Hang on a sec, you're only 2 weeks post op and shouldn't be taking ANYTHING without checking with one of your team first. Your intestines have just been completely rewired and throwing tablets of any size down without proper medical advice first is foolish.
It's not just the risk of the tablet getting stuck, it's to do with the risk of irritation to the intestines and how the laxatives work on the bowels. Most, like senna, cause your bowels to spasm and cramp to move things along as well as affecting the water balance, and this can be dangerous when you are early post op.
There are a lot of other options which are safer, and should be discussed with your team or GP. Lactulose, although gross, works well. Movicol (prescription) is a bit stronger and less sweet. Benefibre/fibresure should be taken in addition to anything else as a precautionary method to stop problems re-occuring, although if you take this and don't drink enough fluids it can contribute to constipation. If you are very constipated or impacted you can get enemas from your GP which work instantly and are safe to use.
No-one on here should be telling anyone what tablets/medicines are safe to use post op in the early days, we're not bariatric specialists and you shouldn't take anyones word that things are safe.
