These are all good points, number 1 reason to avoid NSAIDs is gastric ulcers. There have been studies that show prolonged exposure to NSAIDs can cause ulcers and even increase acid reflux which is an issue especially with sleeve patients and may result in a second surgery to preform a roux en y to prevent reflux or fix ulcerations. I have seen over 2000 surgeries and each patient is different. Asking your doctor is key when consuming these or any medication. On average most surgeons do allow use sparingly but on need based cases usually. Someone mentioned advil due to a slight infection at the IV site, which is generally helpful in preventing full inflammatory responses such as cellulitis or thrombophlebitis. It may not hurt for one time use but please don’t put yourself at risk and continue use without consulting your surgeon. As one of the unlucky ones with a roux en y conversion that actually resulted in a full gastronomy (stomach removal) and 3 extra Anastomosis points, (connections of colon to other parts like colon or esophagus) 25 years in medicine and proof that everyone is different. Yes I did have permission to use excedrine as I was allergic to most all other NSAIDs, I did not follow instructions and used daily vs sparingly. 5 years later I am 3 months out from the most terrifying experience of my life. The surgeons I work with saved me but now I know it’s better to ask them then a forum. Even if your background is medical.
