Hi and welcome to Healthcare magic.Thank you for the query.
This is occasioaly experienced and you should be patient for few more months till your digestion adapt. Also, there can be postcholecystectomy syndrome which is rare complication of surgery,but there is no specific treatment necessary at this point. Just watch foryour diet,avoid alcohol,fat food and smoking
. Eat more frequently but smaller meals.
Wish you good health. Regards
