What Causes A Bowel Obstruction?
Gallstones

Gallstones are hard deposits that form in the gallbladder. The deposits are usually composed of undigested cholesterol. While some patients may experience no symptoms from their gallstones, other patients could experience intense pain in the center or upper right quadrant of the abdomen, and pain may also develop in the right shoulder or between the shoulder blades. Gallstones are more likely to develop in individuals who are forty years old and older, and they are more common in women. Eating a diet high in fat or cholesterol could increase the risk of gallstones, and patients who are overweight or obese are at an elevated risk as well. To diagnose gallstones, doctors usually start with an abdominal ultrasound, and an endoscopic ultrasound might be performed as well. Some patients may need to have an endoscopic retrograde cholangiopancreatography procedure. Treatment is generally recommended for symptomatic patients, and surgery to remove the gallbladder is the most common treatment. If patients cannot have surgery, they may be offered medications to dissolve the gallstones.
