiovascular health.

2. Medication: If lifestyle changes are insufficient to control blood pressure, medication may be necessary. Common classes of antihypertensive medications include:
- Diuretics: Help reduce blood volume.

- ACE Inhibitors: Relax blood vessels by inhibiting the formation of a hormone that narrows blood vessels.

- Beta-Blockers: Reduce heart rate and the heart's workload.

- Calcium Channel Blockers: Relax blood vessels and decrease heart rate.

Your mother's healthcare provider will determine the most appropriate medication based on her specific health needs and any other underlying conditions.

Conclusion
In summary, hypertension is a multifactorial condition influenced by genetics, lifestyle, and age. While menopause can play a role, it is not the sole factor. Given your mother's elevated blood pressure and family history, it is essential to pursue both lifestyle modifications and potential medication management to control her blood pressure effectively. Regular follow-ups with her healthcare provider will help monitor her condition and adjust treatment as necessary.
