Introduction
Unstable blood pressure with frequent fluctuations may be caused by measurement errors, emotional changes, intense physical activity, irregular medication use, hyperthyroidism, or other factors. It is important to seek timely medical evaluation at a hospital and follow the doctor's recommendations for improvement through general management, medications, or other treatments. In daily life, adopting a healthy lifestyle—such as maintaining a balanced diet and regular sleep patterns—is beneficial for overall health.
Blood pressure instability with frequent fluctuations—rising and falling—may be caused by measurement errors, emotional changes, intense physical activity, irregular medication use, hyperthyroidism, or other factors. It is important to seek timely medical evaluation and follow a doctor's recommendations for improvement through general management, medications, or other treatments. Specific causes are analyzed as follows:
1. Measurement error: If proper blood pressure measurement techniques are not followed, inaccurate readings may occur, leading to apparent fluctuations in blood pressure. Before measuring blood pressure, one should remain in a calm state and avoid strenuous exercise.
2. Emotional changes: Emotional states such as anxiety, tension, or excitement can easily cause blood pressure fluctuations, resulting in the aforementioned symptoms. It is recommended to manage emotions using appropriate methods such as deep breathing or listening to music.
3. Intense physical activity: During vigorous exercise, blood circulation accelerates and the sympathetic nervous system is stimulated, causing blood pressure to rise. After exercise stops, blood pressure gradually returns to normal. This is a normal physiological response and typically does not require specific treatment.
4. Irregular medication use: For individuals with hypertension, inconsistent use of prescribed medications may lead to blood pressure fluctuations. Such patients should strictly adhere to medical instructions when taking antihypertensive drugs to maintain stable blood pressure control.
5. Hyperthyroidism: This condition is often related to factors such as medications or infections and involves excessive secretion of thyroid hormones. It may cause the aforementioned symptoms, along with palpitations, increased appetite, and other signs. Under a doctor’s guidance, medications such as propylthiouracil tablets, carbimazole tablets, or metoprolol tartrate tablets may be used to alleviate symptoms.
Maintaining a healthy lifestyle—including balanced nutrition and regular sleep patterns—is beneficial for overall health.
