If I have gallbladder removal surgery, how long does it take to recover? What are the after-effects? Usually 1-2 days of postoperative clinical observation, no problems are discharged on the 2nd postoperative day, and stitches are removed one week after surgery. Fatty diarrhea may occur after surgery because there is no storage function of the gallbladder, and diarrhea may occur after eating fats that are beyond the digestive capacity of the bile. Each person has a different concept of recovery, and full recovery to pre-operative status varies from person to person. After surgery, it is still recommended to eat a balanced diet and try not to consume too much fat and cholesterol at once.
