Procedure prep
Fasting Before Varicose Vein Surgery
Varicose vein treatment is usually a day-case procedure, so you should be home the same day. How you prepare depends a lot on which type of anesthesia your team is using, so the first thing to nail down is whether you'll be awake or asleep.

Medicines to check
- Blood thinners (aspirin, clopidogrel, warfarin, Eliquis, Xarelto) — these affect bleeding and bruising and need a plan. See medications to stop.
- Estrogen-containing pills (combined contraceptive or HRT) raise clot risk & are sometimes paused before vein surgery — ask your team well in advance.
- Diabetes medicines & insulin — they need a plan, especially if you're fasting. See diabetes tablets.
- Blood pressure medicines — confirm which to take with a sip of water on the morning of surgery.
- Anti-inflammatory painkillers (ibuprofen, naproxen and other NSAIDs) can increase bruising — ask whether to avoid them beforehand.
When this surgery may be delayed
- Fever, a new cough/cold, or a chest infection
- Vomiting or diarrhea in the day or two before
- A new skin infection, broken skin, or ulcer over the treatment area
- An active blood clot (DVT) or recent unexpected leg swelling
- A positive or unknown pregnancy test
Reports & documents to carry
- Photo ID and your insurance or hospital paperwork
- A list of all your medicines and doses (including supplements)
- Any leg ultrasound (vein mapping/duplex scan) results or referral letters
- Loose trousers and your prescribed compression stockings if you already have them
- A planned ride home and an adult to stay with you if you'll have sedation or a general anesthetic
What to ask your anesthesia team
- Will I be awake under local anesthetic, or have sedation or a general/spinal — and do I need to fast?
- Which of my regular medicines should I stop, and which do I take on the morning?
- When can I eat and drink afterward, and when can I drive again?
- Will I go home the same day, and do I need someone to collect me?
- How long do I wear compression stockings, and how soon should I start walking?

Frequently asked questions
Will I be awake during varicose vein surgery?
Often, yes. Most modern treatments — laser (EVLA), radiofrequency, and foam injections — are done under local anesthesia, so the leg is numbed but you stay awake, sometimes with light sedation to help you relax. Traditional stripping is more commonly done under a general or spinal anesthetic. Your team will tell you exactly which applies to you.
Do I really need to fast for varicose vein surgery?
It depends entirely on the anesthesia. For treatments under local anesthetic only, fasting is often not required, though some teams still prefer you not to eat beforehand. If you're having sedation, a general, or a spinal anesthetic, you'll follow the standard fasting times. Always go by the specific instructions your team gives you.
Why do I have to wear compression stockings and walk afterward?
Compression stockings press gently on the leg to reduce swelling and bruising and help the treated veins close down, while walking keeps your blood moving and lowers the small risk of clots. Most people are encouraged to get up and walk soon after the procedure. Your team will tell you how many hours a day to wear the stockings and for how many weeks.
How soon can I drive and get back to normal?
If you've had only local anesthetic you may be able to resume light activity quite quickly, but you must not drive yourself home on the day of any sedation or general anesthetic. Many people return to gentle daily activities within a day or two and avoid heavy exercise for a short while. Follow the specific timeline your team gives you.
