Gallbladder stones 5mm usually do not require surgical treatment, observation treatment is sufficient. This is because for a single stone with a diameter of 3 centimeters, observation treatment can be carried out, and abdominal ultrasound or abdominal CT can be repeated every 3 months to see the change in the diameter of gallbladder stones. If the diameter of gallbladder stones is more than 3 centimeters, there is a risk of cancer, inducing gallbladder cancer, and surgical treatment is needed to take out the gallbladder stones. For patients with multiple gallbladder stones, since the gallbladder stones fill up the gallbladder and act on the gallbladder for a long period of time, they are also prone to gallbladder and gallbladder cancer, and surgical removal of the gallbladder is needed to treat the disease. Patients with gallbladder stones should pay attention to their diet, eat more fresh vegetables and fruits, avoid high protein and high fat foods, and consult a doctor if they feel unwell, so as not to miss the best time for treatment.
