After three years of gallbladder removal, when you eat food containing a lot of oil, you have constant hidden pain, mainly because after gallbladder removal, the digestion and absorption function of fatty foods is reduced, and when you eat food containing a lot of oil, you cannot fully digest and absorb it, and symptoms of indigestion occur, which in turn leads to hidden pain. The main function of the gallbladder is to concentrate and store bile, which is a kind of digestive fluid that can promote the digestion and absorption of lipids. Three years after cholecystectomy, the patient has constant pain when he eats oil-containing food because the digestion and absorption of lipids is impaired after the gallbladder is removed, and it is easy for the patient to suffer from indigestion when he eats oil-containing food. Patients after cholecystectomy should pay attention to try to avoid eating food containing more oil, eat more fresh vegetables and fruits to avoid indigestion. When abdominal pain occurs, you should go to the hospital in time, clear the cause of the disease and then actively treat it, so as not to miss the condition.
