For gallstones of 1cm, if the patient does not have obvious symptoms of discomfort, he or she can take oral ursodeoxycholic acid or herbal medicines to activate the blood and dissolve the stones, and go to the hospital for regular review, with a low salt, low oil, light and nutritious diet. Although a 1cm stone is not very large, if at this time the patient has developed upper abdominal pain or nausea or vomiting, further treatment is needed. Such small stones can irritate the gallbladder in the long term and gradually increase in size over time, which can lead to inflammation and even cancer of the gallbladder, and therefore can be treated by surgical removal. Currently, laparoscopic cholecystectomy is commonly used in clinical practice. Attention must be paid to limiting the intake of foods high in cholesterol, such as egg yolk, duck meat, animal offal, etc.
