Dr. Wang Xin
Low blood pressure, medically referred to as hypotension, may pose certain health risks when blood pressure remains below the normal range for a prolonged period. The main manifestations include the following aspects:
1. Insufficient cerebral blood supply: Severely low blood pressure may lead to inadequate blood flow to the brain, causing dizziness, headaches, memory decline, and in severe cases, fainting.
2. Systemic circulation problems: All tissues and organs in the body require blood to supply nutrients and oxygen. Low blood pressure can impair this supply, leading to systemic metabolic disturbances and affecting the normal function of multiple organ systems.
3. Cardiac damage: Long-term low blood pressure may cause left ventricular hypertrophy (thickening of the heart muscle), which can progress to heart failure, presenting symptoms such as shortness of breath and chest tightness.
4. Retinal damage: Poorly controlled low blood pressure may lead to retinal damage, and in severe cases, complications such as retinal hemorrhage and optic disc edema may occur.
5. Vascular damage: Chronic low blood pressure may damage cerebral blood vessels, increasing the risk of acute ischemic stroke and acute cerebral hemorrhage.
For persistent low blood pressure, prompt medical attention is recommended.
