Whenever the gallbladder functioning decreases there is high chances of forming gallbladder sludge and gall stones. With Gall bladder sludge and stones there are higher chances of infections in biliary tree leading cholecystitis, cholangitis, pancreatitis so it s better to remove gall bladder when it s functioning decreased. In our practice we use to access gall bladder status in follow up in such patients and whenever there are gall stones or sludge in ultrasound or patients have discomfort with symptoms of gastroesophageal reflux(GERD) we convince the patient to go for cholecystectomy. In your case symptoms of GERD are present so you can follow up your doctor with proton pump inhibitors for symptomatic relief with regular sonography for gall bladder sludge, if your symptoms improve with medication and with no evidence of gb sludge or stone you can do better with medication alone otherwise if symptoms not relieved with or without gall bladder sludge/stone you can move forward for cholecystectomy.
