Ladies water retention and constipation as well as bloating are all side effects of the drugs and anthesthethics which is detailed in the paperwork.
I ate half a packet of Prunes and nuts or so a day and drank hot peppermint tea to ease discomfort and clear the bloat and drank a glass of water with pineapple juice every hour. I managed to get rid of the bloat by about day 4/5.
You can try that or up ur fibre intake by other means like a senakot capsule if constipated. Try not to eat much salt/salty foods as this will make it worse.
In many countries peppermint tea is drunk after a meal to ease digestion and bloating! If you don’t like the tea try hard boiled peppermint sweets. Hope that helps fxxx
