Prevention
There is no sure way to prevent
gallstones. But you can reduce your risk of forming
gallstones that can cause symptoms.
Maintain a healthy weight
Stay close to a healthy weight. Research shows that intentional
weight loss (dieting, not weight loss from illness) followed by unintentional
weight gain may increase your risk for forming gallstones, especially if you
are a woman.3 If you need to lose weight, do so
slowly and sensibly. When dieting, aim for a weight loss of only
0.5 kg (1 lb) to
0.7 kg (1.5 lb) per week. For
more information, see the topic
Healthy Weight.
It is also important to avoid rapid weight loss and starvation
diets. If you are on a rapid weight-loss diet, it is recommended that you be
under a health professional's care. You may want to ask your health
professional about taking medicines to help reduce your chances of developing
gallstones while you are on such a diet.
Eat regular, balanced meals
Research shows that eating regular meals that contain some fat
(which causes the gallbladder to empty) can help prevent gallstones. Eat plenty
of whole grains and fibre, and have regular servings of food that contain
calcium (found in green, leafy vegetables and milk products). Limit saturated
(animal) fat and foods high in cholesterol.4
Exercise regularly
Increased levels of physical exercise also may be an important
way to reduce your risk of forming gallstones. One study has shown that women
who exercised regularly decreased their risk of having to have the gallbladder
removed. Exercising 2 to 3 hours per week reduced the women's risk by
20%.5
In a large study of men, 2 to 3 hours of moderate running per
week reduced by 20% the risk of forming gallstones that cause symptoms.6 Along with eating a low-fat diet, exercise is also an
effective way to help you stay close to a healthy weight and lower your
cholesterol and
triglyceride levels.
Deciding whether to take estrogen
Some evidence shows that taking hormones such as
estrogen after menopause or taking high-dose birth
control pills may increase a woman's risk of forming gallstones that cause
symptoms.1 If you are taking such hormones, talk
with your health professional.
