How do I no if I have gallstones and what causes it? Would this make my liver enzymes elevated?

See Dr & get U/S . Ultrasound rapidly identifies most persons with gallstones. Ct or functional imaging (hida / mrcp) can id others. Some people retain 'sludge' in their gb, and this eventually starts crystalizing / stone formation. Concern being obstruction of outflow / infection / pain. Ask your dr or a surgeon.
