Anesthesia: What to Expect, Risks, and Recovery

Millions of procedures use anesthesia every year. If you have a surgery or a procedure coming up, it helps to know the basics so you can feel calmer and make better choices. This page gives clear, practical info on the main types of anesthesia, common side effects, how to prepare, and simple recovery tips you can use right away.

Types of anesthesia and when they’re used

There are four common types you’ll hear about:

General anesthesia — You’re fully asleep and unaware during surgery. Used for major operations like abdominal surgery or certain orthopedic procedures.

Regional anesthesia — Numbs a large area of the body, like a spinal or epidural for lower-body surgery or childbirth. You may stay awake or get light sedation.

Local anesthesia — Numbs a small area. Dentists and minor skin or eye procedures often use this. You stay awake and alert.

Monitored sedation (conscious sedation) — You’re relaxed and may drift in and out of sleep, but you can usually respond. Common for endoscopies and minor surgeries.

Risks, side effects, and safety steps

Most people recover without problems, but anesthesia can cause side effects. Short-term issues include nausea, sore throat, shivering, dizziness, or mild confusion after waking up. More serious risks (rare) include allergic reactions, breathing trouble, or heart issues.

To lower risks, tell your care team about: all prescription drugs, over-the-counter meds, herbal supplements, alcohol use, and past reactions to anesthesia. That helps them choose the safest plan and avoid dangerous drug mixes.

Follow pre-op instructions exactly—fasting rules, which meds to stop, and arrival time. Fasting reduces the chance of vomiting and lung complications. If you take blood thinners, diabetes meds, or heart drugs, ask how to adjust them before surgery.

After your procedure, staff will monitor breathing, blood pressure, and pain. Expect to spend time in a recovery area until you’re stable. Don’t drive or make big decisions for 24 hours if you received sedation or general anesthesia.

Quick recovery tips: stay hydrated, walk a bit as soon as your team allows, use pain meds as prescribed, and watch for signs of infection at any incision sites. Call your doctor if you have high fever, increasing pain, shortness of breath, or prolonged confusion.

Want to feel more confident before your appointment? Write down questions for your anesthesiologist: what type you’ll get, why it’s chosen, specific risks for you, how pain will be handled, and what to expect after waking up. Good communication makes care safer and less stressful.
