After gallbladder removal you still have bile ducts. If by feeling the gallbladder you mean feeling the same kind of problems as before, they may be caused by small stones or biliary sludge sticking in the bile duct...
After gallbladder removal, bile is constantly flowing into your intestine, and sometimes not all can be re-absorbed in the distal part of the small intestine, so it reaches the colon and irritates it. This can cause diarrhea. To prevent this, you can try:
- dividing mealsin small portions
- avoiding fat-rich foods
- adding some fibres like Metamucil or Citrucel to meals. Fibres bind some bile acids and prevent irritation of the colon.
If above doesn't help, you can try low-fodmap diet:
