Medications Post Bariatric Surgery

This is a question which all patients should ask as it could affect them after their weight loss surgery.

OTC and Prescription drugs can be absorbed differently after your bariatric surgery.  It really depends on the exact procedure that you had.  It’s important to be aware of this.  Right after your weight loss surgery, if you have had the lap band procedure, it will be recommended that you do not take pills as they could become trapped in your band.  There are different forms of medication such as liquid form or you can crush your pills.  If they pill tastes terrible, it can be taken with food at the same time.

VSG patients do not have to worry about the absorption of medications as it will have little to no change in the absorption post op.  Gastric Bypass patients and Duodenal Switch patients will have a more significant change in how your body absorbs medications after surgery and a higher dose of medications may be administered by your Dr. to counter-balance this.  You need to be vocal and let your Dr. know your worries and concerns.  All changes in your medications need to be discussed with your GP as this is not something you should be doing by yourself.

It is advised by most surgeons to avoid taking NSAIDS (non steroidal anti-inflammatory drugs) after Gastric Bypass surgery as this can lead to stomach irritation and ulcers – and consuming these medications can lead to a Marginal Ulcer which can bleed or perforate.  These types of ulcers are repairable and not fatal but they can cause months of problems.  There are alternative medications which can be taken with less chances of complications.

Post surgery most patients will require an antacid prescribed for 4 to 6 weeks post op weight loss surgery.  If your surgeon prescribes this for you, please do take it.  It will help with healing and reduce the amount of acid with your tummy produces.

Check with your Surgeon to be sure of his/ her rules and regulations for medications before you have bariatric surgery in order to be well prepared posts operatively.
