Hello Welcome to Ask a Doctor service I have reviewed your query, and here is my advice Let me inform you that passing a stool three to four time in day could be normal one and most of the time diet is responsible for that and here in this case gall bladder surgery has nothing to take anything, so in my opinion try to change the diet, avoid taking spicy food, heavy meal, oily food, swelling of body could be nonspecific, if not complain of breathing difficulty is there, urine out put is ok then it is nothing to worry. Hope I have answered your query, let me know if I can assist you further.
