Patients with hypertension are at risk of experiencing easy sleepiness. Hypertension is the most common chronic disease and the most important risk factor for cardiovascular and cerebrovascular diseases. Long-term hypertension can cause ischemia and degeneration of cerebral blood vessels, resulting in cerebral atherosclerosis, which leads to insufficient blood supply to the cerebral blood vessels. Insufficient cerebrovascular blood supply can cause ischemia and hypoxia in the brain, thus making hypertensive patients prone to sleepiness. In addition to sleepiness caused by insufficient cerebrovascular blood supply due to hypertension, it should be noted that some other diseases can also cause sleepiness, such as anemia, malnutrition, anxiety and depression. If the sleepiness does not improve based on active control of blood pressure, it is recommended to consult a doctor in time to improve the relevant examinations and clarify the cause of the disease, so as to avoid delaying the condition and causing adverse consequences.
