Gallbladder stones that hurt when you take a step and are relieved when you lie down may be caused by eating greasy food and dislocation of the stones. 1. Eating greasy food: bile has the function of breaking down fat in food into celiac particles, therefore, eating greasy food will stimulate the gallbladder to contract in order to discharge bile, and in this process, it will increase the contact friction between the gallbladder wall and gallbladder stones, so this symptom occurs. 2. Stone displacement: during walking, due to changes in body posture and position, the stones in the gallbladder are constantly and slightly displaced, resulting in increased contact friction between the stones and the gallbladder wall, the gallbladder wall is stimulated by the stones and breaks and bleeds, and even triggers gallbladder spasms, which is why this symptom occurs. Gallbladder stones hurt when you take a step and are relieved when you lie down, so you need to actively consult a doctor to clarify the cause of the disease and then carry out targeted treatment.
