The incidence of gallstones in women is twice that of men. Obesity and rapid weight loss are risk factors for gallstones. Previous studies have shown that the incidence of gallstones in men who have the habit of drinking coffee is lower. Now, a study by Harvard University in the United States shows that women who drink four cups of coffee a day are also less likely to suffer from gallstones. Researchers believe that caffeine is an effective ingredient in coffee to reduce the incidence of gallstones, because experimental evidence has shown that caffeine can promote gallbladder contraction, thus preventing gallstones from forming in the gallbladder.

Mind you, drinking coffee can prevent gallstones. This folk prescription comes from the internet. Please follow the doctor's advice before use.
