Mason,
Firstly, welcome to the forum.
Sweetheart - this is an ideal time to start writing down questions for your surgeon. Have a scrap of paper with you always.
You know, I live just outside a town with 86 people. I know most of them well and when I mentioned to a few that I was thinking of having weight loss surgery, just about every single one of them came back with a tale of knowing someone who had a aunt who knew someone whose cousin's niece had the surgery - and died. I was told some horrendous stories which were patently born out of total ignorance of the WLS process.
Obesity itself brings an increase in Nonalcoholic Fatty Liver Disease. 85%-95% of all morbidly obese people will have it.
The good news is that gastric bypass improves liver histology in patents with NAFLD. This is just one article - there are plenty if you search gastric bypass improves liver disease

You know the risks to your health that being overweight brings. High blood pressure, diabetes, heart conditions... the list goes on and on.
The good news is that losing weigh will drastically reduce if not totally eliminate these diseases.
Bottom line - only you can decide. Just make sure you research it fully and if it means giving your surgeon the third degree, then do it - most are pretty impressed when they have a patient turn up who has done some homework.
Best of luck to you with your decision.
