Introduction
Low blood pressure usually refers to low diastolic pressure. Persistently or frequently low diastolic pressure can easily lead to reduced heart function. If low diastolic pressure occurs frequently, it may cause insufficient blood supply to the brain, resulting in blurred vision. Long-term low diastolic pressure may lead to multiple discomfort symptoms and negatively affect sleep quality.
Low blood pressure usually refers to low diastolic pressure, which may lead to various health issues such as reduced cardiac function, blurred vision, and decreased sleep quality.
1. Reduced cardiac function
Consistently or chronically low diastolic pressure can easily result in inadequate blood perfusion to the heart, causing ischemia, hypoxia, and subsequent damage to the heart muscle. This leads to diminished cardiac function and symptoms such as palpitations, chest tightness, and discomfort.
2. Blurred vision
Frequent episodes of low diastolic pressure may cause insufficient cerebral blood supply and brain hypoxia, leading to symptoms like dizziness and headache, and potentially resulting in blurred vision.
3. Decreased sleep quality
Occasional episodes of low diastolic pressure generally do not cause significant discomfort or affect sleep quality. However, if it persists over a long period, it may be accompanied by various symptoms such as cold sweats, visual darkening, and generalized weakness in the limbs. These can lead to increased dreaming and frequent awakenings during sleep, ultimately reducing overall sleep quality.
