I received gastric sleeve in 2019 and was doing really well until covid hit. I lost my job and staying home when it first hit really made me depressed. Now I cant lose any weight i just keep gaining and gaining. Im trying to get some advice on if i should get revision surgery or bypass.

First of all, I just want to say I'm sorry you're struggling and I hope you know you're not alone. The last 2 years have been brutal for a lot of us and there is no shame in any if it.
That being said, before you move on to revision/bypass, have you reached out to your surgery center and/or dietitian? They should be able to offer some guidance on how to get back on track. Most suggest going back to the basics: weigh and track everything, prioritize protein, get your fluids in, move your body everyday, etc. If they aren't helpful or available to you, maybe ask your PCP for a referral to an RD? Sometimes we just need someone to point us in the right direction. Also, have you gotten support for your mental health & wellbeing? Making sure you've dealt with the junk internally is SO important. If not, that might be a really good place to start. A few sessions of therapy can go a LONG way. Maybe do some reading on emotional eating or whatever patterns you find yourself falling into. Knowledge is power!
Revision is always an option, and there is absolutely no shame in pursuing it. But it's not the only option. You already have the tools, maybe you could benefit from some guidance in how to start using them again? Whatever you decide, we wish you the best!
