My weight has remained between 146 to 148 since last summer. Recently I quit smoking (for the 1000th) time and my weight jumped up, seems like overnight to mid 150's. With that said I understand your concern. Scarey, scarey, scarey!
I told myself that I would not allow my weight to go above 150. Soooooooooo, I am back on my post surgery plan to get back to my fighting weight. No, it's not a big deal (I'm 5'9") but I know from my history that 5 lbs can turn into 15 lbs and on and on and on, so I am taking this seriously and handling my business now. Plus I have some upcoming events where food is crazy plentiful so I need to get this off to get my leeway back, but I will update you by the end of the month.
Good luck to you too......
