Whether a liver cyst needs treatment is determined by the severity of the condition. If the diameter of the cyst does not exceed 5 cm and there are no physical abnormalities, no special treatment is needed; if the diameter of the cyst is greater than 5 cm or there are abnormal symptoms, treatment is required. Liver cyst is a relatively common liver disease in life, which is benign and often divided into non-parasitic and parasitic liver cysts, most of which are caused by abnormal bile duct development during the embryonic period. When the cyst increases in size, the patient will experience abdominal swelling and discomfort, as well as abdominal masses and pain, which can be examined and diagnosed by ultrasound or x-ray, or laparoscopy. If the cyst is small and asymptomatic, it is only necessary to go to the hospital for regular review to observe any changes in the condition. Ultrasound or CT is more reliable to diagnose liver cysts, no need to do other tests, avoid high-calorie and high-protein food in life, you can eat more oats, corn and other foods, you can work and exercise normally, and regular review is enough.
