The Truth About Gallstones: Prevention, Treatment


Q. I just found out I have gallstones. Should I be following a special diet?

A. That depends. Gallstones are solid clumps of mostly cholesterol that form in the gallbladder, which stores and releases bile into the intestine to aid digestion. Gallstones can be as small as a grain of sand or as big as a golf ball. Most are asymptomatic, so-called "silent" gallstones, and require no treatment.

Diet Rx. Roughly 20% to 40% of gallstone sufferers have symptomatic stones and need to cut back on fat in order to prevent discomfort or pain. Eating fat-containing foods signals the gallbladder to contract. Depending on the size of the stones, these contractions may bring on pain.

But the traditional "one-size-fitsall" 40-gram-a-day fat diet is difficult to follow and doesn't account for differences in calorie needs and body size. Leslie Bonci, M.P.H., R.D., spokesperson for the American Dietetic Association, advocates an individualized eating plan with 25% of calories from fat. In addition, most people find they tolerate small, frequent meals better than two or three large ones. If these diet strategies don't help, consult your doctor; surgery may be indicated.

Historically, a low-fat diet has also been prescribed after having a gallbladder removed. Now, doctors generally give the green light to resume a normal diet within a month.

What causes gallstones in the first place? Several theories exist.

Link to Overweight. Several studies have shown that obese women have at least twice the risk of gallstones as lean women. However, crash dieting is not a solution. In fact, it may be part of the problem. Going for long periods without eating and skipping breakfast-practices common among dieters--decreases gallbladder contractions. If the organ doesn't contract often enough to empty out bile, then stones can form.

Link to Vitamin C. Not getting enough vitamin C may also predispose you to gallstones. Research shows that women with high blood levels of vitamin C have less gallbladder disease than women with lower levels. Vitamin C helps break down cholesterol into bile acids for excretion, making them unavailable to form stones. Eating lots of C-rich fruits and vegetables should, then, help protect against gallstones.
