What causes high diastolic blood pressure, and how can it be addressed?

Generally, low pressure refers to diastolic blood pressure. Elevated diastolic blood pressure may be caused by unhealthy lifestyle habits, obesity, hyperthyroidism, primary aldosteronism, chronic glomerulonephritis, and other factors. Improvement can be achieved through general treatment and medication. Prompt medical consultation and adherence to medical advice for treatment are necessary. Specific details are as follows:

1. Unhealthy lifestyle: High-pressure and high-demand work conditions, combined with lack of exercise, irregular eating habits, and a high-salt, high-fat diet, can increase peripheral vascular resistance and heart rate, thereby raising diastolic blood pressure and possibly causing dizziness. A low-salt, low-fat diet should be maintained, with increased consumption of fresh fruits and vegetables, while intake of high-salt and high-fat foods should be limited. Maintain a regular routine and avoid excessive fatigue and mental stress.

2. Obesity: Obesity increases body mass, requiring the heart to pump more blood to maintain adequate circulation, thus increasing heart rate and myocardial contractility, which raises diastolic blood pressure and is accompanied by weight gain. Weight reduction should be achieved through proper diet and increased physical activity, while avoiding excessive alcohol consumption and smoking.

3. Hyperthyroidism: Patients with hyperthyroidism experience elevated metabolic rates due to excessive secretion of thyroid hormones, which enhances cardiac contractility and reduces vascular relaxation capacity, thereby increasing diastolic blood pressure and often accompanied by palpitations. Under a doctor's guidance, medications such as methylthiouracil tablets, enteric-coated propylthiouracil capsules, and propranolol hydrochloride tablets can be used to inhibit the synthesis and release of thyroid hormones.

4. Primary aldosteronism: Patients with primary aldosteronism secrete excessive aldosterone from the adrenal cortex, leading to sodium retention and increased blood volume, which elevates diastolic blood pressure and is often accompanied by hypokalemia. Under medical guidance, medications such as nifedipine tablets, amlodipine besylate tablets, and nicardipine hydrochloride tablets can be used to inhibit aldosterone secretion.

5. Chronic glomerulonephritis: Patients with chronic glomerulonephritis have impaired kidney function, making it difficult to regulate water and electrolyte balance, leading to fluid and sodium retention and increased blood volume, which elevates diastolic blood pressure and is often accompanied by edema. Follow medical advice to use anti-inflammatory medications such as prednisone acetate tablets, methylprednisolone tablets, and hydrocortisone acetate tablets.

Appropriate treatment plans should be selected based on individual conditions under a doctor's guidance, with regular blood pressure monitoring to ensure it remains within a healthy range.
