Which of the following symptoms is NOT commonly associated with gallstones?

Gallstones can lead to various symptoms depending on whether they are causing complications. Abdominal pain is a common symptom, often described as a sudden onset of severe pain in the upper right quadrant of the abdomen, sometimes radiating to the back or right shoulder. Jaundice can occur if a gallstone obstructs the bile duct, leading to an accumulation of bilirubin in the blood, which gives the skin and eyes a yellowish appearance. Dark urine is also associated with this obstruction since elevated bilirubin levels are excreted in the urine, resulting in a darker color.

Weight gain, on the other hand, is not a symptom commonly linked to gallstones. While individuals may experience changes in appetite or diet due to discomfort from gallstones or related complications, weight gain itself is not a direct symptom of gallstones. Instead, gallstones may lead to weight loss in some individuals due to decreased food intake or the avoidance of certain foods that may trigger pain. Therefore, the presence of weight gain as an associated symptom is inaccurate in the context of gallstone-related conditions.
