Dietary contraindications after varicose ligation are as follows: 1. Before the vein completely disappears or becomes smaller, re-bleeding needs to be prevented. The ulcer surface is formed during the process of skin ring shedding, which can cause the ligature ring to fall off and induce bleeding due to improper diet, so the intake of rough and hard food, such as pancakes, large lean meat and nuts, should be avoided; 2. 8 hours of fasting after surgery, and gradually resume semi-liquid diet. Before the varicose veins are completely controlled and the ulcers caused by the venous ligature ring disappear or heal, semi-liquid food, soft food and easily digestible food should be the mainstay when reviewing the gastroscopy.
