Does general anesthesia for gastroscopy have any effect on the brain?

General anesthesia used during gastroscopy may have some potential effects on the brain, but it generally does not cause significant side effects. The specific analysis is as follows:

The primary anesthetic agent used in gastroscopy is propofol. After entering the body, this drug typically causes a temporary decrease in intracranial pressure, leading to reduced cerebral blood flow. In some cases, it may even result in brief cerebral hypoxia, causing symptoms such as slowed heart rate, decreased muscle strength, dizziness, and headache after the patient regains consciousness. However, these anesthetic effects are reversible. Given that the body has natural metabolic functions, the drug is gradually eliminated over time, and the aforementioned symptoms usually resolve spontaneously. Therefore, serious long-term impacts on the brain are unlikely, and there is generally no need for excessive concern.

Prior to undergoing general anesthesia for gastroscopy, patients are typically required to undergo relevant evaluations—including electrocardiogram (ECG) and complete blood count (CBC)—under a physician's guidance. These assessments help identify any contraindications for the procedure and aim to minimize risks associated with both surgery and anesthesia as much as possible.
