Hello and hope you are doing well.
After gall bladder removal there could be intolerance to fatty food. But this is unlikely to cause severe spasms. Sometimes the pain could be due to gastroenteritis, which is infection of the intestines. Amoebiasis is another infection, which can cause similar symptoms. Other common causes are constipation and indigestion. Some inflammatory bowel diseases like diverticulitis and crohn’s disease can produce similar symptoms. Here the walls of the intestines are swollen. You will need to consult your primary care physician, who may run blood, urine and stool tests and may sometimes ask for an ultrasonogram to detect the cause for the pain.
Hope this helped and do keep us posted.
I would definitely report this to your doctor to let them know the issues you are having. Follow up and let us know how you are doing and if your symptoms have gotten any better.
