Steps to take before the Surgery

Laparoscopic Weight loss surgery is complex surgery. The best preparation is to understand the risks and potential benefits and to closely follow our instructions.

Medications to avoid 2 weeks prior to surgery


Do not take Aspirin (acetylsalicylic acid) or products containing Aspirin such as:

  • Alka-Seltzer,
  • Anacin,
  • Antidol,
  • Apo-Asen,
  • Aspergum,
  • Asaphen,
  • Bayer Aspirin,
  • Astrin
  • AAS,
  • Bufferin,
  • Coricidin D,
  • Coryphen 325 or 650,
  • Darvon compound,
  • Dristan, Entrophen 5, 10 and 15,

Do not take anti-inflammatories unless otherwise instructed by your surgeon:

  • Advil,
  • Ibuprofen,
  • Celebrex,
  • Indocid,
  • Motrin,
  • Naprosyn,
  • Orudis,
  • Vioxx,
  • Voltaren

Stop taking all flu medications such as Tylenol Sinus, Advil Sinus, Reactine, cough syrup, etc. ;

Stop taking birth control pills ;

You should also avoid all natural and homeopathic products, garlic, vitamins and products that contain garlic. Despite their natural qualities, they may induce bleeding or delay healing.

Some new products or medications not listed above may also contain aspirin. When in doubt, consult your surgeon or pharmacist.

If you are taking heart, blood pressure, or diabetes medication, continue to do so until the day of your surgery. Do not take them before meeting with the anesthesiologist on the morning of your surgery. The anesthesiologist will determine which ones can be taken and which ones should be avoided.

You can however safely take certain medications such as Atasol and Tylenol to relieve pain.

Please note that it is your responsibility to verify if the medications you are taking contain or do not contain aspirin.

Alcohol and tobacco


Avoid alcohol consumption for one (1) week prior to your operation and two (2) weeks following your operation.  Combining alcohol and medications can cause unpredictable reactions and modify the effect of medications.

We strongly advise you to stop smoking for two (2) or three (3) weeks prior to your surgery as well as for the two (2) weeks that follow it.

Toxic substances in tobacco have a negative impact on blood circulation. These substances can cause small blood vessels to tighten and lead to skin loss (necrosis) in the area of intervention. These substances can also affect healing, as well as cause nausea, vomiting, and excessive coughing that increase the risk of bleeding after surgery as well as increasing the pain that you feel.

Nicotine substitutes (Nicorette, etc.) have the same harmful effects on blood circulation as smoking does and are therefore also inadvisable during this period.


Other important preparations

  • Remove artificial nails and nail polish as skin colour and nail colour are used as indicators to verify oxygen levels in the blood. Additionally, the device used to measure your oxygen level may not be able to read results if your nails are covered in polish or if you are wearing artificial nails.
  • Additionally, research has shown that nosocomial infections are transmitted primarily by the hands. Proper hand hygiene is therefore the most fundamental measure of prevention and control of infections for both staff members and clients. Wearing artificial nails and nail polish increases the amount of microorganisms and promotes the establishment of bacteria that can cause nosocomial infection.
  • If applicable (usually in men), you should, two days before your surgery date, remove hair in the operating area between your rib cage and the umbilicus with a depilatory agent (Veet , Vichy, Klorane, etc.). This type of product can be purchased at a pharmacy. Depilatory agents are irritating to the skin. Follow the instructions from the product’s packaging and ask your pharmacist for more information. Avoid waxing as well as razor blades.
  • Remove all jewelry, chains, earrings, rings, body piercings, and hair bands.

Special skin preparation

Take a bath or a shower the night before and the morning of surgery. In order to reduce the risk of infection and reduce the amount of bacteria on the skin during surgery and after surgery, use a sponge or a Chlorhexidine-based soap to wash the operating area. This product is available in pharmacies.
