Patient's question:
After waking up, I went to have breakfast and came to the library to read, but I couldn't focus on the books. I kept feeling dizzy and had a headache, and even blinking felt exhausting. I don't know what the reason is.Doctor's answer:
Dizziness and a stuffy head may be caused by the following reasons:1. Hypertension: After developing hypertension, excessively high blood pressure disrupts the function of blood vessel dilation and contraction, leading to headaches, dizziness, and a stuffy head.
2. Sleep disorders: When nighttime sleep duration is insufficient or sleep quality is poor, deep sleep time decreases, and brain tissue does not get adequate rest, resulting in daytime dizziness, a heavy head, and a stuffy head.
3. Arteriosclerosis of cerebral arteries: In elderly patients, long-term arteriosclerosis increases the resistance index of blood vessels, slows cerebral blood flow velocity, and causes brain tissue ischemia and hypoxia, leading to persistent dizziness and a stuffy head during the day.
4. Dizziness and a stuffy head can also be caused by eye diseases.
