Symptoms of gallstones include pain and pressure in the upper-right area of the stomach, according to WebMD. However, approximately 80 percent of people with gallstones do not experience any symptoms, according to the American College of Gastroenterology.
In addition to the upper area of the stomach, pain caused by gallstones may also localize in the chest or right shoulder, explains the American College of Gastroenterology. Nausea, vomiting, bloating, gas and indigestion are additional symptoms of gallstones, states WebMD.
An onset of symptoms may make it difficult to breathe normally or get comfortable, although moving around does not alleviate symptoms, indicates WebMD. Pain may last up to 24 hours, although pain episodes lasting one to five hours are most common. An episode that exceeds one to two hours, or is accompanied by a fever, requires immediate medical attention, instructs the American College of Gastroenterology.
Complications associated with gallstones include blood, bile duct and gallbladder infections, notes the American College of Gastroenterology. Additional complications include jaundice of the skin and eyes, as well as inflammation of the pancreas
Women between 20 and 60 years of age are three times more likely than men to develop gallstones, states the American College of Gastroenterology. Risk factors for the development of gallstones include obesity, multiple pregnancies, Hispanic or American Indian heritage, rapid weight loss, and family history of gallstones.
