What are the symptoms of gallstones?

Prognosis and course of disease

Gallstones produce symptoms in about 50% of people who have them. The greater is the likelihood of reporting symptoms in younger people compared to people older than 60 years.
Most spectacular symptom which gallstones produce is biliary colic. It is presented as a strong, constant, dull pain in the upper right quadrant of the abdomen or under the right costal arch. Pain begins suddenly, lasts a few hours, and then you have a feeling of dull pain for the next 24 hours. Patients are often unrest and are looking for the position of the body which would reduce the pain. Pain can expand under the right shoulder blade.

Obstruction of bile ducts can lead to inflammation of gall bladder, cholecystitis. As a result of acute inflammation of the bladder there may occur bladder hydropsy, gangrene and perforation of bladder.
