Patients with liver cysts can eat bird's nest. Bird's nest is a type of food relatively rich in nutrients and can be consumed at this time. Additionally, patients with liver cysts should mainly avoid spicy and stimulating foods, such as chili peppers, barbecue, and garlic. A light diet, focusing on fresh vegetables and fruits, should be adopted to better control the condition. Generally, patients with smaller liver cysts will not experience significant symptoms and do not need special treatment; regular ultrasound check-ups are sufficient. However, patients with larger liver cysts may experience local compression symptoms or even liver function abnormalities, so early surgical removal and treatment are advised for a better prognosis.
