I understand your hesitation - it took me six months to even consider the option of surgery (my primary care physician thought it was a good idea for me). Once I started going to the information meetings, I was confronted by so many things that could be alleviate or resolved by the surgery, it became obvious that I needed to do this for myself. Fortunately, I didn't have a lot of the co-morbidities of obesity like diabetes, sleep apnea, high blood pressure, etc. But I quickly realized that unless I did something serious about my weight, I was going to have those problems in the next few years.
Tomorrow will be 6 weeks since my surgery, and I feel great. Here's a list of the good and bad:
Bad
You have to re-learn how to eat.
If food is your friend and/or coping mechanism, you're losing it.
You may be tired for weeks.
If you don't follow the doctor's orders to a "t" you may throw up or get sick.
You can't sleep on your stomach for at least 6 weeks (I still haven't made it.)
Your breath is often bad, and body odor is stronger.
Many people start losing hair at about 3 months, and it stops at 6 months.
Many people have excess skin that may necessitate plastic surgery.
Good
You have to re-learn how to eat.
You're not hungry.
Your energy gets better each day, and finally one day, you feel back to "normal."
If you follow the doctor's orders, you will not be sick or throw up (I've been totally fine.)
Many people are immediately healthier and don't need their medications (for diabetes, high blood pressure, etc.) My husband says that I stopped snoring before I even got home from the hospital.
You will lose weight - pretty fast at first.
You feel lighter, more nimble, and flexible.
I have changed my association with food - I no longer need it to cope or to socialize. Food is no longer the most important thing in my life.
You have the peace of mind knowing that this is not a "diet" that will fail the moment that you assume your regular eating - it is a life change. So, get rid of those big clothes that don't fit any longer - you're never going to need them again.
Of course, all of these things are subjective. My experience is not the same as any others' experience. There are complications that can happen with surgery, and you may be sick through no fault of your own. But the chances of that are relatively slim, considering the seriousness of the surgery.
If you decide to do this, decide to do it right, and listen to everything that's said, read everything you're given (at least twice), and invest the time and effort to make this work for you.
Good luck with your decision!
