Pantoprazol weightgain?

Has anyone put on weight on pantoprazol? I went from 83kg to over 93kg in less than 6 month. I first took 40mg pantoprazol every second day, then switched to 20mg every day, then back to 40mg every day. I also take 100mg tramadol and 16mg candesartan per day, so these may cause the weightgain too.
