My daughter is 4 years old. She recently had an abdominal ultrasound, and the report shows multiple gallstones in the gallbladder. The largest stone is 3.7 mm. All other organs like liver, pancreas, CBD, kidneys, and spleen are normal. She does not have abdominal pain, vomiting, or fever. But sometimes she has mild breathing difficulty. I want to know: Is a 3.7 mm gallstone in a 4-year-old child serious? Does she need any treatment or only monitoring? Is surgery needed at this stage? Can small stones dissolve or pass on their own in children? Is her occasional breathing issue related to gallstones or something else? What precautions or diet should we follow for her? What further tests (blood tests) should we do? How often should we repeat the ultrasound? Ultrasound impression: Cholelithiasis (multiple small stones).
