Alcohol. A few studies have reported a lower risk for gallstones with alcohol consumption. Even small amounts (1 ounce per day) have been found to reduce the risk of gallstones in women by 20%. Moderate intake (defined as 1 - 2 drinks a day) also appears to protect the heart. It should be noted, however, that even moderate alcohol intake increases the risk for breast cancer in women. Pregnant women, people who are unable to drink in moderation, and those with liver disease should not drink at all.
Coffee. Research suggests that drinking coffee every day can lower the risk of gallstones. The caffeine in coffee is thought to stimulate gallbladder contractions and lower the cholesterol concentrations in bile. However drinking other caffeinated beverages, such as soda and tea, does not seem to have the same benefit.
Preventing Gallstones during Weight Loss
Maintaining a normal weight and avoiding rapid weight loss are the keys to reducing the risk of gallstones. Taking the medication ursodiol (also called ursodeoxycholic acid, or Actigall) during weight loss may reduce the risk for people who are very overweight and need to lose weight quickly. This medication is ordinarily used to dissolve existing gallstones. Orlistat (Xenical), a drug for treating obesity, may protect against gallstone formation during weight loss. The drug appears to reduce bile acids and other components involved in gallstone production.
The Effects of Cholesterol-Lowering Drugs
Although it would be reasonable to believe that drugs used to lower cholesterol would protect against gallstones, most evidence has found no gallstone protection from these drugs. Reducing blood cholesterol levels does not have any effect on cholesterol gallstones.
