When internal hemorrhoids flare up, if their size increases and obstructs the anal opening, it can prevent normal defecation or make it difficult, potentially causing symptoms of constipation such as difficulty in defecating or poor bowel movements. Prolonged and recurrent difficulty in defecating can also lead to overly dry stools within the intestinal lumen, further exacerbating symptoms of constipation. Therefore, constipation is one of the most common clinical complications of hemorrhoids. To treat constipation, one can initially choose oral medications that lubricate the intestines and facilitate bowel movements. At the same time, it is essential to actively treat hemorrhoids, reduce the size of the hemorrhoidal tissue, or directly remove both internal and external hemorrhoids, to enable normal expulsion of stool.
