What to do when blood pressure suddenly increases despite normally being normal

Blood pressure that is normally stable but suddenly increases may not require treatment if caused by physiological factors. However, if the increase is due to pathological conditions such as hypertension, cerebral hemorrhage, or hyperthyroidism, appropriate management should be chosen based on the underlying cause.

I. Physiological Factors

If blood pressure temporarily rises due to lack of sleep, excessive emotional excitement, stress, or intense physical activity—leading to overactivation of the sympathetic nervous system—it may result in a transient spike in blood pressure despite normally stable levels. In such cases, it's recommended to adjust your mindset, maintain emotional stability, and establish regular sleep patterns to allow blood pressure to gradually return to normal.

II. Pathological Factors

1. Hypertension: If a person has hypertension and experiences a sudden rise in blood pressure despite previously normal levels, antihypertensive medications such as bisoprolol fumarate tablets or felodipine sustained-release tablets should be taken promptly as directed by a physician to regulate blood pressure.

2. Cerebral Hemorrhage: If cerebral hemorrhage occurs due to head trauma or contusion, increased intracranial pressure or mental stress may lead to a sudden elevation in blood pressure despite prior normal readings. In such cases, medications like irbesartan tablets or telmisartan tablets may be used under medical guidance to alleviate symptoms.

3. Hyperthyroidism (Hyperthyroid): In patients with hyperthyroidism, excessive secretion of thyroid hormones enhances myocardial contractility, leading to increased systolic blood pressure and a sudden rise in blood pressure despite previous normal levels. Once hyperthyroidism is controlled, blood pressure typically stabilizes. Patients may take medications such as methimazole tablets or propylthiouracil tablets as prescribed.

In addition, sudden elevation in blood pressure despite normally stable levels may also be caused by long-term alcohol consumption, pheochromocytoma, or other conditions, and medical treatment under a doctor's guidance is recommended.
