After internal hemorrhoid surgery, the thread will normally fall off in 7-12 days, and no later than 15 days. Of course this cannot be generalized, as the time varies from person to person with different physical conditions. The amount of hemorrhoid tissue ligated by the ligature wire will also affect the time, more tissue ligated, necrosis takes longer and may fall off later, less tissue ligated may fall off earlier, but no matter how early or late as long as there is no heavy bleeding when it comes off, that is normal. When changing the medication around 4-5 days after surgery, you can gently shake the ligature to prevent adhesions with the surrounding tissues and facilitate the smooth shedding of the ligature. You must keep your bowels open, drink more water, eat more fresh fruits and vegetables and high-protein foods to strengthen your nutrition, take more rest, avoid overworking and try not to do physical labor.
