What causes constant drowsiness and difficulty keeping the eyes open?

Generally, if one constantly feels drowsy and has difficulty keeping the eyes open, it may be caused by lack of sleep, or could also result from conditions such as hypertension or coronary heart disease. Appropriate treatment should be based on the underlying cause.

1. Sleep deprivation: Staying up late frequently at night or experiencing poor sleep quality, frequent dreams, etc., can lead to insufficient sleep, resulting in persistent drowsiness and difficulty keeping the eyes open. Developing healthy lifestyle habits, maintaining a regular sleep schedule, and avoiding late nights can usually relieve these symptoms.

2. Hypertension: In patients with high blood pressure, poor blood pressure control over time can lead to cerebral arteriosclerosis, narrowing or even blockage of cerebral blood vessels, impairing blood supply to brain cells and causing constant drowsiness and difficulty keeping the eyes open. It is recommended to seek timely medical evaluation to prevent hemorrhagic stroke, and to take antihypertensive medications such as nifedipine or amlodipine as prescribed by a doctor.

3. Coronary heart disease: This condition can reduce the heart's ability to pump blood effectively, leading to insufficient cerebral perfusion and symptoms such as persistent drowsiness and difficulty keeping the eyes open. Patients should promptly visit a hospital for electrocardiogram (ECG) testing. After diagnosis, they should take medications such as aspirin or clopidogrel as directed by their physician.
