Not everyone who has gallstones has symptoms. When gallstones block the flow of bile — even temporarily — you may develop pain and other symptoms. If the gallstones move, symptoms usually stop. Symptoms of a gallbladder attack include:
Abdominal pain, especially in the middle or upper right part of your belly.
Back pain.
Bloating.
Fever.
Light-colored urine or stools (poop).
Nausea.
Vomiting.
Yellow eyes or skin (jaundice).
Gallbladder attack symptoms are most likely to occur after you’ve eaten a meal that includes rich or high-fat foods. Symptoms may develop within an hour or two after eating. Pain may wake you up during the night after a heavy meal.
