What Causes Frequent Dizziness Due to Low Blood Pressure?

Today, many people suffer from hypertension; in fact, a considerable number also experience hypotension. If hypotension is mild, it may cause no symptoms at all—but without proper evaluation, the condition can worsen and progress to severe hypotension. Therefore, understanding the underlying causes of hypotension remains essential for targeted treatment. So, what causes recurrent dizziness associated with low blood pressure?

What Causes Recurrent Dizziness in Hypotension?

If a patient currently experiences dizziness due to hypotension, combined antihypotensive therapy is recommended—for example, drinking Shengmai beverage or receiving intravenous Shengmai injection (a traditional Chinese medicine formulation) to help raise blood pressure and alleviate dizziness. However, if the hypotension is genetically determined, the dizziness—regardless of whether it stems directly from low blood pressure—should be evaluated for alternative causes, such as insufficient cerebral arterial perfusion or inadequate rest.

Patients with hypotension should slightly elevate their head while sleeping using an appropriate pillow, which helps relieve symptoms. Upon waking in the morning—or after weight loss or defecation—they should rise slowly rather than abruptly. Bath water temperature should be moderate—not excessively hot or cold—to avoid triggering blood pressure fluctuations. Additionally, prolonged exposure to hot, stuffy, or oxygen-deficient environments must be avoided. Oral intake of lightly salted water may also be beneficial, as it helps expand circulating blood volume and supports blood pressure elevation.

In such cases, the first priority is emotional stabilization and adequate rest, along with ensuring high-quality sleep. A light, balanced diet is generally advised, emphasizing fresh fruits and vegetables. We hope this information proves helpful to you.
