Hemorrhoids are not once and for all non-recurring after surgery, if there are still predisposing factors, hemorrhoids may still reoccur or recur after surgery. The triggering factors for hemorrhoids are mainly the following: a. Anatomical reasons. When standing or sitting, the anorectum is compressed by gravity and organs, the upward reflux of veins is obstructed, blood is not easily returned, hemorrhoidal veins pass through the lax tissue of the submucosa, lack of stent fixation around them, and are easily expanded and flexed. Second, occupational relationship. Long standing or sitting affects venous reflux, hemorrhoid veins overfilled, stasis, expansion. Third, local stimulation and unclean diet. Cold, heat, constipation, diarrhea, excessive drinking and more spicy and irritating food can stimulate the anus and rectum, causing local congestion and impaired blood return, decreased resistance of the vein wall, and increased pressure within the hemorrhoidal vein. Fourth, increased intra-abdominal pressure, due to intra-abdominal tumors, prostate hypertrophy, pregnancy, overfed diet or constipation squatting toilets for too long, can increase intra-abdominal pressure, anal pressure, which hinders the blood return to the veins. So even after surgery for hemorrhoids, it is important to avoid the above factors in your daily life and work to prevent hemorrhoids from reoccurring or recurring.
