I had gastric bypass in Oct 2019, within the last 6 months (or so), I have been vaping THC pretty regularly. Slowly, I've had nausea feelings everyday. Some days worse than others (like today). At first I thought I'll just vape some more and this will take care of my nausea (like cancer patients will do for pain and nausea). Well, the nausea seems to be getting worse and I think there is a connection (duh). Has anyone else experienced this? Do you know if THC is NOT a good thing for bariatric patients? I'm going to stop for a week and see what happens. I'll keep you updated.

According to this: https://myhealth.alberta.ca/bariatric-surgery/after-your-surgery/smoking-vaping-and-drinking-alcohol-after-bariatric-surgery it says :

Can I smoke or vape after bariatric surgery?

It’s best not to smoke or vape any substance after surgery. This includes tobacco, tobacco-like products, and cannabis. These products can cause problems with your heart and lungs. Smoking after bariatric surgery can also cause stomach ulcers.

Why stop at a week? Keep going! I agree, drugs are a bad idea post weight loss surgery ?

I’ve not heard of this one yet. I’m curious to see what happens when you don’t smoke. Keep us posted for sure. I hope it’s as easy as just not smoking. Fingers crossed.

It might be the vaping that's causing the nausea. If you're unwilling to give up cannabis for more than a week, you could try edibles instead and see if that helps.

After seeing that vaping can cause stomach ulcers post op, I second the edibles idea. Have to time it right so it works as a snack too. ?

I just googled and if you want to make it yourself they even have low calorie edibles recipes online.

I have seen some on here post that edibles hit different and a lot stronger after bariatric surgery. But there are other products to try. Maybe try Tinctures? I have not tried marijuana since having my surgery. Also maybe try a ratio product. Like 1:1 THC:CBD. Those were awesome before surgery and did not give me the super high or nausea.

Cannabis hyperemesis syndrome is a thing. Likely has nothing to do with your surgery, just your use. It often starts with nausea and grows into recurrent vomiting. Mode of delivery doesn't matter, the only thing that resolves it is cutting it out. If you go a week without and the nausea resolves, you'll have your answer.
