What causes unstable low blood pressure?

Blood pressure instability may be caused by lifestyle factors, psychological factors, medication issues, or other reasons, and adjustments should be made according to the specific situation.

1. Lifestyle Factors

Irregular lifestyle and daily routines—such as drinking alcohol, excessive physical activity, or staying up late—can all lead to blood pressure fluctuations. Avoid these activities before measuring blood pressure; instead, rest for about 10 minutes prior to measurement to obtain an accurate reading.

2. Psychological Factors

If a patient is emotionally agitated, their blood pressure may rise temporarily. Once emotions stabilize, blood pressure will gradually return to normal. It's important to maintain a calm mood, avoid excitement, and refrain from anger in daily life.

3. Medication Factors

For individuals with hypertension, daily intake of antihypertensive medications is essential. Missing or forgetting doses can cause blood pressure to fluctuate. Be sure to take prescribed medications at consistent times every day.

In addition, unstable diastolic blood pressure may also result from atherosclerosis. In such cases, it's recommended to visit a hospital for evaluation to determine the underlying cause. Under medical supervision, treatments may include medications such as aspirin tablets or rosuvastatin tablets.
