Obesity is a strong risk factor for gallstones, especially among women.Gallstones are clusters of solid material that form in the gallbladder. The most common type is made mostly of cholesterol. Symptomatic gallstones result in about 800,000 hospitalizations and more than 500,000 operations each year in the United States. People who are obese are more likely to have gallstones than people who are at a healthy weight. Obesity in adults can be defined using the body mass index (BMI), a tool that measures weight in relation to height. The table below shows how the BMI calculation works. A BMI of 18.5 to 24.9 refers to a healthy weight, a BMI of 25 to 29.9 refers to overweight, and a BMI of 30 or higher refers to obesity.
As BMI increases, the risk for developing gallstones also rises. Studies have shown that risk may triple in women who have a BMI greater than 32 compared to those with a BMI of 24 to 25. The risk may be seven times higher in women with a BMI above 45 than in those with a BMI below 24.
Researchers have found that people who are obese may produce high levels of cholesterol. This leads to the production of bile containing more cholesterol than it can dissolve. When this happens, gallstones can form. People who are obese may also have large gallbladders that do not empty normally or completely. Some studies have shown that men and women who carry fat around their midsections may be at a greater risk for developing gallstones than those who carry fat around their hips and thighs.
