Effects (weight gain) from extended antibiotics?

I've done a fair bit of research and study on it myself, but other than the fact that antibiotics mess with our systems, there seems to be hit and miss opinions on whether extended antibiotics can affect our weight.

Over the past 12 months, I was on antibiotics for a total of approximately 180 days due to surgeries (4) and a hardware infection on one of the plates (which was removed on surgery #4). This included 6 weeks of 3x/day IV antibiotics.

I took a good probiotic once the infection issues popped up, and stayed on that for about a month after getting off antibiotics.

I noticed, however, that after quitting the antibiotics (and shortly thereafter starting working out again), weight seemed to start creeping on. I'll admit, I wasn't counting calories, and only got back to that last week. Yes, there was muscle being put back on, and there are noticeable gains in my atrophied leg, but that still can't account for much.

After getting back into a deficit, I did lose a little, and my system doesn't feel messed up, but I'm just curious on any other anecdotal stories people may have from being on long term antibiotics.
