Doctor Explains: What Really Happens When You Go Under Anesthesia

Your anesthesiologist probably gave you three sentences: We’ll put you to sleep. You won’t feel anything. You’ll wake up in recovery. If you’re over 60, you deserve far more than that. In this 24-minute deep dive, Dr. Aries Smith walks you through exactly what happens, biologically, neurologically, and chemically, when general anesthesia switches off your consciousness. You’ll also learn what it can mean for the aging brain, including post-operative cognitive dysfunction (POCD) and post-operative delirium. You’ll learn: ✅ What the operating room is really like, and why it’s so cold ✅ How premedication blocks new memories (anterograde amnesia) ✅ What happens in the first 40 seconds after propofol ✅ Why anesthesia is NOT sleep ✅ How anesthesiologists monitor and protect you every minute ✅ The real numbers on anesthesia awareness ✅ How anesthesia may affect the older brain, and the warning signs to watch for ✅ The honest evidence on regional vs. general anesthesia ✅ The 3 questions to write down before any surgery You’re not too old to understand your own body.
